The Work of the Royal Engineers in the European War,

1914-1919. Military Mining. Published by the Secretary, Institution of Royal Engineers, Chatham. (Chatham : W. and J. Mackay. 12s. 6d. net.)

The monographs on R.E. work in the late War, which are being issued by the Institution of Royal Engineers, fulfil the two great requisites of good history. They are a clear and concise narrative of what is past and a pregnant source of instruction for what may be to come. Thus, the first part of this volume describes the actual mining done on the Western Front, beginning with shallow defensive systems and cul- minating in the vast mines which blew the German advanced trenches into the air along the Messines front. The remainder deals with the elaborate arrangements for rescue work in mines and the technical lessons of the War.
