In illustration of the primary importance of the Caribou to both primitive and civilized man in the Arctic and the sub-Arctic, the numerous cases of partial or complete starvation in the absence of Caribou may be cited. The chronicles of northern explorers are replete with them. A notable case is that of John Hornby and his two companions on the Thelon River in the winter of 1926-27 (Hoare, 1930: 25; Christian, 1937). In the autumn of 1946 only a small fraction of the normal caribou migration passed by the Eskimo camps on the upper Kazan River. These happy-go-lucky, utterly improvident people did not take steps to secure an alternative winter’s supply of fish, and by the following spring eight out of the band of 27 persons had succumbed directly or indirectly to starvation. (It is suspected that several were accounted for by anthropophagy.) Women, children, and dogs were the victims; no adult male succumbed. The casualties would doubtless have been more numerous if Charles Schweder had not reported the plight of the band when he made a trip to Reindeer Lake in March. Thereupon the government shipped emergency rations by plane as far as Nueltin Lake, and Charles transported them from that point by sleigh to the Kazan. Meanwhile he rescued two of the orphan children, took them to the Windy River post, and in a few more months formally adopted them. _Ethnological material from caribou products_ In addition to the utilization of caribou products for the primary purposes of food, clothing, and shelter, as discussed in preceding pages, certain other uses of an ethnological nature may be mentioned here. Charles Schweder spoke of the former Eskimo use of splint bones from the legs of Caribou as needles, after a hole had been drilled or burned through the larger end. They are about the same length as a large darning needle. These people commonly use the back sinew as thread or as wrapping on tools, drums, and the like. I saw a piece of back sinew being dried for future use at the Windy River post. Either lard or caribou fat serves as fuel for an “Eskimo candle”; the wick is a bit of rag or moss. The heat of the flame melts the fat where it is spread out in some small receptacle like a can cover. When our other means of illumination gave out at the Windy River post, I worked or wrote notes for many hours by the light of one of these candles. It gives approximately as much illumination as an ordinary tallow candle. One disadvantage of using caribou fat for this purpose is the considerable amount of smoke that it produces.
