Dick did not believe that the timber wolves, after suffering so much in the pursuit of Albert, would venture again to attack either his brother or himself. He knew that the wolf was one of the shrewdest of all animals, and that, unless the circumstances were very unusual indeed, the sight of a gun would be sufficient to warn them off. Nevertheless, he decided to begin a campaign against them, though he had to wait a day or two until Albert's shaken nerves were restored.  
They wished to save their ammunition as much as possible, and they built three large dead falls, in which they caught six or seven great wolves, despite their cunning. In addition they hunted them with rifles with great patience and care, never risking a shot until they felt quite sure that it would find a vital spot. In this manner they slew about fifteen more, and by that time the wolves were thoroughly terrified. The scent of the beings carrying sticks which poured forth death and destruction at almost any distance, was sufficient to send the boldest band of timber wolves scurrying into the shadows of the deepest forest in search of hiding and safety.
 
The snow melted and poured in a thousand streams from the mountains. The river and all the creeks and brooks roared in torrents, the earth soaked in water, and the two boys spent much of the time indoors making new clothing, repairing traps and nets, and fashioning all kinds of little implements that were of use in their daily life. They could realize, only because they now had to make them, how numerous such implements were. Yet they made toasting sticks of hard wood, carved out wooden platters, constructed a rude but serviceable dining table, added to their supply of traps of various kinds, and finally made two large baskets of split willow. The last task was not as difficult as some others, as both had seen and taken a part in basket making in Illinois. The cabin was now crowded to inconvenience. Over their beds, from side to side, and up under the sloping roof, they had fastened poles, and from all of these hung furs and skins, buffalo, deer, wolf, wild cat, beaver, wolverine, and others, and also stores of jerked game. The Annex was in the same crowded condition. The boys had carried the hollow somewhat higher up with their axes, but the extension gave them far less room than they needed.
 
"It's just this, Dick," said Albert, "we getting so rich that we don't know what to do with all our property. I used to think it a joke that the rich were unhappy, but now I see where their trouble comes in."
 
"I know that the trappers cache their furs, that is, bury them or hide them until they can take them away," said Dick, "but we don't know how to bury furs so they'll keep all right. Still, we've got to find a new place of some kind. Besides, it would be better to have them hidden where only you and I could find them, Al. Maybe we can find such a place."
 
Albert agreed, and they began a search along the cliffs. Dick knew that extensive rocky formations must mean a cave or an opening of some kind, if they only looked long enough for it, at last they found in the side of a slope a place that he thought could be made to suit. It was a rocky hollow running back about fifteen feet, and with a height and width of perhaps ten feet. It was approached by an opening about four feet in height and two feet in width. Dick wondered at first that it had not been used as a den by some wild animal, but surmised that the steepness of the ascent and the extreme roughness of the rocky floor had kept them out.
 
But these very qualities recommended the hollow to the boys for the use that they intended it. Its position in the side of the cliff made it a hard place to find, and the solid rock of its floor, walls, and roof insured the dryness that was necessary for the storage of their furs.
 
"We'll call this the Cliff House," said Albert, "and we'll take possession at once."
 
They broke off the sharper of the stone projections with their ax heads, and then began the transfer of the furs. It was no light task to carry them up the step slope to the Cliff House, but, forced to do all things for themselves, they had learned perseverance, and they carried all their stock of beaver furs and all the buffalo robes and bearskins, except those in actual use, together with a goodly portion of the wolfskins, elk hides, and others.
 
Dick made a rude but heavy door which fitted well enough into the opening to keep out any wild animal, no matter how small, and in front of it, in a little patch of soft soil, they set out two transplanted pine bushes which seemed to take root, and which Dick was sure would grow in the spring.
 
When the boys looked up from the bottom of the slope, they saw no trace of the Cliff House, only an expanse of rock, save a little patch of earth where two tiny pines were growing.
 
"Nobody but ourselves will ever find our furs!" exclaimed Dick exultingly. "The most cunning Indian would not dream that anything was hidden up there behind those little pines, and the furs will keep as well inside as if they were in the best storehouse ever built."
 
The discovery and use of the rock cache was a great relief to both. Their cabin had become so crowded with furs and stores, that the air was often thick and heavy, and they did not have what Dick called elbow room. Now they used the cabin almost exclusively for living purposes. Most of the stores were in the Annex, while the dry and solid Cliff House held the furs.
 
"Have you thought, Dick, what you and I are?" asked Albert.
 
"I don't catch your meaning."
 
"We're aristocrats of the first water, Mr. Richard Howard and Mr. Albert Howard, the Mountain Kings. We can't get along with less than four residences. We live in Castle Howard, the main mansion, superior to anything of its kind in a vast region; then we have the Annex, a tower used chiefly as a supply room and treasure chest; then the Suburban Villa, a light, airy place of graceful architecture, very suitable as a summer residence, and now we have the Cliff House, in a lofty and commanding position noted for its wonderful view. We are really a fortunate pair, Dick."
 
"I've been thinking that for sometime," replied Dick rather gravely.
 
Hitherto they had confined their operations chiefly to their own side of the lake, but as they ranged farther and farther in search of furs they began to prowl among the canyons and narrow valleys in the mountains on the other side. They made, rather far up the northern side, some valuable catches of beaver, but in order to return with them, they were compelled to come around either the northern or southern end of the lake, and the round trip was tremendously long and tiring.
 
"It's part of a man's business to economize time and strength," said Dick, "and we must do it. You and I, Al, are going to make a canoe."
 
"How?"
 
"I don't know just yet, but I'm studying it out. The idea will jump out of my head in two or three days."
 
It was four days before it jumped, but when it did, it jumped to some purpose.
 
"First, we'll make a dugout," he said. "We've got the tools—axes, knives, saws, and augers—and we'd better start with that."
 
They cut down a big and perfectly straight pine and chose a length of about twelve feet from the largest part of the trunk. Both boys had seen dugouts, and they knew, in a general way, how to proceed. Their native intelligence supplied the rest.
 
They cut off one side of the log until it was flat, thus making the bottom for the future canoe. They cut the opposite side away in the well-known curve that a boat makes, low in the middle and high at each end. This part of the work was done with great caution, but Dick had an artistic eye, and they made a fairly good curve. Next they began the tedious and laborious work of digging out, using axes, hatchets, and chisel.
 
This was a genuine test of Albert's new strength, but he stood it nobly. They chipped away for a long time, until the wood on the sides and bottom was thin but strong enough to stand any pressure. Then they made the proper angle and curve of bow and stern, cut and made two stout broad paddles, and their dugout was ready—a long canoe with a fairly good width, as the original log had been more than two feet in diameter. It was both light and strong, and, raising it on their shoulders, they carried it down to the lake where they put it in the water.
 
Albert, full of enthusiasm, sprang into the canoe and made a mighty sweep with his paddle. The light dugout shot away, tipped on one side, and as Albert made another sweep with his paddle to right it, it turned over, bottom side up, casting the rash young paddler into ten feet of pure cold water. Albert came up with a mighty splash and sputter. He was a good swimmer, and he had also retained hold of the paddle unconsciously, perhaps. Dick regarded him contemplatively from the land. He had no idea of jumping in. One wet and cold boy was enough. Beside, rashness deserved its punishment.
 
"Get the canoe before it floats farther away," he called out, "and tow it to land. It has cost us too much work to be lost out on the lake."
 
Albert swam to the canoe, which was now a dozen yards away, and quickly towed it and the paddle to land. There, shivering, the water running from him in streams, he stepped upon the solid earth.
 
"Run to the cabin as fast as you can," said Dick. "Take off those wet things, rub yourself down before the fire; then put on dry clothes and come back here and help me."
 
Albert needed no urging, but it seemed to him that he would freeze before he reached the cabin, short as the distance was. Fortunately, there was a good fire on the hearth, and, after he had rubbed down and put on his dry, warm suit of deerskin, he never felt finer in his life. He returned to the lake, but he felt sheepish on the way. That had been a rash movement of his, overenthusiastic, but he had been properly punished. His chagrin was increased when he saw Dick a considerable distance out on the lake in the canoe, driving it about in graceful curves with long sweeps of his paddle.
 
"This is the way it ought to be done," called out Dick cheerily.
"Behold me, Richard Howard, the king of canoe men!"
 
"You've been practicing while I was gone!" exclaimed Albert.
 
"No doubt of it, my young friend, and that is why you see me showing such skill, grace, and knowledge. I give you the same recipe without charge: Look before you leap, especially if you're going to leap into a canoe. Now we'll try it together."
 
He brought the canoe back to land, Albert got in cautiously, and for the rest of the day they practiced paddling, both together and alone. Albert got another ducking, and Dick, in a moment of overconfidence, got one, too, somewhat to Albert's pleasure and relief, as it has been truly said that misery loves company, but in two or three days they learned to use the canoe with ease. Then, either together or alone, they would paddle boldly the full length of the lake, and soon acquired dexterity enough to use it for freight, too; that is, they would bring back in it across the lake anything that they had shot or trapped on the other side.
 
So completely had they lost count of time that Dick had an idea spring was coming, but winter suddenly shut down upon them again. It did not arrive with wind and snow this time, but in the night a wave of cold came down from the north so intense that the sheltered valley even did not repel it.
 
Dick and Albert did not appreciate how really cold it was until they went from the cabin into the clear morning air, when they were warned by the numbing sensation that assailed their ears and noses. They hurried into the house and thawed out their faces, which stung greatly as they were exposed to the fire. Remembering the experiences of their early boyhood, they applied cold water freely, which allayed the stinging. After that they were very careful to wrap up fingers, ears, and noses when they went forth.
 
Now, the channel that Albert had made from the water of the hot spring proved of great use. The water that came boiling from the earth cooled off rapidly, but it was not yet frozen when it reached the side of Castle Howard, and they could make use of it.
 
The very first morning they found their new boat, of which they were so proud, hard and fast with ten inches of solid ice all around it. Albert suggested leaving it there.
 
"We have no need of it so long as the lake is covered with ice," he said, "and when the ice melts it will be released."
 
But Dick looked a little farther. The ice might press in on it and crush it, and hence Albert and he cut it out with axes, after which they put it in the lee of the cabin. Meanwhile, when they wished to reach the traps on the farther side of the lake, they crossed it on the ice, and, presuming that the cold might last long, they easily made a rude sledge which they used in place of the canoe.
 
"If we can't go through the water, we can at least go over it," said Albert.
 
While the great cold lasted, a period of about two weeks, the boys went on no errands except to their traps. The cold was so intense that often they could hear the logs of Castle Howard contracting with a sound like pistol shots. Then they would build the fire high and sit comfortably before it. Fortunately, the valley afforded plenty of fuel. Both boys wished now that they had a few books, but books were out of the question, and they sought always to keep themselves busy with the tasks that their life in the valley entailed upon them. Both knew that this was best.
 
The cold was so great that even the wild animals suffered from it. The timber wolves, despite their terrible lessons, were driven by it down the valley, and at night a stray one now and then would howl mournfully near the cabin.
 
"He's a robber and would like to be a murderer," Albert would say, "but he probably smells this jerked buffalo meat that I'm cooking and I'm sorry for him."
 
But the wolves were careful to keep out of rifle shot.
 
Dick made one trip up the valley and found about fifty buffaloes sheltered in a deep ravine and clustering close together for warmth. They were quite thin, as the grass, although it had been protected by the snow, was very scanty at that period of the year. Dick could have obtained a number of good robes, but he spared them.
 
"Maybe I won't be so soft-hearted when the spring comes and you are fatter," he said.
 
The two, about this time, took stock of their ammunition, which was the most vital of all things to them. For sometime they had used both the shot and ball cartridges only in cases of necessity, and they were relying more and more on traps, continually devising new kinds, their skill and ingenuity increasing with practice.
 
Dick had brought a great store of cartridges from the last train, especially from the unrifled wagon in the gully, and both boys were surprised to see how many they had left. They had enough to last a long time, according to their present mode of life.
 
"If you are willing, that settles it," said Dick.
 
"If I am willing for what?" asked Albert.
 
"Willing to stay over another year. You see, Al, we've wandered into a happy hunting ground. There are more furs, by the hundreds, for the taking, and it seems that this is a lost valley. Nobody else comes here. Besides, you are doing wonderfully. All that old trouble is gone, and we want it to stay gone. If we stay here another year, and you continue to eat the way you do and grow the way you do, you'll be able to take a buffalo by the horns and wring its neck."
 
Albert grinned pleasantly at his brother.
 
"You don't have to beg me to stay," he said. "I like this valley. It has given me life and what is to be our fortune, our furs. Why not do all we can while we can? I'm in favor of the extra year, Dick."
 
"Then no more need be said about it. The Cliff House isn't half full of furs yet, but in another year we can fill it."
 
The great cold began to break up, the ice on the lake grew thinner and thinner and then disappeared, much of the big game left the valley, the winds from the north ceased to blow, and in their stead came breezes from the south, tipped with warmth. Dick knew that spring was near. It was no guess, he could feel it in every bone of him, and he rejoiced. He had had enough of winter, and it gave him the keenest pleasure when he saw tiny blades of new grass peeping up in sheltered places here and there.
 
Dick, although he was not conscious of it, had changed almost as much as Albert in the last eight or nine months. He had had no weak chest and throat to cure, but his vigorous young frame had responded nobly to the stimulus of self-reliant life. The physical experience, as well as the m............
