As soon as the outfit had got into camp in the afternoon, Joe went to the cook tent and borrowed Frank's spade, and going down near to the stream and choosing a place where the grass grew fairly thick, he began to dig a hole considerably larger than a water bucket. When he had made the hole a foot and a half deep, he got into it and tramped down the soil on the bottom, scraping up anything that was loose and finally leaving a fairly smooth and hard surface. While working at this, he asked Jack to go to the wagon and bring the skin, and also the skull of the deer, which was tied to one of the bows of the wagon near the hide. Jack presently returned with both. "I didn't know you had saved the skull, Joe," he said; "it looks as if it had been partly cooked. Did you save it for the brains?" "Just for that," was the reply. "You know, of course, that the brains is a pretty important part of the operation of tanning. I did think I might get the brains of a beef from some animal that we'd kill, but of course we never could be sure of having a chance to do our tanning just after the beef had been killed, so I thought I'd save this skull; and to keep it from spoiling I stuck it in the ashes that night we skinned the deer, and hauled some coals over it, and asked Frank not to throw it away if he found it. It sort of cooked and dried during the night, and doesn't seem to have spoiled a bit." By this time the hole seemed to suit Joe. He took the deer's hide and cut the string which bound it to the willow hoop, then began to fold it--taking care not to break the skin--until he made it into a more or less square package, flesh side out, somewhat less in size than the bottom of the hole. He placed it in the bottom of the hole, and put on it a rather heavy stone to hold it in position. Then, taking a bucket, he went down to the stream and brought two or three bucketfuls of water which he poured into the hole until it was almost full. "This hole is close to the camp, and nothing is likely to disturb the skin during the night," he said; "but the coyotes might find it, and I don't mean to take any chances, so I'm going to cover it up. Maybe Frank will lend us the tail gate of his wagon to put over it. I'll ask him, anyhow." The cook, on being appealed to, declined to lend the tail gate of the cook wagon. "Why don't you get the tail gate of the bed wagon and use that?" he suggested. Joe at once did so. He carried the end gate out and placed it over the hole, and the boys put two or three heavy stones on it. "Now," said Joe, "I need a sort of beam to use in scraping the hair off this hide, and I reckon one of these young cottonwoods will do. I wish we had a tree right here to rest it against." "What's the matter with that box elder over there with the low fork? If you make your pole long enough you can rest it in that fork."
