From the book:Can you make out any sign of the mesa yet, Pete? The speaker, a sun-bronzed lad of about seventeen, mounted on a bright bay pony with a white-starred forehead, drew rein as he spoke. Shoving back his sombrero, he shielded his eyes from the shimmering desert glare with one hand and gazed intently off into the southwest. "Nope; nary a speck, so fur. Queer, too; we ought to be seein' it by now." Coyote Pete, as angular, rangy and sinewy as ever, gazed as intently in the same direction as the lad, Jack Merrill, himself. The pause allowed the remainder of the party to ride up. There was Ralph Stetson, a good deal browner and sturdier-looking than when we encountered him last in "The Border Boys on the Trail"; Walt Phelps, the ranch boy, whose blazing hair outrivaled the glowing sun; and the bony, grotesque form of Professor Wintergreen, preceptor of Latin and the kindred tongues at Stonefell College, and amateur archaeologist. Lest they might feel slighted, let us introduce also, One Spot, Two Spot and Three Spot, the pack burros.
