"By your face."

"Have you ever seen Black Harry?"

"Yes."

"When?"

"Last night."

"Where?"

"On the northbound Chicago, Rock Island and Pacific express."

"You were on that train?"

"I was, and I saw Black Harry's face when he was unmasked by Robert Dawson--saw it distinctly. You are Black Harry!"

"You were never more deceived in all your life. My name is Frank Merriwell, as I can easily prove."

"Your real name may be Frank Merriwell, but you are the boy desperado who is known as Black Harry, and you are the chap who shot Mr. Robert Dawson."

The detective spoke with conviction, and it was plain that he really believed what he said. The boy began to look grave, as the situation was not exactly pleasant.

"You came from Elreno to Oklahoma City on the first train this morning, did you?" asked the youth.

"I did."

"How did it happen that you took this train back?"

"I spotted you. The moment I saw your face I knew you, and I shadowed you till the train started. I boarded the train with the determination to capture you. I seldom fail when I have resolved on a thing, and I did not fail this time."

"Then this is no joke?"

"You will find it is no joke."

"Well, I can't ride from this place to Elreno with my hands held above my head, as you must very well know."

"Of course you can't. I'll have to put the irons on you. Here, young man, hold this revolver to his head while I handcuff and search him."

He spoke to Cholly De Smythe, who had been watching, with staring eyes, his jaw dropped, and a look of amazement on his face.

"Haw?" squawked the dude, aghast. "What ith that you want, thir?"

"Take this revolver, and hold it to this boy's head. If he moves, shoot him as if he were a dangerous dog."

"Good gwacious!" gurgled Cholly. "I nevah touched a wevolver in awl my life! You will hawve to excuse me, thir."

"If you are determined to treat me as if I were a mad beast, I beg you to let some one who knows something about firearms handle that revolver," said the captive. "I will give you my word not to make any trouble if you lower the weapon."

"Your word does not count with me," declared the crafty detective. "I wouldn't trust you a second--not a second."

"I can show you my card, letters, and other papers to prove my claim that I am Frank Merriwell, a traveler."

"Black Harry would be likely to have such letters and papers ready for just such an emergency. That trick will not count."

"Oh, well, don't fool around with that loaded gun held up against my head! Put on the irons, and give me a chance to rest my arms. Hurry up!"

"Shust led me dake dat revolfer, mine friendt," said the voice of the Jew. "Uf dot poy tries any funny pusiness, he vill be deat, vid der accent on der deat."

"Can I trust you?" cautiously asked Burchel Jones.

"Vell, I dunno. You can uf you vant to. I alvays make a bracdice uf doin' a cash pusiness."

After some hesitation, the tenderfoot detective decided that he could not do better than trust Solomon, and the revolver was surrendered to the Jew.

"Don'd you vink!" commanded Solomon, as he screwed the muzzle of the weapon up against the lad's head. "Uf you do, you vas a deat poy!"

The detective searched the youth, removing a handsome revolver from one of his pockets. That was the only weapon found anywhere on his person.

Burchel Jones was disappointed, for he had expected to find "guns" and knives concealed all over the lad.

"Oh, you're slick--you're slick!" he said. "But you can't fool me. I know how to deal with rascals like you. I have handled hundreds of 'em--hundreds upon hundreds."

"You must be a very old hand in the business," said the captive, with a laugh. "Still, you seem to need a.s.sistance to capture a boy, who has made no offer to resist you, although he knows very well that you have no legal right to arrest him."

"Oh, you are ready with your tongue--altogether too ready."

Having searched the lad, Jones produced some manacles, and snapped them on the wrists of his prisoner.

"There," he said to Solomon, "you needn't hold the revolver to his head any longer. I have him foul now."

"Dank you," nodded the Jew. "You vas much opliged vor der use of my revolfer."

"Of course, of course."

"V'y you don'd puy dot revolfer, den, und gif a poor man a drade?"

"Oh, get out. I don't want it any longer."

"Vell, I am glad uf dat, vor it vas long enough alretty. Uf you like id so vel, v'y you don'd bought id?"

"I have one of my own."

"Vell, haf dwo. I gif you a drade on dat revolfer. I sell you dat revolfer vor elefen tollar."

"Don't want it."

"Ten tollar."
