Still another element is introduced in another form of the game, which increases the opportunity afforded the one who manipulates the bones for dexterity. This form of the game is repeatedly alluded to by Powers. While relating the habits and customs of the Gualala, whose homes were near Fort Ross, he describes what he calls the gambling game of "_wi_ and _tep_" and says that one description with slight variations will answer for nearly all the tribes of central and southern California. After describing the making up of the pool of stakes, he adds: "They gamble with four cylinders of bone about two inches long, two of which are plain, and two marked with rings and strings tied round the middle. The game is conducted by four old and experienced men, frequently grey heads, two for each party, squatting on their knees on opposite sides of the fire. They have before them a quantity of fine dry grass, and with their hands in rapid and juggling motions before and behind them, they roll up each piece of bone in a little ball and the opposite party presently guess in which hand is the marked bone. Generally only one guesses at a time, which he does with the word '_lep_' (marked one), and '_wi_' (plain one). If he guesses right for both players, they simply toss the bones over to him and his partner, and nothing is scored on either side. If he guesses right for one and wrong for the other, the one for whom he guessed right is 'out', but his partner rolls up the bones for another trial, and the guesser forfeits to them one of his twelve counters. If he guesses wrong for both, they still keep on and he forfeits two counters. There are only twelve counters and when they have been all won over to one side or the other, the game is ended. [Footnote: Powers in Contributions to North American Ethnology, Vol. III, pp. 90-152; 189-332.] Sometimes the same game was played without going through the formality of wrapping the pieces in grass, simply shaking them in the hands as a preliminary for the guessing.
