Professor Potts was in the grasp of a miserly money-lender of Crumville named Aaron Poole, who had a son Nat, who could not get along at all with Dave. Mr. Poole was about to foreclose a mortgage on the professor's place and sell him out when something occurred that was the means of changing the whole course of the professor's own life and that of the youth who lived with him.

On the outskirts of Crumville lived Mr. Oliver Wadsworth, a wealthy manufacturer, with his wife and daughter Jessie. One day the gasoline tank of an automobile took fire and little Jessie was in danger of being burned to death. Dave rushed to her a.s.sistance and beat out the flames, and thus saved her. For this Mr. Wadsworth was very grateful. He made some inquiries concerning Caspar Potts and Dave, and learning that Professor Potts had been one of his former college instructors, he made the old gentleman come and live with him.

"Dave shall go to boarding school and get a good education," said Mr.

Wadsworth. And how Dave went has been told in detail in the first volume of this series, ent.i.tled "Dave Porter at Oak Hall." With Dave went Ben Ba.s.swood, his one boy friend in Crumville.

At Oak Hall, a fine seat of learning, located on the Leming River, in one of our eastern states, Dave made a number of warm friends, including Phil Lawrence, the son of a rich shipowner; Roger Morr, whose father was a United States senator; Maurice Hamilton, usually called Shadow, who was noted for his sleep-walking and the stories he loved to tell; Sam Day, known throughout the school as Lazy, why n.o.body could tell, since Sam at times was unusually active, and a score of others, some of whom have already been introduced. He also made, in those days, one enemy, Gus Plum. But Gus had since reformed, and was now as good a friend as any of the rest.

What troubled Dave most of all in those days was the question of his ident.i.ty. How he started to find out who he was has been related in my second volume, called "Dave Porter in the South Seas." There he did not meet his father, as he had hoped, but he did meet his uncle, Dunston Porter, and learned much concerning his father, David Breslow Porter, and also his sister Laura, then traveling in Europe.

When Dave came back to Oak Hall, as related in "Dave Porter's Return to School," he met many of his friends and succeeded in making himself more popular than ever. But some lads were jealous of our hero's success, and two of them, Nick Jasniff and Link Merwell, did what they could to get Dave into trouble, being aided in part by Nat Poole, the son of the miserly money-lender, who had followed Dave to the school. The plots against Dave were exposed, and in sheer fright Nick Jasniff ran away and went to Europe.

Dave had been expecting right along to meet his father and his sister, and when they did not return to this country, and did not send word, he grew anxious, and started out to find them, as related in detail in "Dave Porter in the Far North." It was in Norway that Dave first saw his parent, a meeting as strange as it was affecting.

After his trip to the Land of the Midnight Sun, our hero returned once again to school, as related in "Dave Porter and His Cla.s.smates." Jasniff had not returned, but Link Merwell was still at hand, and likewise the lordly Nat Poole, and they did what they could to make our hero's life miserable. In the end Merwell did something that was particularly despicable and this caused Dave to take the law into his own hands and he gave the bully the thrashing that he well deserved. Merwell wanted to retaliate in some manner, but in the midst of his plotting, word of his wrongdoings reached the head of the school and he was ordered to pack up and leave, which he did in great rage.

While Dave was off hunting for his father and his sister, Laura Porter had been visiting her friend, Belle Endicott, at Mr. Endicott's ranch in the far west. Belle was anxious to meet her girl chum's newly-found brother, and this led to a visit to the ranch, as told of in "Dave Porter at Star Ranch." Here Dave again met Link Merwell, and proved that the latter had been aiding some horse-thieves in their wicked work. Mr.

Merwell had to settle a heavy bill because of his son's actions, and then, for a short s.p.a.ce of time, Link disappeared.

With the coming of fall, Dave and his chums returned to Oak Hall, as related in the volume preceding this, called "Dave Porter and His Rivals." As his chief enemies had left the school, he did not antic.i.p.ate much trouble, yet trouble came in a manner somewhat out of the ordinary.

Nat Poole joined a group of students who had come to Oak Hall from another school, and the crowd did what it could to get Dave and his friends off the football eleven. Then, when Dave had once more fought his way to the front, came word that Nick Jasniff and Link Merwell were again "after his scalp," as Roger expressed it. Jasniff and Merwell were then attending a rival inst.i.tution of learning known as Rockville Military Academy.

"Be careful, or they'll play you some dirty trick, Dave," said Phil, warningly.

"I've got my eyes open," replied Dave.

In a rather unusual manner Dave had become acquainted with a man named Hooker Montgomery, a fake doctor, who traveled around the country selling medicines that he made himself. This man asked Dave to call on him, and when the youth did so he was suddenly seized from behind, made a prisoner, and carried off in a sleigh and then in an automobile. At first he did not know what to make of it, but at last learned that he was being held, for some purpose, by Merwell, Jasniff, Montgomery, and the fourth man, a mere tool. He watched his chance, and, at length, escaped, much to his enemies' chagrin.

"Have them all arrested," was the advice of Dave's chums, but this was not easy, since all of the evil-doers had disappeared. Then, one day, while on a sleigh-ride to a distant town, the boys fell in with Hooker Montgomery. The fake doctor was practically "down and out," as he himself expressed it, and said he would do anything for Dave, provided he was not prosecuted.

"It was all a plot gotten up by those two, Jasniff and Merwell," said Hooker Montgomery. "They promised me some money if I would help them, but I never got a cent." Then he said that Jasniff and Merwell were in town.

"We'll locate them," said Dave, but this was not accomplished until later, when the pair of rascals were encountered at a railroad office.

Our hero and his chums tried to stop Jasniff and Merwell, but the rascals rushed through a crowd and got aboard a train; and that was the last seen of them for the time being. The boys might have gone after the pair, but they had an important hockey game to play, and when they administered a stinging defeat to Oak Hall's ancient rival, Rockville Academy, Dave, for the time being, forgot that he had an enemy in the world.

"Two weeks more of the grind, boys!" cried Dave, on the following Monday. "And then home for the holidays."

"Right you are," answered Phil. "But, oh, those two weeks!"

On Wednesday one of Dave's chums celebrated his birthday, and among the presents received was a very fine double-barreled shotgun. This lad immediately wanted to go hunting; and the result was that the boys applied to Doctor Clay for permission to go to Squirrel Island, up the river, on a hunting expedition, the following Sat.u.r.day. There was just sufficient snow on the ground to make rabbit and squirrel tracking good, and the boys were told that they might remain away all day. Six of them had guns and two had revolvers, and they carried in addition a good-sized hamper of provisions for lunch.

"Now, boys, be careful and don't shoot yourselves or anybody else," said Doctor Clay, with a smile, when Dave, Roger, and Phil left the school building. "Don't fire at anything until you are certain of what it is.

Every hunting season somebody is killed through the sheer carelessness of somebody else."

"We'll be careful," answered Dave.

"Do you think you'll get any game?" And the doctor continued to smile.

"I hope to bring you at least a brace of rabbits or squirrels, Doctor."

"Well, I wish you luck. And don't stay too late," returned the head of the school, and then with a pleasant nod he dismissed them.

Dave, Roger, and Phil were the first at the place of meeting, but they were quickly joined by all the others except Ben.

"I'll tell you what, Phil," said the senator's son, when he had a chance to talk to Phil alone. "Something is wrong with Dave. He isn't himself at all. Can't you see it?"

"Of course I can, Roger," was the reply of the shipowner's son. "If I get a chance to speak to him about it, I am going to do so. But I've got to be careful-I don't want to hurt his feelings."

"When you do speak, give me the sign, so I can hear what he has to say, too," went on Roger, and to this Phil agreed. Then came the start up the river, and a little later Phil broached the subject, and Dave made the dismaying announcement that Jasniff and Merwell were doing their best to bring disgrace to himself and his family and ruin them.

CHAPTER III-WHAT DAVE HAD TO TELL

"It's rather a long story, and I scarcely know how to begin," said Dave, after he, Phil, and Roger had skated ahead and to the right, where the others were not likely to overhear the conversation. "But, to begin with, Jasniff and Merwell have been to Crumville since they left here in such a hurry, and-I have some reason to believe-they have been here in town, too."

"Here!" cried the shipowner's son.

"Yes."

"Why didn't you tell us of this before?" asked Roger.

"I didn't know of it until lately, and I didn't want to worry you over my private affairs."

"But what have they done?" demanded Phil, impatiently.

"As I said before, Phil, I hardly know how to begin to tell you. But to plunge right in. In the first place, when they were in Crumville they followed my sister Laura and Jessie Wadsworth to a concert by a college glee club. They forced their attentions on the two girls, and gave outsiders an impression that they had come as escorts. The girls were so upset over it that Laura wrote me that Jessie was actually sick. Two days after that, when the girls were out walking one evening, Jasniff and Merwell followed them, and right on the main street, near the post-office, they came up and commenced to talk and Merwell said to Laura, loud enough for half a dozen folks to hear: 'You've got to keep your word-you can't go back on us like that.' And Jasniff added: 'Yes, you girls were glad enough to let us give you a good time before, down at the Rainbow.' The Rainbow is a ten-cent moving-picture place, and a low one at that. Of course there wasn't a word of truth in it, but Merwell and Jasniff gave folks the impression that Laura and Jessie had been going out with them, and you know how such reports spread in a small town like Crumville."

"The hounds!" exclaimed the senator's son, wrathfully. "They should have been run out of town!"

"Why didn't the girls tell your folks?" asked Phil.

"They did, as soon as they got home, and my father, Uncle Dunston, and Mr. Wadsworth went out to look for Merwell and Jasniff, but they were not to be found. But that was only the beginning. The next day an old lady came to the house with a letter she had picked up in the post-office. It was addressed to Link Merwell and had my sister's name signed to it, and stated that she was sorry they had quarreled and wouldn't he please forgive her and take her to the dance as promised? Of course the whole thing was a forgery, and it was dropped in the post-office just to make talk. I suppose Merwell thought some chatterbox would pick it up and spread the news."

"But what is his game?" queried the shipowner's son. "I don't see how he is going to gain anything by such actions."

"He wants to ruin our reputations, just as he and Jasniff have ruined their own. But I haven't told you all yet. A day later my father heard of another letter being found, in which Laura and Jessie promised to go off on a joy-ride in an auto with Merwell and Jasniff. Then Merwell and Jasniff appeared in Crumville with a stunning touring car, and they had two girls with them, loudly dressed and heavily veiled, and the whole four tooted horns, and sang, and behaved in anything but a becoming fashion. A good many folks thought the veiled girls must be Laura and Jessie, and you can imagine how my sister and her friend felt when they heard of it."

"Those chaps ought to be arrested," murmured Phil.

"And tarred and feathered," added the senator's son.

"After that, my father and Mr. Wadsworth got after them so sharply that they left Crumville. That was only a few days ago. The very next day came a lot of goods to the house, delivered by a large city department store. The folks hadn't ordered the goods and didn't know what to make of it. They investigated, and learned that a young woman calling herself Laura Porter had selected the things and had them sent out. Then came other goods for Mr. Wadsworth, said to have been bought by Jessie. It was an awful mix-up, and it hasn't been straightened out yet."

"It's the limit!" muttered the senator's son. "I'll wager your dad and Mr. Wadsworth would like to wring those chaps' necks!"

"Wait, you haven't heard it all yet," went on Dave, with a sickly smile.
