He glanced over his shoulder, and there was the bear appearing to shuffle along clumsily, but getting over the ground at a great rate of speed, which told the lad that he need do his best; but he consoled himself with the belief that, unless terribly hungry, the bear would not follow him for long; on the other hand, if famished, it would keep on and tire him out, and then-- Steve obstinately refused to let his imagination carry him any farther-- the thoughts were too horrible; and, mentally vowing that if he managed to get clear away he would never feel any compunction in helping to shoot a bear again, but would do his best to become the owner of its rich, whitish fur, he tore on as hard as he could go, fully conscious of the fact that the bear, though some yards behind, was determined to tire him out and run him down. The way now became more open, and as he raced on he just glanced at the opening to the narrow ravine on his right, for there was no temptation to leave the broad, open way for a stone-encumbered defile. No temptation then; but the next moment there was, for he was not far past enjoying the satisfaction of distancing his pursuer, when his heart sank, and a curdling sensation of horror so convulsed him that he dropped his cap, and pressed his hands to his throat; for there, fifty yards in front, and coming toward him, was a second bear, into whose jaws he was running hard. Danger behind, danger before, and between them death without mercy. There was only one way out of the peril, and that was to run back and turn up the narrow defile. It was a desperate venture, for the first bear was lumbering along and had nearly reached the turning; in fact, would have passed it before the boy could reach the haven of comparative safety if it had not stopped suddenly in surprise at seeing the quarry so suddenly turn round and seem to charge. Instead, then, of running to meet him, the bear suddenly raised itself up, and, with outstretched claws, awaited Steve's approach. It was all over in a moment or two: the boy had to go so close to the waiting bear that the beast struck at him with its right paw, and nearly touched the boy's shoulder; but the next instant he was beyond reach, and running up the defile. There was no bounding over the ground, though, here, for the place was, as has been shown, encumbered with fallen blocks; and Steve's heart, which the moment before rose with a leap at the way in which he had eluded the bears, sank once more like lead, for he knew enough of the natural history of these beasts and their construction to feel that, though they had left the ice for a prowl among the rocks, they would be thoroughly at home over such ground as he was traversing. "I've only put it off for a bit," he said to himself; "and they'll run me down." This thought only roused him.
