that he envisioned for the nascent oil industry. In the early years, John D. Rockefeller dominated the combine; he was the single most important figure in shaping the new oil industry. He quickly distributed power and the tasks of policy formation to a system of committees, but always remained the largest shareholder. Authority was centralized in the company's main office in Cleveland, but decisions in the office were made cooperatively. The company grew by increasing sales and through acquisitions. After purchasing competing firms, Rockefeller shut down those he believed to be inefficient and kept the others. In a seminal deal, in 1868, the Lake Shore Railroad, a part of the New York Central, gave Rockefeller's firm a going rate of one cent a gallon or forty-two cents a barrel, an effective 71% discount from its listed rates in return for a promise to ship at least 60 carloads of oil daily and to handle loading and unloading on its own. Smaller companies decried such deals as unfair because they were not producing enough oil to qualify for discounts. Standard's actions and secret transport deals helped its kerosene price to drop from 58 to 26 cents from 1865 to 1870. Rockefeller used the Erie Canal as a cheap alternative form of transportation—in the summer months when it was not frozen—to ship his refined oil from Cleveland to New York City. In the winter months, his only options were the three trunk lines—the Erie Railroad and the New York Central Railroad to New York City, and the Pennsylvania Railroad to Pittsburgh and Philadelphia. Competitors disliked the company's business practices, but consumers liked the lower prices. Standard Oil, being formed well before the discovery of the Spindletop oil field (in Texas, far from Standard Oil's base in the Midwest) and a demand for oil other than for heat and light, was well placed to control the growth of the oil business. The company was perceived to own and control all aspects of the trade. South Improvement Company In 1872, Rockefeller joined the South Improvement Co. which would have allowed him to receive rebates for shipping and drawbacks on oil his competitors shipped. But when this deal became known, competitors convinced the Pennsylvania Legislature to revoke South Improvement's charter. No oil was ever shipped under this arrangement. Using highly effective tactics, later widely criticized, it absorbed or destroyed most of its competition in Cleveland
