 gineer.

 in some superior." — Leader. 



" Marked by the tact, care, and usefulness which characterise 

 all Mr. Timbs's books."— Notes and Queries. 



" Mr. Timbs possesses the rare faculty of clear and accurate 

 condensation. He is never obscure, nor does he apparently omit 

 any thing essential. We cordially recommend his volume to our 

 readers." — Lancet. 



"This book is eminently discursive, and exceedingly chatty 

 and interesting." — Critic. 



"This new volume surpasses any of its predecessors: the in- 

 formation is so varied and instructive, that the book should be. 

 road by all." — Mining Journal. 



'• This is certainly one of the most ivrious and interesting of 

 Mr. Timbs's books; there is less of mere extract and more oJ 

 judicious and skilful compilation than in some of its predecessors. 

 'We recommend the work to the leisure moments ot p ur Pas- 

 sional and other readers, as one sure to repay tenfold both the 

 cost and trouble." — Builder.
