But in a short while his fear of the tepees passed away. He saw the women and children passing in and out of them without harm, and he saw the dogs trying often to get into them, and being driven away with sharp words and flying stones. After a time, he left Kiche’s side and crawled cautiously toward the wall of the nearest tepee. It was the curiosity of growth that urged him on—the necessity of learning and living and doing that brings experience. The last few inches to the wall of the tepee were crawled with painful slowness and precaution. The day’s events had prepared him for the unknown to manifest itself in most stupendous and unthinkable ways. At last his nose touched the canvas. He waited. Nothing happened. Then he smelled the strange fabric, saturated with the man-smell. He closed on the canvas with his teeth and gave a gentle tug. Nothing happened, though the adjacent portions of the tepee moved. He tugged harder. There was a greater movement. It was delightful. He tugged still harder, and repeatedly, until the whole tepee was in motion. Then the sharp cry of a squaw inside sent him scampering back to Kiche. But after that he was afraid no more of the looming bulks of the tepees. A moment later he was straying away again from his mother. Her stick was tied to a peg in the ground and she could not follow him. A part-grown puppy, somewhat larger and older than he, came toward him slowly, with ostentatious and belligerent importance. The puppy’s name, as White Fang was afterward to hear him called, was Lip-lip. He had had experience in puppy fights and was already something of a bully. Lip-lip was White Fang’s own kind, and, being only a puppy, did not seem dangerous; so White Fang prepared to meet him in a friendly spirit. But when the strangers walk became stiff-legged and his lips lifted clear of his teeth, White Fang stiffened too, and answered with lifted lips. They half circled about each other, tentatively, snarling and bristling. This lasted several minutes, and White Fang was beginning to enjoy it, as a sort of game. But suddenly, with remarkable swiftness, Lip-lip leaped in, delivering a slashing snap, and leaped away again. The snap had taken effect on the shoulder that had been hurt by the lynx and that was still sore deep down near the bone. The surprise and hurt of it brought a yelp out of White Fang; but the next moment, in a rush of anger, he was upon Lip-lip and snapping viciously. But Lip-lip had lived his life in camp and had fought many puppy fights. Three times, four times, and half a dozen times, his sharp little teeth scored on the newcomer, until White Fang, yelping shamelessly, fled to the protection of his mother. It was the first of the many fights he was to have with Lip-lip, for they were enemies from the start, born so, with natures destined perpetually to clash.
