During the winter months the seals do not come out upon the ice, and are then hunted usually with dogs that are trained for the purpose. The hunter, equipped with his spear-shaft in his hand, and his line, with the barbed spear-head attached, thrown over his shoulder, starts out, leading his dog, whose harness is on and the trace wound several times around his neck, so that but a yard or two is left to trail along the snow. When they reach the wide stretch of smooth ice that usually lines the shore in these regions, the dog is allowed to work to windward, and when his sensitive nostrils are saluted with the scent of a seal he indicates the fact by the excited manner in which he endeavors to reach the spot from which the odor emanates. The hunter restrains the dog's ardor, but follows his guidance until the spot is found at which the seal's blow-hole is situated. Often it is entirely covered with snow, but sometimes a small hole about an inch in diameter is seen. The blow-hole is a spot to which the seal resorts to get an occasional puff of fresh air, and here the hunter awaits him in order to secure him for the larder. When first found, the hunter merely marks the spot for a future visit by building around it a wall of snow blocks to cut off the wind, and making a seat of similar material upon which to rest while waiting for the blow. This is the tedious proceeding in the life of an Esquimau, or at least would be for a civilized person so situated. Sometimes the seal comes up within half an hour or an hour, but often the hunter stands or sits by the hole all night long, and sometimes for a day or two. I have heard of instances in which they sat for two days and a half waiting for the seal to put in an appearance. In fact, Papa told me that he once sat for three days at one seal hole, and then it did not come up. During all this time the hunter must keep perfectly still--that is, he must not walk around or move his feet off the ice. He can move his body to keep up a circulation of the blood, or move his feet inside his stockings if they are sufficiently loose to allow of such motion, but no noise must occur which would alarm the game if in the vicinity of the hunter.
