 December. — Temperature and Coal Record. 



Soon after the test began, the minimum thermometer in the hot-water 

 house was broken, and owing to delay in replacing, we are not able to give 

 the minimum record for December for that house. 



From the first, a difference was noticed in favor of the hot-water heater. 

 The temperature was generally one to three degrees higher, and consider- 

 ably less coal was consumed. 



During December the amount used in the hot-water heater averaged 75 

 pounds per day, while the steam heater needed 93.2 lbs., a difference of 

 about 25% in favor of hot-w\ater heating. A difference of 2.5° also in tem- 

 perature, should not be overlooked. The draft regulator was not completed 

 \intil the middle of January.
