the region, written that year, says of the borings for salt-water: “They have sunk two wells more than four-hundred feet; one of them affords a strong and pure water, but not in great quantity; the other discharges such vast quantities of petroleum, or as it is vulgarly called “Seneca Oil,” and besides is subject to such tremendous explosions of gas * * * that they make little or no salt. Nevertheless, the petroleum affords considerable profit and is beginning to be in demand for workshops and manufactories. It affords a clear, brisk light, when burned in this way, and will be a valuable article for lighting the street-lamps in the future cities of Ohio.” The last sentence bears the force of a prophecy. Writing about the year 1832 the same observant author directs attention to another peculiar feature: “Since the first settlement of the regions west of the Appalachian range the hunters and pioneers have been acquainted with this oil. Rising in a hidden and mysterious manner from the bowels of the earth, it soon arrested their attention and acquired great value in the eyes of the simple sons of the forest. * * * From its success in rheumatism, burns, coughs, sprains etc., it was justly entitled to its celebrity. * * * It is also well adapted to _prevent friction in machinery_, for, being free of gluten, so common to animal and vegetable oils, it preserves the parts to which it is applied for a long time in free motion; where a heavy vertical shaft runs in a socket it is preferable to all or any other articles. This oil rises in greater or less abundance in most of the salt-wells and, collecting where it rises, is removed from time to time with a ladle.” Is it not strange that, with the sources of supply thus pointed out in different counties and states and the useful applications of petroleum fairly understood, its real value should have remained unappreciated and unrecognized for more than thirty years and be at last determined through experiments upon the distillation of bituminous shales and coals? Wells sunk hundreds of feet for salt water produced oil in abundance, yet it occurred to no one that, if bored expressly for petroleum, it could be found in paying quantity! Hamilton McClintock, owner of the “oil-spring” famed in history and romance, when somebody ventured to suggest that he should _dig_ into the rock a short distance, instead of skimming the petroleum with a flannel-cloth, retorted hotly: “I’m no blanked fool to dig a hole for the oil to get away through the bottom!” [Illustration: KENTUCKY’S FIRST OIL-WELL.]
