Thomas A. Scott, president of the Pennsylvania Railroad established the South Improvement Company in the fall of 1871. A group representing the trunk railroad interests and oil refinery interests met in New York in late November, 1871, to discuss the creation of the company. Included in this meeting were
William Henry Vanderbilt and John D. Rockefeller. The scheme was intended to benefit both the railroads and major refiners, notably those controlled by Rockefeller through secret
rebates. Rockefeller had earlier merged several of the
Cleveland area refineries and issued 2,000 shares of stock, of which 900 were controlled by Rockefeller and his partners. Rockefeller then started negotiations to collude with the three major railroads running through Cleveland: the Erie Railroad, the Pennsylvania Railroad, and the New York Central Railroad. The result of these secret negotiations were as follows: (1) The official rate per barrel from Cleveland to New York would be $2.56, but South Improvement would receive a $1.06 rebate; (2) The railroads would also pay South Improvement $1.06 per barrel of oil shipped that was not produced by South; (3) The railroads would also give reports of the shipping destinations, costs, and dates of all of South's competitors; (4) The commerce would be divided evenly among the railroads, with a double share going to Pennsylvania Railroad; and (5) South would provide tank cars and loading facilities. The secret concessions would have helped lessen the "vicious" competition among the railroad lines by giving a steady, standardized flow of commerce. Shares of the South Improvement Company were allocated to interests in the oil refining cities as follows: Pittsburgh received 485, Philadelphia received 505, Cleveland received 720, and New York received 180 (represented by
Jabez A. Bostwick). Peter H. Watson, as president of the South Improvement Company, received 100 shares. Since both Bostwick and Watson were secretly allied with Standard Oil, Rockefeller kept control of the company from the Pennsylvania oil refiners and Pennsylvania Railroad interests.
Charles Pratt of New York and
John Dustin Archbold and Jacob Vandergrift of the oil regions had refused to join and so did not receive shares. Rockefeller used the company as a tool to force Cleveland refiners to further consolidate. Between mid-February and mid-March 1872, John D. Rockefeller and Henry Flagler bought twenty-three companies, eighteen of which were oil refineries, and all but one of them were located in Cleveland. Historians would come to call this the "Cleveland Massacre." An independent refiner who thought he could survive found that when he went to borrow money, all the Cleveland banks were in Standard Oil's pocket. Rockefeller had offered every important Cleveland banker a chance to buy Standard Oil stock, ensuring the welfare of the Standard Oil company. ==Dissolution==
