The hillock was nearly half a mile away. Between it and the boat lay an almost level stretch of mud flats, covered for many inches by recently-fallen snow, and fifty yards of ice, now of course indistinguishable from the land. Could Yamaguchi reach the boat in time? He had the start of his pursuers, but they were mounted, and, as Bob now saw, there were eight of them. It was almost impossible that the runner could escape. Yet it seemed impossible to help him. The seamen in the boat had rifles, but now that pursuers and pursued had descended the declivity and come to the flat, a shot, however well aimed, might hit the man it was intended to assist. In one tense moment Bob seemed to live a lifetime. Then, with a cry to the men to remain where they were—which, not knowing English, they understood rather by the tone than by the words—he sprang over the side of the boat on to the ridge of ice. It creaked and sank under him, but he leapt on towards the shore, intent on assisting the flagging footsteps of the Japanese, who was evidently near the end of his endurance. The ice crackled and groaned as Bob raced on. He reached the softer snow, and his pace was checked; he heard a shot from one of the pursuing Cossacks ring past his ear; he shouted a word of encouragement to the panting lieutenant, and then, leaping, floundering, staggering over the intervening yards, he caught Yamaguchi by the arm and turned to run with him towards the boat, feeling all the time that theirs was a hopeless case, for the foremost horseman, distancing his comrades, was now but a dozen yards away. All at once a shot flashed from the boat. Bob heard a strange sobbing sigh behind him. A moment after he felt the impact of a heavy body, he was thrown violently on his face, and a riderless horse galloped madly on towards the sea.
