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.
Mezquital Valley
Since the latter 20th century, the valley has become an important agricultural center for the state of Hidalgo, growing corn, beans, wheat, onions, tomatoes, cactus fruit, and peaches; the valley also produces one-quarter of all green chili peppers grown in Mexico. It also produces alfalfa, principally used to feed the area's cattle. A small but important quantity of lettuce, cabbage, cilantro, radishes, carrots, spinach, and parsley is grown. There are also a number of fish farms, especially in Tezontepec de Aldama. About 61% of the population works in agriculture, which has been made possible by the diversion of wastewater from the neighboring Valley of Mexico through the Tula River. Sixty percent of the farmland is irrigated with wastewater. Thirty nine percent of the farmland is dependent on clean water sources such as wells and rain, and only 0.38 percent is irrigated with treated water. The areas most dependent on wastewater are: Actopan, Ajacuba, Alfajayucan, Atitalaquía, Atotonilco de Tula, Francisco I. Madero, Chilcuautla, Mixquihuala, San Salvador, Tasquillo, Tetepango, Tezontepec, Tlahuelilpan, and Tlaxcoapan. The areas that use wastewater are more productive, as the water contains phosphorus and nitrogen, but the products are more likely to have problems with contaminants. These contaminants also pose a risk to farm workers and their families.
