Jack glanced at it. "Why, we are running due south!"

"Aye; and I expect we have been two or three times round the compass already. That is what makes this frightful broken sea."

"Well, as long as we keep on running round and round," Jack said, "there is no fear of our running against the land anywhere."

Jim was further advanced in the study of navigation. "You forget," he said, "the centre of the cyclone is moving along all the time, and though we may go round and round the centre, we are still moving in the same direction as the cyclone is going, whatever that may be."

For hours the storm raged without the slightest signs of abatement. The sea was now terrific; the waist of the ship was full of water. Green seas swept over the vessel's bows, carrying everything before them; and pouring aft burst open the cabin door and deluged the cabin. By turns the boys made their way to the door and looked out.

"Come out, you fellows!" Jim Tucker shouted after one of these trips of investigation. "The men are coming out from the fo'castle. There is something to be done."

The boys came out and crawled a few steps up the poop-ladder, holding on for life as they did so. They did not attempt to get on to the poop, for they felt they would be blown away if they exposed themselves there to the full force of the wind.

Looking round, the scene was terrible. The surface of the sea was almost hidden by the clouds of spray blown from the heads of the waves; a sky that was inky black hung overhead. The sea, save for the white heads, was of similar hue, but ahead there seemed a gleam of light. Jim Tucker, holding on by the rail, raised himself two or three feet higher to have a better view. A moment was sufficient.

He sprang down again and shouted in his comrades' ears, "Breakers ahead!" It needed no further words. The light ahead was the gleam of a sea of white foam towards which the vessel was hurrying. Nothing could be done to check or change her course. Had the mizzen been standing an effort might have been made to show a little sail upon it, and bring her head up into the wind to anchor; but even could this have been done the cables would have snapped like pack-threads. There was nothing for it but destruction. Jack followed Jim's example—crawled to the top of the gangway, and holding on by the poop-rail raised himself to his feet and looked forward.

Right across their bows stretched a band of white breakers, and beyond through the mist he could make out the line of a low shore. The lads descended again into the waist, and with great difficulty made their way forward to where the men were huddled together round the entrance to the fo'castle. They too had kept a look-out, and knew of the danger into which they were running and the impossibility of avoiding it.
