Skinner, editor Mining Manual and Mining Year Book. 214 pp. 8^ in. x 5| in. London: 11-12, Clements-lane, E.C. 4. Price, 2s. 6d. net. The eighth annual issue of this reference work, which is now the only annual book published dealing with the oil industry, contains full particulars of 545 oil and petroleum companies (British and foreign) operating in all parts of the world, the particulars of which have been officially verified. In addition, alpha- betical lists of names and addresses of 1,282 directors, 253 secretaries, and 135 consulting engineers, managers, agents, etc., are given. The particulars of each company include the directors and other officials, date established, location of property, purchase con- sideration, royalties payable, number of wells sunk, oil production, and description of work in progress, capital, if offered to the public, calls, dividends, and financial position as disclosed by accounts, also latest price of shares. A table showing the monthly produc- tion of the principal English oil companies for the year is also given, together with the world’s production of petroleum from 1857 from the principal contributing companies.
