In the absence of all restraint Tug's dogs crept toward the fire, and crouched within the radius of its pleasant warmth, their great muzzles resting between outstretched paws, their fierce eyes staring steadily at the ruddy flicker of the leaping flames. Maybe they were dreaming of those savage ancestors from whom they sprang; maybe memories of fierce battles, of gluttonous orgies, of desperate labors, were crowding pleasantly under the charm of the moment's ease. But twitching ears bespoke that curious canine alertness which is never relaxed.
The moments passed rapidly; moments of delight which rarely fall to the lot of the wolfish trail dog. It was an oasis of leisure in lives spent betwixt the labor of the trail and the settling of fierce quarrels, which, to the human mind, possess no apparent cause.
Then again, in the briefest of seconds, the whole scene was changed. It came as one of the dogs lifted its head gazing intently at the pile of furs under which the sick man lay.
It was a tense moment. Every muscle in the creature's powerful body was set quivering, and a strange, half pathetic, half savage whimper escaped its twitching nostrils. Every head about the fire was abruptly lifted, every ear was set pricked alertly, and each pair of fierce eyes stared hard in a similar direction.
There was no sign of movement among the furs, no change of any sort, nothing whatsoever to arouse such tense ferocity, even alarm. But those things were there in every eye, in the pose of each savage creature, in the slow rising of harsh manes until they bristled high upon every shoulder.
One dog rose to its feet.
Each dog rose slowly in turn; slowly and watchfully. And now a further change became apparent in their attitudes. All ferocity suddenly died out, leaving only alarm, a desperate, currish terror. Manes still bristled like the teeth of fine combs, but ears were flattened to lowered heads, and great whipping tails curled under, between crouching hind legs, while lifted lips left gleaming fangs displayed in currish snarls.
Yet the sick man's bed at which they stared still remained undisturbed. The man beneath the blankets had not stirred. He was still, so still. It was as if these brutish eyes beheld something invisible to the human eye; something which crushed their hearts under an overwhelming burden of fear.
For nearly a minute the statue-like tenseness of attitude remained. Then the spell was broken. One dog, the largest of all, the leader of the team, the oldest in the craft of the trail, oldest in years, and, possibly, far the oldest in canine wisdom, squatted upon its haunches and licked its lips. One by one the rest followed its example, and, finally, with sighs as of relief, they returned again to their luxurious basking in the firelight.
But the leader did not attempt to return to the charmed circle of the fire. It seemed as if he realized a sense of responsibility. Presently he rose, and, with gingerly tiptoeing, moved away from his companions. He edged warily toward the sick man's bed. He drew near, snuffing at the air, ready to draw back instantly should his wisdom so prompt him. Nearer and nearer he drew, and with lowered muzzle he snuffed at the edge of the bed. With stealthy, creeping gait he made his way toward the pillow, snuffing as he went. Then, as his greenish eyes rested upon the man's lolling head, he again squatted upon his haunches and licked his lips. The next moment a low whimper broke the silence. It grew louder. Finally the dog's great head was lifted, its muzzle was thrown high into the air, and the whimper was changed into a long-drawn-out howl of amazing piteousness. It was doling the death warning of its race.
