The boy, as you may suppose, lost no time in applying the glasses to his own eyes. Viewed through the magnifying medium, a startling moving-picture swung into focus.

Surrounding a big, covered wagon, of the prairie-schooner type, were from ten to a dozen wild-looking Mexicans, their straggling elf-locks crowned by high-peaked sombreros, and their serapes streaming out wildly about them, whipped into loose folds by the pace at which they rode. As Coyote Pete had said, there was little difficulty for any one who had seen him once, in recognizing Black Ramon de Barros. His magnificent black horse—the same on which he had escaped from the old mission—made him a marked man among a thousand. The wagon was drawn by six mules, and driven by a short, stocky, little Mexican. The horsemen seemed to act as escort for it. Evidently they had no fear of being observed by hostile eyes, for, as they advanced, they waved their rifles about their heads and yelled exultingly.

Fortunately for the party on the summit of the mesa, their stock was tethered on the opposite side of the formation to that on which the cavalcade was approaching. Thus, Black Ramon and his men could not see that the mesa was occupied. Jack caught himself wondering, though, how long it would be before, and what would happen when, they did.

"Have you got any plan in your head?" he asked, turning to Pete, as he laid the glasses down. But for once, to his dismay, the old plainsman seemed fairly stumped. The danger had come upon them so suddenly, so utterly unexpectedly, that it had caught them absolutely unprepared. They had not even a rifle with them on the mesa summit, and it was now too late to risk exposing themselves by descending for weapons. There was nothing to do, it seemed, but powerlessly to await what destiny would bring forth.

"You boys get back to the altar. You can act as company fer the profusser, and it will be a snug hiding-place in case of trouble," whispered Pete. "I wish to goodness we'd brought the stock up inside the mesa, and then those fellows might never have discovered we were here. I don't see how they can help it, as things are, though."

"They'll be bound to see our footmarks in the assembly hall," said Jack.

"Not bound to, lad," rejoined Pete. "You see, they may be only going to make this a watering-place fer their stock, and then press right on."

"Press right on across that rocky range yonder?"

"Hum," resumed Pete, "that's so. They couldn't very well get that wagin across that, could they?"

"Whatever do you suppose they've got a wagon for, at all?" asked Jack.
