The completion of the Assuan dam by ensuring a fuller supply of water enabled 20,000 acres of land, previously unirrigated and untaxed, to be brought under cultivation in the three years 1903-1905.
The brewing of beer from rice and other grains, which is universal among the hill tribes and other aboriginal races, is practically untaxed and unrestrained.
In 1890 there were in the state 2893 untaxed and 3538 taxed Indians, the latter being citizens; in 1900 there were 3,322 altogether, all of them taxed; and in 1908 there were 3720, of whom 1270 were Omaha, 1116 Santee Sioux, 1060 Winnebago and 274 Ponca.
