this hulk fer.”

“Hush! Not so loud, pop. Ther sound carries tur’rble fur over ther water.”

“As if I didn’t know thet, Zeb, but what do we care? Them kids is fast asleep, and anyhow, we cut the dinghy adrift so they couldn’t do us any harm ef they wanted to.”

“Thet’s right, too; but some of ’em might be prowling about. They’re up ter all sorts uv tricks. I ain’t forgot thet thar fence, I kin tell yer. My arm’s a-tingling yet whar thet electricity hit me.”

Soaked through as he was, and chilly into the bargain, Harry couldn’t help smiling as he heard this eloquent testimonial to the efficacy of the “charged” fence. He had caught the name of “Zeb,” too, which speedily removed all doubt from his mind as to the identity of the marauders.

“The precious rascals,” he thought, while his teeth chattered with cold, “I’m mighty glad I did swim out here, even if I am almost frozen to death. If they aren’t under arrest to-morrow it won’t be my fault.”

Little more was heard from the schooner, but from what he could catch he surmised that the two fishers were completely mystified by the craft. Presently he heard their footsteps descending the gangway and then came the splash of oars. They were dipped silently no longer, a pretty sure sign that the two rascals didn’t much care if they were heard or not. After a moment the splashing sound grew more remote, and Harry knew that the two prowlers had taken their departure.

There was a scull in the motor boat and as soon as he was sure that the Daniels were out of earshot, Harry up anchored and began sculling the motor boat toward the hulk. The distance was so short that he did not want to bother to start the engine, and in a few seconds he was alongside the dark hulk. He shoved along the side till the motor boat grated against the gangway, and then, not forgetting to make the motor craft fast, he leaped up the steps, with the purpose of discovering what harm, if any, had been wrought aboard the Betsy Jane.

Harry knew where a lantern was kept, and descending into what had once been the cabin he began rummaging about for it. In the pitchy blackness the task took him longer than he had anticipated, but at last he found the lantern and the matches which lay beside it. Hastily striking a light he soon had the bare cabin filled with the yellow rays of the lamp. As has been explained, the Betsy Jane had been purchased as a sort of “trying-out” appliance for the inventions of Dr. Perkins, and therefore the cabin contained nothing in the way of furniture. The lamp, in fact, had only been placed on board as a precaution in case a riding light was ever needed on the anchored hulk. But as she had remained at her moorings in the isolated cove this was not, of course, necessary.

A brief look about the cabin showed Harry that nothing had been molested there. In fact, as has been said, there was nothing to molest. A door in the forward bulkhead led into the empty hold, and the boy next made his way there, the lamp casting weird shadows on the timbers as he went. His steps rang hollowly through the deserted ship, and he could hardly repress a shudder as he threaded his way among the stanchions, which, like the pillars in a church, upheld the deck above his head.

Reaching what had been the forecastle of the Betsy Jane, Harry came to the conclusion that nothing had been damaged below. His next task was to go up on deck. His examination below decks had been painstaking, and had occupied him some time, but he was determined to make it a thorough one. The fact is that an ugly suspicion had crept into Harry’s mind as he lay in the bottom of the motor boat listening to the two Daniels on board the schooner. This was nothing more nor less than a dread that they might have “scuttled” the craft. From what he knew of them the two were capable of anything, and he thought that in their rage at finding nothing on board that they could damage they might have bored holes in the schooner in order to sink her. His investigation of the hold, however, had shown him—to his great relief—that nothing of the sort had occurred.

Coming on deck Harry made as careful a search for damage as he had done in the hold. But the inclined superstructure remained intact, and nothing indicated that the Daniels had done anything more than stroll about, trying to discover what the object of the schooner was.

So intent had Harry been on his task that he had, for the time being, completely forgotten that Pudge must be anxiously looking for him. Going into the eyes of the craft he sent a hearty hail ashore:

“Pudge ahoy! Oh-h-h-h, Pu-d-g-e!”

Then he stopped to listen intently. But no reply came to his hail. He tried it again and again, without success. Then he determined as a last resort to fire the agreed-upon three shots. He did not want to alarm his companions unnecessarily, but surely, he thought, it would be a good idea to arouse them and communicate what had occurred since he left the hut.

Up to that moment the boy had completely forgotten that he had left the pistol on the beach. He felt compelled to laugh at himself for his absentmindedness, but while the laugh was still on his lips something happened that caused it to freeze there.

A mass of cold spray was suddenly projected over the bow. At the same instant the old hulk quivered at the smart “slap” of a wave.

“Gracious!” thought Harry to himself, “the sea must be getting up. I reckon I’d best be going back ashore.”

As he made his way aft toward the gangway he found that the sea must indeed have risen since he came on board. The old hulk was rolling about like a bottle, and he had to hold on to the rail as he made his way along the decks. Getting into the motor boat under these conditions was no easy task. But it was accomplished at last.

“I guess I’ll start the engine before I cut adrift,” said Harry to himself.

Later on he was to be very thankful he did. Turning on the switch and gasolene he began to “spin” the fly wheel; but beyond a wheezy cough the motor gave no sign of responding. For more than half an hour the boy worked with might and main over the refractory bit of machinery, but to no effect. The engine was absolutely “dead.”

“What can be the matter with it?” thought Harry to himself. “It’s never acted this way before.”

He stood up, too engrossed in his problem to realize what a sea was running. Before he could recover his balance the pitching craft almost bucked him overboard.

“Gracious! the waves are getting up with a vengeance,” exclaimed the boy to himself; “I can never scull ashore in this sea. Queer, too, there, doesn’t seem to be any more wind than when I left shore. Certainly I’ve never seen the sea as rough as this in the inlet before.”

With the object of finding out what ailed the obstinate motor, he returned to the deck of the schooner where he had left the lamp. Getting into the motor boat with it once more, by dint of much balancing and holding on he cast its rays on the single cylinder. Almost simultaneously he saw what had happened. Somebody, he had no difficulty in guessing who, had removed the sparking points. No wonder that no explosion had followed his efforts to get the craft under way.

“Well, here’s a fine fix,” thought Harry; “even if I could attract their attention ashore I’ve got no means of getting there. Oh, if I won’t get even with those Daniels as soon as I get a chance! Wonder what I’d
