Antonio de Espejo
In February 1583, Espejo arrived at the territory of the Piros, the most southerly of the Pueblo villagers. From there the Spanish continued up the Rio Grande. Espejo described the Pueblo villages as "clean and tidy". The houses were multi-storied and made of adode bricks. "They make very fine tortillas," Espejo commented, and the Pueblos also served the Spanish turkeys, beans, corns, and pumpkins. The people "did not seem to be bellicose". The southernmost Pueblos had only clubs for weapons plus a few "poor Turkish bows and poorer arrows". Further north, the Indians were better armed and more aggressive. Some of the Pueblo towns were large, Espejo described Zia as having 1,000 houses and 4,000 men and boys. In their farming, the Pueblos used irrigation "with canals and dams, built as if by Spaniards". The only Spanish influence that Espejo noted among the Pueblos was their desire for iron. They would steal any iron article they could find.
Agriculture in Sudan
The waters of the Nile in Sudan have been used for centuries for traditional irrigation, taking advantage of the annual Nile flood. Some use of this method still continued in the early 1990s, and the traditional shaduf (a device to raise water) and waterwheel were also used to lift water to fields in local irrigation projects but were rapidly being replaced by more efficient mechanized pump systems. Among the first efforts to employ irrigation for modern commercial cropping was the use of the floodwaters of the Qash River and the Baraka River (both of which originate in Ethiopia) in eastern Sudan to grow cotton on their deltas. This project was started in the late 1860s by the Egyptian governor and continued until interrupted by the turbulent period of the 1880s, leading to the reconquest of the country by the British in 1899. Cultivation was resumed in 1896 in the Baraka Delta in the Tawkar area, but in the Qash Delta it only resumed after World War I. Between 1924 and 1926, canals were built in the latter delta to control the flood; sandstorms made canals unfeasible in the Baraka. Between the 1940s and the 1970s, various projects were developed to irrigate land. In 1982 both deltas yielded only one crop a year, watered by the flood. Adequate groundwater, however, offered the eventual possibility of using pump irrigation from local wells for additional cropping or for supplementing any flood shortages.
