Both otter and arrow had disappeared, but the Aleut sat waiting grimly, although the boys in the other boat gave a yell of exultation. In a few moments the wounded animal showed a hundred fathoms ahead. Here, stung by the pain of the bone head, which had sunk deep into its back, it swam confusedly for a moment at the surface. The shaft of the arrow had now been detached from the loose head cunningly contrived by the native arrow-makers, and a long cord, which attached the arrow-head to the shaft, and which was wound around the latter, now unreeled and left the shaft floating, telltale evidence of the otter's whereabouts, even when it dived. [Illustration: BOTH OTTER AND ARROW HAD DISAPPEARED, BUT THE ALEUT SAT WAITING GRIMLY] Jimmy tried a long shot as the bidarka swept ahead under Rob's paddle, but this time he missed, and down went the otter again. It did not dive deep, however, and the shaft of the arrow told where it might be expected. As its round head, with bright, staring eyes, thrust up above the water, there came the twang of the young Aleut's bow, and the second arrow chugged into the body of the otter. Even the older hunter greeted this shot with applause. The otter, however, is hard to kill with an arrow of this sort, since its skin is loose and tough. The creature dived once more, but the second floating shaft now began to handicap its motions. Both boats followed it from place to place as it swam. At last, almost exhausted, it showed once more, and the older Aleut sent home an arrow at the back of its head which killed it at once. He hauled up across the bidarka deck the body of the otter, a dark-brown creature, even at that season fairly well furred, and in weight about that of a good-sized dog. Now and again calling out in sheer exultation at the success of this strange hunt, they all now turned ashore. That day they had plenty to do in skinning the otter and making a rude stretching-board for the great skin. The boys were all astonished to see how much larger it stretched than had seemed possible from the size of the body of the animal itself; but the hide of the sea-otter lies in loose wrinkles, so that it may bend and turn freely as a snake when making its way in the water. They found the skin to be more than six feet long from tip to tip. The young friends engaged in some speculation as to how much the skin might bring at the Seattle market. One thing of value it seemed to establish beyond doubt--Jimmy and Skookie, as they both worked at fleshing the hide, had dropped their mutual suspicions and become hunting companions. XXIX UNCERTAINTY
