There they are hunted in boats, or when the wind is from such a direction as to keep the pack on to the floe they can be successfully hunted on foot. The method of hunting is precisely the same as that already described in reference to hunting seal, except that the spear is generally used in preference to the rifle to secure the walrus, and the rifle is preferred to the spear in seal-hunting. Usually there are two hunters who approach the walrus, one hiding behind the other, so that the two appear but as one. When the spear is thrown, both hold on to the line, which is wound around their arms so as to cause as much friction as possible, in order to exhaust the animal speedily. The spear-head is of walrus tusk, and is about three inches long and three-quarters of an inch thick, with an iron barb that is kept very sharp. The line is attached to the middle of the spear-head, the near end being slanted, so that when the line is tightened it lies cross-wise in the wound, like a harpoon, and it is almost impossible for it to draw out after once passing through the tough hide of the animal. When the line is nearly run out, the end of the spear-shaft is passed through a loop in the end of the line and held firmly by digging a little hole in the ice for the end of the spear to rest in, the foot resting upon the line and against the spear to steady it. This gives the hunter an immense advantage over his powerful game, and if he is fortunate enough to secure this hold, there is no escape for the walrus except that the line may cut on the edge of the sharp ice, or the thin ice break off, and hunter, line, and all be precipitated into the water--a not unusual experience in walrus hunting. Another cause of misfortune is for the line to become entangled around the arm of the hunter, so that he cannot cast it off, in which case he is most assuredly drawn into the sea, and in nine cases out of ten drowned, for his knife is seldom at hand for an emergency, and no amount of experience will ever induce an Inuit to provide against danger. Sometimes the hunter is alone when he strikes a walrus, and in that case it requires considerable dexterity to secure the spear hold in the ice; or if he fails to get that he may sit down and brace his feet against a small hummock, when it comes to a sheer contest of muscle between the hunter and the walrus. In these contests victory generally perches upon the banner of the walrus, though the Inuit will never give up until the last extremity is reached. Often he is dragged to the very edge of the ice before he finds a protuberance against which to brace his feet, and often he is drawn down under the ice before he will relinquish his hold. He is very tenacious under such circumstances, for he knows that when he loses the walrus he loses his line and harpoon also.
