"A work of this extremely valuable character deserves to be made widely known amongst colliery managers and mining engineers at home and abroad."--_Coal and Iron._ "This book is, in a manner, unique. The literature of mining accidents is fairly extensive, but it consists largely of departmental Blue Books."--_Sheffield Daily Telegraph._ "A concise and lucid description of the principal methods pursued, especially in fiery mines, and of the various appliances employed, such as respiratory and rescue apparatus, dams, etc."--_Staffs Advertiser._ "The prevention of spontaneous combustion in collieries and the extinction of underground fires are duties that fall heavily on many colliery managers. They should, therefore, welcome this translation of Mr. Lamprecht's German treatise."--_Ironmonger._ "The book under notice supplies the needed full description, drawings, and mode of using these new appliances in actual fires, and should be studied by every colliery manager, seeing that even our best managed collieries have not been free from fires, more or less disastrous to life and property.--_Colliery Manager._ * * * * * =THE PREVENTION OF SMOKE.= Combined with the Economical Combustion of Fuel.
