Unluckily one of them dropped an oar, which fell to the bottom of the boat with a loud clatter.
"What"s that?" demanded the officer of the deck sharply.
"It sounded like an oar in a small boat, sir," answered Dan, making for the topside, which, he reached in a few swift bounds.
"Something going on down there, sir."
"Where away?"
"Just aft of the port boom, sir."
"Can you see the dinghy?"
"Aye, aye, sir. Just make her out."
"Is she all right?"
"She looks to be, sir. I can"t quite tell from here. I"ll get over that way; I"ll go further forward, sir, and let you know. I see two dinghies now. The port and starboard dinghies are moored to the port boom, sir."
"Watch them while I turn out the guard."
"The dinghy is moving, sir. I think there is some one in her."
"Dinghy, there, ahoy!" bellowed the officer of the deck.
There was no reply from the men in the dinghy, who, by this time, were making more frantic efforts to free themselves.
"Dinghy, there!" shouted Dan. "What are you doing down there?"
Dan"s hail, like that of the midshipman, met with no response.
"Lay forward, anchor watch!" shouted the officer of the deck.
A quartermaster came running to the quarterdeck.
"Lower away the first whaleboat. Turn out your men in a hurry.
Boatswain"s mate!"
"Aye, aye, sir," bellowed a deep voice somewhere down one of the corridors leading off from the quarter-deck.
"Turn out the c.o.xswain of the second whaleboat. Look alive, everybody."
"Aye, aye, sir," chorused several voices.
"Anchor watch!"
"Aye, aye, sir."
"What are they doing?"
"Casting off, I think, sir."
"How many men?"
"Two, I think, sir."
The officer of the deck shouted a warning to the men and ordered them to return instantly to the ship; and then, addressing Dan, he shouted:
"Stop them, if you can!"
"Aye, aye, sir."
Dan"s raincoat and hat were off in a twinkling. These dropped one by one to the deck, as he sped along, bounding over obstructions that he did not even see, so familiar was he with the course he was following.
"They"re rowing away, sir. I"ll get them," shouted the Battleship Boy confidently.
He darted out on the lower boom, grasping the life line strung along its length for protection to the sailors pa.s.sing over the boom.
"Boat ahoy!" cried Dan.
The men bent to their oars; that is, one of them did, for there is but one pair of oars in a dinghy.
"It"ll be the worse for you men, down there, if you try to get away.
The whaleboats are being turned out to go for you, and I"m after you myself."
His warning had no effect, unless it were to hasten the work of the man at the oars. In his excitement the fellow let an oar slip from its fastening, keeling him over on his back in the boat. A muttered exclamation reached the boy on the boom.
Without an instant"s hesitation Dan crouched down on the boom, letting himself down until he hung suspended over the sea by his hands.
For a brief instant he peered down into the sea some thirty feet below him, taking mental measurement of the distance, figuring just how near he would come to hitting the dinghy were he to let himself go.
"I"ll chance it," he muttered. "It"s my duty to try. I am under orders to stop them, and stop them I will!"
The Battleship Boy let go.
His body shot downward, striking the water with a splash that was heard far back on the quarter-deck.
CHAPTER XIII
THE BATTLE OF THE DINGHIES
"Man overboard, off the port boom!"
"Stand by the falls. Whaleboat number one!" cried the officer of the deck.
