Tepehuan dwelling is a rectangular two-room construction built on a platform of earth that has been prepared by continual watering, sweeping, and hollowing out. The walls are made of stone and adobe and the roof is thatched with grass. One room is used for cooking and the other for sleeping. There are variations in the construction of homes in different villages, depending on available materials. Where sawmills are accessible, lumber is used in the construction of community and residential buildings. Economy Ódami Practically every household grows food for its own consumption on small plots. Maize, squashes, and beans are the staple crops whereas wheat, barley, potatoes, oats, and peas are also commonly grown. Tobacco and chilies are grown in the lowlands. The dibble stick and wooden plows drawn by oxen are adjuncts to farming. A dibble stick is a sharpened pole used to punch a hole in the plowed earth or a slashand-burn plot for planting seeds. One season for cultivating is available in the highlands compared to two in the hotter lowlands. Maize fields are cultivated separately from garden plots dedicated to the other vegetables. Old World fruit trees, introduced by the missionaries, are also tended near the settlements. In the highlands, there are small groves of fig, pomegranate, peach, and apple trees, and, in the hot canyon lands, there are orange and lemon trees. Gathering wild foods is still an important activity as well. Seasonal wild fruits, piñon nuts, walnuts, and edible species of acorns are collected, as is crude honey. Certain insects, reptiles, grubs, and the occasional rattlesnake round out the choices of consumable undomesticated resources. Hunting and trapping also supplement the diet, and deer and wild turkeys are the most highly prized game. The raising of chickens and, to a lesser extent, turkeys and pigs provides additional sustenance. Livestock are a source of wealth and prestige. Horses—ridden for transportation—and burros and mules—used as pack animals—are much valued. There are many sheep and goats, which are prized for their wool and as food during fiestas. For the most part, the family is the unit of production and consumption, but this configuration is changing. One frequent pattern is an unfortunate circle of need. During hard times, some of the maize harvest is sold, but because most families only grow enough in their gardens to feed themselves, the maize is bought back at an inflated price before the next
