noon
Every hour added to Rod 's knowledge of the wilderness and its people . For the first time in his life he saw the big dog-like tracks made by wolves , the dainty hoof-prints of the red deer and the spreading imprints of a traveling lynx ; he pictured the hugeness of the moose that made a track as big as his head , discovered how to tell the difference between the hoof-print of a small moose and a big caribou , and in almost every mile learned something new . Half a dozen times during the morning the hunters stopped to rest . By noon Wabi figured that they had traveled twenty miles , and , although very tired , Rod declared that he was still `` game for another ten . '' After dinner the aspect of the country changed . The river which they had been following became narrower and was so swift in places that it rushed tumultuously between its frozen edges . Forest-clad hills , huge boulders and masses of rock now began to mingle again with the bottoms , which in this country are known as plains .
