Had the Apache made a charge upon him, Herbert would have let fly without an instant’s hesitation. He was inclined to fire as it was; but, like the manly boy that he had become, he shrank from doing that which looked so much like a crime. Villainous as were the red men, he could not force himself to shoot one down in so heartless a fashion.

Besides, there was the possibility that the Indian did not know that anyone was on the elevation. Indeed, it might be said that the very appearance as described was evidence that he lacked such knowledge, for he had placed himself in a peril which one of his tribe would be sure to avoid. Herbert therefore decided to await more positive evidence of wrong intent before making any movement against the fellow.

His heart gave a quick throb when he discovered that the horseman was advancing. He heard the sound of his pony’s hoofs, followed by a more distinct outlining of both.

“I do believe I shall have to drop him,” thought Herbert, “and I wouldn’t wait any longer if I wasn’t afraid that it would bring the rest to the spot.”

It was this fear that restrained him. There were likely to be others near who would swarm thither at the report of his gun, and more than likely make him prisoner, or slay him before he could leap into the saddle and dash off.

Self-interest urged him to wait until the last moment.

He reasoned that it was impossible for the sharp-eyed warrior to see him, since he was still flat in the grass; he must have possessed wonderful acumen to make his way to the spot in the darkness.

“It all depends on you,” was Herbert’s decision; “if you keep your distance no one will be hurt, but one step more and there will be a missing Apache.”

The action of the latter was singular, for, after advancing a brief space, he again checked his pony and stood as motionless as before.

Nothing was clearer than that something was suspected at least by the red man to cause him to act in this manner. It may have been that his pony was the suspicious one, and the rider was debating with himself whether to explore further or give it up.
