The self-styled policeman reached out with the flat of his hand, knocking Greg Holmes off his feet. But, as he did so, Dick dropped down in front of the man, wrapping both arms around the fellow's knees. Then Dick rose. It required the exertion of all his strength, but he succeeded in toppling Gus over onto his back.

At the same time Abner Dexter was having all he could do, for three very determined schoolboys were assailing him. At last Dexter turned to retreat, but Dan Dalzell thrust a foot before him and tripped him.

"All down!" yelled Dan. "Set 'em up in the other alley!"

Though downed for the moment, the two men were disposed to make a livelier fight of it than ever. It was a brisk, picturesque, rough-and-tumble fight that followed, in which the young boys got a deal of rough handling.

Frightened, yet fascinated, Mrs. Dexter tottered against the fence and stood looking on.

Things might yet have fared badly with Dick and his friends had not a newcomer arrived on the scene. He came running, and proved to be Policeman Whalen in uniform.

"Here! What's on?" demanded the Gridley officer. "Let up on kicking them boys! I want you!"

With that Whalen, who was a big and powerful man, grabbed Abner Dexter by the coat collar and pulled him to his feet. With this prisoner in tow, he moved up and seized Gus in similar fashion.

"Now, what's the row?" demanded Officer Whalen.

"Arrest these boys for assault!" quivered Dexter in a passion.
