of the case. Still, he hardly liked the idea of being compelled to shed human blood just because of a horse like his Jupiter. Secretly he hoped that if there did come along any necessity for this sort of thing, his companions would accept some of the burden of responsibility, since they did not seem to care as much as he did.

Donald altered his plans more or less, after this plain warning. Now that they actually knew there were thieving Indians around, they could not afford to take any chances of losing their horses.

Accordingly the animals, as well as Bray the pack mule, were brought in closer to the tent. They had been given ample time to procure a supper, and should rest contented during the remainder of the night.

It was a toss-up between the two experienced cowboys as to which should take the first watch. Billie, quite satisfied to see them so eager to sit up, did all he knew how to settle the matter.

“Here, let me be the umpire, and hold these two straws in my hand,” he remarked, complacently; “now, one of them is just a mite shorter than the other; and whoever gets the short one is to play sentry first watch, hear that. You draw, Donald!”

Thereupon the party indicated proceeded to do as he was directed, and with the utmost unconcern, as though it mattered not at all to him what his luck might be.

“And you’re on deck the first thing!” announced Billie, exultantly, as he held up the remaining straw, so that they could all see it was longer than the one Donald had selected.

“Great luck, that!” the picked vidette remarked, laughingly; “for I was bound to take first choice anyhow, no matter what Ad said. But you closed him up by your little dodge, Billie, and for that thanks. Are you thinking of going inside, and getting your forty winks right now, fellows?”

They said they had intentions along those same lines, if he thought he could manage things without their help; at which Donald pretended to chase the pair to cover; and then remarked that he would find a good vantage place, where he might stand out his spell as guardian of the camp.

Perhaps Billie may not have been altogether free from anxieties as he composed himself under his blanket on that same night. The fact that hostile Indians were hovering around, with the intention of stealing their valuable mounts, caused him to feel a certain amount of nervousness. He feared that he would not be able to go to sleep as easily as was his custom; and that during the entire term of Donald’s watch he must just lie there, thinking and listening.
