As there was a difference in the natural products and resources of different sections of the country, there was a system of reciprocal trade in the exchange of the different desirable commodities. Sometimes commerce between tribes extended for a long distance, as, for instance, the Indians on the western side of the Sierra Nevada Mountains were entirely dependent upon the Pai-utes (Pye-yutes´) on the eastern side for the obsidian, a kind of volcanic glass, from which they made the points for their most deadly arrows, used in hunting large game or when in mortal combat with their enemies. They were also dependent upon the Pai-utes for their supply of salt for domestic use, which came in solid blocks as quarried from salt mines, said to be two days' travel on foot from Mono Lake.
From the Indians at or near the Catholic Missions to the South, on the Pacific Coast, they got their hunting knives of iron or steel, and sea shells of various kinds, for personal or dress ornaments, and also to be used as money. From the same source they obtained beads of various forms, sizes and colors, cheap jewelry and other fancy articles, a few blankets, and pieces of red bunting, strips of which the chiefs and head men wore around their heads as badges, indicating their official positions.
COMMUNICATION.
They had a very efficient system of quickly spreading important news by relays of special couriers, who took the news to the first stations or tribes in different directions, where others took the verbal dispatches and ran to the next station, and so on, so that all tribes within an area of a hundred miles would get the good or bad tidings within a few hours. In this manner important communication was kept up between the different tribes. They also had well organized signal systems, by fires in the night and smoke by day, on high points of observation—variations in the lights (either steady, bright or flashing) indicating somewhat the character of the tidings thus given.
DWELLINGS.
Their winter huts, or o´-chums, as they termed them, were invariably of a conical form, made with small poles, and covered with the bark of the incense cedar (Libocedrus decurrens). A few poles ten or twelve feet long were set in the ground around an area of about twelve feet in diameter, with their tops inclined together. The outside was then closely covered with long strips of the cedar bark, making it perfectly water-tight. An opening was left on the south side for an entrance, which could be readily closed with a portable door. An opening was also left at the top for the escape of the smoke, a fire being kindled in the center inside.

INDIAN O´-CHUM.
This style of house, made of cedar poles covered with bark, is more easily heated than any other form of dwelling known.
One of these huts would hold a family of a half-dozen persons, with all their household property, dogs included; and there is no other form of a single-room dwelling that can be kept warm and comfortable in cold weather with so little fire, as this Indian o´-chum.
