He stood irresolutely an instant as if doubtful of the genuineness of this alleged business transaction.

It was as if the men feared he might attempt to overtake them; for despite the heavy loads on the burros they urged the beasts forward at their best pace, and Dick was still revolving the matter in his mind when they were a mile or more away.

"Well, it's no use for me to stand here tryin' to figure out whether they've given me this money or really mean to buy the rifle, for I've got to strike Antelope Spring between this time an' midnight. Now that there are ten dollars in my pocket, I'll be a pretty poor stick if I don't do it; but the sand-storm came mighty near windin' me up. It was the toughest thing I ever saw."

Then Dick set forward once more, toiling over the loose surface into which his feet sank three or four inches at every step; and when he finally stood on the firm soil east of this waste of shifting sand, it was two hours past noon.

As he had reckoned, there were more than thirty miles yet to be traversed; but the distance troubled him little.

He had in his possession that which would buy such knowledge and such drugs as his father might need, and he believed it would be almost a sin to rebel even in his thoughts against the labor which must be performed.

Now he advanced, whistling cheerily, with a long stride and a swinging gait that should have carried him over the trail at the rate of four miles an hour; and not until late in the afternoon did he permit himself to halt, and partake of the broiled venison.

Then he ate every morsel, and, the meal finished, said aloud with a low laugh of perfect content:—

"It's lucky I didn't bring any more; for I should eat it to a dead certainty, an' then I wouldn't be in as good trim for walkin'. Daddy always says that the less a fellow has in his stomach the easier he can get over the ground, and the poor old man never struck it truer."

After this halt of fifteen minutes Dick pressed forward without more delay until he came upon the settlement, at what time he knew not, but to the best of his belief it was hardly more than an hour past midnight.
