"They have got her!" Ben said. "Now then for the ship." For the first time since they entered the broken water they had leisure to look about them. Those on board the ship had lost no time, and had already launched a light spar with a line tied to it into the water. "It will miss us," Ben said, after watching the spar for a minute. "You see, I allowed for wind and tide, and the wind does not affect the spar, and the tide will sweep it down thirty or forty yards on our port bow." It turned out so. Those on board payed out the line until the spar floated abreast of the smack, but at a distance of some thirty yards away. "What is to be done?" Ben asked. "If we were to try to get up sail again we should drift away so far to leeward we should never be able to beat back." "Look here," Jack said; "if you signal to them to veer out some more rope I could soon do it. I could not swim across the tide now, but if it were twenty fathom further astern I could manage it." "You could never swim in that sea, Jack." "Well, I could try, uncle. Of course you would fasten a line round me, and if I cannot get there you will haul me in again. There cannot be any danger about that." So saying Jack at once proceeded to throw off his oil-skins and sea-boots, while Ben went to the bow of the boat and waved to those on the wreck to slack out more line. They soon understood him, and the spar was presently floating twenty yards further astern. Jack had by this time stripped. A strong line was now fastened round his body under his arms, and going up to the bow of the boat, so as to give himself as long a distance as possible to drift, he prepared for the swim. CHAPTER V. THE RESCUE. JACK was a good swimmer, but he had never swum in a sea like this. "If I raise my arms, uncle, pull in at once. If I see I cannot reach the spar I sha'n't exhaust myself by going on, but shall come back and take a fresh start. Let me have plenty of rope." "All right, Jack! we won't check you." Jack took a header, and swimming hard under water came up some distance from the boat. "He will do it," Tom shouted in Ben's ear. "He is nigh half-way between this and the rope already." It was, however, a more difficult task than it looked. Had the water been smooth it would have been easy for Jack to swim across the tide to the spar before he was swept below it, but he found at once that it was impossible to swim fast, so buffeted and tossed was he by the sea, while he was almost smothered by the spray carried by the wind to the top of the waves. He trod water for a moment with his back to the wind, took a deep breath, and then dived again. When he came up he was delighted to see that he was as near as possible in the line of the spar, which was towing but a few yards from him. He ceased swimming, and a moment later the tide swept him down upon it.
