The third evening after the departure of the captain's party David was sitting in the cook-tent watching the last embers of the sunset and the varying lights and shadows on the river. Shep stood near the edge of the bluff.

Suddenly the dog's ears pointed forward attentively and his whole body quivered. It was clear that something unusual had come in sight. No sooner had David reached the brow of the bluff than he saw the cause of Shep's excitement. A black animal was lapping the water where the river curved to the northwest, about three hundred feet distant.

The semi-darkness and the heavy mosquito net over his face prevented David from seeing clearly, but he instantly formed the conclusion that it was a dog belonging to some pack train on the neighboring trail, and whistled to see what it would do.

On hearing the whistle the animal raised its head, gazed a moment at the two figures on the bluff, resumed its drinking, and then, having satisfied its thirst, turned and started up the slope. As it did so, David was conscious[280] that it had a slinking gait unlike that of a dog, and for the first time he thought how queer it was that Shep had not offered to run down and make friends with the stranger.

"It's a small black bear," flashed into his mind. Instantly he ran with all speed to the cabin for the shot-gun, which he kept loaded with buckshot. The captain's party had carried off the only rifle, and David was now sorry he had not brought his own. He caught up the shot-gun, however, and slipping a few extra cartridges into his pocket, ran back to the bluff where Shep stood guard.

The strange animal had disappeared.

For a moment David was disconcerted. He had not thought the bear could get away so quickly, nor could he be sure whether it had gone into the fringe of trees and bushes along the river-bank or continued up the slope. He hesitated, too, before setting out to attack such an animal with only a shot-gun for a weapon and a dog of doubtful courage as an ally. The next instant, however, he had decided to track and kill the beast if possible, and calling Shep to follow, he hurried down to the river's sandy brink to examine the tracks by the waning light. He was quite puzzled at finding that they were almost identical in appearance with those made by Shep, but at length the truth dawned upon him. He had to deal, not with a young bear, but with a full-grown wolf!

[281]

He now endeavored to make Shep take the scent, but Shep was not trained to such work and sniffed around indiscriminately without attempting to follow the animal's trail. There was nothing for it but to track the wolf himself. He accordingly traced every track as far as it would lead him. One proceeded from the fringe of bushes to the point where the animal drank, while another led straight up the face of the bluff. The latter he followed as far as the sand continued; but the top of the elevation was grassy, and in the growing darkness the trail was quickly lost. Keeping his eyes and ears alert for the slightest sound, David penetrated some distance into the open woods, but without discovering further signs of the animal. Satisfied that nothing more could be done, he returned to camp, and took unusual pains to fasten the frail cabin door securely when he turned in for the night.

Nor was he destined to sleep without an alarm. A noise of rattling tin awoke him with a start. The interior of the cabin was quite dark, since, as we have said, there were no windows; but the nights were not yet without some light, and feeble rays outlined every chink as David sat up, threw off his mosquito net, and looked around. Again came the rattle of tin. It evidently proceeded from a pile of empty cans just outside the cabin. He brought himself to a kneeling posture and pressed his face close to one of the widest[282] chinks. Presently he distinguished an animal nosing among the cans and making the noise which had awakened him. It was Shep. David spoke to the dog, and having seen him walk away with a somewhat shame-faced air, he settled himself once more among the blankets and was soon asleep again.

Seven days had passed when the monotony of his existence was broken by the arrival of strangers. It was in the afternoon that he heard voices and the sound of horses from the direction of the trail, and a minute later saw two young fellows ride up, followed by a dozen pack animals.

"Hello!" exclaimed the foremost rider as he saw David, "this place has changed hands, I guess, since we was here last. How d'you do? Hovey and Herrick gone away?"

"Yes," answered David. "They left for the Kah Sha River a week ago. You've been here before?"

"Oh, yes! We're packing back and forth between Pyramid Harbor and Five Finger Rapids for the owner of these horses. We always like to put up here for the night, for it's pretty lonesome on this trail."

"That's so," said David, feelingly. He, too, was not a little pleased at the thought of company, and the more so in the present instance, because the new-comers were near his own age. The elder was slender, with dark hair and a rather sparse growth of beard, and might[283] have been twenty-two or three, while the other was a ruddy, plump lad of about seventeen.

"My name's Close," said the dark-haired one, as he dismounted and proceeded to unsaddle his horse. "We're from Wisconsin."

In return for this information David gave his own name and residence.

The Wisconsin boys took the packs from their horses and turned them loose to graze.

"Now for supper," said Close.

"You'll find a stove and dishes and a table, such as it is, in the cook-tent yonder," said David, hospitably. "I guess you know your way around. Just make yourselves at home, and I'll have the fire going in a jiffy."

It took the strangers but a short time to cook their evening meal, and as soon as they had finished with the stove David prepared his own supper, and the three sat down together.

"Can you spare us enough butter for our bread?" asked Close. "We're all out."

"Yes," said David, passing it over, "help yourself." He knew there were but two more cans in the cache under his charge, but he felt certain the captain would wish him to extend such hospitalities as lay in his power; and he would much rather have gone without butter himself for a time than deny it to hi............
