Although a practical monopoly in many parts of the interior had been acquired at a tolerably early date, there continued to be active competition in all branches of the petroleum business until 1884, when the war of rates, which had been waged for some time with a formidable Canadian competitor, the Tidewater Company, ceased, an alliance being formed between the rivals. From that time the Standard Oil Trust has held a practical monopoly over the greater part of the country. It has introduced new economies in the machinery of refining, has found profitable uses for naphtha and other waste products, and has vastly increased its output and the machinery of distribution. Not content with controlling the market for crude oil, it has during the last few years obtained the possession of larger and larger portions of the oil-producing country, forming companies to acquire mining rights, sink wells, and oust the private producers from whom it had previously been content to purchase the raw material at their own prices. Bearing in mind the fact that the actual unification of businesses took place a good many years before the formation of the Trust, there is nothing in the account given above inherently inconsistent with the following explanation afforded by the Standard Oil Trust of their proceedings:-- "The Standard Oil Trust offers to prove by various witnesses that the disastrous condition of the refining business, and the numerous failures of refiners prior to 1875, arose from imperfect methods of refining, want of co-operation among refiners, the prevalence of speculative methods in the purchase and sale of both crude and refined petroleum, sudden and great reductions in price of crude, and excessive rates of freight; that these disasters led to co-operation and association among the refiners, and that such association and co-operation, resulting eventually in the Standard Oil Trust, has enabled the refiners so co-operating to reduce the price of petroleum products, and thus benefit the public to a very marked degree."[132] So far as this furnishes an explanation of the motives leading to the earlier growth of the Company, the consolidation of rival companies, no doubt it contains a considerable element of truth. The Standard Oil Trust, however, differs from most others in that it was not directly formed by the union of a number of leading rival businesses, but was merely a reorganisation upon a firmer basis of a single complex business. The motive of self-protection, though it might be operative in the early history of the Company, cannot be adduced as the true motive of the formation of the Trust. Since the claim of the Standard Oil Trust to be a public benefit rests upon the fall of price to the customer, resulting from the various economies and improvements adopted by the Trust, it may be well to append a diagram showing the actual fall of prices during the twenty years 1870 to 1890.
