Caption with print: Jay Cooke was a young banker from Ohio connected, in 1861, with a prominent banking house in Philadelphia. When the national government required vast sums to put and keep the Union forces in the field, he was among the first to respond. He located in the building Third Street, adjoining the Girard Bank, and organized the greatest advertising campaign ever known. Thoughout the war his agents scoured the entire north. He was able to supply the Federal cause, through those historic years, with money to the total of $1,500,000,000, at the rate of four and one-half per cent interest. For this service his firm was paid about one-sixteenth of one per cent.
