R M Ballantyne: The World of Ice (Illustrated)
The stores, in order to relieve the strain on the ship, were removed to Store Island, and snugly housed under the tent erected there, and then a thick bank of snow was heaped up round it. After this was accomplished, all the boats were hauled up beside the tent, and covered with snow, except the two quarter-boats, which were left hanging at the davits all winter. When the thermometer fell below zero, it was found that the vapours below, and the breath of the men, condensed on the beams of the lower deck and in the cabin near the hatchway. It was therefore resolved to convert some sheet-iron, which they fortunately possessed, into pipes, which, being conducted from the cooking-stove through the length of the ship, served in some degree to raise the temperature and ventilate the cabins.
