, who now knew all; and her mother was so taken up with religious devotions and brooding contemplation of her loss that she was not as active in her observation of Aileen's life as she might have been. Besides, Cowperwood and his mistress were more circumspect in their conduct than they had ever been before. Their movements were more carefully guarded, though the result was the same. Cowperwood was thinking of the West—of reaching some slight local standing here in Philadelphia, and then, with perhaps one hundred thousand dollars in capital, removing to the boundless prairies of which he had heard so much—Chicago, Fargo, Duluth, Sioux City, places then heralded in Philadelphia and the East as coming centers of great life—and taking Aileen with him. Although the problem of marriage with her was insoluble unless Mrs. Cowperwood should formally agree to give him up—a possibility which was not manifest at this time, neither he nor Aileen were deterred by that thought. They were going to build a future together—or so they thought, marriage or no marriage. The only thing which Cowperwood could see to do was to take Aileen away with him, and to trust to time and absence to modify his wife's point of view.
This particular panic, which was destined to mark a notable change in Cowperwood's career, was one of those peculiar things which spring naturally out of the optimism of the American people and the irrepressible progress of the country. It was the result, to be accurate, of the prestige and ambition of Jay Cooke, whose early training and subsequent success had all been acquired in Philadelphia, and who had since become the foremost financial figure of his day. It would be useless to attempt to trace here the rise of this man to distinction; it need only be said that by suggestions which he made and methods which he devised the Union government, in its darkest hours, was able to raise the money wherewith to continue the struggle against the South. After the Civil War this man, who had built up a tremendous banking business in Philadelphia, with great branches in New York and Washington, was at a loss for some time for some significant thing to do, some constructive work which would be worthy of his genius. The war was over; the only thing which remained was the finances of peace, and the greatest things in American financial enterprise were those related to the construction of transcontinental railway lines. The Union Pacific, authorized in 1860, was already building; the Northern Pacific and the Southern Pacific were already dreams in various pioneer minds. The great thing was to connect the Atlantic and the Pacific
