The new-comer had no thought of prudence; but was evidently bent on landing in front of the camp on the outside of the island.

Jet shook Jim, at the same time placing his hand over the boy's mouth to prevent a possible outcry, and whispered:

"There's no time to lose. We must get there ahead of him, or the jig is up, and, according to the noise, he's rowing mighty fast."

Jim was on his feet in an instant, and the two started at full speed through the underbrush, paying little attention to the disturbance of the foliage, because Sam was so nearly intoxicated that he would not heed slight sounds.

"He'll land somewhere here," Jet said, breathlessly, as he halted where the glimmer of the camp-fire could be seen. "If he don't we must creep up while he's fastening the boat."

Sam was evidently amusing himself by making the light craft spin through the water, and when he turned for the sh.o.r.e the boys saw that they had stationed themselves in the most advantageous position.

It was not necessary to move out of their tracks, for after landing the man came directly toward where they were standing.

Jet raised his revolver by the muzzle, and Jim stood ready to make a spring.

Sam reeled along shouting for Bob and lurching from side to side.

The time had not come to strike the blow; but the boy, believing he was about to be discovered, struck at the fellow's head.

The blow was not delivered fairly, but glanced off, and instead of being stunned Sam was only alarmed.

Leaping back quickly, before Jet could strike again, he fired into the bushes from whence he believed the attack had come.

The bullet whistled so near Jim's nose that the young gentleman leaped back with a howl, and this outcry was sufficient to show Sam where to send another. Before the echoes had fairly died away the sound of hurried footsteps through the bushes told that the small guide had taken refuge in flight.

Jet was alone, amid darkness so intense that he had no means of judging the whereabouts of his enemy save by the flash when the revolver was discharged.

The knowledge of danger had sobered Sam, and he understood he must make a desperate fight or be arrested, for, quite naturally, the first thought was that the officers of the law were on his track.

Jet was wholly at a loss to know what course should be pursued.

Sam was not charged with a capital crime, and Harvey never intimated that he cared to take him prisoner, therefore to shoot now, save actually in self-defense, would be little less than murder.

Sam emptied the chambers of his weapon while retreating toward the boat, and that he had reloaded before reaching her was told by the second volley which he sent in the direction of Jet.

By the grating of wood and sand the amateur detective knew the boat was being pushed off from the sh.o.r.e, and at that moment he could have fired with a very good chance of hitting the mark; but he refrained from doing so.

The most important thing just now was to a.s.sure the safety of the prisoners in the other camp, and he made his way across the island hurriedly, lest by accident Sam should happen to stumble across his comrades.

Neither Jim nor the boat were to be seen when he arrived at the clump of trees where the craft had been moored.

The small guide had thought only of his own safety, and paid no attention to what might happen to his friend.

Jet would have tried to summon him by whistling, but for the fear Sam might hear the signal and come that way.

It was possible to swim across the intervening s.p.a.ce; but it would be at the cost of wetting both weapons, and he decided against the idea almost before it took form in his mind.

He splashed the water gently, hoping Jim would believe it a signal to come back.

Then he waited in silence nearly an hour, fancying all the previous work would speedily be undone, and when it seemed certain the small guide had deserted him entirely, he heard his name whispered.

"Is that you, Jim?" he asked in a low tone.

"Yes. Where's that feller?"

"Left the island, I think. Why don't you row in here?"

"Is it safe?"

"It won't be if you don't take me off precious quick."

This threat had the effect of deciding the timid guide, and in a few moments the boat was paddled alongside the bank.

"What did you run away for?" Jet asked, angrily, when they were a short distance from the sh.o.r.e.

"What for? Didn't you hear that bullet come across my nose?"

"Of course he fired; but there wasn't much chance of being hit in the darkness."

"There was too good a chance to suit me. If that bullet had come an inch nearer I'd be dead by this time."

"But it didn't, and when you found he hadn't hit the mark, you told him where you was by runnin' away."

"I couldn't help it," Jim replied apologetically. "I don't reckon I was cut out for a detective, an' when folks begin shootin' right at me I'm bound to run."

"Have you been up to the camp?"

"Not much. I stayed right here in the boat to find out what was goin'

on."

"Then there's no knowing but he has been ash.o.r.e and set the men free."

"If that's so the sooner we get out of this place the better," and Jim would have headed the boat toward the outlet, but that Jet prevented him by pulling l.u.s.tily on the other oar.

"Look here," the latter said, angrily, "if you act like this I'll dump you overboard, or shoot, whichever comes handiest. Now row for our camp, and do the best you know how, if you don't want to get into a pile of trouble with me."

Jim obeyed meekly, and a few moments later Jet was running at full speed toward the clump of cedars.

The encampment was, apparently, just as they had left it, and Jet gave vent to a sigh of relief as he ascertained that the prisoners were still bound securely.

Then he ran back to help Jim bring the boat ash.o.r.e, and the guide asked in a trembling voice:

"Are you goin' to try to stay here now?"

"What else can we do? It would be running a big risk to start in the boat with both men, for Sam is rowing around somewhere, and he's certain to help his friends if he sees them in trouble."

"Suppose he should find out we were here?"

"That's exactly what I'm afraid of. We must keep mighty close for a day or two, and then I'll try to send another message."
