CHAPTER XX

Four Prisoners

When the Catwhisker arrived at Friday Island again, the place appeared to be deserted.

The camp was as they had left it, except that the breakfast dishes were washed and put away. "Friday" had performed his duty, but both boys had disappeared, and there seemed to be only one explanation of their disappearance, namely, the premonition of danger at the hands of the four strange men that the Rockport amateur, Max, had received from the boys on the island. No damage had been done to the tent or any of the camp paraphernalia, even the radio outfit being exactly as it had been when they left it in charge of Hal and Bud a few hours previously.

"This is getting pretty serious," Mr. Perry said, after they had made an unsatisfactory review of the situation. "I confess I don't know what to make of it."

Cub felt an impulse to brand this new affair as the most puzzling mystery that had yet confronted them, but he checked the utterance wisely enough as entirely too facetious for the occasion.

"We've got to get the authorities busy on this case," Mr. Perry added after a few moments' hesitation. "We may be sure now that it's more than a hazing affair. There must be a retreat of some bad men around here somewhere."

"What authorities shall we ask to help us?" Cub inquired.

His father seemed about to answer, but he hesitated a moment or two, with a puzzled look, first at his son, then at Mr. Baker.

"That's so," he said presently. "Where are we—in Canada or the
United States?"

"I think we ought to apply for help in both New York and Ontario," said Mr. Baker, who was ordinarily a man of quiet demeanor, but now was worked up to a state of nervous worry over the fate of his son.

"It's going to take some time to make trips to both sides of the river and get the authorities of New York and Ontario busy," said Mr. Perry; "but I suppose that's the only thing to do, and every minute wasted is an opportunity lost. So let's go right away."

"Hold on, father," Cub interrupted; "you forget that we have a means of calling help right here."

"It won't do to depend on your radio messages" his father replied. "You know the experience Mr. Baker's son had trying to get help that way."

"Yes, but there were conditions that queered his calls," Cub replied.
"Just remember the results we got by calling our new friend, Max, at
Rockport, and what he did for us. Unless I'm badly mistaken, we can look
for more help from him."

"Yes, you're right, Bob," Mr. Perry admitted. "But I don't like the idea of staying here and depending on a few boys to take care of so big a proposition. We need to arouse the whole country around here, including all people along the shores, on the islands and those boating up and down the river."

"In other words, there must be some real broadcasting," Cub interpreted.

"You bet you, and more than any amateur radio station in the country can do. Now, we've wasted too much time already. Come on; we've got to get started without any more delay."

"But let me stay and see what I can do while you're gone," Cub pleaded. "I bet I can have a police boat headed this way before you reach the mainland."

"No, nothing doing," his father ruled unwaveringly. "You'd disappear just the way the other boys did. We can't afford to run any more such risks."

"I'd be safe enough if you let me have that automatic o' yours, dad,"
Cub argued,

"No, sir-ree; I'm not going to leave you here alone to fight any gun battle with a band of bandits."

But the boy was still undismayed by his father's resoluteness. He had one more proposal to offer, and he presented it thus:

"You don't need to leave me here alone, dad. Mr. Baker may stay; you can run the Catwhisker alone."

Both men had started toward the landing place, expecting the boy to follow, but they stopped suddenly and faced about on hearing this new proposition. Mr. Baker looked almost eagerly at Mr. Perry, it seemed, and, observing that the latter's unyielding attitude had softened somewhat, he said:

"That's agreeable to me if it is to you."

"Well," returned Mr. Perry with slow deliberation, "that sounds pretty good. If it suits you both, it suits me. I don't think you'll have to use the guns, even if any bad actors do happen around. If you show them, that'll probably be enough. Do you know how to handle an automatic, Bob?"

"Sure I do," the latter replied. "All you have to do is keep the nose pointed away from you and toward the target you want to hit. To shoot, you just keep pulling the trigger, and when it's empty you're safe from accident until you fill the chamber again."

"That's a simple statement of facts," Mr. Perry smiled; "but you left out the most important of all, and until you tell me what that is, I'm not going to let you have it."

"Oh, I know what it is; you've told it to me lots of times," Cub replied with eager alertness. "You know, dad, I always remembered what you told me, and I didn't forget that advice of yours about fire-arms. It is, 'always handle an unloaded gun as if you know it's loaded.' I promise you, dad, I'll not forget it this time."

"I guess it's safe to let you have it," said Mr. Perry, handing over the weapon. "All right, now that everything's settled, I'll be gone and you two see what you can do through the air."

That ended the discussion, and a few minutes later the owner of the Catwhisker was putting all the speed he could put into the power boat toward the Canadian shore, while Cub devoted all his energy and skill to the task of summoning as much aid as possible by wireless, Mr. Baker standing by and waiting eagerly for results.

And results were not long coming. The yacht was scarcely out of sight beyond the outer rim of islands, when Cub recognized the call of Max Handy, the Canadian amateur at Rockport. He acknowledged the call, and then telegraphed the following:

"I am the boy whom you met at the depot a few hours ago. When we got back, we found the two boys we left here were gone."

"I knew something had happened," Max replied. "After I left you I got their S O S. Then one of them telegraphed that some men had seized his friend and were coming after him. His last message was broken off in the midst of a new S O S. I couldn't get him again, I called up the police and they said they would see it got to the proper authorities for investigation."

Cub translated this message for the benefit of Mr. Baker and was about to continue the telegraphic conversation when four men, armed with clubs, and with anything but friendly demeanor, appeared on the scene. Mr. Baker saw them first and sounded the alarm.

"Here they come," he said in low tone, the accents of which caused Cub to start to his feet and reach for his father's pistol which he had laid on the radio table. "Be careful," the man continued. "Don't shoot unless I do. Maybe we can get some information from those fellows. Put your gun in your pocket and don't draw it unless they attack us or you see me draw mine."

The movement of Cub, transferring the automatic from the table to the right pocket of his coat, did not escape the notice of the visitors, who appeared to have come from the wooded depths of the island. But evidently their uncertain vision left their minds in a condition of doubt as to the significance of the act, for they continued to advance, however, with some appearance of caution.

"I'll go forward a few steps to meet them," said Mr. Baker, in a low voice to Cub. "You stay back here and be careful with your gun. Don't use it unless you see me use mine; then keep your head. I think we'll be able to handle this situation without any violence."

He advanced half a dozen paces, then stopped and addressed the unwelcome visitors, who were now distant from him only about fifteen feet.

"Halt where you are, gentlemen," he said. "We are armed, and any further advance on your part will be met with the use of our weapons."

The "gentlemen" stopped with due consideration for the warning, but with scowls that indicated the poor grace of their obedience. A description of them would mark them as the ones who are heretofore recorded as having made an unfriendly call on Hal and Bud at the island camp earlier in the day. The tall, angular man again was spokesman for them.

"What're you fellers doin' on our island?" he demanded, with a deepening of his scowl.

"I didn't know the island belonged to you," Mr. Baker returned quietly.
"You don't happen to carry a deed to it in your pocket, do you?"

"No, but it's ours, or it belongs to one of us," the angry spokesman replied. "And we don't intend to allow any trespassing."

"We have no desire to do any trespassing," was the response to this veiled threat. "But I want to answer you with a clear statement of our position. We are here with a purpose and we don't intend to be turned aside from that purpose. To get down to brass tacks, three boys, one of them my son, have disappeared under remarkable circumstances from this island, and the indications point directly toward you men as responsible for their disappearance. What your motive is I have no idea, but you may be sure that it will be fathomed, and now that we have you in our power, we don't intend to let you get away from us. We are armed with automatic pistols that shoot like machine guns and one move either toward or from us, contrary to order, will start them barking. Now, my instruction to you is that you drop those clubs and come forward, one at a time, and allow my companion to search you for weapons."

As he spoke, Mr. Baker drew his pistol from one of his trouser pockets, and Cub did likewise. Instantly the scowls disappeared from the faces of the four men and were succeeded by looks suggestive of panic.

"There's no need of any such action by you," said the leader of the invaders with plaintive whine. "We ain't done nothin' out o' the way. We did drive those kids off o' the island, but we didn't hurt 'em. They're all right, and we c'n take you to 'em any time you want to go."

"How could you drive them off of here when they had no boat to go in?"
Mr. Baker demanded.

"Oh, we took 'em in our boat and put 'em on another island. If you'll agree to go away from here we'll produce those boys and land you anywhere you want to go."

"Why is it you're so anxious to have us go?" demanded Mr. Baker. "Is there something going on here that you don't want the authorities to know anything about?"

This shot seemed to throw confusion into the ranks of the visitors, judging from the expressions of their countenances. But their spokesman attempted to brush the inference aside as of no consequence to them by answering:

"That's foolish. If you think there's anything bad going on here, just bring on the police and investigate; but we don't intend to have anybody on these islands who hasn't any right here."

"Very well, we'll make a test of the question of rights so there won't be any dispute about it hereafter," said Mr. Baker. "Robert, will you call your friend at Rockport and tell him to send some officers here for four prisoners, but keep your weather eye on these fellows meanwhile and your pistol beside you ready for instant use."

Cub did as directed and soon was dot-and-dashing a thrilling message to Max Handy, who had been waiting apprehensively all this time for an explanation of the island operator's protracted silence.
