As Mr. Bourne's work has the great merit of avoiding unsound and imma- 

 ture views, it may safely be consulted by all who are really desirous of ac- 

 quiring trustworthy information on the subject of which it treats. During 

 the twenty-two years which have elapsed from the issue of the first edition, 

 the improvements introduced in the construction of the steam engine have 

 been both numerous and important, and of these Hr. Bourne has taken care 

 to point out the more prominent, and to furnish the reader with such infor- 

 mation as shall enable him readily to judge of their relative value. This edi- 

 tion has been thoroughly modernized, and made to accord with the opinions 

 and practice of the more successful engineers of tho present day. All that 

 the book professes to give is given with ability and evident care. The scien- 

 tific principles which are permanent axe admirably explained, and reference 

 is made to many of the more valuable of the recently introduced engines. To 

 express an opinion of the valuo and utility of such a work as The Artisan 

 Club's Treatise on tJie Steam Engine, which has passed through eight editions 

 already, would be superfluous ; but it may be safely stated that the work is 

 worthy the attentive study of all either engaged in the manufacture of steam 

 engines or interested in economizing the use of steam. — Mining Journal.
