With all these reflections fresh in mind, Mr. Rockefeller again bent over a map of the refining interests of the United States. Here was the world he sighed to conquer. If we may suppose him to have begun his campaign as a great general with whom he has many traits in common—the First Napoleon—used to begin his, by studding a map with red-headed pegs marking the points he must capture, Mr. Rockefeller’s chart would have shown in and around Boston perhaps three pegs, representing a crude capacity of 3,500 barrels; in and around New York fifteen pegs, a capacity of 9,790 barrels; in and around Philadelphia twelve pegs, a capacity of 2,061 barrels; in Pittsburg twenty-two pegs, a capacity of 6,090 barrels; on the creek twenty-seven pegs, a capacity of 9,231 barrels.[42] His work was to get control of this multitude of red pegs and to fly above them the flag of what the irreverent call the “holy blue barrel.”[43] Some time in the summer of 1874, after it had become certain that Colonel Potts’s plan for an equalisation of oil freights would be carried out, Mr. Rockefeller wrote to his former colleague in the South Improvement Company, W. G. Warden, of Philadelphia, telling him he wanted to talk over the condition of the oil business with him, and inviting him to bring Charles Lockhart, of Pittsburg, to that Mecca of American schemers, Saratoga, for a conference with him and Mr. Flagler. Mr. Warden hesitated. He had been much abused for his relation with the South Improvement Company. He had seen the National Refiners’ Association fail. He had begun to feel a distaste for combination. Besides, he was doing very well in Philadelphia. However, after some hesitation, he and Mr. Lockhart went to Saratoga. The four gentlemen breakfasted together and later strolled out to a pavilion. Here they discussed again, as they had nearly three years before, when they prepared the South Improvement assault, the condition of the oil business. [Illustration: GEORGE H.
