During the prosecution of the work Mr. Doolittle died, and, in 1861, Dr. Streator sold the unfinished contracts to Mr. James McHenry, of London, England, by whom they were completed, Dr. Streator acting as superintendent of construction for about a year after the transfer of contract. [Illustration: Yours Truly, W. S. Streator] In 1862, he projected the Oil Creek Railroad, from Corry to Petroleum Center, the heart of the Pennsylvania oil regions, a line thirty-seven miles long. The line was built with extraordinary rapidity, and achieved a success unparalleled in railway history. No sooner had the rails reached a point within striking distance of Oil Creek than its cars were crowded with passengers flocking to the "oildorado," and for many months, during the height of the oil fever, the excited crowds struggled at the stations for the privilege of a standing place on the car platforms after the seats and aisles were filled. The resources of the road were inadequate to meet the great demand on it for the transportation of passengers and oil, and although Dr. Streator worked energetically to keep pace with the demand upon the road, the development of the oil regions, consequent upon the construction of the line, for some time outstripped him. The profits of the line were enormous in proportion to the outlay, but the amount of wealth it created in the oil regions was still more extraordinary. Dr. Streator managed the road until 1866, when he sold out his interest to Dean Richmond and others interested in the New York Central Railroad. In order to connect the Oil Creek Railroad with the line of its purchasers an extension northward, styled the Cross-Cut Railroad, was built from Corry to Brocton, on the Buffalo and Erie Railroad, a distance of forty-two miles, by Dr. Streator, for the New York Central Railroad Company. This was the last of Dr. Streator's railroad building undertakings. Since the close of his railroad business Dr. Streator has organized a company, mainly composed of citizens of Cleveland, for the working of coal lands purchased in La Salle, on the Vermillion river, Illinois. The purchase contains three thousand acres on which is a five and one-half feet splint-vein of coal resembling in general characteristics the Massillon coal of Ohio. Thirteen miles of railroad have been built to connect the mines with the Illinois Central Railroad, and during the year that the road has been opened the average product of the mines has been two hundred and fifty tons per day, with demands for more, that cannot be met owing to a deficiency of rolling stock. By the close of 1869, it is expected the product will reach a thousand tons daily. Another railroad is to be built to connect with the Chicago, Burlington & Quincy Railroad.
