"What vessel can this be? What is she doing so near the Pole?"
The Doctor and Bell only thought of going to the rescue of some poor fellows like themselves, or being rescued by them.
But before long they were engrossed enough with their own dangers and difficulties, for their situation became hourly more perilous.
Simpson was getting gradually worse, and the Doctor's practiced eye saw death rapidly approaching. He could do nothing for him; he was suffering acutely himself from ophthalmia, which might end in total blindness without care. The twilight was strong enough now to cause a glaring reflection on the snow which burnt the eyes. Spectacles would have been some protection, but it was impossible to wear them, as the glasses became encrusted with ice immediately, and consequently perfectly opaque, and yet it was necessary to keep a constant look-out to avoid accidents. This must be done at all risks, so Bell and the Doctor agreed to undertake the duty in turn, and bandage their eyes in the intervals.

Towards evening a violent tempest swept over the snowy ridges, and soon increased to such a hurricane, that they were forced to stop and lie down on the ground. But the temperature was so low that they would all inevitably have been frozen to death, had not Bell succeeded after much difficulty in making a snow hut, in which they took shelter and recruited themselves scantily with a few morsels of pemmican and some hot tea. There were only four gallons of spirits of wine now remaining, as it was not only used in making tea and coffee, but in getting water to drink, for it must not be imagined that snow can be employed to quench thirst without being melted. In temperate countries, where the thermometer is scarcely ever so low as freezing point, it might not be injurious, but beyond the polar circle it is quite a different matter. The snow there is so intensely cold, that one could no more lay hold of it with the naked hand than red-hot iron; consequently, there is such a difference of temperature between it and the stomach, that swal-
