deducting any commission allowed, the road realised from it the same amount of profits as it did from the Standard trade. The points in the agreement were embodied in a letter from William Rockefeller to Mr. Scott. This letter and the answer declaring the arrangement to be satisfactory to the company are both dated October 17.[57] Four months later Mr. Rockefeller was able to take another step of great advantage. He was able to put into operation the system of drawbacks on other people’s shipments which the South Improvement Company contracts had provided for, and which up to this point he seems not to have been securely enough placed to demand. There were no bones about the request now. Mr. O’Day, the general manager of the American Transfer Company, a pipe-line principally in Clarion County, Pennsylvania, which, including its branches, was from eighty to 100 miles in length, a company now one of the constituents of the United Pipe Line, wrote to Mr. Cassatt: “I here repeat what I once stated to you, and which I wish you to receive and treat as strictly confidential, that we have been for many months receiving from the New York Central and Erie Railroads certain sums of money, in no instance less than twenty cents per barrel on _every barrel of crude oil carried by each of these roads_.” Continuing, Mr. O’Day says: “Co-operating as we are doing with the Standard Oil Company and the trunk lines in every effort to secure for the railroads paying rates of freight on the oil they carry, I am constrained to say to you that in justice to the interests I represent we should receive from your company at least twenty cents on each barrel of crude oil you transport.... In submitting this proposition I find that I should ask you to let this date from November 1, 1877, but I am willing to accept as a compromise (which is to be regarded as strictly a private one between your company and ours) the payment by you of twenty cents per barrel on all crude oil shipments commencing with February 1, 1878.”[58] Mr. Cassatt complied with Mr. O’Day’s request. In a letter to the comptroller of the road he said that he had agreed to allow this commission after having seen the receipted bills, showing that the New York Central allowed them a commission of thirty-five cents a barrel, and the Erie Railroad a commission of twenty cents a barrel on Bradford oil and thirty cents on all other oils. Thus the Standard Oil Company, through the American Transfer Company, received, in addition to rebates on its own shipments, from twenty to thirty-five cents drawback a barrel on all crude oil which was sent over the trunk lines by other people as well as by itself.[59]
