With the instinct that characterizes dogs, horses and other animals, Sunger knew that he must go on to the Post Office. Just what had happened to his master, of course Sunger did not know. But it was something wrong—the pony sensed that.

And so with the unconscious form strapped to the saddle, with Jack's head pillowed on Sunger's neck, the plucky animal started to foil the plans of the plotters. On and on he galloped over the mountain trail, Jack swaying from side to side, but remaining safe because of the holding ropes.

It was about this time that Ryan, who, by a roundabout road, had reached the trail leading from Tuckerton to Golden Crossing, looked at his watch in a secluded place where he was waiting, and remarked:

"Well, it ought to be working by this time. I guess I'll amble along and see what's doing. I ought to get the letters without any trouble. I certainly dosed his coffee good and strong," and he smiled in an evil fashion.

Springing into the saddle he urged his horse along the trail. He did not hurry, for he wanted to give the drug time to work its full and stupefying effect. Ryan was a different sort of worker from the other outlaws. He did not believe in their rough and ready methods, but, instead, used sneaking means, such as drugs, that were often no less successful.

"This hold-up work doesn't pay when you can get the same results without attracting so much attention," he murmured as he rode on. "Now I wonder if I had better take that last package they gave him. I don't believe the maps will be in that, though. They must be in the sacks. I hope I have a key that will fit the lock. I don't want to cut the bags if I can help it.

"If I can come up when he's lying unconscious, pick the locks, and get out what I want, I can lock the mail pouches again, and he won't know he's been robbed for some hours. That will give me that much more time to get away. Yes, that's my best plan," and as Ryan rode along he examined several keys which he took from a pocket. He had made his plans carefully.

It was not until the outlaw had reached a point near the spring that he began to be at all concerned. Up to then he had felt sure of the result of his desperate work.

"Why, I ought to have come upon him before this," he reasoned, wonderingly. "That stuff would knock out a strong man, let alone a lad like him. He ought to have fallen off, or have gotten off, and become unconscious before this. I wonder if I made any mistake."

He went over in his mind the different points of his plot. It seemed perfect. But where was his victim who should have been lying unconscious beside the road?
