He made no complaint. On the division he took hold with new energy and bent his faculties on the operating problems. At Marion's he saw Dicksie at intervals, and only to fall more hopelessly under her spell each time. She could be serious and she could be volatile and she could be something between which he could never quite make out. She could be serious with him when he was serious, and totally irresponsible the next minute with Marion. On the other hand, when McCloud attempted to be flippant, Dicksie could be confusingly grave. Once when he was bantering with her at Marion's she tried to say something about her regret that complications over the right of way should have arisen; but McCloud made light of it, and waved the matter aside as if he were a cavalier. Dicksie did not like it, but it was only that he was afraid she would realize he was a mere railroad superintendent with hopes of a record for promotion quite blasted. And as if this obstacle to a greater reputation were not enough, a wilier enemy threatened in the spring to leave only shreds and patches of what he had already earned. The Crawling Stone River is said to embody, historically, all of the deceits known to mountain streams. Below the Box Canyon it ploughs through a great bed of yielding silt, its own deposit between the two imposing lines of bluffs that resist its wanderings from side to side of the wide valley. This fertile soil makes up the rich lands that are the envy of less fortunate regions in the Great Basin; but the Crawling Stone is not a river to give quiet title to one acre of its own making. The toil of its centuries spreads beautifully green under the June skies, and the unsuspecting settler, lulled into security by many years of the river's repose, settles on its level bench lands and lays out his long lines of possession; but the Sioux will tell you in their own talk that this man is but a tenant at will; that in another time and at another place the stranger will inherit his fields; and that the Crawling Stone always comes back for its own. This was the peril that Glover and McCloud essayed when they ran a three-tenths grade and laid an eighty-pound rail up two hundred and fifty miles of the valley. It was in local and exclusive territory a rich prize, and they brought to their undertaking not, perhaps, greater abilities than other men, but incomparably greater material resources than earlier American engineers had possessed.
