They found the beaver father in the mountains, as Dick had surmised, and trapped them in great abundance. This was by far their most valuable discovery, and they soon had a pack of sixty skins, which Dick said would be worth more than a thousand dollars in any good market. They also made destructive inroads upon the timber wolves, the hides of which were more valuable than those of any other wolf. In fact, they made such havoc that the shrewd timber wolf deserted the valley almost entirely.
As the boys now made their fur hunting a business, they attended to every detail with the greatest care. They always removed the skin immediately after the death of the animal, or, if taken in a trap, as soon after as possible. Every particle of fat or flesh was removed from the inside of the skin, and they were careful at the same time never to cut into the skin itself, as they knew that the piercing of a fur with a knife would injure its value greatly. Then the skin was put to dry in a cold, airy place, free alike from the rays of the sun or the heat of a fire. They built near the cabin a high scaffold for such purposes, too high and strong for any wild beast to tear down or to reach the furs upon it. Then they built above this on additional poles a strongly thatched bark roof that would protect the skins from rain, and there they cured them in security.
"I've heard," said Dick, "that some trappers put preparations or compounds on the skins in order to cure them, but since we don't have any preparations or compounds we won't use them. Besides, our furs seem to cure up well enough without them."
Dick was right. The cold, dry air of the mountains cured them admirably. Two or three times they thought to help along the process by rubbing salt upon the inner sides. They could always get plenty of salt by boiling out water from the salt springs, but as they seemed to do as well without it, they ceased to take the trouble.
The boys were so absorbed now in their interesting and profitable tasks that they lost all count of the days. They knew they were far advanced into a splendid open winter, but it is probably that they could not have guessed within a week of the exact day. However, that was a question of which they thought little. Albert's health and strength continued to improve, and with the mental stimulus added to the physical, the tide of life was flowing very high for both.
They now undertook a new work in order to facilitate their trapping operations. The beaver stream, and another that they found a little later, ran far back into the mountains, and the best trapping place was about ten miles away. After a day's work around the beaver pond, they had to choose between a long journey in the night to the cabin or sleeping in the open, the latter not a pleasant thing since the nights had become so cold. Hence, they began the erection of a bark shanty in a well-sheltered cove near the most important of the beaver localities. This was a work of much labor, but, as in all other cases, they persisted until the result was achieved triumphantly.
They drove two stout, forked poles deep into the ground, leaving a projection of about eight feet above the earth. The poles themselves were about eight feet apart. From fork to fork they placed a strong ridgepole. Then they rested against the ridgepole from either side other and smaller poles at an angle of forty or fifty degrees. The sloping poles were about a foot and a half apart. These poles were like the scantling or inside framework of a wooden house and they covered it all with spruce and birch bark, beginning at the bottom and allowing each piece to overlap the one beneath it, after the fashion of a shingled roof. They secured pieces partly with wooden pegs and partly with other and heavier wooden poles leaned against them. One end of the shelter was closed up with bark wholly, secured with wooden pegs, and the other end was left open in order that its tenants might face the fire which would be built three or four feet in front of it. They packed the floor with dead leaves, and put on the top of the leaves a layer of thick bark with the smooth side upward.
The bark shanty was within a clump of trees, and its open side was not fifteen feet from the face of an abrupt cliff. Hence there was never any wind to drive the smoke from the fire back into their faces, and, wrapped in their furs, they slept as snugly in the shanty as if they had been in the cabin itself. But they were too wise to leave anything there in their absence, knowing that it was not sufficient protection against the larger wild animals. In fact, a big grizzly, one night when they were at the cabin, thrust his nose into the shanty and, lumbering about in an awkward and perhaps frightened manner, knocked off half of one of the bark sides. It took nearly a day's work to repair the damage, and it put Dick in an ill humor.
"I'd like to get a shot at that bear!" he exclaimed. "He had no business trying to come into a house when he was not invited."
"But he is an older settler than we are," said Albert, in a whimsical tone.
