The first intimation that the Oil Region had that Mr. Rockefeller was pushing another combination was in March of 1875, when it was announced that an organisation of refiners, called the Central Association, of which he was president, had been formed. Its main points were that if a refiner would lease to the association his plant for a term of months he would be allowed to subscribe for stock of the new company. The lease allowed the owner to do his own manufacturing, but gave Mr. Rockefeller’s company “irrevocable authority” to make all purchases of crude oil and sales of refined, to decide how much each refinery should manufacture, and _to negotiate for all freight and pipe-line expenses_. The Central Association was a most clever device. It furnished the secret partners of Mr. Rockefeller a plausible proposition with which to approach the firms of which they wished to obtain control. Little as the Oil Regions knew of the real meaning of the Central Association, the news of its organisation raised a cry of monopoly, and the advocates of the new scheme felt called upon to defend it. The defense took the line that the conditions of the trade made such a combination of refineries necessary. Altogether the ablest explanation was that of H. H. Rogers, of Charles Pratt and Company, to a reporter of the New York Tribune: “There are five refining points in the country,” said Mr. Rogers, “Pittsburg, Philadelphia, Cleveland, the Oil Regions and New York city. Each of these has certain local advantages which may be briefly stated as follows: Pittsburg, cheap oil; Philadelphia, the seaboard; Cleveland, cheap barrels, and canal as well as railroad transportation; the Oil Regions, crude oil at the lowest figure; and all the products of petroleum have the best market in New York city. The supply of oil is three or four times greater than the demand.[47] If the oil refineries were run to their full capacity, the market would be overstocked. The business is not regular, but spasmodic. When the market is brisk and oil is in demand, all the oil interests are busy and enjoy a fair share of prosperity. At other times, the whole trade is affected by the dullness. It has been estimated that not less than twenty millions of dollars are invested in the oil business. It is therefore to the interest of every man who has put a dollar in it to have the trade protected and established on a permanent footing. Speculators have ruined the market. The brokers heretofore have been speculating upon the market with disastrous effects upon the trade, and this new order of things will force them to pursue their legitimate calling, and realise their profits from their industry and perseverance. Two years ago an attempt was made to organise an oil refiners’ association, but it was subsequently abandoned. There was no cohesion of interests, and agreements were not kept. The movement at the present time is a
