It would be impossible to indicate fully how subtle were the material changes which these years involved—changes so gradual that they were, like the lap of soft waters, unnoticeable. Considerable—a great deal, considering how little he had to begin with—wealth was added in the next five years. He came, in his financial world, to know fairly intimately, as commercial relationships go, some of the subtlest characters of the steadily enlarging financial world. In his days at Tighe’s and on the exchange, many curious figures had been pointed out to him—State and city officials of one grade and another who were “making something out of politics,” and some national figures who came from Washington to Philadelphia at times to see Drexel & Co., Clark & Co., and even Tighe & Co. These men, as he learned, had tips or advance news of legislative or economic changes which were sure to affect certain stocks or trade opportunities. A young clerk had once pulled his sleeve at Tighe’s. “See that man going in to see Tighe?” “Yes.” “That’s Murtagh, the city treasurer. Say, he don’t do anything but play a fine game. All that money to invest, and he don’t have to account for anything except the principal. The interest goes to him.” Cowperwood understood. All these city and State officials speculated. They had a habit of depositing city and State funds with certain bankers and brokers as authorized agents or designated State depositories. The banks paid no interest—save to the officials personally. They loaned it to certain brokers on the officials’ secret order, and the latter invested it in “sure winners.” The bankers got the free use of the money a part of the time, the brokers another part: the officials made money, and the brokers received a fat commission. There was a political ring in Philadelphia in which the mayor, certain members of the council, the treasurer, the chief of police, the commissioner of public works, and others shared. It was a case generally of “You scratch my back and I’ll scratch yours.” Cowperwood thought it rather shabby work at first, but many men were rapidly getting rich and no one seemed to care. The newspapers were always talking about civic patriotism and pride but never a word about these things. And the men who did them were powerful and respected.
