The thaw, meanwhile, was making rapid progress. The thermometer stood steadily at 32° 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°; it went down to 8° 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.

"But do you mean to say," asked Altamont, "that you might have anticipated the sudden change?"
