At last he was free and struck upward as swiftly as possible. When it seemed that his lungs must burst for want of air, his head suddenly bobbed upon the surface. He gasped as he inhaled great breaths of the fresh air. A boat approached at that moment and he was drawn aboard, where he sank down. Jack, when he came up from below, had thought first of Frank. Rapidly he scanned the surface of the sea for some sign of his chum or of the wreckage. Seeing neither, he knew what had happened. Taking a deep breath he dived. It took the lad some time to locate the sinking mass of wreckage below and when he did come upon it there was no sign of Frank. Jack stayed below until he could stand it no more; then rose to the surface. There rough hands seized him and dragged him into a boat. In vain the lad struggled. He wanted to get loose so he could make another attempt to rescue his friend. "Frank!" he cried. "Be still," said a voice kindly. "Frank is safe in the next boat." Jack uttered an exclamation of relief and lay still, resting from his exertions. And so they came again to the _Queen Mary_ and were lifted aboard. Frank and Jack clasped hands when they stood on deck and Jack exclaimed: "By Jove! I thought it was all over when I couldn't find you down there." "I thought it was all over myself for a minute," said Frank. "That's one time when this old knife of mine helped out. I brought it back with me." He displayed the knife and patted it affectionately. "How do you feel?" asked Jack. "First rate. And you?" "Fine. Now we want to see Captain Raleigh." At this moment the third officer approached. "Captain Raleigh will receive you the moment you have put on some dry clothes," said the third officer. "But we must see him at once," exclaimed Frank. "Change your clothes first," said the third officer kindly. "But----" Frank began. "I have Captain Raleigh's orders for you to report to him the moment you have changed," said the third officer sharply. "You will hurry, if you please." Frank could see that there was no use protesting further. He shrugged his shoulders and the two boys made their way to their cabin. "The big chump," said Frank, as he slipped off his wet clothing. "The whole British navy might be sent to the bottom while we are doing this. What are a few wet clothes?" "I guess it was the way we went at it," said Jack. "If we had blurted out what we knew----" "To tell the truth, I've a good notion to say nothing about what I learned," said Frank. Jack looked at his companion in the greatest surprise. "Oh, no, you've not," he said at last, as he slipped on a dry shirt. "Don't you believe I haven't," declared Frank. "I'm mad. I don't like that way of doing things. Now if it had been Lord Hastings----" "Well, it wasn't," said Jack. "I'm afraid that's one trouble with us." "What do you mean by that?"
