The door was made, and now came the task to "hang" it. "Hang"

was merely a metaphorical word, as they fitted it into place instead. The wood all around the opening was about a foot thick, and they cut it out somewhat after the fashion of the lintels of a doorway. Then they fitted in the door, which rested securely in its grooves, but they knew that the claws of a grizzly bear or mountain lion might scratch it out, and they intended to make it secure against any such mischance.

With the aid of hatchet and auger they put three wooden hooks on either side of the doorway, exactly like those that defend the door of a frontier cabin, and into these they dropped three stout bars. It was true that the bars were on the outside, but no wild animal would have the intelligence enough to pry up those three bars and scratch the door out of place. Moreover, it could not happen by accident. It took them three laborious days to make and fit this door, but when the task was done they contemplated it with just pride.

"I call that about the finest piece of carpenter's work ever done in these mountains," said Albert in tones suffused with satisfaction.

"Of course," said d.i.c.k. "Why shouldn't it be, when the best carpenters in the world did the job?"

The two laughed, but their pride was real and no jest. It was late in the afternoon when they finished this task, and on the way to the cabin Albert suddenly turned white and reeled. d.i.c.k caught him, but he remained faint for sometime. He had overtasked himself, and when they reached the cabin d.i.c.k made him lie down on the great buffalo robe while he cooked supper.

But, contrary to his former habit, Albert revived rapidly. The color returned to his face and he sprang up presently, saying that he was hungry enough to eat a whole elk. d.i.c.k felt a might sense of relief. Albert in his zeal had merely overexerted himself. It was not any relapse. "Here's the elk steak and you can eat ten pounds of it if you want it," he said.

They began early the next morning to move supplies to the Annex.

High up in the hollow they hung great quant.i.ties of dried meat of buffalo, elk, and mule deer. They also stored there several elk and mule deer skins, two wolf skins, and other supplies that they thought they would not need for a while. But in the main it was what they called a smokehouse, as it was universally known in the Mississippi Valley, their former home--that is, a place for keeping meat cured or to be cured.

This task filled the entire day, and when the door was securely fastened in place they returned to the cabin. After supper d.i.c.k opened the window, from which they could see the Annex, as they had cut away a quant.i.ty of the intervening bushes. Albert meanwhile put out the last coals of the fire. Then he joined d.i.c.k at the window. Both had an idea that they were going to see something interesting.

The valley filled with darkness, but the moon came out, and, growing used to the darkness, they could see the Annex fairly well.

d.i.c.k wet his finger and held it up.

"The wind is blowing from the Annex toward us," he said.

"That's good," said Albert, nodding.

They watched for a long time, hearing only the dry rustling of the light wind among the bare boughs, but at last d.i.c.k softly pushed his shoulder against Albert's. Albert nodded again, with comprehension. A small dark animal came into the open s.p.a.ce around the Annex. The boys had difficulty in tracing his outlines at first, but once they had them fixed, they followed his movements with ease. He advanced furtively, stopping at intervals evidently both to listen and look. Some other of his kind, or not of his kind, might be on the same quest and it was his business to know.

"Is it a fox?" whispered Albert.

"I think not," replied d.i.c.k in the same tone. "It must be a wolverine. He scents the good things in the Annex and he wants, oh, how he wants, the taste of them!"

The little dark animal, after delicate maneuvering, came close up to the tree, and they saw him push his nose against the cold bark.

"I know just how he feels," whispered Albert with some sympathy.

"It's all there, but he must know the quest is hopeless."

The little animal went all around the tree nosing the cold bark, and then stopped again at the side of the door.

"No use, sir," whispered Albert. "That door won't open just because you're hungry."

The little animal suddenly c.o.c.ked up his head and darted swiftly away into the shadows. But another and somewhat larger beast came creeping into the open, advancing with caution toward the Annex.

"Aha!" whispered d.i.c.k. "Little fellow displaced by a bigger one. That must be a wild cat."

The wild cat went through the same performance. He nosed eagerly at the door, circled the tree two or three times, but always came back to the place where that tempting, well-nigh irresistible odor a.s.sailed him. The boys heard a low growl and the scratching of sharp claws on the door.

"Now he's swearing and fighting," whispered Albert, "but it will do him no good. Save your throat and your claws, old fellow."

"Look, he's gone!" whispered d.i.c.k.

The wild cat suddenly tucked his tail between his legs and fled from the opening so swiftly that they could scarcely see him go.

"And here comes his successor," whispered Albert. "I suppose, d.i.c.k, we might call this an arithmetical or geometrical progression."

An enormous timber wolf stalked into the clear s.p.a.ce. He bore no resemblance to the mean, sneaking little coyote of the prairie.

As he stood upright his white teeth could be seen, and there was the slaver of hunger on his lips. He, too, was restive, watchful, and suspicious, but it did not seem to either d.i.c.k or Albert that his movements betokened fear. There was strength in his long, lean body, and ferocity in his little red eyes.

"What a hideous brute!" whispered Albert, shuddering.

"And as wicked as he is ugly," replied d.i.c.k. "I hate the sight of these timber wolves. I don't wonder that the wild cat made himself scarce so quickly."

"And he's surely hungry!" said Albert. "See how he stretches out his head toward our Annex, as if he would devour everything inside it!"

Albert was right. The big wolf was hungry, hungry through and through, and the odor that came from the tree was exquisite and permeating; it was a mingled odor of many things and everything was good. He had never before known a tree to give forth such a delightful aroma and he thrilled in every wolfish fiber as it tickled his nostrils.

He approached the tree with all the caution of his cautious and crafty race, and, as he laid his nose upon the bark, that mingled aroma of many things good grew so keen and powerful that he came as near as a big wolf can to fainting with delight. He pushed at the places where the door fitted into the tree, but nothing yielded. Those keen and powerful odors that penetrated delightfully to every marrow of him were still there, but he could not reach their source. A certain disappointment, a vague fear of failure mingled with his antic.i.p.ation, and as the wolverine and the wild cat had done, he moved uneasily around the tree, scratching at the bark, and now and then biting it with teeth that were very long and cruel.

His troubled circuit brought him back to the door, where the aroma was finest and strongest. There he tore at the lowest bar with tooth and claw, but it did not move. He had the aroma and nothing more, and no big, strong wolf can live on odors only.

The vague disappointment grew into a positive rage. He felt instinctively that he could not reach the good things that the wonderful tree held within itself, but he persisted. He bent his back, uttered a growl of wrath just as a man swears, and fell to again with tooth and claw.

"If I didn't know that door was so very strong, I'd be afraid he'd get it," whispered Albert.

"Never fear," d.i.c.k whispered back with confidence.

The big wolf suddenly paused in his effort. Tooth and claw were still, and he crouched hard against the tree, as if he would have his body to blend with its shadow. A new odor had come to his nostrils. It did not come from the tree. Nor was it pleasant.

Instead, it told him of something hostile and powerful. He was big and strong himself, but this that came was bigger and stronger. The growl that had risen in his throat stopped at his teeth. A chill ran down his backbone and the hair upon it stood up. The great wolf was afraid, and he knew he was afraid.

"Look!" whispered Albert in rising excitement. "The wolf, too, is stealing away! He is scared by something!"

"And good cause he has to be scared," said d.i.c.k. "See what's coming!"

A great tawny beast stood for a moment at the edge of the clearing. He was crouched low against the ground, but his body was long and powerful, with ma.s.sive shoulders and fore arms. His eyes were yellow in the moonlight, and they stared straight at the Annex. The big wolf took one hasty frightened look and then fled silently in the other direction. He knew now that the treasures of the Annex were not for him.

"It's a cougar," whispered d.i.c.k, "and it must be the king of them all. Did you ever see such a whopper?"

The cougar came farther into the clearing. He was of great size, but he was a cat--a huge cat, but a cat, nevertheless--and like a cat he acted. He dragged his body along the earth, and his eyes, now yellow, now green, in the moonlight, were swung suspiciously from side to side. He felt all that the wolf had felt, but he was even more cunning and his approach was slower.

It was his habit to spring when close enough, but he saw nothing to spring at except a tree trunk, and so he still crept forward on noiseless pads.

"Now, what will Mr. Cougar do?" asked Albert.

"Just what the others have done," replied d.i.c.k. "He will scratch and bite harder because he is bigger and stronger, but we've fixed our Annex for just such attacks. It will keep him out."

d.i.c.k was right. The cougar or mountain lion behaved exactly as the others had done. He tore at the door, then he circled the tree two or three times, hunting in vain for an opening. Every vein in him was swollen with rage, and the yellowish-green eyes flared with anger.

"He'd be an ugly creature to meet just now," whispered d.i.c.k.

"He's so mad that I believe he'd attack an elephant."

"He's certainly in no good humor," replied d.i.c.k. "But look, Al!

See his tail drop between his legs! Now what under the moon is about to happen?"
