During part of 1918 the writer investigated the Cannel Coal and other possible sources of oil, together with occurrences of free Petroleum in the Yorkshire, Durham, and Northumberland coalfields, and subsequently watched the Government borings for oil in Derbyshire. The main results of this work have already appeared in sundry Geological Survey Memoirs, but some general conclusions on the subject of Petroleum in England and the facts which suggested them are here put forward. The possible oil-bearing horizons are regarded as three in number: the Lower Carboniferous rocks of Derbyshire, the Coal Measures in various fields, and the Upper Jurassic or Lower Cretaceous strata of a part of the Sussex Weald. Before giving details, a few remarks on Petroleum in general are necessary.
