That night the breed squatted by his camp fire, too offended to smoke and wondering dumbly why his patron had left so soon and said so little, for this was a day to which he had looked forward for weeks. He did not dream that Clark was even that moment thinking of him as the private car clicked evenly over the rail joints on the way to the iron mines. And this indeed was the case, for in the first tide of the rush of gold seekers Clark had discerned the workings of an ancient rule. Always it had been gold which inflamed the human mind to endure to the uttermost. His imagination went back, and he saw the desperate influx heading for California, for Australia, for South Africa, that mob of adventurous spirits for whom there burned nightly over the hills the lambent promise of the morrow, strengthening and invigorating to further effort. He saw this mob lose itself in forest, mountain, plain and canyon, a wild-eyed herald of civilization. He saw roads and bridges, farms and villages take form along the trail it traversed, till, slowly but inexorably, the wilderness was conquered, and the sons of the pioneers sat in contentment under their own roof-tree in full possession of a wealth greater by far than that their ancestors had come to seek. But it was gold with its yellow finger that first beckoned the way. Next day, at the iron mine, he stood listening to the deep cough of the big crusher and the loose rattle of machine drills. A little on one side, and as yet unshaken by dynamite, was the knoll on which Wimperley and the rest had been told what they were sitting on, and he smiled at the recollection. Surveying the widening excavation, he reflected that here, after all, was the heart of the entire enterprise. In fifty--in a hundred years--the mine would still be unexhausted. It did not seem romantic like Fisette's vein of gold ore, this barren-looking upheaval, but to him the romance of a thing was in its potentiality and not its appearance, and it moved in his mind now that there was every reason for haste. Philadelphia was beginning to weary of capital expenditure, and demanded an output of steel rails at the earliest possible moment. Completing his round with a visit to Baudette's headquarter camp, he inspected train loads of pulp wood ready for the mills. The areas originally secured were nearly denuded and Baudette was forced further afield. The mills were doing and had always done well, but their profits were so instantly absorbed by allied and interlinked undertakings that Clark at times wondered whether he was asking one dollar to do too much. He reflected with a touch of surprise that the small company formed to supply St. Marys with water and light was, after all, the only one which from the first had actually disbursed dividends. But the rail mill would settle all that. Returning to the works he found a note on his desk that Townley, the chemist, would like audience. He sent for him.
