From this bladder-dart the Eskimo's principal hunting-weapon—the ingenious harpoon with bladder and line—has probably developed. In order to cope with the larger marine animals, the size of the bladder was doubtless gradually increased; but the disadvantage of this—the fact that it offered too much resistance to the air to be thrown far and with force—must soon have been felt. The bladder was then separated from the javelin, and only attached to its point by means of a long and strong line, the harpoon-line. The harpoon, which was now made larger and heavier than the original javelin, was henceforward thrown by itself, but drawing the line after it. The bladder, fastened to the other end of the line, remained in the kaiak until the
