"Your people know that we are here, of course?"
"Oh, yes, we"re not fools. We saw you from the first."
"And they know where you started for?"
"Sure."
"Is your father in the Diver?"
"I refuse to answer any more questions," Moore stormed. "You"ve got the upper hand now, but the time will come when things will be reversed. Release me!"
"Of course," replied Ned, "we"ll release you and give you the run of the boat! You came here to murder us, and so are ent.i.tled to the most courteous treatment!"
"Well, quit asking impertinent questions, then," snarled the other.
"You can at least do that."
Ned hunted up two pairs of handcuffs, ironed the prisoner, and then conveyed him to a little room used for storage purposes. Moore did not appear to like this program.
"If anything should happen," he declared, "I"d be left here to die like a dog."
"And serve you good an" right!" Jimmie consoled.
"What do you expect is going to happen?" asked Jack.
"Oh, I don"t know," was the hesitating reply. "Something might, you know."
The boys went out and shut the door, leaving young Moore protesting against the treatment he was receiving.
"Now," Ned said, when the boys were a.s.sembled in the large room, "it is plain that the rascals on board the Diver are preparing to attack us, or do something to imperil our lives. You saw how frightened Moore was when he was locked in that room."
"Yes, he seems to fear that he will be brought to death by his own friends," Frank said.
"What do you suggest?" asked Ned.
"Stay an" fight!" urged Jimmie.
"Hide away from them!" Frank proposed.
"Wait here until we see what they propose doing," Jack ventured.
"I think," laughed Ned, "that we"ll bunch your advice and utilize it all. We"ll hide in some deep spot until we see what they"re up to, and then we"ll fight."
"I reckon they are about five to one."
This from Frank, who preferred meeting the enemy on dry land.
"Oh, we can"t come to a hand-to-hand battle," Ned replied. "We"ve got to fight submarine fashion."
Without attempting any explanation of this observation Ned proceeded to make a careful inspection of the boat. There was a torpedo tube at the prow, and this he studied over for a long time.
"Goin" to blow "em up?" asked Jimmie.
"I was thinking," was the reply, "that we might use this as a bluff if we come to a tight place."
"Aw, what"s the use?" demanded Jimmie. "You don"t make bluffs! You get the winning hand before you call! If I had my way, I"d blow "em out of the water!"
"Yes, you would!" Frank said. "You"d be the first one to kick if we should attempt to put that thief in there out of the boat. You"re the tender-hearted little child of the bunch!"
All the boys laughed, including Jimmie, for they knew that what Frank said was the truth. Jimmie liked to talk of merciless measures, but he was not inclined to put them into practice.
"Well," Ned said, presently, "the Diver people will soon understand that something has happened to Moore, and will be after us. We may as well take a moonlight stroll."
The water tanks were filled, the power turned on, and the Sea Lion, with no lights in sight, save the one at the prow from which Frank watched the level ahead, began feeling her way to the south.
"The charts show a deep pit not far off," Ned said, "and we"ll hide there for a time and see if they give up the job of looting the wreck.
The loss of young Moore may scare them out."
"Why not go to the surface and air out the boat?" asked Jack. "Our air apparatus is all right, of course, but I like the real thing better.
We can drop down again in a few minutes."
"That"s a good idea," Ned replied, and in a moment the Sea Lion was lifting to the surface.
In half an hour she was down again, dark and silent, in the pit of which Ned had spoken. Occasionally the submarine was lifted a few fathoms in order that anything unusual in the vicinity of the wreck might be observed.
Sometime near morning the Diver was seen making her way to the north as if setting out for a long voyage. The lights of the craft showed plainly--that is, as plainly as lights ever show at that depth--and the Sea Lion had no difficulty in following her.
"She"s steamin" up!" Jimmie cried, presently. "I believe she knows we"re after her."
But the Sea Lion was equal to the task set for her, and all the remainder of the night the chase went on.
CHAPTER XI
JIMMIE GOES OUT HUNTING
"I hope she"ll make for some port where there is an American man-of-war,"
Ned said, as the sea grew shallower.
"You bet she won"t," Jack replied. "She"ll make for some out-of-the-way place where she can get rid of her plunder."
"Why don"t we go back an" see if she took all the plunder out of the wreck?" asked Jimmie.
"If we lose sight of her now," Ned answered, "we may have hard work picking her up again. If there is anything left in the wreck it will keep. The thing to do now is to catch her and recover what she took away, then have her held to await the action of the Washington authorities."
