Metate and Mano. Typewritten on photo sleeve: "The Indians used these stones to grind all kinds of wild seeds; sometimes they used them to make meal of the pine nuts. The metate (large stone) is 18 inches across. The mano, or hand stone, is a heavy rock. Both have been worn smooth by use." N[evada] T[est] S[ite] News]
