Boiler No. 32 embraces a 

 plant of two horizontal tubu- 

 lar boilers, arranged in the 

 manner shown in the follow- 

 ing cuts. The boilers are 

 set over a single furnace, 

 and the upper surfaces of the 

 shells are exposed to the 

 heat of the escaping gases 

 on their way from the front 

 smoke arch to the flue, 

 thereby furnishing a small 

 amount of steam heating sur- 

 face. The boiler had been 

 in service for several years, 

 but the inside surfaces were 

 free from scale, and both boiler and settings were in every 

 way in good condition. This boiler was the end boiler of a 

 large plant, and the boiler next to it was in operation during 

 the progress of the tests.
