"Let loose!" he shouted, trying to batter the boy in the face; but Frank ducked each time, and avoided punishment.

Several of the new arrivals, seeing that their services were not needed in the other case, rushed up to help Frank. Joey was soon as hotly beleaguered as his companion had been, and fighting still, went down under a half a dozen fellows.

"What does it all mean, Frank?" gasped Ben Cloud, as he sat upon the writhing figure of Martin, whom his comrades were holding down.

"Get them tied up first, and I'll tell you. Roll that fellow over on his face. If he objects make him eat dirt. Now, who's got some strong cord?" asked Frank.

"Here's a strap I had along with me," observed one boy.

"Fine! Couldn't be better. Cross his wrists, fellows. Hold still, now Martin, or you'll get something you won't like! Tit for tat, you know. You can examine the lay of the Columbia police headquarters for yourself, and not depend on me to tell you what things look like. There, that will do for you! Let him up, boys, but don't leave go of his arms."

"I've got the pistol George kicked out of his hand," said Sandy Griswold.

"Hand it here, then. Now, will you be good, you two? It's Columbia for yours, straight. Any more straps handy?" continued Frank briskly.

He had some specks of blood on his face, but did not seem to notice so small a thing as this in the general excitement of the hour. As luck would have it a second boy found that he had a strap around his waist he could spare; and accordingly Joey was accommodated in the same manner his larger companion had been.

A madder pair of rascals it would have been hard to find anywhere. To be captured at all was bad enough, but the idea of a parcel of boys accomplishing what all the police chiefs had been unable to do was humiliating.
