Hatteras and his companions were clothed in skins more useful than elegant. Their heads and faces were covered with hoods, their mouths, eyes, and noses alone coming into contact with the air. If they had not been exposed the breath would have frozen their coverings, and they would have been obliged to take them off with the help of an axe--an awkward way of undressing. The interminable plain kept on with fatiguing monotony; icebergs of uniform aspect and hummocks whose irregularity ended by seeming always the same; blocks cast in the same mould, and icebergs between which tortuous valleys wound. The travellers spoke little, and marched on, compass in hand. It is painful to open one's mouth in such an atmosphere; sharp icicles form immediately between one's lips, and the breath is not warm enough to melt them. Bell's steps were marked in the soft ground, and they followed them attentively, certain of being able to go where he had been before. Numerous traces of bears and foxes crossed their path, but not an animal was seen that day. It would have been dangerous and useless to hunt them, as the sledge was sufficiently freighted. Generally in this sort of excursion travellers leave provision-stores along their route; they place them in hiding-places of snow, out of reach of animals; unload during the journey, and take up the provisions on their return. But Hatteras could not venture to do this on moveable ice-fields, and the uncertainty of the route made the return the same way exceedingly problematic. At noon Hatteras caused his little troop to halt under shelter of an ice-wall. Their breakfast consisted of pemmican and boiling tea; the latter beverage comforted the cold wayfarers. They set out again after an hour's rest. The first day they walked about twenty miles, and in the evening both men and dogs were exhausted. However, notwithstanding their fatigue, they were obliged to construct a snow-house in which to pass the night. It took about an hour and a half to build. Bell showed himself very skilful. The ice-blocks were cut out and placed above one another in the form of a dome; a large block at the top made the vault. Snow served for mortar and filled up the chinks. It soon hardened and made a single block of the entire structure. It was reached by a narrow opening, through which the doctor squeezed himself painfully, and the others followed him. The supper was rapidly prepared with spirits of wine. The interior temperature of the snow-house was bearable, as the wind which raged outside could not penetrate. When their repast, which was always the same, was over, they began to think of sleep. A mackintosh was spread over the floor and kept them from the damp. Their stockings and shoes were dried by the portable grate, and then three of the travellers wrapped themselves up in their blankets, leaving the fourth to keep watch; he watched over the common safety, and prevented the opening getting blocked up, for if it did they would
