When the Piute came to a spring, the first thing he did was to look about for a flat rock which he was sure to find if a member of his tribe had previously been there. Kneeling, he would skim the water from the surface and dash it upon this rock. Then he smelled the rock. If there was an odor of onion or garlic, he knew it contained arsenic and was deadly. Naturally, he would be concerned about another water hole. He had only to look about him. He would find partially imbedded in the earth several stones fixed in the form of a circle not entirely closed. The opening pointed in the direction of the next water. The distance to that water was indicated by stones inside the circle. There he would find for example, three stones pointing toward the opening. He knew that each of those stones indicated one “sleep.” Therefore he would have to sleep three times before he got there. In other words, it was three days’ journey. But which of these trails leading to the water should he take? There might be several trails converging at the water hole. The matter was decided for him. He walked along each of those trails for a few feet. Beside one of them he would find an oblong stone. By its shape and position he knew that was the trail that led to the next water. Under such circumstances a man would perhaps wonder if upon arrival at the next water hole he would find that water also unfit to use. The information was at hand. If, upon top of that oblong stone he found a smaller stone placed crosswise and white in color, he knew the water would be good water. If a piece of black malpai was there instead of the white stone, he knew the next water would be poison also. Not infrequently he would find other information at the water hole if there were boulders about, or chalky cliffs upon which the Indian could place his picture writing. If he saw the crude drawing of a lone man, it indicated that the land about was uninhabited except by hunters, but if upon the pictured torso were marks indicating the breasts of a woman, he knew there was a settlement about and he would find squaws and children and something to eat. Frequently other information was left for this wayfaring Indian. Under conspicuous stones about, he might find a feather with a hole punched through it or one that was notched. The former indicated that one had been there who had killed his man. The notch indicated that he had cut a throat. Since there was a difference between the moccasins of Indian tribes, the dust about would often inform him whether the buck who went before was friend or enemy.
