While these things were going on, Paul Carhart was riding westward at a hot gallop with Dimond close behind. It was shortly after sunset that he reined up on the crest of the eastern ridge and looked out over the La Paz. The barren valley was flooded with light. The yellow slopes were delicately tinted rose and violet, the rock pillars stood out black and sharply defined, the western hills formed a royal purple barrier to the streams of color; and through this glowing scene extended the square-jointed trestle, unmistakably the work of man where all else was from another hand. Never in the progress of this undertaking which we have been following across the plains had the contrast been so marked between the patient beauty of the old land and the uncompromising ugliness of the structure which Paul Carhart was carrying into and through it. And yet the chief,—an intelligent, educated man, not wanting in feeling for the finer side of life,—though he took in the wonders of the sunset, looked last and longest at the trestle and the uncompleted bridge. Then he rode down, glancing, in his quizzical way, at the camp, which had been moved back behind a knoll, at the piles of stone and timber, at the corral, and at the groups of idle, gloomy workmen.

Fortunately the chief was prepared for surprises. News that the trestle had been burned to the ground would have drawn no more than a glance and a nod from him. His mind had not been idle during the ride. He knew that the strongest defence partakes of an offensive character, and he had no notion of sitting back to await developments. Of several sets of plans which he had been considering, one was so plainly the simplest and best that he was determined to try it. It involved a single daring act, a sort of raid, which it would be necessary to carry through without a vestige of legal authority. But this feature of it disturbed him very much less than a mere casual acquaintance with this quiet gentleman might have led one to suppose. Perhaps he had, like the red-blooded Tiffany, a vein of “Scotch-Irish” down in the depths of his nature which could on occasion be opened up.

“The cigarette dropped from Antonio’s unnerved fingers.”

After looking out for the comfort of John Flint, and after conferring with Haddon and going thoroughly over the ground, Carhart sent for Dimond.

“How much more are you good for?” he asked.

Dimond grinned. “For everything that’s going,” he replied.

“Good. Do you know where the H. D. & W. is building down, a dozen or fifteen miles north of here?”

“I guess I can find it,” said Dimond.

And with a fresh horse and a man or two, and with certain specific instructions, Dimond rode north shortly after nightfall of that same day. At eight in the morning he was back, hollow-eyed but happy. And Paul Carhart, when Dimond had reported, was seen to smile quietly to himself.
