The animal whinnied whenever he opened his canteen to wet his parched throat, and somehow the sound made sympathetic Billie feel badly. After that he made it a point to step aside when he meant to quench his own thirst, just to avoid having Jupiter reproach him for being stingy. But it was not to be thought of for a minute, because the horse would exhaust the flask, and then not be a quarter satisfied, leaving him in a desperate state indeed.

Fortunately he had a little food with him, and this he proceeded to munch as he sat there behind the shelter of the horse.

He asked himself if the storm showed any signs of diminishing its fury; and after taking several estimates joyfully admitted that at least the wind was not so fierce as formerly.

This in itself was a glorious sign, for without the wind the sand could not fill the air; and by degrees it must settle down once more, so that one might breathe without feeling choked.

If that would only come about Billie felt that he could easily stand anything and everything else that was liable to happen. But should he have to endure that agony another few hours he believed he would go out of his mind.

Yes, there could not be any mistake about it, the storm was surely subsiding, and if conditions kept

on improving as they seemed to be doing now, by the time night set in fully it was going to be a thing of the past.

Billie even began to tell himself that he had no reason to complain, because it might have been a great deal worse. Except for the fact that he was compelled to keep a lone camp, away out there on that desert, and was tired almost to death, he could not say that his condition was in any way dreadful. Yes, he even believed he had plenty of water to quench his thirst; though it was evident that he would have to cut his allowance down to half rations, for his repeated sips had already caused the big canteen to feel considerably lighter.

Looking up toward the heavens when he found that night had really set in, he was surprised to find that he could not see a single star; and the moon was also absent. This must mean that there were clouds sailing over him, something quite out of the common where a desert is concerned; since rain seldom if ever is known to fall there; for if it did the desert would not long remain such, but blossom like the rose with fertility.

“Going to be a black night, in the bargain,” he grumbled; “seems like a fellow just has to rub up against all sorts of things when once they get started. But so far I hadn’t ought to complain. I only hope the other boys fare as well. Wonder how about them now; and if they got off the desert?
