“No,” the latter answered with a blank look, “but I think we could rig you up one.”

“Friends,” the aviator said with a look into their anxious faces, “I can see that you are in some kind of trouble, and from a hint that my friend Mason dropped, I think I can help you out. Just rig me up that dark room, Jack, and I will show you something that will surprise you.”

“There is a small closet in my room and you can use it,” Mason said quickly.

Taking the mysterious black tank with him the aviator left them and was in the room for a half hour. When he came out he held a number of films in his hands.

“Before I join these films together,” he said to his mystified audience, “I want to tell you of a little incident that happened to me this morning. Starting from a town about a hundred miles from here, and depending entirely on my compass, for I had no idea where the Bar X ranch lay, I crossed the railroad track at a point fifty miles below here.

“If you remember, there was a slight mist this morning, making it difficult to distinguish objects unless I flew quite low. Knowing I had a good supply of gasoline I opened the engine up wide and flew at a high altitude and drifted aimlessly in the hope that the mist would soon clear away.

“My wish was soon granted, but, to my surprise, I found myself flying over your wonderful mountains and hopelessly lost. Bringing the airplane around, I determined to cruise in the opposite direction.

“Flying at a lower altitude, I was surprised to see a group of men directly under me. The place was an ideal spot to land, and shutting off the engine I began to make spirals, at the same time taking this series of films you see in my hand.

“One of the men commenced to fire a revolver at me, and thinking it wouldn’t be healthy to land among them, I started my engine. After much difficulty, I succeeded in reaching this ranch. I didn’t know what ranch it was, but for once I was lucky.”

The aviator joined the films together and held them out to their startled eyes. It was a complete picture of the counterfeiter’s retreat in the mountains and showed the two girl prisoners!
