"This series of books, edited by Wm. E. Worthen, form a complete conrse 

 of instruction for the mechanic, architect, and engineer, and are not mere 

 copies for tbe draughtsman, but also contain correct and intelligible means of 

 determining the amount and direction of strains to which different parts of a 

 machine or structure may be subjected, and the safe and permanent resistance 

 of these strains, with practical applications of the same. They also afford 

 suggestions and aids to the mechanic in the execution of new designs. Under 

 the head of Architectural Drawing, the general characteristics of various 

 styles have been treated of and illustrated, with remarks on proportion and 

 color. In the department of Topographical Drawing, selections have been 

 made from the best authorities, viz. : "Williams, Gillespie, Smith and Frowe. 

 In practical drawing, the author brings the experience of a series of years in 

 each department treated of."— Detroit Advertiser.
