In order to gain once more upon the pursuit and give himself a chance to rest later on, he increased his speed greatly and also took precautions to hide his trail, which was not difficult where there were so many little streams. When he stopped about midnight he believed that he was at least ten or twelve miles ahead of the nearest warriors, who must have lost a great deal of time looking for his traces; and, secure in the belief, he crept into a thicket, drew about him the blanket and the buffalo robe, which were now sufficient, and slept soundly until he was awakened by the howling of wolves. He was quite able to tell the difference between the voices of real wolves and the imitation of the Indians, and he knew that these were real. He raised up a little and listened. The long, whining yelp came again and again, and he was somewhat surprised. He concluded at last that the wolves, driven hard by hunger, were hunting assiduously in large packs. When mad for food they would attack man, but Henry anticipated no danger. He felt himself too good a friend of the animals just then to be molested by any of them, and he went back to sleep. When he awoke again just before dawn he heard the wolves still howling, but much nearer, and he thought it possible that they had been driven ahead by the Indian forces. If so, it betokened a pursuit rather swifter than he had expected, and, girding himself afresh, he fled once more before the sun was fairly up. It was the usual rolling country that lies immediately south of the Great Lakes, forested heavily then and cut by innumerable streams, great and small. The creeks and brooks were not swollen as much as those farther south, and Henry judged from the fact that here also the snowstorm had not passed. Nevertheless, he crossed many muddy reaches and he was compelled to ford two or three creeks the water of which reached to his knees. But his moccasins and leggings dried again as he ran on, and he was not troubled greatly by the cold. It was a country that should abound in game, but no deer started up from his path, no wild turkeys gobbled among the boughs, and the little prairies that he crossed were bare of buffaloes. He assumed at once that it had been hunted over so thoroughly by the Indians that the surviving game had moved on. When the warriors found a new hunting ground it would come back and increase. He believed now that this accounted for the howling of the wolves deprived of their food supply and perhaps not yet finding where it had gone. He maintained a rapid pace, and his wet leggings and moccasins dried gradually. The morning was frosty and cold, but wonderfully brilliant with sunlight, and here, where the forest had been free from snow, it glowed in autumnal colors.
