"That's all," said Jack. "Uncle George showed me a picture of a skull once, and I remember that it was longer than a wolf's skull, and it had two great big gnawing teeth reaching down from the front of the jaw."

"Powerful strange things there used to be on this earth a long time ago," said Hugh, in a meditative tone.

"Yes, indeed," answered Jack, "and think how little we, any of us, know about those things. Even the smartest men, those who have given up all their time to studying these things, don't seem to know much about those old times. I know it's awful easy to ask them questions that they can't answer."

"I suppose a man of that kind doesn't want to say anything unless he's dead sure it's so," said Hugh. "Likely enough he's made his reputation by always being right, and he's afraid to make any guesses."

"Maybe that is it," said Jack, "but I remember one time going to New Haven with my uncle, and we went into the Peabody Museum, and one of the professors there, a Mr. Marsh, took us around and showed us the greatest lot of bones you ever saw. He could tell us a great many things about the skeletons and parts of skeletons that he showed us, but I know my uncle asked him a great many questions about other things, and he would just laugh and say he didn't know anything about it, and nobody else did."

"Well," said Hugh, "it's each man to his trade. I suppose I can hunt and trap and know something about animals, and these professors work over their birds and their bugs and their bones. Some of the stories they tell are pretty hard to believe, and yet I reckon they are all true."

"Oh, I guess so," said Jack.

The next morning before daylight had fairly broken, Jack was afoot and on his way out to the horses. They were brought in and tied up to the willows, their saddles put on and ropes coiled, picket pins got together, and all the various property of the camp, which so easily becomes scattered about, was collected before breakfast was ready.

The bear skin, which had now been drying for three or four days, was taken from the ground and brought into camp. Hugh, when he looked at it, said that it was in first-class condition and had not been burned by the sun.

"Save all these pins, son," he said, "wrap them up in a gunny sack; they may be useful to us later on, and may save us half a day's whittling."
