"No, not for money or gratitude or any other argument they can bring to bear," he said to himself, and thereupon fell asleep with the mistaken notion that he had definitely pushed the temptation aside for good and all. VI The Twig It is said that the flow of a mighty river may owe its most radical change in direction to the chance thrusting of a twig into the current at some critical instant in the rise or fall of the flood. To the reincarnated Smith, charting his course upon the conviction that his best chance of immunity lay in isolation and a careful avoidance of the peopled towns, came the diverting twig in this wise. On the second morning following the unofficial talk with Bartley Williams in the iron-sheeted headquarters office at the dam, a delayed consignment of cement, steel, and commissary supplies was due at the side-track a mile below the camp. Perkins, the timekeeper, took the telephone call from Brewster giving notice of the shipment, and started the camp teams to meet the train, sending a few men along to help with the unloading. Later, he called Smith in from the quarry and gave him the invoices covering the shipment. "I guess you'd better go down to the siding and check this stuff in, so that we'll know what we're getting," was his suggestion to the general utility man; and Smith put the invoices into his pocket and took the road, a half-hour or more behind the teams. When the crookings of the tote-road let him get his first sight of the side-track, he saw that the train was already in and the mixed shipment of camp supplies had been transferred to the wagons. A few minutes sufficed for the checking, and since there was nothing more to be done, he sent the unloading gang back to camp with the teams, meaning to walk back, himself, after he should have seen the car of steel and the two cars of cement kicked in at the upper end of the side-track. While he was waiting for the train to pull up and make the shift he was commenting idly upon the clumsy lay-out of the temporary unloading yard, and wondering if Williams were responsible for it. The siding was on the outside of a curve and within a hundred yards of the river bank. There was scanty space for the unloading of material, and a good bit of what there was was taken up by the curving spur which led off from the siding to cross the river on a trestle, and by the wagon road itself, which came down a long hill on the south side of the railroad and made an abrupt turn to cross the main track and the siding fairly in the midst of things.
