The Schweder boys spoke of Arctic Hares (_Lepus arcticus andersoni_) being in the habit of eating the stomach contents of Caribou after the animals have been dressed in the field. This represents merely harmless utilization of a normally waste product, although it serves some of the natives as _nerrooks_ or “Eskimo salad” (_cf._ Richardson, 1829: 245). Wolverines, Mink, Weasels, and Lemmings help to consume unprotected caribou bodies. (In the Old World the Wolverine is regarded as a serious enemy of live Reindeer [Jacobi, 1931: 243; Harper, 1945: 473].) _References._--Pike, 1917 (1892): 56-58; Seton, 1911: 252, 1929, +2+: 413, 424, 443, and 1929, +3+: 108; Harper, 1932: 23; Ingstad, 1933: 157-159; Freuchen, 1935: 93, 99; Hoffman, 1949: 12; Banfield, 1951a: 36, 41; Harper, 1953: 40, 41. _Relations to flies_ Flies of various kinds perhaps cause more wide-spread, year-round misery to the Caribou than all other pests and enemies combined. It is safe to say that not a single individual in the whole population escapes their attacks, and some even succumb to mosquitoes (Gavin, 1945: 228). The various biting and parasitic flies have already been discussed to some extent in the section on _Influence of insects on distribution_. Harassment by these pests is believed to be the leading cause of the haste with which the Caribou are frequently seen passing over the Barrens in summer. Downes (1943: 204) has commented on the habit of Chipewyan hunters in the Nueltin Lake region of examining the legs of Caribou for swellings caused by mosquito bites. In a buck secured on August 17 the legs exhibited numerous little bumps of this sort; furthermore, black flies covered the buck’s body, while scarcely troubling those of us who were preparing the specimen. Fortunately the suffering from mosquitoes and black flies on the Barrens is largely limited to the months of July and August.
