this tankage is being constantly increased to meet the demands of the
producers.[1]

[Footnote 1: As showing the extent of the sea-coast transportation of
petroleum, we should mention that the statistics for 1884 show a total
of crude equivalent exported from the United States in that year,
equaling 16,661,086 barrels, of 51 gallons each. This is a daily average
of 42,780 barrels.]

The company is officially organized as follows: C.A. Griscom, President;
Benjamin Brewster, Vice President; John Bushnell, Secretary; Daniel
O'Day, General Manager; J.H. Snow, General Superintendent. Mr. Snow
was the practical constructor of the entire system, and the general
perfection of the work is mainly due to his personal experience, energy,
and careful supervision. His engineering assistants were Theodore M.
Towe and C.J. Hepburn on the New York line and J.B. Barbour on the
Pennsylvania lines.

The enterprise has been so far a great engineering success, and the oil
delivery is stated on good authority to be within 2 per cent. of the
theoretical capacity of the pipes. From a commercial standpoint, the
ultimate future of the undertaking will be determined by the lasting
qualities of wrought iron pipe buried in the ground and subjected to
enormous strain; time alone can determine this question.
