"Well, we're out of the harbour safely, Captain," said Executive Officer Staples with a sigh of relief, as he spread out the chart of the Massachusetts coast and glanced at the "tell-tale" compass. "No more trouble till we get down by the Pollock Rip Shoals."

"Anybody would think you had been taking a battleship out from under the enemy's guns," laughed Lieutenant-Commander David Rexdale. "Don't talk about 'trouble,' Tel., while it's daylight, off a home port, in good weather!"

The two were standing in the chart-room, just behind the bridge of the U. S. gunboat Osprey, as the vessel, leaving Boston Outer Light behind, headed slightly to the south of east. Rexdale, as his old chum Holmes had predicted, was now in command of the Osprey, and was taking her to Washington for a practice trip, on which the crew would be drilled in various manœuvres, including target-practice. Lieutenant Richard Staples, his executive, had been the captain's classmate at Annapolis. He was lanky and tall, and at the Academy had soon gained the sobriquet of "Telegraph Pole," or "Tel.," for short; a name that had stuck to him thus far in his naval career. He was a Californian, and, while very quiet in his manner, was a dangerous man when aroused—as the upper-class cadets had discovered when they undertook to "run" him. Rexdale was from the rural districts of New Hampshire, and was known to his classmates as "Farmer," a term which was now seldom applied to the dignified lieutenant-commander.

The Osprey—to complete our introductions—was a lively little member of Uncle Sam's navy, mounting several six-pounders and a four-inch rifled gun, besides smaller pieces for close quarters. She had taken part in the blockade of Santiago, and while not as modern in her appointments as some of her bigger and younger sister-ships, had given a good account of herself in the stirring days when Cervera's fleet was cooped up behind the Cuban hills, and made their final hopeless dash for freedom. Rexdale was in love with his little vessel, and knew every spar, gun, plate, and bolt as if he had assisted in her building.

On the way down the harbour, they had passed the Essex and Lancaster, saluting each with a bugle-call. Besides the two officers mentioned, it should be added that there were on board Ensigns Dobson and Liddon, the former a good-natured little fellow, barely tall enough to meet naval requirement as to height; the other a finely educated and elegant young gentleman who had attended a medical college before enlisting, and whose fund of scientific and historical knowledge was supposed to be inexhaustible. He wore glasses, and had at once been dubbed "Doctor," on entering the Naval Academy. These, with Paymaster Ross, Assistant Surgeon Cutler, and Engineer Claflin, made up the officers' mess of the Osprey.

It was a fair day in June, 1903. The sunlight sparkled on the summer sea. Officers and men were in the best of spirits as the gunboat, her red, white, and blue "commission pennant" streaming from her masthead, sped southward past the long, ragged "toe" of the Massachusetts boot.

At noon Rexdale dined in solemn and solitary state in his after cabin. The rest of the officers messed together in the ward-room, below decks, and doubtless Dave would have been glad to join them; but discipline required that the commanding officer, however familiarly he might address an old acquaintance in private, should hold aloof at mealtimes. He was waited upon by two small Japanese men, or boys, who had easily obtained the situation when the vessel went into commission at the Charlestown Navy Yard, where she had remained for some months, docked for overhauling and thorough repairs. The two cabin stewards were gentle and pleasant in their manners, conversant with all their duties, and spoke English fluently. Their names were on the ship's papers as Oto and Oshima.

"Oto," said Rexdale, when the dinner was finished, "call the orderly."

"Yes, sir."

The marine was pacing the deck outside the cabin-door. On receiving the summons he entered and saluted stiffly.
