I90 COMPARATIVE RESULTS IN STEAM AND COAL CONSUMPTION. 



accuracy of the tests, I submit the following as one taking an active part in the 

 engine and engine turbine tests. 



The coal and water consumption tests were made under average working 

 conditions, the coal being run of mine bituminous coal as obtained in New York 

 Harbor. The firing was done by the yacht's firemen without being coached or 

 interfered with in any particular and as the boilers were steaming easily, they, if 

 anything, neglected the fires. Two fires were cleaned every watch. 



In making the water tests, one feed pump delivered the condensed water from 

 the hot well into two tanks; and the drain from these tanks went into the water 

 bottom. These tanks were carefully calibrated and were sloped top and bottom, 

 so as to drain quickly and absolutely, and so that no air could be trapped. 



The results, as given, can be duplicated in actual service and probably bettered. 



Mr. Crane is to be congratulated on the success of his venture, and on the fact 

 that the tests were made under strictly service conditions. 



The President vacated the chair and Vice President McFarland took his place 

 as chairman. 



The Chairman : — The paper "Some Suggestions for Reducing the Loss by Fire
