“Between tea and supper the sledge-drivers went out to attend and feed their dogs, which were always tied up for the night, lest they should be tempted away by the scent of some wild animal. Meanwhile, we were engaged in comparing our observations, and in laying down on the map the ground which we had gone over in the course of the day; the severe cold, and the smoke which usually filled the tent, sometimes made this no easy task. Supper always consisted of a single dish of fish or meat soup, which was boiled for us all in the same kettle, out of which it was eaten. Soon after we had finished our meal, the whole party lay down to sleep. On account of the cold we could not lay aside any part of our travelling-dress, but we regularly changed our boots and stockings every evening, and hung those we had taken off, with our fur caps and gloves, on the tent-poles to dry. This is an essential precaution, particularly in respect to stockings, for with damp clothing there is the greatest risk of the part being frozen. We always spread the bear-skins between the frozen ground and ourselves, and the fur coverings over us, and, being well tired, we usually slept very soundly. As long as all the sledge-drivers continued with us, we were so crowded that we had to place ourselves like the spokes of a wheel, with our feet towards the fire and our heads against the tent wall. In the morning we generally rose at six, lit the fire, and washed ourselves before it with fresh snow; we then took tea, and immediately afterwards dinner (which was similar to the supper of the night before). The tent was then struck, and every thing packed and stowed on the sledges, and at nine we usually took our departure.” The chief impediments to journeying on the ice were found to be the hummocks, often eighty feet high, which lie in ridges at certain distances, parallel perhaps to the shore. Along the line or lines where the ice is periodically broken, it is forced by pressure and the tossing of a tempestuous sea into those irregular ridges through which Wrangell had sometimes to make a way with crowbars for half a mile. The “polinyas,” or spaces of open water in the midst of the ice, offered less hindrance, as they might be avoided; but in this neighborhood, and sometimes even where no hole in the ice was visible, layers of salt were met with, which cut the dogs’ feet, and at the same time increased the labor of the draft, the sledges moving over the salt with as much difficulty as they would over gravel.
