Rh Mr. Merrill discovered a process by which a deodorised lubricating oil could be made. He had both the apparatus for producing the oil and the oil itself patented. The oil was so favourably received that the market sale by the Downer works was several hundred per cent. greater in a single year than the firm had ever sold before.

The oil field had been extended from the valley of Oil Creek and its tributaries down the Allegheny River for fifty miles and probably covered 2,000 square miles. The early theory that oil followed the streams had been exploded, and wells were now drilled on the hills. It was known, too, that if oil was found in the first sand struck in the drilling, it might be found still lower in a second or third sand. The Drake well had struck oil at 69% feet, but wells were now drilled as deep as 1,600 feet. The extension of the field, the discovery that oil was under the hills as well as under streams, and to be found in various sands, had cost enormously. It had been done by "wild-catting," as putting down experimental wells was called, by following superstitions in locating wells, such as the witch-hazel stick, or the spiritualistic medium, quite as much as by studying the position of wells in existence and calculating how oil belts probably ran. As the cost of a well was from $3,000 to $8,000, according to its location, and as 4,374 of the 5,560 wells drilled in the first ten years of the business (1859 to 1869) were "dry-holes," or were abandoned as unprofitable, something of the daring it took to operate on small means, as most producers did in the beginning, is evident. But they loved the game, and every man of them would; stake his last dollar on the chance of striking oil.

With the extension of the field rapid strides had been made in tools, in rigs, in all of the various essentials of drilling a well. They had learned to use torpedoes to open up hard rocks,
