A significant development in the region was the tendency among many of the oil men to combine different branches of the business. Several large producers conducted shipping agencies for handling their own and other people’s oil. The firm of Pierce and Neyhart was a prominent one carrying on this double business in the sixties and early seventies. J. J. Vandergrift, who has been mentioned already as one of the first men to take hold of the transportation problem, early became interested in production. As soon as the pipe-line was demonstrated to be a success he began building lines. He also added to his interests a large refinery, the Imperial of Oil City. Captain Vandergrift by 1870 produced, transported and refined his own oil as well as transported and refined much of other people’s. It was a common practice for a refinery in the Oil Regions to pipe oil directly to its works by its own line, and in 1872 one refinery in Titusville, the Octave, carried its refined oil a mile or more by pipe to the railroad. Although most of the refineries at this period sold their products to dealers and exporters, the building up of markets by direct contact with new territory was beginning to be a consideration with all large manufacturers. The Octave of Titusville, for instance, chartered a ship in 1872 to load with oil and send in charge of its own agent into South American ports. The odds against the oil men in developing the business had not been merely physical ones. There had been more than the wilderness to conquer, more than the possibilities of a new product to learn. Over all the early years of their struggle and hardships hovered the dark cloud of the Civil War. They were so cut off from men that they did not hear of the fall of Sumter for four days after it happened, and the news for the time blotted out interest even in flowing wells. Twice at least when Lee invaded Pennsylvania the whole business came to a stand-still, men abandoning the drill, the pump, the refinery to make ready to repel the invader. They were taxed for the war—taxes rising to ten dollars per barrel in 1865—one dollar on crude and twenty cents a gallon on refined (the oil barrel is usually estimated at forty-two gallons). They gave up their quota of men again and again at the call for recruits, and when the end came and a million men were cast on the country, this little corner of Pennsylvania absorbed a larger portion of men probably than any other spot in the United States. The soldier was given the first chance everywhere at work, he was welcomed into oil companies, stock being given him for the value of his war record. There were lieutenants and captains and majors—even generals—scattered all over the field, and the field felt itself honoured, and bragged, as it did of all things, of the number of privates and officers who immediately on disbandment had turned to it for employment.
