    88

    Hyde Park is a plateau almost in the centre of the city, which in the early days of Sydney was used as a race-course.

    89

    Igneous intrusions consist only of unimportant dikes of trap. The most striking and uniformly characteristic geologic feature of the mountains is their internal structure, consisting of innumerable parallel, long and narrow folds, always closely appressed in the eastern part of any crosssection (Piedmont Plateau to Great Valley), less so along a central zone (Great Valley and Valley Ridges), and increasingly open on the west (Allegheny and Cumberland Plateaus).

    In a north-eastern section, practically all of New England is occupied by the older crystalline belt; the corresponding northern part of the stratified belt in the St Lawrence and Champlain-Hudson valleys on the inland side of New England is comparatively free from the ridge-making rocks which abound farther south; and here the plateau member is wanting, being replaced, as it were, by the Adirondacks, an outlier of the Laurentian highlands of Canada which immediately succeeds the deformed stratified belt west of Lake Champlain.

    92

    In a south-western section the crystalline belt again assumes importance in breadth and height, and the plateau member maintains the strength that it had in the middle section, but the intermediate stratified belt again has fewer ridges, -because of the infrequence here of ridge-making strata as compared to their frequency in the middle section.

    93

    In addition to being a forest the Ardennes is a plateau, and it offers to the geologist a most interesting field of investigation.

    94

    In certain parts of the plateau there are narrow anticlinal uplifts, an outlying effect of mountain-making compression; here a ridge rises if the exposed strata are resistant, as in Chestnut ridge of western Pennsylvania; but here a valley is excavated if the exposed strata are weak, as in Sequatchie Valley, a long narrow trough which cuts off a strip of the plateau from its greater body in Tennessee.

    112

    In the Mountain Region and in the Piedmont Plateau Region the rivers have numerous falls and rapids which afford a total water power unequalled perhaps in any other state than Maine on the Atlantic Coast, the largest being on the Yadkin, Roanoke and Catawba; and in crossing some of the mountains, especially the Unakas, the streams have carved deep narrow gorges that are much admired for their scenery.

    113

    117

    In the north-west are the southern slopes of the volcano Merapi, and in the east the Kidul hills and the plateau of Sewu.

    118

    In the Piedmont Plateau and Appalachian Mountains Regions the surface soil is generally sandy, but in considerable areas the subsoil is a red clay derived largely from the decomposition of hornblende.

    119

    129

    It appears, however, from Russian explorations during the last third of the 19th North- century, that it has all the characteristics of an elevated western plateau, of a rhomboid shape (like Bohemia), bounded by four mountain ranges; namely, the Russian Altai on the N.W., the Sayans on the N.E., the Kentei range on the S.E., and the Ektagh Altai on the S.W.

    130

    It collects nearly all the drainage of the Udaipur plateau with that of the eastern slopes and hill-tracts of the Aravallis, and joins the Chambal a little beyond the northeastern extremity of the Bundi state, after a course of about 300 m.

    133

    It formerly abounded in sandalwood, and consists of a central plateau surrounded by a belt of cultivation.

    134

    It includes an immense high and broken plateau which spreads from south-west to north-east, losing in width and altitude as it advances north-east.

    135

    It is a peculiar feature of the drainage in North Carolina that the headwaters lie to the east of the highest mountains, and that the chief rivers flow north-westward through the mountains to the broad valley lowland of the stratified belt and then through the plateau, as the members of the Mississippi system.

    136

    147

    It naturally falls into two divisions, the northern being more or less mountainous, while the southern is flat and marshy; the near approach of the two rivers to one another, at a spot where the undulating plateau of the north sinks suddenly into the Babylonian alluvium, tends to separate them still more completely.

    148

    It rises near the peak of Itatiaya, on the northern slopes of the Mantiqueira, and flows north-west and west across the Minas plateau, receiving several large tributaries from the south.

    149

    It stands on a narrow plateau of ground supported on the south-east by a terrace wall.

    150

    It was the main entrance on the north, and no doubt is to be identified with the so-called Scala Greca, where the modern highroad leaves the plateau.

    151

    It was, in fact, an island city in an estuary of the Persian Gulf, stretching up into the Arabian plateau.

    152

    Its general elevation is less than that of the Sao Francisco region, owing to the slope of the plateau surface toward the Amazon depression and to denudation.

    153

    Its inner border affords admirable examples of topographical discordance where it sweeps north-westward square across the trend of the piedmont belt, the ridges and valleys, and the plateau of the Appalachians, which are all terminated by dipping gently beneath the unconformable cover of the coastal The, lain strata.

    154

    Its semi-arid character is due to the mountain ranges on its northern frontier, which extract the moisture from the north-east trades and leave the Brazilian plateau behind them with a very limited rainfall, except near the Atlantic coast.

    155

    Its southern extremity penetrates into the high plateau of Asia, and the lake lies entirely in the Alpine zone which fringes that plateau on the north-west.

    156

    Its summit consists of a plateau too acres in area, with a slight slope to the south, terminating on its north-eastern side in a sheer fall of more than 1500 ft.

    157

    Its surface is a roughly broken plateau, traversed N.W.

    158

    Its territory is divided into two nearly equal parts by the eastern branch of the Sierra Madre Occidental, the northern part belonging to the great central plateau region, and the southern to an extremely broken region formed by the diverging branches of the Sierra Madre, with their wooded terraces and slopes and highly fertile valleys.

    159

    Its waters are lost in the arid stony plateau of the Sorl.

    160

    Kutusovwaspursuing this march to the southwest when he was surprised by the swift advance of Soult's men on the plateau itself.

    161

    Large areas of the plateau are covered with grass and occasional thorn trees.

    162

    Lemberg is situated on the small river Peltew, an affluent of the Bug, in a valley in the Sarmatian plateau, and is surrounded by hills.

    163

    Long droughts are common in many parts of the country, and on the barren surfaces of the plateau the rains drain away rapidly, leaving but slight beneficial results.

    164

    Many of the inhabitants are nominally Moslems. The greater part of the province may be said to consist of an extensive plateau, generally from 5000 to 7000 ft.

    165

    Many well-defined channels, cutting across the north-sloping spurs of the plateau in the neighborhood of Syracuse, NY., mark the temporary paths of the ice-bordered outlet river.

    Menelek, by means of Count Antonelli, resident in the Shoa country, requested Italy to execute a di version in his favor by occupying Asmar and other points on the high plateau.

    167

    Mr Gardiner regarded these banks as plateaus rising to different elevations beneath the surface of the sea from a main plateau rising steeply from the great depths of the Indian Ocean.

    168

    Near the 10th parallel the great chain again divides, the eastern part crossing the southern end of the plateau, and the western, or Sierra Madre del Sur, following the shore line closely to Tehuantepec. The Sierra Madre Occidental has but few noteworthy elevations, its culminating points being the Nevado de Colima (14,363 ft.) and Volcan de Colima (12,750 ft.) in the state of Jalisco.

    169

    Near the Colorado river the dissected cuesta of the Grand Prairie passes southward, by a change to a more nearly horizontal structure, into the dissected Edwards plateau (to be referred to again as part of the Great Plains), which terminates in a maturely dissected fault scarp, 300 or 400 ft.

    170

    New York, where the Appalachians enter the state, the plateau becomes much higher than in the W., reaching its culmination in the Catskills.

    171

    No further attempt was made on the plateau, which was held by the French from Pratzen to the Olmiitz road.

    172

    North of the plateau rises a well-watered and undulating belt of country, into which run low ranges of limestone hills, sometimes arid, sometimes covered with dwarf-oak, and often shutting in, between their northern and north-eastern flank and the main mountain-line from which they detach themselves, rich plains and fertile valleys.

    173

    North of the Sao Francisco the watershed projecting from the plateau eastward toward Cape St Roque, known as the Serra da Borborema in Parahyba and Rio Grande do Norte where its direction becomes north-east, leaves a triangular section of the easterly slope in which the river courses are short and much broken by rapids.

    174

    North of this line is the low hilly country, known as the Waldviertel, which lies at the foot and forms the continuation of the Bohemian and Moravian plateau.

    175

    Nuevo Leon lies partly upon the great Mexican plateau and partly upon its eastern slopes, the Sierra Madre Oriental crossing the state N.W.

    176

    Of these three natural divisions the plateau possesses the most fertile soil, generally of the kind known as "black cotton," but the low-lying plain has the densest population.

    177

    On a plateau above the river, the favourite promenade of the citizens, stands the Vladimir monument (1853) in bronze.

    On an average the coast-belt temperatures are some 10 0 higher than those of the plateau.

    179

    On both sides of the central ridge deep troughs extend southwards from the Telegraph plateau to the Southern Ocean, the deep water coming close to the land all the way down on both sides.

    180

    On its northern aspect this plateau has a raised rim having all the appearances of being once the margin of an atoll.

    181

    On reaching the Tibetan plateau, with the increased dryness the flora assumes many features of the Siberian type.

    182

    On the 28th of March 1888 the negus indeed descended from the Abyssinian high plateau in the direction of Saati, but finding the Italian position too strong to be carried by assault, temporized and opened negotiations for peace.

    183

    On the Columbia plateau the soil is principally volcanic ash and decomposed lava; it is almost wholly volcanic ash in the more arid sections, but elsewhere more decomposed lava or other igneous rocks, and some vegetable loam is mixed with the ash.

    184

    On the east the valley of the Kidron separates this plateau from the ridge of the Mount of Olives, which is 100 to 200 ft.

    185

    On the eastern flanks of the ranges the forest is much thinner, and on the interior plateau and in many of the valleys largely gives way to open grass land.

    186

    On the high plateau all attempts to grow cereals have failed, the wide trenches alone (Uda, Selenga, Jida) offering encouragement to the agriculturist.

    187

    On the highest parts of the plateau the climate is almost European, the nights being sometimes exceedingly cold.

    188

    On the hills the baobab and hyphaene palm are characteristic; on the plateau are stretches of open savanna, and park-like country with clumps of silk cotton and shea-butter trees.

    189

    On the lower plateau, in Transbaikalia, grain is successfully raised in the Nerchinsk region, with serious risks, however, from early frosts in the valleys.

    190

    On the lower terrace of the great plateau we find an 1 In Vega Exped.

    191

    On the margins of the plateau there are several gaps or indentations, which can best be likened to gigantic trenches, like railway cuttings, as with an insensible gradient they climb to a higher level.

    192

    On the New York side of the Hudson the rocks are crystalline, the surface a region of low hills, a continuation of the crystalline area of Connecticut, and comparable with the Piedmont plateau of the Southern states.

    193

    On the north the crag is crowned by a sort of plateau sloping backwards into a round-topped hill.

    194

    195

    On the north-east and east the plateau shelves gradually to the Euphrates and the Persian Gulf; only in the extreme east is this general easterly slope arrested by the lofty range of Jebel Akhdar, which from Ras Musandan to Ras el Had borders the coast of Oman.

    196

    On the other hand, the precipitation on the Tibetan plateau is so copious, and so uniformly distributed, that it is able to retain the loosened material in situ, and causes it to heap itself up in rounded masses on the flanks of the mountains that are its primitive source of origin, these projecting in great part like skeletons from the midst of their own ruins."

    197

    On the other hand, there are on the western outskirts of the plateau a few mountain chains which take a direction at right angles to the above (that is, from north-west to south-east), and parallel to the great line of upheavals in south-west Asia.

    198

    On the plateau many forms common elsewhere in East Africa, such as the Borassus palm and the baobab tree, are missing.

    199

    On the plateau of Tarnowitz the working and smelting of metals is the predominant industry, and in the neighbourhood of Beuthen, Konigshiitte and Gleiwitz there is an almost endless succession of iron-works, zincfoundries, machine-shops and the like.

    200

    On the plateau there are but few hills; the streams run slowly and the country is a mixture of plain and undulating ground covered by dense sdl forests.

    201

    On the plateau, which has an altitude of 4000 ft., there is good pasturage; inland the country slopes gently to a broad valley beyond which the view was bounded by the level horizon of the desert.

    202

    On the Pocono plateau is a large deposit of a finegrained dark-blue stone of the Devonian formation which is known as the Wyoming Valley stone, and, like the New York " bluestone," which it closely resembles, is much used for window and door trimmings, steps and flagging.

    203

    On the south of the plateau we find a similar succession of narrow valleys dividing parallel flexures, or anticlinals, formed under similar geological conditions to those which appear to be universally applicable to the Himalaya, the Hindu Kush, and the Indus frontier mountain systems. From one of these long lateral valleys the Hari Rud receives its principal tributary, which joins the main river below Obeh, 180 m.

    204

    On the Tibetan plateau, on the other hand, most of the ranges are distinguished by their rounded outlines and soft consistency, and their striking poverty in hard rock, which in the best cases only crops out near the summits.

    205

    On the whole, we may say that the arctic and boreal faunas of Europe extend over Siberia, with a few additional species in the Ural and Baraba region - a number of new species also appearing in East Siberia, some spreading along the high plateau and others along the lower plateau from the steppes of the Gobi.

    206

    One series of its numerous headstreams traverses the Kikuyu plateau north of the Athi, while others flow down the southern and eastern slopes of Kenya.

    207

    Outside the walls, over the sterile sand plateau, stretch great fields of tombs and graves, for Nejef is so holy that he who is buried here will surely enter paradise.

    208

    Palms are common, the chestnut abounds in many places, the cacti are almost as numerous as on the open plateau.

    216

    Profiting by the experience gained during the Athenian siege, he included in his new lines the whole plateau of Epipolae, with a strong fortress at Euryelus, its apex on the west; the total length of the outer lines (excluding the fortifications of the island) has been calculated at about 12 m.

    217

    Ranges of hills lead to the first plateau, which has an average elevation of 2000 ft.

    222

    Similarly Alexander found the Gates open, when he came down from the plateau in 333 B.C.; and from these facts it may be inferred that the great pass was not under direct Persian control, but under that of a vassal power always ready to turn against its suzerain.

    223

    Since this plateau region is a northward extension of the Alleghany plateau, which skirts the western base of the Appalachian mountains, it rises as the mountains are approached.

    234

    Taking their rise on the plateau formation, or in its outskirts, they flow first along lofty longitudinal valleys formerly filled with great lakes, next they cleave their way through the rocky barriers, and finally they enter the lowlands, where they become navigable, and, describing wide curves to avoid here and there the minor plateaus and hilly tracts, they bring into watercommunication with one another places thousands of miles apart.

    245

    The Archean protaxis is sometimes spoken of as a plateau, but probably half of it falls below 1000 ft.

    246

    The ascent to the upper plain then becomes very gentle, though there is a rise of 400 or 50o ft., until it reaches the south-eastern portion of Sargent county and changes into the more abrupt Coteau des Prairies, a plateau about 2000 ft.

    247

    The Aztecs from the 12th century appear to have migrated from place to place over the mountain-walled plateau of Anahuac, the country " by the water," so called from its salt lagoons, which is now known as the Valley of Mexico.

    The banken veld, formed by the denudation of the plateau, is much broken up and is rich in romantic scenery.

    249

    The border of this part of the plateau descends eastward by a single strong escarpment to the Hudson valley, from which the mountains present a fine appearance, and northward by two escarpments (the second being called the Helderberg Mountains) to the Mohawk Valley, north of which rise the Adirondacks; but to the south west the dissected highland continues into Pennsylvania and Virginia, where it is commonly known as the Alleghany plateau.

    The Hawiya domain comprises the Ogaden plateau and the region generally between the Nogal and Webi-Shebeli rivers.

    301

    The high plains of the west slope of the plateau are also rich prairies diversified with woods.

    302

    The highest part of this great plateau is to be found in the states of Mexico and Puebla, where the general elevation is about 8000 ft.

    303

    The Highland Rim Plateau, lying to the south, east and west of the escarpment, embraces fully one-half of the state, slopes from elevations of1000-1200ft.

    304

    The hills in the south of the duchy are a continuation of the Lorraine plateau, and the northern districts are crossed in all directions by outrunners from the Ardennes.

    305

    The Hindu Kush represents the southern edge of a great central upheaval or plateau.

    306

    The horizontal strata of the plateau present equal ease or difficulty of erosion in any direction; the streams and the submature valleys of the plateau therefore ramify in every direction, thus presenting a pattern that has been called insequent, because it follows no apparent control.

    307

    The hydrography of Mexico, therefore, is of the simplest description - a number of small streams flowing from the plateau or mountain slopes eastward to the Gulf of Mexico and westward to the Pacific. Most of these are little more than mountain torrents, but one has a course exceeding 500 m., and few have navigable channels.

    308

    The Indian-corn, wheat and livestock sections of the state, are in the Piedmont Plateau, the Hagerstown Valley and the central portion of the East Shore.

    309

    The inhabitants of Baden are of various origin - those to the north of the Murg being descended from the Alemanni and those to the south from the Franks, while the Swabian plateau derives its name and its population from another race.

    310

    The interior plateau may be described as arid, so that irrigation is required if crops are to be raised.

    311

    The jaguar and puma have found their way into the United States, while the wolf, coyote, bear and beaver have gone far southward on the plateau, and the buffalo was once found in large numbers on its more favoured northern plains.

    312

    The Kerguelen plateau rises in many parts to within 1500 fathoms of the surface of the sea.

    313

    The Kobdo river, which rises in the Dain-gol (7060 ft.) in the Ektagh Altai, winds in great curves across the plateau, and enters Lake Kara-usu (3840 ft.), which also receives the Buyantu, an outflow from Lake Kobdo, and is connected by a small river with another large lake, Durga-nor, situated a score of miles to the east.

    314

    The largest streams are the Rovuma and Rufiji (q.v.), both rising in the central plateau and flowing to the Indian Ocean.

    315

    The last serious attempt of the allies in the centre led to some of the hardest fighting of the day; the Russian Imperial Guard under the grand-duke Constantine pressed closely upon St Hilaire and Vandamme on the plateau, and only gave way when the French Guard and the Grenadiers came into action.

    316

    The latter almost at once encountered the heads of the 6th cavalry division, at that moment just clearing the defile leading up to the Rezonville plateau from Gorze.

    317

    The latter descend from the plateau much nearer the coast, and are in most cases navigable for short distances only.

    318

    The latter with at least 50,000 men was marching in two columns, and ought therefore to have delivered its men into line of battle twice as fast as the French, who had to deploy from a single issue, and whose columns had opened out in the passage of the Kosen defile and the long ascent of the plateau above.

    319

    The long straight lines of works which stretched to the plateau of the Michelsberg and formed the outworks of the main fortress on the left bank of the Danube were purchased in 1900 by the municipal authorities, in order to be levelled and laid out in streets for the extension of the town in this direction.

    320

    The longest and most prominent of these ranges, which are for the most part the eastern escarpments of the great Brazilian plateau, is the Serra dos Aymores, which extends along fully two-thirds of the western frontier.

    321

    The main body were between Weimar and Apolda during the 12th, and the Saxons duly effected their junction with Hohenlohe in the vicinity of Vierzehnheiligen, whilst the latter had withdrawn his troops all but some outposts from Jena to the plateau about Capellendorf, some 4 m.

    322

    The main watershed follows a tortuous course which crosses the mountainous belt just north of New river in Virginia; south of this the rivers head in the Blue Ridge, cross the higher Unakas, receive important tributaries from the Great Valley, and traversing the Cumberland Plateau in spreading gorges, escape by way of the Cumberland and Tennessee rivers to the Ohio and Mississippi, and thus to the Gulf of Mexico; in the central section the rivers, rising in or beyond the Valley Ridges, flow through great gorges (water gaps) to the Great Valley, and by southeasterly courses across the Blue Ridge to tidal estuaries penetrating the coastal plain; in the northern section the water-parting lies on the inland side of the mountainous belt, the main lines of drainage running from north to south.

    323

    The Maryland building stone, of which there is an abundance of good quality, consists chiefly of granites, limestones, slate, marble and sandstones, the greater part of which is quarried in the east section of the Piedmont Plateau especially in Cecil county, though some limestones, including those from which hydraulic cement is manufactured, and some sandstones are obtained from the western part of the Piedmont Plateau and the east section of the Appalachian region; the value of stone quarried in the state in 1907 was $1,439,355, of which $1,183,753 was the value of granite, $142,825 that of limestone, $98,918 that of marble, and $13,859 that of sandstone.

    324

    The mean annual temperature decreases to the north-westward on the Alleghany plateau, but on the Erie plain, in the extreme north-west, Lake Erie exerts its moderating influence, the mean temperature rises, and extremes shorten.

    325

    The Mistecas, or Mixtecas, and Zapotecas, who occupy the southern slopes of the central plateau, especially Puebla, Morelos, Oaxaca and Guerrero, form another distinct race, whose traditional history goes back to the period when the structures now known as Mitla, Monte Alban, Xochicalco and Zaachila were built.

    326

    The Mongols (less than 300,000) extend into West Siberia from the high plateau - nearly 20,000 Kalmucks living in the eastern Altai.

    327

    The more important of the suburbs lie towards the east, where the promontory joins the main plateau, of which it forms the north-western extremity.

    328

    The most common plants of the Mexican plateau are the agaves, yuccas and cacti, each of which is represented by a number of species.

    329

    The most favourable regions are those of the tierras ternpladas, especially on the southern slopes of the great central plateau which were thickly populated in prehistoric times.

    330

    The most important buildings of which we have any remains are to be found in the lower part of Achradina and in Neapolis, a quarter of which we hear first in the time of Dionysius, and which at first was confined to the lower ground below Temenites, but in Roman times included it and the theatre also (Lupus 168), though it did not extend beyond the theatre to the uppermost part of the plateau.

    331

    The most important line of cliffs of this class is associated with the western and southern boundary of the plateau province, where it was uplifted from the lower ground.

    332

    The mountain chain, too, is less distinctly marked, and becomes little more than the seaward escarpment of the plateau which intervenes between the coast and the Hadramut valley.

    333

    The native population of the plateau of Mexico, mainly Aztecs, may still be seen by thousands without any trace of mixture of European blood.

    334

    The navigable channels of these rivers are restricted to the coastal plain, except where a river has excavated for itself a valley back into the plateau.

    335

    The next important line is the F.C. Internacional Mexicano, running from Ciudad Porfirio Diaz, on the Rio Grande, south-westward across the plateau to Durango, and is to be extended to Mazatlan, on the Pacific coast.

    336

    The next succeeding parallel range, the Koko-shili, which is continued eastwards by the Bayan-khara-ula, between the upper headstreams of the Hwang-ho or Yellow River and the Yangtszekiang, belongs orographically to the plateau of Tibet.

    337

    The northern and western parts of this plateau have an average elevation a little less than that of the Atlantic margin, and their slopes are toward the south and east, those of Goyaz and Matto Grosso being abrupt and deeply eroded.

    338

    The northern edge of the plateau follows an irregular line from somewhat north of Mafeking on the west to the Mauchberg on the east.

    339

    The northern part can best be regarded as a low plateau (once marine sediments) sloping southward, traversed by the large diluvial valleys of the Mississippi, Red and Ouachita rivers, and recut by smaller tributaries into smaller plateaus and rather uniform flat-topped hills.

    340

    The northern section includes the Shickshock Mountains and Notre Dame Range in Quebec, scattered elevations in Maine, the White Mountains and the Green Mountains; the central comprises, besides various minor groups, the Valley Ridges between the Front of the Allegheny Plateau and the Great Appalachian Valley, the New York-New Jersey Highlands and a large portion of the Blue Ridge; and the southern consists of the prolongation of the Blue Ridge, the Unaka Range, and the Valley Ridges adjoining the Cumberland Plateau, with some lesser ranges.

    341

    The northern slope of this great plateau is drained by the AraguayaTocantins, Xingu, Tapajos and Guapore-Mamore-Madeira, which flow northward, and, except the first, empty into the Amazon; the southern slope drains southward through a multitude of streams flowing into the Parana and Paraguay.

    342

    The oldest rocks, the gneisses and schists of the Archean period, form nearly the whole of the Central Plateau, and are also exposed in the axes of the folds in Brittany.

    343

    The Orange here enters the great inner plateau of South Africa, which at Aliwal North, the first town of any size on the banks of the river, 80 m.

    344

    The orography of the Aldan region is little known; but travellers who journey from the Aldan (tributary of the Lena) to the Amur or to the Sea of Okhotsk have to cross the same plateau and its border-range.

    345

    The other principal river, the Aisne, crosses the southern border and takes a northerly, then a westerly course, separating the region known as Champagne Pouilleuse from the more elevated plateau of Argonne which forms the central zone of the department and stretches to the left bank of the Meuse.

    346

    The Otomis comprise a large number of tribes occupying the plateau north of the Anahuac sierras.

    347

    The overthrust came from the south-east, and the Palaeozoic beds were crushed and crumpled against the ancient massif of the central plateau.

    348

    The Paropamisus forms the southern face of the Turkestan plateau, which contains the sources of the Murghab river; the northern face of the same plateau is defined by the Band-i-Turkestan.

    349

    The part of Maryland within the Piedmont Plateau extends west from the Fall Line to the base of Catoctin Mountain, or the west border of Frederick county, and has an area of about 2500 sq.

    350

    The Pennsylvania portion of the younger Appalachian ridges and valleys, known as the central province of the state, embraces the region between the South Mountains, on the south-east, and the crest of the Alleghany plateau or Alleghany Front, on the north-west.

    351

    The picturesque Bureya Mountains above the Amur, the forest-clad Sikhota-alin on the Pacific, and the volcanic chains of Kamchatka belong, however, to quite another orographical construction, being the border-ridges of the terraces by which the great plateau formation descends to the depths of the Pacific Ocean.

    352

    The Piedmont Plateau Region extends from this line to the Blue Ridge Escarpment, toward which its mean elevation increases at the rate of about 32 ft.

    353

    The plains inland from Berbera, and the maritime margins between the coast and foot of the plateau, consist of limestones of Lower Oolitic age with Belemnites subhastatus.

    354

    The plateau "lowlands" in the centre of the Basin are approximately 5000 ft.

    355

    The plateau at its foot was the site of the English laager during the war of 1880-81, and is now occupied by the central railway station and workshops.

    356

    The plateau breaks down abruptly toward the sea, and slopes gradually some hundreds of feet toward the south and west.

    357

    The plateau is built up of granites, gneisses and crystalline schists of Archean and probably Primary age.

    358

    The plateau is partly grass land without bush and forest, partly steppe covered with mimosa bush, which sometimes is almost impenetrable.

    359

    The plateau of Odenpah, drained by tributaries of the Embach river, which flows for 93 m.

    360

    The Plateau province, next west of the southern Rocky Mountains, is characterized for the most part by large-textured forms, developed on a great thickness of nearly horizontal Palaeozoic, The Plateau Mesozoic and Tertiary formations, and by a dry climate.

    361

    The plateau was too small for it to land, but it hovered near the edge.

    362

    The plateau, known as the Ogaden plateau, everywhere presents the same monotonous aspect of a boundless steppe clothed with a scanty vegetation of scrubby plants and herbaceous growths.

    363

    The Pocono plateau, into which the central province merges at its north-east extremity, is a continuation of the Catskill plateau southward from New York and covers Wayne, Pike and Monroe counties and the east portion of Carbon county.

    364

    The portion of Asia west of British India, excluding Arabia and Syria, forms another extensive plateau covering an area as large as that of Tibet, though at a much lower altitude.

    365

    The precipitation varies widely, that of the western side of the northern plateau (Chihuahua and Durango) being about 39 in., that of the Valley of Mexico about 25 in., and that of the whole republic 59 in.

    366

    The principal exception is the Zatas or Sorraia, which, rising in the Serra d'Ossa, flows westwards across the plateau of Alemtejo, and joins the Mar de Pedro.

    367

    The pulque industry is located on the plateau surrounding the city of Mexico, the most productive district being the high, sandy, arid plain of Apam, in the state of Hidalgo, where the " maguey " (A gave americana) finds favourable conditions for its growth - a dry calcareous surface with moisture sufficiently near to be reached by its roots.

    368

    The rainfall in the low country is more erratic than on the plateau, and in some districts, a whole year will pass without rain.

    369

    The rainfall is heaviest along the western fringe of the plateau, and penetrates inland in decreasing quantity over a zone which perhaps extends to loo m.

    370

    The rainfall throughout this region is abundant, except in northern Minas Geraes, where the climatic conditions are influenced to some extent by the arid eastern plateau.

    371

    The region between the lines of the two coastal systems is a much dissected plateau, imperfectly explored.

    372

    The remainder of the state which lies east of the Tennessee river is divided into the Highland Rim Plateau and a lowland basin, eroded in the Highland Rim Plateau and known as the Blue Grass Region; this region is separated from the Highland Rim Plateau by a semicircular escarpment extending from Portsmouth, Ohio, at the mouth of the Scioto river, to the mouth of the Salt river below Louisville; it is bounded north by the Ohio river.

    373

    The Reventazon, or Parismina, flows from the central plateau to the Caribbean Sea; despite the shortness of its valley, its volume is considerable, owing to the prevalence of moist trade-winds near its sources.

    374

    The Rio Grande de Tarcoles rises close to the Ochomogo Pass and the sources of the Reventazon, at the base of Irazu; and the headwaters of these two streams indicate precisely the depression in the central plateau which severs the northern from the southern mountains.

    375

    The rivers of the state include a number of small plateau streams flowing southward to the Sao Francisco River, and several large streams in the eastern part flowing eastward to the Atlantic. The former are the Moxoto, Ema, Pajehu, Terra Nova, Brigida, Boa Vista and Pontai, and are dry channels the greater part of the year.

    376

    The rivers which most perfectly exemplify this habit are the Delaware, Susquehanna and Potomac; the Hudson, the north-eastern boundary of the middle section, is peculiar in having headwaters in the Adirondacks as well as in the Catskills (northern part of the plateau); the James, forming the south-western boundary of the section, rises in the inner valleys of the stratified belt, instead of in the plateau.

    377

    The round flattened summits of the Valdai plateau do not rise above 1100 ft., and they present the appearance of mountains only in consequence of the depths of the valleys - the rivers which flow towards the depression of Lake Peipus being only 200 to 250 ft.

    378

    The Russians in Sokolnitz surrendered, an opportune cavalry charge further discomfited the allied left, and the Pratzen plateau was now in full possession of the French.

    379

    The same idea had, however, occurred to Ladmirault, and he had called on the two nearest French cavalry divisions to put it into execution, and as the Prussians began to reach the plateau west of Mars-la-Tour and the Yron brook from the south, the French were deploying across it some two thousand yards to the north.

    380

    The same Paiaeozoic formations that are folded in the belt of the Alleghany ridges lie nearly horizontal in the plateau district next north-west.

    381

    The Sao Francisco, which belongs to the inland plateau region, is the largest river of the eastern coast of Brazil and exists by virtue of climatic conditions wholly different from those of the coast where it enters the Atlantic. The tributaries of the lower half of this great river, which belong to the Atlantic coast region, are small and often dry, but the upper river where the rainfall is heavier and more regular receives several large affluents.

    382

    The scene of the most important fighting was the Pratzen plateau.

    383

    The sea does not appear to have extended completely across Australia, breaking it into halves, for a projection from the Archean plateau of Western Australia extended as far east as the South Australian highlands, and thence probably continued eastward, till it joined the Victorian highlands.

    384

    The second and marine type of the Jurassics occurs in Western Australia, on the coastal plain skirting the western foot of the western plateau.

    385

    The second plateau, reached by a steep ascent, has an elevation of from nearly 4000 to fully 5000 ft.

    386

    The Secondary and Tertiary beds of the Languedoc were crushed against the central plateau and were frequently overfolded.

    387

    The shore consists of a central plateau descending to the water in three terraces, each with its "tread" and "rise."

    388

    The Siberian larch predominates also in the alpine tracts fringing the plateau on the north, intermingled with the fir, stone-pine, aspen and birch.

    389

    The Sicilian-Ionian basin has a mean depth of 885 fathoms, and the Levant basin, 793 fathoms. Deep water is found close up to the coast of Sicily, Greece, Crete and the edge of the African plateau.

    390

    The Sierra Madre crosses the southern part of the state parallel with the coast, separating the low, humid, forested districts on the frontier of Tabasco from the hot, drier, coastal plain on the Pacific. The mountain region includes a plateau of great fertility and temperate climate, which is one of the best parts of Mexico and contains the larger part of the population of the state.

    391

    The Sierra Madre Oriental consists of a broken chain of ranges extending along the eastern margin of the plateau from the great bend in the Rio Grande south-eastward to about the 19th parallel.

    392

    The slopes of the plateau which face the rain-bringing monsoon are in some places covered with primeval forest, in which timber is plentiful.

    393

    The slopes of the plateau, which receive a better rainfall, are more heavily forested, some districts being covered with deciduous trees, forming catingas in local parlance.

    394

    The soils of the Piedmont Plateau east of Parr's Ridge are, like the underlying rocks, exceptionally variable in composition, texture and colour.

    395

    The south-east part of the province, to the east of the Oder and south of the Malapane, consists of a hilly outpost of the Carpathians, the Tarnowitz plateau, with a mean elevation of about woo ft.

    396

    The south-eastern slope of the great plateau of Asia cannot properly be reckoned to Siberia, although parts of the province of Amur and the Maritime Province are situated on it; - they have quite a different character, climate and vege- eastern, tation, and ought properly to be reckoned to the Manslope of, churian region.

    397

    The southern portion of the land forms a plateau which slopes to Mt.

    398

    The southern terraces of the plateau have no high mountain barriers between them and the moist winds of the Caribbean, and they too receive an abundant rainfall in the wet season, especially during the prevalence of heavy " northers " on the Gulf coast.

    399

    The species of fauna that are at all characteristic of this part of the United States are found in the Piedmont Plateau Region and the western portion of the Coastal Plain Region.

    400

    The St Lawrence system receives the most, mainly from short streams from the plateau province and from the Adirondacks.

    401

    The state belongs to the elevated plateau region, with its semi-arid conditions.

    402

    The state may be naturally divided into plain, plateau and hilly country.

    403

    The state occupies an elevated plateau, extending from two spurs of the Sierra Madre, called the Sierra Fria and Sierra de Laurel, eastward to the rolling fertile plains of its eastern and south-eastern districts.

    404

    The steeply rising face of the plateau here is due to the resistance of a durable layer of limestone, known as the Helderberg limestone.

    405

    The streams flowing from the central area have cut deep gorges and canons, and among the ridges the granitic rocks have assumed many strange forms. Though rising from a semi-arid plateau, these mountains have sufficient rainfall to support an abundant plant growth, and have derived their name from the fact that their slopes are dark with heavy forests.

    406

    The submature or mature dissection of the plateau by its branching insequent streams results in giving it an excess of sloping surface, usually too steep for farming, and hence left for tree growth.

    407

    The succession of ranges which follow one another from the deserts of Takla-makan and Gobi up to the plateau proper of Tibet rise in steps or terraces, each range being higher than the range to the north of it and lower than the range to the south of it.

    408

    The surface features consist of an immense elevated plateau with a chain of mountains on its eastern and western margins, which extends from the United States frontier southward to the Isthmus of Tehuantepec; a fringe of lowlands (tierras calientes) between the plateau and coast on either side; a detached, roughly mountainous section in the south-east, which belongs to the Central American Plateau, and a low sandy plain covering the greater part of the Isthmus of Yucatan.

    409

    The surface of the plateau is generally open campo and scrubby arboreal growth called caatingas, but the streams are generally bordered with forest, especially in the deeper valleys.

    410

    The table-topped hills of Almeyrin (or Almeirim) and Erere, which lie near the lower Amazon and rise to heights of 800 and 900 ft., are generally considered the southernmost margin of this plateau, though Agassiz and others describe them as remains of a great sandstone sheet which once covered the entire Amazon valley.

    411

    The Tatar zodiac is not unfrequently found engraven on Chinese mirrors in polished bronze or steel of the 7th century, and figured on the " plateau of the twelve hours "' 5 " Orat.

    412

    The third part is the north, which belongs to the central plateau, still much higher, and therefore rough and very cold in the winter.

    413

    The three principal rivers - the Ob, the Yenisei, and the Lena - take their rise on the high plateau or in the alpine regions fringing it, and, after descending from the plateau and piercing the alpine regions, flow for many hundreds of miles across the high plains and lowlands before they reach the Arctic, Ocean.

    414

    The Totonacs inhabit northern Vera Cruz and speak a language related to that of the Mayas; the Tarascos form a small group living in Michoacan; the Matlanzingos, or Matlaltzincas, live near the Tarascos, the savage Apaches, a nomadic group of tribes ranging from Durango northward into the United States; the Opata-Pima group, inhabiting the western plateau region from Sonora and Chihuahua south to Guadalajara, is sometimes classed as a branch of the Nahuatlaca; the Seris, a very small family of savages, occupy Tiburon Island and the adjacent mainland of Sonora; and the Guaicuros, or Yumas, are to be found in the northern part of the peninsula of Lower California.

    415

    The town is charmingly situated on a small plateau, 1680 ft.

    416

    The transition from the strongly folded structure of the Alleghany ridges and valleys to the nearly horizontal structure of the Appala; chian plateau is promptly made; and with the change of structure comes an appropriate change of form.

    417

    The tributaries of the Amur (the Shilka with its affluent the Ingoda) become navigable only on the lower terrace of the plateau.

    418

    The Tunguses (nearly 70,000) occupy as their hunting-grounds an immense region on the high plateau and its slopes to the Amur, but their limits are yearly becoming more and more circumscribed both by Russian gold-diggers and by Yakut settlers.

    419

    The unity and continuity of the district, expressed in the name Appalachian plateau, is seldom recognized in local usage.

    420

    The upper plateau (Achradina, Tyche, Epipolae itself) is now largely cultivated at the east end, less so at the west end.

    421

    The Vistula, here of great width, and subject to destructive floods, enters the province near Thorn, and flowing north in a valley which divides the plateau, enters Danzig Bay by a large delta, the Werder.

    422

    The volcanic plateau of British East Africa extends over the boundary in the region of Kilimanjaro.

    423

    The Wami and Kingani, smaller streams, have their origin in the mountainous region fringing the central plateau, and reach the ocean opposite the island of Zanzibar.

    424

    The western escarpment of the plateau rises steeply from the Red Sea littoral to a height of from 4000 to 8000 ft., leaving a narrow belt of lowland rarely exceeding 30 m.

    425

    The western part of the range, which received the name of Paropamisus Mons from the ancients, diminishes in height west of the 65th meridian and constitutes the northern face of the Afghan and Persian plateau, rising abruptly from the plains of the Turkoman desert, which lies between the Oxus and the Caspian.

    426

    The whole Basin is marked by three features of elevation - the Utah basin, the Nevada basin and, between them, the Nevada plateau.

    427

    The whole region is characterized by a remarkable degree of physical uniformity, and may be broadly described as a vast plateau of an average elevation of 3000 ft., bounded westwards by the Ethiopian and Galla highlands and northwards by an inner and an outer coast range, skirting the south side of the Gulf of Aden in its entire length from the Harrar uplands to Cape Guardafui.

    428

    The wild seringa (Burkea africana) is also characteristic of the low veld and, extends up the slopes of the plateau.

    429

    The windward slopes of the Sierra Madre Oriental receive the greater part of the rainfall, and the winds, deprived of their moisture, pass over the northern plateau without further precipitation.

    430

    The, 6th century saw the establishment of a powerful Gond kingdom by Sangram Sah, who succeeded in 1480 as the 47th of the petty Gond rajas of Garha-Mandla, and extended his dominions so as to include Saugor and Damoh on the Vindhyan plateau, Jubbulpore and Narsinghpur in the Nerbudda valley, and Seoni on the Satpura highlands.

    431

    Then come the catinga tracts, and, beyond these, the open campos of the elevated plateau, dotted with clumps of low growing bushes and broken by tracts of carrasco, a thick, matted, bushy growth 10 to 12 ft.

    432

    Thence four marches, generally over a stony plateau dominated by bare, sterile mountains, brought them to Sana, where they received a cordial welcome from the imam, el Mandi Abbas.

    433

    Thence issue many streams which in their way to the ocean have forced their way through the ranges of hills which mark the steps in the plateau, forming the narrow passes or poorts characteristic of South African scenery.

    434

    There are also a few of greater length which rise far back on the plateau itself and flow down to the plain through deeply cut, precipitous courses.

    435

    There are also indications of another series of faults roughly parallel to the south-east coast, which point to the islands being fragments of a former extensive plateau.

    436

    There are also several alkali lakes or chains of alkali lakes in the coulees on the Columbia plateau.

    437

    There are many forests which clothe the slopes of the plateau.

    438

    There are other lower escarpments in the plateau province, similar in form and cause to the Helderberg escarpment.

    439

    There are wide areas on the plains of West Siberia and on the high plateau of East Siberia, which, virtually, are still passing through the Lacustrine period; but the total area now under water bears but a trifling proportion to the vast surface .which the lakes covered even at a very recent period, when Neolithic man inhabited Siberia.

    440

    There are, however, among these border-ranges several breaches of continuity - broad depressions or trenches leading from Lake Balkash and Lake Zaisan to the upper parts of the plateau.

    441

    There is no absolutely dry season in this part of the great Brazilian plateau, though the year is customarily divided into a dry and wet season, the latter running from September to April in Goyaz, and from November to April in Matto Grosso.

    442

    Thereafter it broadens out and becomes the high table-land of Galilee, Samaria and Judaea, and gradually sinks into the plateau of north Sinai.

    443

    These drawbacks tend to restrict agriculture on the plateau to comparatively limited areas, and the country people are, in general, extremely poor and badly nourished.

    444

    These mountains, which have in the northern part an altitude of 2700 ft., slope down towards the south-east near Tokaj in a hilly plateau of about 1500 ft.

    445

    These railway communications, and the situation of the city (on the Piedmont Plateau) on the water-parting between the streams flowing into the Atlantic Ocean and those flowing into the Gulf of Mexico, have given Atlanta its popular name, the "Gate City of the South."

    446

    These sierras lying near the coast have an imposing appearance from the lowlands, but when seen from the plateau their general elevation is so dwarfed as to render them comparatively inconspicuous.

    447

    These trenches have for successive geological periods been the drainage valleys of immense lakes (probably also of glaciers) which formerly extended over the plateau or fiords of the seas which surrounded it.

    448

    These winds are charged with moisture, which they part with on ascending the precipitous side of the plateau.

    449

    They are also preserved in basins on the western plateau, as shown by brown coal deposits passed through in the Lake Phillipson bore.

    450

    They comprise the geographically distinct regions of the Anatolian plateau (Asia Minor), the Armenian and Kurdish highlands, the Mesopotamian lowlands, the hilly and partly mountainous territory of Syria and Palestine and the coast lands of west and north-east Arabia.

    451

    They did not, however, occupy Euryelus, at the western extremity of the high ground of Epipolae, and this omission allowed the Athenians to obtain possession of the whole plateau, and to begin the investment of the city.

    452

    They form the greater part of the Sierra Madre Oriental and also cover most of the central plateau.

    453

    They had been preceded on the same plateau by the Chichimecs, possibly of the same race, who were conquered by the Aztecs sometime in the 15th century after a supposed occupation of the territory about 400 years.

    454

    They inhabit the western Sierra Madre region from Sinaloa southward to Chiapas, the higher plateau states, which region was the centre of their empire when Cortes conquered them, and parts of Vera Cruz, Tabasco, Oaxaca, Morelos, Aguascalientes and San Luis Potosi.

    455

    They may be divided into two classes; those of the plateau region which occupy lacustrine depressions and receive the drainage of the surrounding country; and the tide-water lagoons of the coast formed by the building up of new sand beaches across the indentations in the coast-line.

    456

    They occur, however, along the coasts, where they are marine, and also on the central plateau, where they are of lacustrine origin.

    457

    They then form part of a system of ranges which curve north of the sources of the Chindwin river, and with the Kumon range and the hills of the Jade and Amber mines, make up a highland tract separated from the great Northern Shan plateau by the gorges of the Irrawaddy river.

    458

    This arises chiefly from the orographical structure; the vast plateau of Central Asia prevents the moderating influence of the sea from being felt.

    459

    This bank continues southwards to the Antarctic Ocean, expanding into a plateau on which Australia stands, and a branch runs eastwards and then southwards from the north-east of Australia through New Zealand.

    460

    This conformation is seen in the valley of the Us in West Sayan, in that of the upper Oka and Irkut in East Sayan, in the valley of the Barguzin, the upper Tsipa, the Muya and the Chara, at the foot of the Vitim plateau, as also, probably, in the Aldan.

    461

    This great plateau, extending from the Mediterranean to the Indus, has a length of about 2500 m.

    462

    This may be either the Atlantic or the Gulf of Bothnia, according as the migration has commenced from the west or the east side of the central elevated plateau.

    463

    This ocean, already diminished in area, retreated after Oligocene times from the Iranian plateau, Turkestan, Asia Minor and the region of the north-west Alps.

    464

    This plateau belt is exceedingly rugged with sharp ridges alternating with narrow valleys which have steep sides but are seldom more than 150o ft.

    465

    This plateau province, which includes more than half the state, differs greatly from place to place.

    466

    This plateau region is watered by numerous tributaries of the Parnahyba, chief of which are the Urussuhy, the Caninde and its tributary the Piauhy, the Gurgueia and its tributary the Parahim, which drains the large inland lake of Parnagua, the Longa, and the Poty, which has its source in the state of Ceara.

    467

    This plateau, however, is not a plain, but contains many buttes and mesas and isolated mountain ranges rising from 1000 to 8000 ft.

    468

    This range forms the true backbone of the maritime mountainous belt and rises from the plateau itself, while the Coast Range rises on its eastern margin and forms a rim to the plateau.

    469

    This region is the smallest of the chapadao divisions of the great plateau, and might be considered either a southward extension of the Sao Francisco or an eastward extension of the Parana chapadao.

    470

    This region is well wooded along the river courses of Minas Geraes, the lower Atlantic slopes of Bahia, which are perhaps outside the plateau proper, and on the weather side of some of the elevated ridges where the rainfall is heavy and regular.

    471

    This river system drains a large part of the northern mountainous region of the state, and has a considerable extension of navigable channels between the plateau margin and the lake.

    472

    This uncertainty in the wheat crop extends to the southern limits of the higher plateau, and is a serious obstacle to the increased production of this cereal.

    473

    Those of the northern plateau are small, hardy and long-lived, being bred on extensive ranges in a cooler atmosphere, and accustomed to long journeys in search of water and pasture.

    474

    Though the plateau region was settled soon after the arrival of the Spaniards in Mexico, there are large districts on the southern and Pacific slopes that still belong almost exclusively to the Indians.

    475

    Though the Uruguay plays a less important part, its relations to the country are similar to those of the Parana, and its tributaries from the plateau region are similarly broken by falls and rapids.

    476

    Though, thanks to the overlaying porous pumice, the Taupo plateau is not fertile, it has a good rainfall and is drained by unfailing rivers running through deep terraced ravines.

    477

    Throughout much of the Piedmont Plateau and Mountain regions the decomposition of felspar and of other aluminous minerals has resulted in a deep soil of clay with which more or less sand is mixed.

    478

    Thus it consists of the immense plains and flat lands which extend between the plateau formation and the Arctic Ocean, including the series of parallel chains and hilly spurs which skirt the former region on the N.W.

    479

    Thus the Ektagh Altai is a true border-rangethat is, a lofty and steep escarpment facing the Dzungarian depression, with a gentle and relatively short slope towards the plateau.

    480

    To the eastward it abounds in mountains and valleys; to the westward it is a rolling plateau.

    481

    To the north the plateau gradually slopes away towards the Oxus,, falling from an average altitude of 15,000 ft.

    482

    To the south lies a rolling plateau of basaltic formation (with the sacred town of Multai, and the springs of the river Tapti at its highest point), extending over the whole of the southern face of the district, and finally merging into the wild and broken line of the Ghats, which lead down to the plains.

    483

    To the south of the Usambara hills, and on the eastern edge of the plateau, are the mountainous regions of Nguru (otherwise Unguru), Useguha and Usagara.

    484

    To the south of this variegated region lies a desert plateau, 2000 ft.

    485

    Two such folds maybe distinguished, corresponding on a smaller scale to the belt of alpine tracts which fringe the plateau on the north-west.

    486

    Two volcanic Cordilleras or mountain chains, separated from one another by the central plateau of San Jose and Cartago, traverse the interior of Costa Rica, and form a single watershed, often precipitous on its Pacific slope, but descending more gradually towards the Atlantic, where there is a broad expanse of plain in the north-east.

    487

    Under Turkish protection, he visited the territory of the Hashid and Bakil tribes north-east of Sana, and though their hostile attitude compelled him to return after reaching their first important town, Khamr, he had time to reconnoitre the plateau lying between the two great wadis Kharid and Hirran, formerly covered with Himyaritic towns and villages; and to trace the course of these wadis to their junction at El Ish in the Dhu Husen country, and thence onward to the Jauf.

    488

    Up to the year 1862 not only was the fortress of Belgrade garrisoned by Turkish troops, but the Danubian slope of the town was inhabited by Turks, living under a special Turkish administration, while the modern part of the town (the plateau of the ridge and the western slope) was inhabited by Servians living under their own authorities.

    489

    Upon this limestone plateau there is a central area of high ridges, among them the rough crags of Harney, Custer and Dodge peaks.

    490

    Ustun-tagh, which appears on Stieler's map as an alternative name for Altyn-tagh, means Higher or Farther Mountains, and though not used locally of any specific range, would be appropriately employed to designate the higher and more southerly of the twin border-ranges of the Tibetan plateau.

    491

    Valleys are deeply sunk in the plateau, the largest with bottom lands of sufficient width to give rise to strips of fertile farm land.

    492

    Volcanic features occur in abundance in the Plateau province.

    493

    Volcanic formations, so far as is known, occur chiefly along the north-western border-range of the great plateau.

    494

    West and north of the Drakensberg the general level of the low veld is not much below that of the lowest altitudes of the middle veld, though the climatic 1 By the Boers the western and less elevated part of the plateau is known as the middle veld.

    495

    West of Ararat high hills extend along the Black Sea, between which and the Taurus range lies the plateau of Asia Minor, reaching to the Aegean Sea; the mountains along the Black Sea, on which are the Olympus and Ida of the ancients, rise to 6000 or 7000 ft.; the Taurus is more lofty, reaching 8000 and 10,000 ft.; both ranges decline in altitude as they approach the Mediterranean.

    496

    When any combination of circumstances has occasioned an increase of the numbers of the lemmings in their ordinary dwelling-places, impelled by the restless or migratory instinct possessed in a less developed degree by so many of their congeners, a movement takes place at the edge of the elevated plateau, and a migration towards the lower-lying land begins.

    497

    When the first Moteuczoma was crowned king of the Aztecs, the Mexican sway extended far beyond the valley plateau of its origin, and the gods of conquered nations around had their shrines set up in Tenochtitlan in manifest inferiority to the temple of Huitzilopochtli, the war-god of the Aztec conquerors.

    498

    When the two lowlands are traced eastward they become confluent after the Niagara limestone has faded away in central New York, and the single lowland is continued under the name of Mohawk Valley, an east-west longitudinal depression that has been eroded on a belt of relatively weak strata between the resistant crystalline rocks of the Adirondacks on the north and the northern escarpment of the Appalachian plateau (Catskills-Helderbergs) on the south; forming a pathway of great historic and economic importance between the Atlantic seaports and the interior.

    499

    With the exception of the extreme north (Commagene), which is shut off by a barrier of hills and belongs to foreign hydrographic systems, the whole country is roughly a gable-shaped plateau, falling north and south from a medial ridge, which crosses Syria at about its central point.

    500

    Without pausing to fire, the men raced onward, but the French striking their outer wing rolled up the whole line in succession, the actual collision occurring in and near the Bruville ravine, a deep-cut natural trench which, starting from the Tronville copses, here intersects the plateau from west to east.
