“Huh!” snorted Elfreda, at which Hippy grinned.

But it was serious business and Hippy soon sobered.

“Come, Tom, let’s look for traces of the robbers. The rest of you had better not come. It might confuse the trail.”

The two made a thorough search near the spot of the hold-up and came to the conclusion that only two men had been engaged in the work. Soon after this Hippy, peering behind some bushes, picked up something from the ground.

“Well, any results?” asked Colonel Scott when the searchers were back near the coach.

“Nothing positive,” answered Hippy. “By the way, Colonel, did you tell your driver to notify the park guards?”

“Yes.”

“Well, nothing more can be done to-night. Your driver had better start back at once to the hotel for another coach. Meanwhile, the rest of you come to our camp for the night.”

This was agreed upon and the large party lay down in some fashion in the camp of the Overland Riders to get what sleep they could. Only Hippy sat by the fire, eyes open. Badger tossed restlessly for a long while, then, glancing at the wakeful lieutenant, turned over and slept.

At dawn the coach came rumbling up and was soon followed by four park guards.
