AN ELEMENTARY AND PEACTICAL TREATISE ON 

 BEIDGE BUILDING. An enlarged and improved edition of 

 the Author s original work. By S. WHIPPLE, C. E., Inventor of 

 the Whipple Bridges, &c. Second Edition. 



The design has been to develop from Fundamental Principles a system easy 

 of comprehension, and such as to enable the attentive reader and student to 

 judge understandingly for himself, as to the relative merits of different plans 

 and combinations, and to adopt for use such as may be most suitable for the 

 cases he may have to deal with. 



It is hoped the work may prove an appropriate Text-Book upon the subject 

 treated of, for the Engineering Student, and a useful manual for the Practic 

 ing Engineer and Bridge Builder.
