Ohio, Indiana, Illinois, Kansas, Oklahoma, Texas, California, and other states in turn became the scene of the same exciting and adventurous events that had followed the discovery of oil in Pennsylvania.

The Standard promptly extended its pipe lines into these new areas, but other great companies also took part in the development.
These companies, such as the Gulf Refining Company and the Texas Refining Company, have their gathering pipe lines, their great trunk lines, their marketing stations, and their export trade, like the Standard; the Pure Oil Company has its tank cars, its tank ships, and its barges on the great rivers of Europe.

The ending of the rebate system has stimulated the growth of independents, and the production of crude oil and the market demand in a thousand directions has increased the business to an extent which is now far beyond the ability of any one corporation to monopolize.

The Standard interests refine perhaps something more than fifty per cent of the crude oil produced in this country.

But in recent years, Standard Oil has meant more than a corporation dealing in this natural product.
