Although Mr. Kier seems to have done a good business in rock-oil, neither he nor any one else up to this point had thought it worth while to seek petroleum for its own sake. They had all simply sought to utilise what rose before their eyes on springs and streams or came to them mixed with the salt-water for which they drilled. In 1854, however, a man was found who took rock-oil more seriously. This man was George H. Bissell, a graduate of Dartmouth College, who, worn out by an experience of ten years in the South as a journalist and teacher, had come North for a change. At his old college the latest curiosity of the laboratory was shown him—the bottle of rock-oil—and the professor contended that it was as good, or better, than coal for making illuminating oil. Bissell inquired into its origin, and was told that it came from oil springs located in Northwestern Pennsylvania on the farm of a lumber firm, Brewer, Watson and Company. These springs had long yielded a supply of oil which was regularly collected and sold for medicine, and was used locally by mill-owners for lighting and lubricating purposes. Bissell seems to have been impressed with the commercial possibilities of the oil, for he at once organised a company, the Pennsylvania Rock-Oil Company, the first in the United States, and leased the lands on which these oil springs were located. He then sent a quantity of the oil to Professor Silliman of Yale College, and paid him for analysing it. The professor’s report was published and received general attention. From the rock-oil might be made as good an illuminant as any the world knew. It also yielded gas, paraffine, lubricating oil. “In short,” declared Professor Silliman, “your company have in their possession a raw material from which, by simple and not expensive process, they may manufacture very valuable products. It is worthy of note that my experiments prove that nearly the whole of the raw product may be manufactured without waste, and this solely by a well-directed process which is in practice in one of the most simple of all chemical processes.”[1]
