Since 1884 the Italian Government have been systematically enclosing, pumping dry, and generally draining the marshes of the Agro Romano, that is, the tracts around Ostia; the Isola Sacra, at the mouth of the Tiber; and Maccarese.
The wheat crop in 1906 in the Agro Romano was 8,108, 500 bushels, the Indian corn 3,314,000 bushels, the wine 12,100,000.
