William Spiers Bruce, Polar Exploration (1911)
“ The reindeer proves most valuable nutriment for Arctic explorers, and Eskimo, and other Arctic tribes; and, like the musk-ox, has constantly furthered Arctic exploration, not only as a valuable food supply, but also because its skin is one of the most useful articles of clothing. Reindeer-skin sleeping-sacks have been an almost indispensable part of the equipment of Arctic and Antarctic explorers; the skin of the young reindeer is suitable for various articles of clothing. ”
