This, with the BOVEY TRACEY BITUMINOUS DEPOSIT. 211 exception of the bitumen of Ritchie County, Virginia, which gives 170 gallons, and the Breckenridge coal of America, which yields 130 gallons, is the largest quantity of oil yielded by bituminous substances. This mineral has been very largely used for the production of paraffin and its products. It was used under a patent by Mr. Young in the year 50, and Young''s paraffin oil, which gave the start to the use of mineral oil lamps in this country, was made from it.

The manufacture of oil from this mineral led to a vast amount of litigation; part of this lay between Mr. Young and the distillers of oil from cannel in England and the producers of petroleum in America, which happily ended in unrestricted manufacture, and part with the owners of the ground. The great question was whether the mineral was coal or not coal. The bulk of the evidence went to prove that it was not coal, but a bituminous shale or clay.

A deposit of bituminous coal occurs, and has at various times been worked, near Bovey Tracey, in Devonshire. The deposit occurs in clays and sands that overlie the Greensand, and is of Tertiary age.
