"I'm not sure," remarked Russ, as he put away the camera which he had had no chance to use after filming the start of the cowboys, "I'm not sure, but I think I recognized one of the fellows as the chap who was at Rocky Ranch when we arrived there."

"Then he has others with him," said Mr. Pertell.

"Evidently."

"And they will probably try to do us some more mischief," went on the manager. "We still have several important films to make, and if they try to steal our ideas and get the pictures we go to so much trouble to make we may as well give up."

"Don't you do it!" cried Baldy Johnson. "Don't you do it! We'll get after these fellows the first thing in the morning, and round 'em up good and proper."

"That's what we will!" cried his companion. "Whoop-ee for the round-up!"

"We'll pay 'em for startin' that fire," went on Baldy.

"Yes, and for stampedin' those cattle, too," added Buster Jones.

"Do you think they did that?" Mr. Pertell asked, quickly.

"I wouldn't be a bit surprised," declared Buster. "If they was mean enough to start a fire to spoil the picture they wouldn't stop at a little thing like stampedin' a bunch of cattle. I'm sure they done it."
