Exhibition of 1869 : 



Gentlemen. — In accordance with the " Regulations for the Trials 

 of the Steam Engines " entered for competition at the late exhibition, 

 I hereby report in full the facts demonstrated bv such trials, and 

 transmit also the logs, records and diagrams upon which the report 

 is founded. 



Mj regular duties connected with the closing of the exhibition, 

 prevented me from making the necessary computations until within 

 the past twelve days. 



This report has been written in such manner as to accomplish two 

 distinct purposes, and therefore includes 



First. Such record and statement of fact as it was my duty, as 

 superintendent, to record and report to the judges, in accordance 

 with article 4 of the Regulations of the Trial (Exhibit E) ; and, 



Secondly. The report includes calculations and explanatory remarks 

 which I have incorporated, by direction of the judges, as the facts 

 and the results of their consideration of the same, become known 

 from time to time. 



Four engines were tested, viz. : An engine manufactured under the 

 Corliss patent, by Mr. Wm. A. Harris, of Providence, Rhode Island ; 

 an engine of the Babcock and Wilcox patent, manufactured by the 

 Hope Iron Works, also of Providence ; an engine of the Rider pat- 

 ent, manufactured by the Helamater Iron Works in New York city ; 

 and an engine of the Loomis patent, manufactured by the Fishkill 

 Landing Machine Company, of Fishkill, Xew York.
