According to the "Encyclopædia Britannica" Eleventh Edition, in 1910 over 1,000 km2 (400 mile2) of the Faiyum Oasis was cultivated, the chief crops being cereals and cotton. The completion of the Aswan Low Dam ensured a fuller supply of water, which enabled 20,000 acres (80 km2) of land, previously unirrigated and untaxed, to be brought under cultivation in the three years 1903-1905. Three crops were obtained in twenty months. The province was noted for its figs and grapes of exceptional quality. Olives were also cultivated. Rose trees were very numerous, and most of the attar of roses of Egypt was manufactured in the province. Faiyum also possessed an excellent breed of sheep.
