“Indeed we shall. I received orders just a little while ago to destroy a derelict that has been sighted off Nantucket Shoals. That’s what brought me aboard. You see I live in Staten Island—when I’m home. I’m waiting for my executive officer. The minute he comes aboard, we’ll hoist anchor.”

“Thank you, Captain,” cried Henry. “Won’t that be bully! I’ll be more than glad to go. But I ought to let my mother know what has happened to me. She’ll be worried when no letters come.”

“Entirely right,” said the captain. “Here’s my desk. You can write her a letter whenever you wish. If there was any way to reach her by wireless, we could send word to her at once from the ship.”

“Bully!” cried Henry. “Of course I can. The fellows at home will be listening in for me right after supper. We made that arrangement before I left home. I expected to call them up on the outfit Willie uses at the Secret Service headquarters.”

“Very good,” said the captain. “Then we’ll call it settled. And I hope you’ll enjoy every minute of our trip.”

CHAPTER III
THE SEARCH FOR THE DERELICT

So overjoyed was Henry at his sudden good fortune that he wanted to throw up his hat and cheer. But he knew that would never do. To hide the emotion that was struggling for expression, he stepped into the little stateroom that the commander now indicated was to be his, and so keen was his interest in this that he promptly forgot his desire to make a noise.

The captain’s cabin was in the after part of the ship, and the little staterooms, for there were two of them, occupied the very stern. These staterooms were twin compartments, one for the captain and one for his guests. A narrow passageway divided them. Each stateroom contained a snug-looking bunk, with a round air-port, or window, just above it, like a huge eye; and there was also a wardrobe, and a dresser with a mirror above it. Each stateroom, likewise, led into a private bathroom, as comfortably equipped as any similar room on land. The enormously high sides of the bathtub at once caught Henry’s attention, and he rightly guessed that these were to prevent water from slopping out of the tub when the ship was plunging in the waves. As soon as he had examined his quarters, he unpacked his little case, stowing his few articles of clothing in the dresser. Then he stepped back into the cabin to have a look at that.

Fortunately, the captain had gone on deck, and Henry was free to examine things to his heart’s content. The cabin would have filled the heart of any boy with delight. Occupying a cross section of the after part of the ship, it reached from side to side of the vessel, with rows of round air-ports on either side letting in air and light, and giving a view out over the water. Along either wall, directly under these air-ports, were leather-cushioned seats, where one could sit or lie at ease. In the centre of the room was a square oak table, now covered with a soft green felt cover. A sideboard was built into one side of the cabin, and Henry was interested to note how all the goblets and dishes were secured so that they could not fall from their places. Closets were also built into the sides of the room, and one corner was occupied by the captain’s desk, with his typewriter fixed on a movable shelf attached thereto. Doors led mysteriously into other parts of the ship, one of which, Henry later found, opened into the cabin of the captain’s steward or mess attendant. And of course there were comfortable chairs and electric lights everywhere, and books in a case, and some silver cups that Henry found had been won by the crew of the Iroquois at the annual manœuvres of the Coast Guard fleet at Cape May, and so many other snug and interesting things that he thought this was indeed the most delightful place he had ever been in. And now that the captain was not present, he wanted more than ever to give a loud whoop or two.

It is altogether likely that he would have done so, too, had he not just then heard the clang of the motor-boat’s bell alongside, and in another moment footsteps sounded in the companionway. Then the captain entered the cabin, followed by a tall, muscular-looking officer in full uniform.
