As he struck it, the water spurted through the holes in the boat, and a shrill cackling laugh came from the row of slant-eyed faces peering down over the rail. The little craft was by now a quarter full of water, and as the Japanese yacht took on speed and swung away on its course Bert started bailing desperately. He realized that there was hardly one chance in a thousand of his being picked up before, in spite of all he could do, the little boat would fill with water and sink.

However, he resolved to keep afloat as long as he could on the bare chance of some vessel passing in his neighborhood. Accordingly he set to work with the wooden scoop, sending sheet after sheet over the side. He worked desperately, and at first almost thought that he was gaining on the incoming water. His exertions were excessive, and before long he was forced to bail more slowly. He kept watching a deep scratch in the side of the boat to see if the water was gaining. With a sinking heart he realized that it was. In spite of all he could do, it crept up and up until finally it was over the scratch and the boat was nearly half full. Luckily for him, the sea was unusually calm, or he must soon have been swamped.

At the thought of all that it would mean to his country if he drowned with his secret, Bert fell to with the scoop with furious energy, but was not able to hold his terrible pace long, and finally flung down the bailer in despair.

"Perhaps I can plug up the holes," he thought, and ripped off his coat. He tore great pieces from it and tried to stuff up the holes, but to no effect. Such crude plugs as he could make were inadequate to stay the inrush of water, and he would hardly have time to insert one in one opening before that in another gave way.

So he was forced to give up this plan, and had recourse once more to the bailer. His only hope now was to keep afloat until he might be seen and picked up by a passing boat. He strained his eyes over the surrounding sea, but there was no sign of help in sight.

Slowly but surely the water crept up the sides of the boat until it was only a few inches from the gunwales. As the boat sank deeper, the water rushed in with ever-increasing force, and finally the conviction was forced in upon Bert that he had really come to the end of his resources. Of course, even after the boat sank, he could swim a little while, but after his fierce fight on the deck of the Japanese yacht and his terrific exertions afterward, he knew he would have little strength left.

Nevertheless he stripped off his outer clothing and resolved to do the best he could. Suddenly he was startled by a splashing, gurgling noise behind him, and, looking around, was surprised and puzzled to see what looked like the back of a huge whale floating within fifty feet of the stern of his little craft. In a second he understood, and a great wave of joy surged over him.

"It's a submarine," he thought, "and an American one at that," as he recognized the design.

Even as he looked, a hatch was thrown open in the deck of the submarine, and the head and shoulders of a man emerged from the aperture. Almost at the same instant Bert's rowboat gave a gentle lurch and disappeared beneath the surface. As he felt it sinking, Bert gave a great shout, and the man on the submarine whirled around in his direction, surprise written large on his countenance.

"By thunder!" he exclaimed, "what in the name of—" But here he dived below and in a few seconds reappeared with a life preserver attached to a long cord. This he cast toward Bert, who in the meantime had been swimming steadily toward the submarine. Bert grasped the preserver and was rapidly drawn on board by the first man who had appeared, and by two others who by now had joined him. Bert was soon safe on the sloping deck, and was besieged by a thousand questions.
