Mr. Simms must have moved rapidly, for, two hours later that morning, after having seen many people, including the admiral, the Congressman sent a message upstairs urging Rhinds to come down at once.

As he stepped out from the elevator, a strange pallor on his face, John Rhinds beheld the Congressman standing with four men one of whom the old man knew for Ensign Pike, the naval officer who had been stationed aboard the 'Thor.' Another was Lieutenant Danvers.

Congressman Simms quickly presented Rhinds to the other two, one of whom was Rear Admiral Townsley, and the other Lieutenant Jasper, the Admiral's aide.

"Now, Mr. Rhinds," pursued the Congressman, "the admiral has decided that the first thing to do is to go aboard the 'Thor,' and see whether any hiding place exists in which you might have stored a fifth torpedo."

"But how could I get such a fifth torpedo?" faltered the old man.
"The Navy issues them."

"They may be bought in the market, too, by one who knows how," replied Rear Admiral Townsley, coolly. "You consent to our going aboard your boat, of course, Mr. Rhinds?"

Had there been any reasonable way of preventing it, Rhinds would not have agreed, but he saw that he must comply with the request.

Admiral Townsley raised a hand in signal. Out of the background came
Jacob Farnum and his three submarine boys.

"These people can't come aboard my boat!" protested Rhinds.

"They must, if we do," retorted the admiral, crisply. "These are the human beings who were placed in deadly peril by the torpedo that has yet to be accounted for."
