"Smoky Griffin."
"He went out through the window," groaned Batts.
"Ned, have you got Smoky?"
"You bet."
"That's all, then. No one else in there, is there, Batts?"
"Go find out if you want to know," growled the mountaineer.
"All right, I will." Tad swept the interior of the cabin with a flash light that he had brought along, and found that all of the men were out. "Gather them in, Mr. Rodman. All clear within."
With a yell the Pony Rider Boys and the prospectors sprang forward and a few moments later the prisoners, whose wounds Professor Zepplin had dressed, were securely bound. Smoky was attended to by Ned Rector.
An examination was then made of the cabin. In the cellar were found a gasoline engine with which the dynamo was operated, and a powerful wireless outfit. Papers which proved to be of great value to the government agent also were found in a secret compartment under the cellar floor. At the direction of the Secret Service man, for reasons known to himself, the plant was left as it was for the time being.
Early the following morning the prisoners were loaded on ponies, and the long journey to the railroad station was begun.
