Editor's Preface. vii 



The careful attention of the reader is asked to the teachings 

 of Prof. Du BREUIL, from whom we may learn much that is 

 useful, though we may not be inclined to adopt literally all 

 of his suggestions. The American workman is not a machine, 

 blindly to follow in the nits that have been worn for him by 

 his predecessors, nor hastily to adopt suggestions : it is our 

 boast that we have intelligent labor, which ever becomes 

 skilled labor the thinking laborer has greatly the advantage 

 over the mere routinist, and though he may not be a good 

 subject, the American workman makes a- capital sovereign, who 

 always prefers to direct his own efforts, and will often im- 

 prove upon the teachings of his professor. 



To distinguish the Editorial matter from the text it is set 

 in smaller type, and within brackets.
