"I'll not complain to the doctor," returned Phil. "But I know what I will do," he added, quickly, as though struck by a sudden idea.

"What?" came from several.

"Never mind what. But I'll wager he'll give us more time."

"I guess I know what you think of doing," said Dave. "But take my advice and don't, Phil."

"Humph! I'll see about it, Dave. He isn't going to run such a thing as this up my back without a kick," grumbled the shipowner's son.

"Well, wait first and see if he doesn't change his mind, or if we can't get through in the week," cautioned Dave.

"What was Phil going to do?" questioned Luke, strumming lowly over the strings of his guitar.

"Oh, don't let's talk about it," cried Dave, before Roger could speak.

He did not wish the Mrs. Breen affair to become public property.

"Tell us about the wild man, and all the other things that have happened here since we went away."

"And you tell us all about Cave Island and those stolen jewels," said Buster.

Thereafter the conversation became general, Dave and his chums telling of their quest of the Carwith diamonds, and the other students relating the particulars of a feast they had had in one of the dormitories, and of various efforts made to catch the so-called wild man.

"I don't believe he is what one would call a wild man," said Ben Ba.s.swood, Dave's old chum from home, who had just come in from some experiments in the school laboratory. "He is simple-minded and very shy. He gets excited once in a while, like when he threw those mud-b.a.l.l.s."

"Well, you ought to know," remarked Buster. "Ben is the only fellow here who has talked to the man," he explained.

"When was that, Ben?" questioned Dave.

"That was when the man first appeared," answered the Crumville lad. "I didn't find out until yesterday that he was the wild man, and then it was because of that blue chalk he uses. I met him in the woods when I was out during that last snow, looking for rabbits with my shotgun. I came across him, sitting on a rock, looking at an old newspaper. He had some of the blue chalk in his hand and had marked a circle with a cross on the rock. He asked me where I was going, and told me to look out and not shoot a star, and then he asked me if I used chalk for powder, and said he could supply a superior brand of chalk cheap. I thought at first that he was merely joking, but I didn't like the look in his eyes, and then I made up my mind he was not right in his head, and I left him. When I came back that way, an hour later, he was gone, and I have never seen him since."

"Where was this, Ben?"

"Up in the woods, where the brook branches off by the two big rocks."

"I know the spot!" cried Roger. "Say, maybe he hangs out around there."

"No, we hunted around there yesterday, but he wasn't to be seen. I don't believe he has any settled place of abode, but just roams through the woods."

"Poor fellow! Somebody ought to catch him and place him in a sanitarium," was Dave's comment.

Various matters were talked over until the supper hour, and then the boys filed down to the dining-hall. Here our hero met more of his school chums, including Gus Plum, who had once been his enemy but who was now quite friendly, and little Chip Macklin, who in days gone by had been Plum's toady.

"Very glad to see you back, Dave!" cried Gus. "And, say, you've certainly made a hero of yourself," he added, warmly.

"It was great, what you and Roger and Phil did," added Chip, in deep admiration.

Everybody was glad to see Dave back, and after supper it was all he could do to get away from many of his friends. But he managed it at last, and he, Roger, and Phil went upstairs, to put away their things and get out their schoolbooks.

"We have got to study and that is all there is to it," said Dave, firmly. "Fun is one thing and getting ready to graduate is another. We have got to get down to the grind, boys."

"That's right," answered the senator's son.

"But don't forget what old Haskers said," grumbled Phil. "He'll make us sweat, just you wait and see!"

"'Sufficient for the day is the evil thereof,'" quoted Dave. "I think we can get through if we buckle down hard."

"Supposing Mr. Dale and the other teachers pin us down as old Haskers did?" demanded Phil.

"They won't do it," declared our hero. "Take my word for it, Mr. Dale will give us a month, if we want it. I know him. And the others will do the same."

"Well, maybe we can get through, if that's the case," said the shipowner's son, slowly. "Just the same, I think old Haskers the meanest man alive."

The following morning, after a good night's rest, the boys went to their various cla.s.ses. As Dave had predicted, Mr. Dale, the head teacher, treated them with all possible consideration, for he loved boys and understood them thoroughly. The other teachers were likewise very lenient.

"Old Haskers is the one stumbling-block," said Roger. "Dave, maybe we had better see Doctor Clay about him."

"Not much!" cried Phil. "We've got a club we can use on Haskers. Why not use it?"

"You mean, go to him and tell him we know about that Mrs. Breen affair, and that we will expose him if he doesn't let up on us, Phil?"

said Dave.

"Yes."

"Do you think that is a--well, a gentlemanly thing to do?"

"It's what old Haskers would do, if he was in our place."

"Perhaps. But I'd rather not do it. Let my uncle's lawyer try to collect that money without our appearing in the case. We have had trouble enough in the past with Haskers. Let us buckle in and study up. I am sure we can get through," added Dave, earnestly.

"All right," growled Phil; but his manner showed that he was not satisfied.

Two days went by, and the boys settled down to the regular routine of the school. The lessons to be made up were exceedingly hard, and Dave found he had to study almost constantly to do what was required of him.

"But I am going to make it!" he murmured, setting his teeth hard. "I am not going to disappoint the folks at home."

One afternoon the three chums had a very hard lesson in Latin to do.

It was a clear, sunshiny day and they had one of the windows wide open to let in the fresh air. Dave and Roger were bending over their books when they heard a sudden exclamation from Phil.

"I'll be hanged if I'm going to do it!"

And then of a sudden a Latin book was hurled across the room, to land on a bureau, just missing the gla.s.s.

"h.e.l.lo!" cried Dave, raising his head. "What's wrong now?"

"I'm not going to do it!" cried Phil, stretching himself. "It's an outrage and I won't submit to it."

"You mean this boning away for Haskers?" queried Roger.

"Just that," answered the shipowner's son. "Why can't he treat us as fairly as the other teachers did? It wouldn't hurt him a bit to give us more time."
