Professor Silliman made his report to the Pennsylvania Rock-Oil Company in 1855, but it was not until the spring of 1858 that a representative of the organisation, which by this time had changed hands and was known as the Seneca Oil Company, was on the ground with orders to find oil. The man sent out was a small stockholder in the company, Edwin L. Drake, “Colonel” Drake as he was called. Drake had had no experience to fit him for his task. A man forty years of age, he had spent his life as a clerk, an express agent, and a railway conductor. His only qualifications were a dash of pioneer blood and a great persistency in undertakings which interested him. Whether Drake came to Titusville ordered to put down an artesian well or not is a mooted point. His latter-day admirers claim that the idea was entirely his own. It seems hardly credible that men as intelligent as Professor Silliman, Mr. Bissell, and others interested in the Pennsylvania Rock-Oil Company, should not have taken means of finding out how the familiar “Kier’s Rock-Oil” was obtained. Professor Silliman at least must have known of the quantities of oil which had been obtained in different states in drilling salt wells; indeed, in his report (see Appendix, Number 1) he speaks of “wells sunk for the purpose of accumulating the product.” In the “American Journal of Science” for 1840—of which he was one of the editors—is an account of a famous oil well struck near Burkesville, Kentucky, about 1830, when drilling for salt. It seems probable that the idea of seeking oil on the lands leased by the Petroleum Rock-Oil Company by drilling artesian wells had been long discussed by the gentlemen interested in the venture, and that Drake came to Titusville with instructions to put down a well. It is certain, at all events, that he was soon explaining to his superiors at home the difficulty of getting a driller, an engine-house and tools, and that he was employing the interval in trying to open new oil springs and make the old ones more profitable.
