The faces of Strubell and Lattin showed signs of the stirring conversation, but, as the boys anticipated, they were silent as to the theme.

“We must make a change in our course,” said the elder, who immediately turned the head of his pony to the westward, in the direction of the hills among which they had spent the previous night. It was near noon, and the major part of the day was gone, when they reached the rougher section where the Texans said the camp was to be made.

They showed their usual good judgment in the selection of a favorable site, for it was near another running stream, larger than the previous one, though the current was roiled and lukewarm. They might count themselves fortunate, however, that they were able to find water at all; for thirst has caused the death of untold thousands of cattle on the vast plains of Texas, and brought great suffering to those who have ventured not alone upon the Llano Estacado, but in other localities where moisture is almost unknown.

The pack horses were unloaded, saddles and bridles removed, and the ponies allowed to crop the scanty grass. It was too early for the regular evening meal, but considerable fuel was gathered; and, much sooner than there seemed to be any need for it, a fire was started, the smoke from which rose vertically, and was of so dark a color that it must have been visible for a long distance across the plain.

During all this time the three horsemen in the eastern horizon were not forgotten. The glasses were often turned thither, and there could be no doubt that Rickard and his companions were keeping our friends in sight. Evidently they were determined that they should not be lost.

The use of spy glasses has never been common among the cowmen, who are generally gifted with such keen eyesight that they scorn everything in the nature of artificial help. Counting upon this fact, it was not unlikely that Rickard believed that, by hovering on the line of invisibility, he would escape attention, or at least suspicion, on the part of the Texans. Had he known of the field glasses, he must have made an important change in his programme.

The fact that our friends were without a particle of food did not cause them concern. They were not likely to suffer from starvation, for, beside the stray cattle that they were warranted in using in an emergency (always holding themselves ready to reimburse the owner when it could be done), there were antelope and other animals to be found among the hills.

But Lattin stated that, unless some kind of game would be accommodating enough to come forward and offer itself as a sacrifice to their needs, they would content themselves with a good cup of coffee around, making up for the light meal when morning should come.

When the sun sank behind the hills, Rickard and his party became invisible to the naked eye. The supposition might have been that they had withdrawn and would be seen no more, but for the story told by the field glasses. Under their power it was discovered that the scamps had dismounted near a small arroya or natural depression, and compelled their animals to lie down. Seating themselves at the same time on the grass, they filled too small an angle for the unassisted eye to note them across the intervening space.
