We hurried more, at Scout pace, which is trotting and walking mixed. And next-- "Now they've got on the burros," said Fitz. "There aren't any sole tracks and the burros' hoofs dig deeper." The fellows surely were making time. I could imagine how they kicked and licked Sally and Apache, to hasten. And while we hastened, too, we must watch the signs and be cautious that we didn't overrun or get ambushed. Where the sun shone we could tell that the sign was still an hour or more old, because the edges of the hoof-marks were baked hard; and sticks and stones turned up had dried. And in the shade the bits of needles and grass stepped on had straightened a little. And there were other signs, but we chose those which we could read the quickest. (Note 33.) We were high up among cedars and bushes, on a big mesa. There were cattle, here, and grassy parks for them. Most of the cattle bore a Big W brand. The trail the cattle had made kept dividing and petering out, and we had to pick the one that the burros took. The fellows were riding, still, but not at a trot so much. Maybe they thought that we had been left, by this time. Pretty soon the burros had been grabbing at branches and weeds, which showed that they were going slower, and were hungry; and the fellows had got off and were walking. The sun was high and the air was dry, so that the signs were not so easy to read, and we went slower, too. The country up here grew open and rocky, and at last we lost the trail altogether. That was bad. The general and I circled and scouted, at the sides, and Fitz went on ahead, to pick it up beyond, maybe. Pretty soon we heard him whistle the Elks' call. He had come out upon a rocky point. The timber ended, and before and right and left was a great rolling valley, of short grasses and just a few scattered trees, with long slopes holding it like a cup. The sun was shining down, and the air was clear and quivery. "I see them," said Fitz. "There they are, General--in a line between us and that other point of rocks." Hurrah! This was great news. Sure enough, when we had bent low and sneaked to the rocks, and were looking, we could make out two specks creeping up the sunshine slope, among the few trees, opposite. That was good, and it was bad. The thieves were not a mile ahead of us, then, but now we must scout in earnest. It would not do for us to keep to the trail across that open valley. Some fellows might have rushed right along; and if the other fellows were sharp they would be looking back, at such a spot, to watch for pursuers. So we must make a big circuit, and stay out of sight, and hit the trail again on the other side. We crept back under cover, left a "warning" sign on the trail (Note 34), and swung around, and one at a time we crossed the valley higher up, where it was narrower and there was brush for cover. This took time, but it was the proper scouting; and now we hurried our best along the other slope to pick up the trail once more.
