     As many as one thousand years ago in the Southwest, the Hopi and Zuni Indians of North

     America were building with adobe-sunbaked brick plastered with mud. Their homes

looked remarkably like modern apartment houses. Some were four stories high and contained

quarters for perhaps thousand people, along with store rooms for grain and other goods.

     These buildings were usually put up against cliffs, both to make construction easier and for

defense against enemies. They were really villages in themselves, as later Spanish explorers

must have realized since they called them "pueblos", which is Spanish for town.

     The people of the pueblos raised what are called "the three sisters"-corn, beans, and

squash. They made excellent pottery and wove marvelous baskets, some so fine that they

could hold water. The Southwest has always been a dry country, where water is scarce. The

     Hopi and Zuni brought water from streams to their fields and gardens through irrigation

ditches. Water was so important that it played a major role in their religion. They developed

elaborate ceremonies and religious rituals to bring rain.

     The way of life of lesssettled groups was simpler and more strongly influenced by nature.

     Small tribes such as the Shoshone and Ute wandered the dry and mountainous lands between

the Rocky Mountains and the Pacific Ocean. They gathered seeds and hunted small animals

such as rabbits and snakes.In the Far North the ancestors of today's Inuit hunted seals,

walruses, and the great whales. They lived right on the frozen seas in shelters called igloos

built of blocks of packed snow. When summer came, they fished for salmon and hunted the

lordly caribou.

     The Cheyenne, Pawnee, and Sioux tribes, known as the Plains Indians, lived on the

grasslands between the Rocky Mountains and the Mississippi River. They hunted bison

commonly called the buffalo. Its meat was the chief food of these tribes, and its hide was

used to make their clothing and the covering of their tents and tipis.
