The Doctor drew the attention of his companions to the fact, that almost all these animals were beginning to lose their white winter dress, and would soon put on summer attire, while nature was already providing mosses, and poppies, and saxifragas, and short grass for their sustenance. A new world lay beneath that melting snow. But with these inoffensive animals came back their natural enemies. Foxes and wolves arrived in search of their prey, and dismal howls broke the silence of the short night. Arctic wolves closely resemble dogs, and their barking would deceive the most practised ears; even the canine race themselves have been deceived by it. Indeed, it seems as if the wily animals employed this ruse to attract the dogs, and make them their prey. Several navigators have mentioned the fact, and the Doctor's own experience confirmed it. Johnson took care not to let his Greenlanders loose; of Duk there was little fear; nothing could take him in. For about a fortnight hunting was the principal occupation. There was an abundant supply of fresh meat to be had. They shot partridges, ptarmigans, and snow ortolans, which are delicious eating. The hunters never went far from Fort Providence, for game was so plentiful that it seemed waiting their guns, and the whole bay presented an animated appearance. The thaw, meanwhile, was making rapid progress. The thermometer stood steadily at 32 deg. above zero, and the water ran down the mountain sides in cataracts, and dashed in torrents through the ravines. The Doctor lost no time in clearing about an acre of ground, in which he sowed the seeds of anti-scorbutic plants. He just had the pleasure of seeing tiny little green leaves begin to sprout, when the cold returned in full force. In a single night, the thermometer lost nearly 40 deg.; it went down to 8 deg. below zero. Everything was frozen--birds, quadrupeds, amphibia disappeared as if by magic; seal-holes reclosed, and the ice once more became hard as granite. The change was most striking; it occurred on the 18th of May, during the night. The Doctor was rather disappointed at having all his work to do again, but Hatteras bore the grievance most unphilosophically, as it interfered with all his plans of speedy departure. [Illustration: ] "Do you think we shall have a long spell of this weather, Mr. Clawbonny?" asked Johnson. "No, my friend, I don't; it is a last blow from the cold. You see these are his dominions, and he won't be driven out without making some resistance." "He can defend himself pretty well," said Bell, rubbing his face. "Yes; but I ought to have waited, and not have wasted my seed like an ignoramus; and all the more as I could, if necessary, have made them sprout by the kitchen stoves." "But do you mean to say," asked Altamont, "that you might have anticipated the sudden change?"
