“Another thing,” ventured the pleased Billie; “we can fill up our canteens fresh before we start in the morning; and make the ponies drink all they want; for if we have to cross that sand stretch, why, the chances are it’ll be a dry job, and we’ll be glad we stopped over night here, see if we don’t.” As it was settled that they should go no further that day, the three lads started to get the camp in shape. First they found a place where the animals could be staked out, so that they might pick up some of the grass which seemed only to grow around the spring hole, as is often the case in this country of the Southwest, where arid wastes and rocky regions predominate. Then the tent was erected, and the fireplace made; so that in a short time things began to take on the appearance of a regular camp. Billie was in his glory at such a time. He knew that soon there would be a delicious aroma filling the air, as they started to get supper ready; and that always tickled him greatly. As the war horse prances when he whiffs the smoke of battle, so Billie became animated as soon as he caught the first scent of onions frying, or coffee boiling; as he would himself say, “simply because he was built that way, and couldn’t help it.” And so the second day of their journey across the wild country that lay between the Red Spar Mine and the village of the Zuni Indians, came to an end, with all well. Billie could not see that they had any reason to complain, as, seated on the ground, tailor fashion, with his legs curled under him, and a pannikin of venison, together with fried onions and beans, in his lap, his tin cup of fragrant coffee resting close beside him, he started in to appease the ferocious appetite that had been worrying him for half an hour and more. Why, the future looked as bright as that glowing sky that marked the going down of the sun in the west. For it did not lie in their power to roll back the curtains of the future for even one day, and see what lay awaiting them on the morrow. Perhaps Billie might not have felt so light-hearted had he known what was coming; but after all it was just as well. CHAPTER X. LOST IN THE SAND STORM. They passed a fairly comfortable night, in camp there by the spring. Nothing occurred to cause an alarm, though Donald and Adrian would not allow the camp to go unguarded, and took turns playing sentry. Billie, too, was quite anxious to try his hand at the job; and they had to let him have a turn; but not feeling any confidence that the fat boy would stay awake Donald made sure to keep one eye open. And sure enough, later on he found Billie calmly sleeping, with his gun across his knees.
