"There is some mistake," he said coldly. "I am well acquainted with Lieutenant Breen, and you are certainly not he."

Breen's face flushed hotly, but before he could reply, the captain broke in.

"Some mistake, hey?" said he, derisively. "I guess there is—another mistake—another bluff that don't go. Get out o' here; and I tell you now, blast yer hide, that if you make me any more trouble 'board my ship yer liable to go over the side feet first, with a shackle to yer heels. And you, young man," he stormed, turning to the ensign, "you look round, if you like. There's my crew. All the navy officers you find you can have, and welcome to 'em." He turned his back, stamped a few paces along the deck, and returned, working himself into a fury.

Breen had not moved, but, with a slight sparkle to his eyes, said to the young officer:

"I think, sir, that if you take the trouble to investigate, you will be satisfied. There are two Breens in the navy. You know one, evidently; I am the other. Lieutenant William Breen is on shore duty at Washington, I think. Lieutenant John Breen, lately in command of the torpedo-boat Wainwright, with his signalman Thomas Johnson, are shanghaied on board this ship. There is Johnson talking to your men."

The young man's face changed, and his hand went to his cap in salute; but the mischief was done. Captain Bacon's indignation was at bursting-pressure, and his mind in no condition to respond readily to new impressions. He was captain of the ship, and grossly affronted. Johnson, noting his purple face, wisely reached for a topsail-brace belaying-pin, and stepped toward him; for he now towered over Breen, cursing with volcanic energy.

"Didn't I tell you to go forrard?" he roared, drawing back his powerful fist.

Breen stood his ground; the officer raised his hand and half drew his sword, while the blue-jackets sprang forward; but it was Johnson's belaying-pin which stopped that mighty fist in mid-passage. It was an iron club, eighteen inches long by an inch and a half diameter; and Johnson, strong man though he was, used it two-handed. It struck the brawny forearm just above the wrist with a crashing sound, and seemed to sink in. Captain Bacon almost fell, but recovered his balance, and, holding the broken bones together, staggered toward the booby-hatch for support. He groaned in pain, but did not curse; for it requires a modicum of self-respect for this, and Captain Bacon's self-respect was completely shocked out of him.

But Mr. Knapp and Mr. Hansen still respected themselves, and were coming.

"You keep back, there—you two," yelled Johnson, excitedly. "Stand by here, mates. These buckoes 'll kill someone yet. Look out for their brass knuckles and guns."
