Suddenly one of their number dashed off with his horse on a dead run to the east. He did not take a course toward the whites, but aimed for the elevation which extended in a southerly direction. It looked as if he meant to learn whether any friends of the little garrison were in the neighborhood.

“If he goes over the ridge,” said Strubell in a low tone, as all eyes were fixed on him, “he must see us.”

He did not pass over, but halted at the top and sat motionless on the bare back of his pony, evidently engaged in scanning every portion of the visible prairie. At this moment old Eph glanced at the animals, a short way behind them, and saw that his horse was in the act of rising. His forequarters were up, and his head raised, after the manner of his kind, when his master spoke sharply and he immediately sank back again.

The action of the steed was as singular as it was unfortunate, and for a minute everyone was sure the discovery had been made. But the action of the Apache to the south left the matter in doubt. He wheeled about and rode back to his comrades at an easier pace, but they did not gather around him, as they would have been quite sure to do if he had borne important news to them.

The result was that neither Bozeman nor the Texans knew whether the Apache had seen them or not—a state of doubt as trying as actual discovery.

The belief was that the action of the horse had not betrayed them, for, until the red men faded from view in the deepening gloom, nothing to show the contrary was observable.

The night promised to be favorable for the dangerous enterprise. It would be quite dark, the moon not appearing until late, there was no wind, and, in the stillness, the slightest sound could be heard for a long distance. If the Apaches knew nothing of the party behind the elevation, they would be likely to remain on their horses, whose tread could be detected long before they were visible, while the advance of old Eph was to be in such utter silence that even the wonderfully fine hearing of an Apache would avail him naught.

“I’m goin’ to start soon,” said the trapper, “and I want to know what’s to be said to Bell, if I get the chance to talk with him.”

“In the first place,” said Strubell, by way of reply, “Herbert is to fix the price of the ransom he’s willing to pay.”
