Report of Judges on Steam Engines. 59 



petition should, of his own knowledge, know what is going on, and 

 immediately report to me anything that is unsatisfactory. The 

 power will be measured by the indicator and dynamometers. 



The latter are in plain sight of everybody ; the indices can be read 

 with an opera glass, and the power calculated in a moment. 



Mr. Bacon can, if he has leisure, furnish indicator diagrams to the 

 exhibitors interested. The cost of the j^ower will be ascertained by 

 measuring the feed water with a meter, open to the inspection of all. 



From the above, the number of pounds of water per horse-power 

 can be ascertained at any time. 



It is especially requested that all questions may be settled as soon 

 as they occur, and that all interested will satisfy themselves on every 

 point while the experiments are in progress, so that at the end, all 

 will be willing to testify to the accuracy of the results. 

 Very respectfully, 

 (Signed) CHAS. E. EMERY, 



General Superintendent Exhibition.
