SECTION OF TRANSPORTATION AND ENGINEERING. Ill 



Class FJ.— Maps showing extensions of railway system in the United 

 States. 



Class VII. — Methods of transportation in other countries. 



As this is the first attempt in the history of expositions to tell the 

 story of the development, step by step, of our great systems of transpor- 

 tation by series of models, drawings, and relics, the interest manifested 

 in the subject by those to whom I applied for assistance was most grat- 

 ifying. Had I not received their hearty co-operation little could have 

 been accomplished in the brief time allotted to the task. 



The cordial thanks of the Museum are hereby extended to President 

 Spencer and Col. James Eandolph, of the Baltimore and Ohio Eail- 

 road; to Joseph T. Eichards, assistant chief engineer, and W. J. 

 Latta, general agent, Pennsylvania Eailroad Company, Philadelphia; 

 to Messrs. Burnham, Parry, Williams & Co., proprietors of the Bald- 

 win Locomotive Works ; Harper Bros., New York City 5 Francis B. 

 Stevens, civil engineer, Hoboken, New Jersey ; and Dr. Henry Mor- 

 ton, president of Stevens Institute of Technology, Hoboken, New 

 Jersey, for their assistance. 



While the withdrawal of objects from the Museum collection for this 

 exposition will impair the educational value of the series to the vis- 

 itors of the Museum during the first four months of the next fiscal year, 

 it is hoped that the exhibit made at Cincinnati will stimulate the inter- 

 est of the people of that region in the subject that has added so largely 

 to their prosperity, so that ultimately the collection will be strength- 

 ened by additions from that quarter. 



It is believed that when the series now at Cincinnati is returned, and 

 the objects, properly classified, become permanently installed, the Mu- 

 seum will possess a collection of very great historical value.
