This was the case with the lemon-juice which Sir John Ross found among the stores of the _Fury_. An anti-scorbutic effect has been attributed also—and with justice—to the chewing of tobacco. It appears that liability to scurvy is very different among different races, and that neither vegetable nor animal food is an absolute preservative. The Eskimos, and even the Lapps, who seldom or never use vegetables, are almost exempt from it, and McClure’s men fell down with it in their second winter, although they had fresh meat three times a week. Steller relates that in Kamschatka scurvy attacks strangers only, but not the natives, who live largely on vegetables; he states also, that the scurvy when it does appear among strangers and visitors there, is cured by a diet of the fresh fish of spring. CHAPTER XIV. SUNRISE OF 1874. 1. An unbroken sleep for the whole winter would, undoubtedly, be a blessing to the Arctic navigator, and the most energetic among us resigned himself to slumber for a few hours in the afternoon—the profane time of the day for all zones of the earth—especially after the coming in of the New Year, when the long unbroken night is intensely felt. The darkness diminished very gradually, and as the weather was frequently cloudy and dull, it was little lessened by the full moon, which we had at the beginning of January and February. December 26, we were able to read only the title of _New Free Press_, at the distance of a few inches, but not a word of Vogt’s _Geology_. January 11, the word Geology on the title of that book was discernible in clear weather, but only when the book was held up to the light of the midday twilight. On the following day it was as dark at nine o’clock in the morning as at noon on December 1st. The moon returned again on the 24th of January, and after it was four days old we could distinguish the common print of the “Press” by its light, and for the first time read off the degrees of the thermometer without artificial means. During the whole of the month we had alternations of high temperatures and snow-drifting, and at the end of it the wind dropped and the cold became exceedingly great, causing the ice to break up to the south of our position. It would be difficult to give in an illustration any notion of the wonderful forms produced by the twilight, and its glowing colour-effects, and quite impossible to describe the blaze of the meridian heavens, while deep shadows still lay over the ice-plains and a dark ridge fringed and closed the horizon.
