Press Opinions. 



"This book is. in a manner, unique. The literature of mining accidents is fairly extensive, 

 but it consists largely of departmental Blue Books." Sheffield Dail\' 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 .Man.i^er. 



" Herr Lamprecht has collated such a vast mass of useful information that it can never 

 fail to be of utility to the mine manager, even though, on occasion, it should only be in the 

 direction of inducing measures to prevent a recurrence of similar calamities." Newcastle 

 Chronicle. 



" It is the only existing work which deals exclusively with the branch of the miner's art 

 indicated by its title. . . . The author presents his subject in a clear, practical manner, and 

 seems to leave nothing unexplained that is necessary to make the book a thoroughly useful 

 and easily assimilated authority, on which pit managers and others may rely for guidance 

 in case of catastrophe." \l'i.^an Examiner.
