His first venture seems to have been in 1873. In that year the oil-shipping firm of J. A. Bostwick and Company laid a short pipe in the Lower Field, as the oil country along the Allegheny River was called. Now J. A. Bostwick was one of the charter members of the South Improvement Company, and when Mr. Rockefeller enlarged his business in 1872 because of the power that enterprise gave him, he took Mr. Bostwick into the Standard. This alliance, like all the operations of that venture, was secret. The bitterness of the Oil Regions against the members of the South Improvement Company was so great for many months after the Oil War that Mr. Bostwick and Mr. Rockefeller seem to have concluded in 1873 that it would be a wise precautionary measure for them to lay a pipe-line upon which they could rely for a supply of oil in case the oil men attempted again to cut them off from crude, as they had succeeded in doing in 1872. Accordingly, a line was built and put in the charge of a man who has since become known as one of the “strong men” of the Standard Oil Company. This man, Daniel O’Day, was a young Irishman who had first appeared in the oil country in 1867, and had at once made so good a record for himself as transporting agent, that in 1869, when the oil-shipping firm of J. A. Bostwick needed a man to look after its shipments, he was employed. The record he made in the next two years was such that it reached the ear of Jay Gould himself, the president of the Erie, over which Mr. Bostwick was doing most of his shipping. Now the Erie at this time was making a hard fight to meet the growth of the Empire Transportation Company. So important did Jay Gould think this struggle that in 1871 he himself came to the Oil Regions to look after it. One of the first men summoned to his private car as it lay in Titusville was the young Irishman, O’Day. He came as he was, begrimed with the oil of the yards, but Mr. Gould was looking for men who could do things, and was big enough to see through the grime. When the interview was concluded, Daniel O’Day had convinced Jay Gould that he was the man to divert the oil traffic from the Pennsylvania to the Erie road, and he walked out with an order in his pocket which lifted him over the head of everybody on the road so far as that particular freight was concerned, for it gave him the right to seize cars wherever he found them. For weeks after this he practically lived on the road, turning from the Pennsylvania in this time a large volume of freight, and making it certain that it would have to look to its laurels as it never had before.
