four o'clock
In the afternoon of the second day Thor stopped in a dump of jackpines under which the ground was strewn with fallen needles . He began to eat these needles . They did not look good to Muskwa , but something told the cub that he should do as Thor was doing ; so he licked them up and swallowed them , not knowing that it was nature 's last preparation for his long sleep . It was four o'clock when they came to the mouth of the deep cavern in which Thor was born , and here again Thor paused , sniffing up and down the wind , and waiting for nothing in particular . It was growing dark . A wailing storm hung over the canyon . Biting winds swept down from the peaks , and the sky was black and full of snow .
