Below them lay a wild panorama of broken country, through which ran Green River to plunge deep into the winding mazes of Labyrinth Canyon, away to the southward. Away to the west, beyond the San Rafael Swell, rose the Wasatch Mountains; being much nearer than the Rockies to the eastward, and, therefore, looking nearly as lofty. To the north were Desolation Canyon and the Roan Cliffs, the latter rising brown and bleak at the southern boundary of the Ute Reservation. To the south of mighty Colorado, rolling through the dark depths of canyons which seemed to sink deep into the bowels of the earth. Farther to the south, beyond the Fremont, which as yet could not be seen, Mount Pennell lifted its snow-capped summit eleven thousand feet in the air. Mount Pennell was in the very heart of the mountain region in which the last of the Destroying Angels had found homes. "Professor!" said Frank, speaking gently. "Ha! ha!" muttered the inventor, as he threw over a lever and sent the _Eagle_ scooting in a breathless sweep toward the earth. "She is like a bird! Up or down, to the right or left, she will sail in any direction." "Professor!" "Don't bother me now--don't bother me!" he almost snarled. "I was a fool to take you along! I should have retained all the honor for myself. Now you will share it. It will be published all over the world that you accompanied Professor Scudmore on his trial trip in his wonderful air ship." He glared at them a moment, as if he longed to cast them overboard, and then the handling of the craft claimed his entire attention. "How do yez loike it, Frankie, me b'y?" asked Barney, with a sly nudge at his companion. "It is decidedly uncomfortable." "Phwat shall we do--jump th' son-av-a-goon at wance?" "Nothing of the sort. We will keep still, as if we are quite satisfied and content. I will draw him into conversation when I think it proper, and he may be brought round all right." So the boys remained silent and passive, one of them constantly watching Scudmore, so that they might not be taken by surprise, in case he took a fancy to attack them. He continued to mutter and talk to himself, now and then laughing in a way that was not pleasant to hear. The boys fell to wondering what the various bundles contained. Opening one of them, covertly, they found it was a supply of dried beef. "Great shmoke!" gasped Barney. "He has laid in a supply av provisions to larrust a wake!" Frank nodded. "It looks that way; but these things are not all provisions. See there at his side--one of those bundles contains firearms, for you may see the muzzles of two rifles protruding. I fancy the bundle next to that contains ammunition." "Whoy, thot's enoogh to shtock a small arumy, Frankie!" "A man like Professor Scudmore has very little notion as to what he needs or desires, and so he is liable to obtain four or five times what is necessary."
