March. — Temperature and Coal Record. 



"This month's record is much like those of the preceding months. The 

 lower temperature required the burning of considerably more coal, but the 

 relative temperature of the two houses and the amount of coal is but little 

 changed. 



The following shows the average temperature and amount of coal con- 

 sumed in each of the houses during the period covered by the test:

This shows for nearly four months an average of 1.85" in favor of hot 

 water, and a coal consumption in the steam heater 21.5 % greater.
