“I hae ma doots,” said Don, “if that is a mosquito I killed just noo. I think it was some new kind of night bird.”

How long he had been asleep Jack did not know, when he was aroused by the growling of the two dogs on the shore, and crawled out from under the tarpaulin. The night was clear, and there was a fine starlight. In the East there was the faintest glimmer of dawn. The fire on shore had died down, but the embers still shone. The Indian who had been on watch had risen from his seat and followed the dogs, which had run growling up the strip of sand toward the meadow which lay between the water and the woods. Evidently there was some game in sight, and Jack crawled back under the tarpaulin and grasped his rifle, a Remington repeater. He did not arouse any of the others as he had really seen nothing, and was a little sensitive to possible ridicule.

He ran up the gangplank and stepped ashore. The other Indians were still asleep and Jack took the trail of the sentinel, whom he could dimly see in the distance.

The latter turned as he heard Jack’s footsteps on the gravel, and waited for him.

“What is it?” asked Jack.

“No know,” replied the Indian, “maybe bear, dogs no fight, only growl.”

Dimly through the dawn Jack could make out a black mass lumbering slowly down through the meadow toward them. The dogs ran around it in circles, merely growling and offering no attack. At a word from the Indian, however, they ran in snarling on the animal, which stopped, and with a loud “woof” reared up on its haunches, showing an enormous height.

“Bear; shootum,” cried the Indian, who had only an ax with him. Jack raised his rifle and fired, and as the bear dropped on all fours fired another shot.

The animal let out a snarling cry, and, grasping one of the dogs which had ventured within reach of its enormous paws, squeezed the life out of it before it could let out a cry. The Indian gave a yell and ran in on the enormous animal, and with a well-directed blow of the ax split its skull open between the eyes. At the same time Jack, as a precaution, fired another shot into the creature’s open mouth, and it rolled motionless on its side.

The shots and the cries of the Indian had aroused every one on the two boats, and Swiftwater and Skookum Joe came running over the sands, rifles in hand. By this time the early dawn of the high latitude had rendered all objects visible, and the boys had also joined Jack and the Indian, who was circling cautiously around the huge brute, trying to ascertain the fate of the dog, which was still clasped in the death clutch of the now motionless animal.
