"What'd you do that for?" demanded Cullen. "Because we want the cowboy officers to get hold of you fellows, and beat you up!" answered George. "They'll do it, too, if they lay hands on you! Those fellows are our friends!"

"Where's that boy who stole my property?" demanded Katz.

"He was down in the camp when I left," replied George.

"Do you think he's with that crowd on the other side of the gulch now? Or would he stay at the camp?"

"He probably would come out in answer to George's signal," Tommy cut in.

The detectives whispered together for some moments. Although the boys could not hear a word they were saying, they understood very well what all the whispering was about. They were discussing the possibility of capturing Chester and forcing him to lead them to his father's hiding place. They did not, of course, know that the father was wandering over the mountains in a demented condition.

After a time the party passed on down the valley much to the disgust of the two captive lads, and disappeared from sight. Then the detectives left the angle of the ledge which had concealed them and motioned the boys down the slope. The lads obeyed wonderingly.

Arrived at the bottom of the gulch once more, the detectives halted for another long consultation. Katz seemed to be in favor of following the party which had gone down the valley in the hope of getting hold of Chester, while Cullen was of the opinion that they might be able to capture the escaped convict himself by lingering around the cavern where the fire had been so mysteriously kindled.

While the two discussed, not without some show of anger, the situation, the two boys kept their eyes fixed on the opposite cavern. George knew positively that it was the one which had been occupied by the escaped convict and his son, and he believed that in time the father would return to it. It seemed to him that Cullen was clinging to an opinion which might cause himself and friends serious trouble.

"Gee!" he whispered to Tommy, "I wish we could get these flatties to follow the cowboys! I'm afraid they'll catch Wagner if they hang around that cave over there!"
