134 ENGINE TESTS. 



Engine No. 32 is a cross-compound, having unjacketed hori- 

 zontal cylinders and unjacketed receiver. A surface condenser 

 is employed, and the air-pump is operated by direct connection 

 with the engine. The circulating-pump is a duplex steam 

 pump 9" x 10" x 12", and the steam it used is included in that 

 reported. The engine is furnished with steam from sectional 

 boilers, and it is presumed to be in a commercially dry condi- 

 tion. In the matter of leakage the engine was in excellent 

 condition throughout with the exception of the piston in the 

 high-pressure cylinder, which leaked a small amount. The 

 load consisted of a cotton-mill. The feed-water consumption 

 was determined by measuring the water discharged by the air- 

 pump.
