This was evidently also the view of the captain, as two boats were lowered and anchors got into them. But it is no easy matter to row a boat with a heavy weight in it against wind and tide; and before they had got fairly away from the vessel she had already swung round a considerable distance, and was heeling over a good deal from the force of the wind and tide. It was nearly half an hour before the boats were far enough off to get the anchors over with any effect.

"They won't dare to haul on them now," Joe said. "They would only come home. Those anchors ain't heavy enough to work her stern round. I expect when a tug comes along they will get them to help, else she will keep on driving higher and higher."

"Hallo!" The exclamation came from Jack, who now happened to look round towards the boat. They had accidentally taken their stand on the highest point of the sand-bank, and in watching the steamer had forgotten all about the tide, which, under the influence of a north-east wind, had risen with great rapidity. The patch of dry sand was scarcely fifteen yards wide, and would be entirely covered in a very few minutes.

"Look, Bill, the boat has gone!"

It was true. The grapnel, a very light one, with a short length of rope, had been thrown carelessly down on the sand when they last hauled the boat up, and as the full strength of the tide had caught the boat, it had dragged a considerable distance, and was drifting away up the Ray.

"What is to be done?" Joe exclaimed.

"Do you think we could wade along to the island, Bill?" Jack asked.

Bill shook his head. "No; there are deep channels where it would be over our heads. I can't swim a stroke, no more can Joe."

"Shall I swim to the boat, Bill, and try and get her back?"

Joe shook his head. "She is in deep water now, Jack, and the grapnel ain't holding her a bit; she will drift as fast as you can swim. But of course you can try if you like, it don't make any difference to us, for you could never beat back against this wind and tide. What fools we have been, to be sure!"
