“Well, this is a surprise!” remarked Felix Wagner, as he continued to stare at the five Riverport fellows who had leaped out so suddenly from the brush alongside the road, and completely surrounded him.

Fred was keeping his eyes on the other’s face.  He had expected to see Felix appear confused; but, strange to say, he was nothing of the sort.

“You just believe me, it is a surprise, all right!” exclaimed Bristles, half elevating one of his clenched hands menacingly.

Wagner observed the threatening gesture.  He looked from Bristles to the rest of the group by which he was encircled.  Then a grim smile broke over his face.

“Hello!” he said, briskly; “seems to be catching don’t it?  Our new doctor over in Mechanicsburg says one disease can be cured by a dose of the same sort of trouble.  He’s different from the old fashioned kind of doctors.  I heard about what happened to your friend, Colon; a man in a car that I knew, stopped me about a mile up the road and asked me if I’d seen anything of him.  Then he told me about how he had disappeared in the queerest way ever.  And now it looks like you wanted to put me in the cooler, so there wouldn’t be any sprinting at all to-morrow.  Well, you’ve got me, boys.  Now, what do you want?”

“Sounds pretty nice, Felix, but it won’t wash,” grunted Corney, shaking his head as if to indicate that he did not believe one word of what he heard.

“Own up, Wagner, that it was all your doings!” said Sid, coaxingly.

“Yes, what have you done with my cousin?  It’ll go easier with you if you turn in and help us find him!” exclaimed little Semi-Colon.

Fred said nothing.  He was still watching the varied emotions that fairly flew across the expressive face of Felix Wagner.  Gradually he found himself believing more than ever that the Mechanicsburg fellow was innocent.  What he had seen of Felix in the various games played between the boys of the rival schools had inclined him to look on the other as a pretty decent sort of chap.

“Well, I declare, is that what ails you?” burst out Wagner, presently, as he looked around the circle of angry faces.

“Just what it is,” replied Sid.

“We’ve traced you all the way up here, and we’re bound to rescue our chum, or know the reason why,” Bristles declared.

“You thought that old covered wagon of Toby’s, and his limping white horse, would be a smart dodge; but we found you out,” Corney threw at the boy at bay.

Then the comical side of the affair seemed to strike Wagner.  He threw back his head and laughed heartily.

“Oh! yes, it looks funny to you, perhaps!” cried little Semi-Colon; “but just think of what his poor mother suffered when she went into his room this morning, and found that Colon hadn’t slept in his bed all night, and that he couldn’t be found anywhere.  Now, laugh again, hang you!”

Wagner instantly sobered up.

“I don’t blame you one little bit for feeling sore at me, if you think I had any hand in such a low-down business,” he said, earnestly.  “Why, I can prove it by Mr. Ketcham, the gentleman in the car I told you about, who gave me the news, that I was hot under the collar, and said, over and over again, that it was a mighty small way to win games.”

“Oh! you said that, did you, Felix?” mumbled Bristles, eyeing the other suspiciously; for he was slow to change his mind, once it was set on a thing.

“More than that,” continued Wagner, stoutly; “I told him plainly, and he’s on the committee of arrangements for your town too, that I’d never run in a race when my worst rival had been spirited away just to throw the game, either to us or Paulding.”

“Gee! that sounds straight!” muttered Sid.

“Stop and think a minute, Sid Wells,” the accused lad went on; “you’ve known me a long time, and we’ve been rivals from the days when we were knee high to grasshoppers; but did you ever know me to attempt a dirty trick?  Haven’t I always played the game for all it was worth, but square through and through?”

“That’s right, Felix, you have,” assented Sid, heartily.

Even Bristles found himself compelled to nod his head, as if ready to say the same thing if asked.

“All right then,” Wagner went on, “I give you fellows my sacred word of honor that I never dreamed such a thing had been thought of or attempted, until Mr. Ketcham told me, a little while ago.”

“But what are you doing away out here, Wagner?” asked Corney.

“Not taking a practice spin, because you haven’t got on your running clothes,” Semi-Colon declared, meaningly.

“Sure I haven’t, because I promised my mother I’d only run this afternoon.  She’s afraid I’m going it too strong, and that I’ll break down under the strain to-morrow.  And besides, I’m in apple-pie shape for the race right now.  As to my being here, why I went over early this morning to Tenafly with my father’s lawyer, Mr. Goodenough, to attend to some business for my dad.  Ask him if it isn’t so?”

“Oh! was that it?” remarked Bristles; “why, didn’t he go himself, Felix; tell us that?”

“We had to have the doctor over last night to see dad; he had another attack of lumbago, and can’t move this morning.  And, as this matter had to be looked into to-day, he asked me to go with his lawyer, and bring back the papers.  I’ve got ’em right here.”

Wagner flourished some legal-looking documents as he said this.  They settled the matter, so far as Fred was concerned.

“Wagner, you’ll have to excuse the way we jumped out on you,” he said, smilingly.  “You couldn’t blame us.  We’ve tracked that covered wagon right up here.  We happen to know that it belonged to Farmer Toby; and a woman heard the struggle on the road when Colon was captured.  And you see, some of the boys are dead sure our chum is being kept hidden in what they call the old haunted mill, right beyond us.”

“Whew!” ejaculated Felix, apparently now deeply interested.  “Where could a better hiding place be found for keeping a fellow, I’d like to know?  And boys, if you’re going to rescue Colon, count me in the game.  Now don’t say a word, because I won’t take no for an answer.”

“That’s mighty nice of you, Wagner,” said Sid, thrusting out his hand with his usual impulsiveness; “but perhaps you’d better think twice before you make up your mind to join in with us.”

“Say, why should I hold back?” demanded the other, aggressively; “I don’t think I’m any more of a coward than the rest of the bunch.  Here, let me get a club, like the one Bristles Carpenter has.”

“But hold on, Felix; perhaps you might not like to use it?” suggested Fred.

“Think so?” cried the other; “then you’ve got another guess coming, Fenton.  Just why mightn’t I want to get in a few whacks at the cowardly curs that kidnapped Chris Colon?”

“Well, they might turn out to be some of your best chums,” replied Fred.

“Wantin’ to do you what they thought a good turn,” added Corney.

“By cutting out the fellow you had to fear most of all, my cousin Chris,” Semi-Colon continued.

“Oh! that’s the way the land lies, does it!” observed Wagner, grimly.  “You believe this job was the work of Mechanicsburg boys; do you?  Well, I think differently, that’s all.  But if it turned out to be my best chum I’d just as lief thump him as not.  I’d be ashamed to own a chum who would be guilty of such a trick.  I’d never look at a prize won under such conditions, without turning red, and feeling foolish.”

“But see here, how’d you get over to Tenafly, Wagner; and why didn’t you go back the same way?” demanded Bristles.

“We went over on the seven-ten train this morning.  The agent will tell you so, for he sold us tickets, and was chatting with both of us.  Mr. Goodenough met a friend over there who invited him to stay to dinner.  So I said, rather than wait until noon, I’d just pump it on foot for home.  I thought it might be a good way to tune up for the afternoon whirl, without breaking my word to mother.  That’s all.”

“And it’s enough,” said Fred.  “Fall in, Wagner, and come along with us.  We might be glad to have another fellow along, if it happens that after all tramps carried Colon off, as some people say.”

“All right, fellows, I’m with you,” remarked Felix.  “And I declare, if here isn’t just the stick I’m looking for, sound enough to send in a home run with.  Must have been waiting for me.”

With these words Wagner joined the little group that hurried along the road.  As they reached a certain place Sid, who was in the lead, suddenly turned aside.  It was what had once been a serviceable lane, but which was now overgrown with weeds and underbrush.

“Wait a minute,” Fred remarked, in a low voice.

They saw him looking closely at the ground, and almost immediately he raised a smiling face toward the balance of the group.

“We made a center-shot when we guessed about this old mill, boys,” he observed, nodding; “because here are the plain tracks of a wagon; it came in lately too, and went out again.  The tracks show that it was here since that last little shower, which was two nights back.  Now for the mill, Sid.”

Gripping their cudgels tightly in their hands; and with compressed lips, as well as determined-looking faces, the little bunch of boys followed the sunken lane as it left the main road, and ran into a wilderness of woodland.

Then suddenly they realized that there was a musical sound of dripping water close by.  It seemed to thrill every nerve, and make six boyish hearts beat at a double pace.

Two minutes later, on emerging from the tangle, they saw the ruined old mill before them.  And it certainly did look just as “spooky” as Sid had declared, when he suggested that they might find their missing comrade hidden there.
