Rh apparatus was very simple—a cast-iron still, usually surrounded by brick-work, a copper worm, and two tin- or zinc-lined tanks. The still was filled with crude oil, which was subjected to a high enough heat to vapourise it. The vapour passed through a cast-iron goose-neck fitted to the top of the still into the copper worm, which was immersed in water. Here the vapour was condensed and passed into the zinc-lined tank. This product, called a distillate, was treated with chemicals, washed with water, and run off into the tin-lined tank, where it was allowed to settle. Anybody who could get the apparatus could "make oil," and many men did—badly, of course, to begin with, and with an alarming proportion of waste and explosions and fires, but with experience they learned, and some of the great refineries of the country grew out of these rude beginnings.

Luckily not all the men who undertook the manufacturing of petroleum in these first days were inexperienced. The chemists to whom are due chiefly the processes now used—Atwood, Gessner, and Merrill—had for years been busy making oils from coal. They knew something of petroleum, and when it came in quantities began at once to adapt their processes to it. Merrill at the time was connected with Samuel Downer, of Boston, in manufacturing oil from Trinidad pitch and from coal bought in Newfoundland. The year oil was discovered Mr. Downer distilled 7,500 tons of this coal, clearing on it at least $100,000. As soon as petroleum appeared he and Mr. Merrill saw that here was a product which was bound to displace their coal, and with courage and promptness they prepared to adapt their works. In order to be near the supply they came to Corry, fourteen miles from the Drake weil, and in 1862 put up a refinery which cost $250,000. Here were refined thousands of barrels of oil, most of which was sent to New York for export. To the Boston works the firm sent crude, which was manufactured for the home trade and
