Durinff the winter the stove fire has 

 scarcely ever been out; I requested Mr. 

 White to take particular notice of the 

 temperature during the months of De- 

 cember and January, at stated periods, 

 both in and out of doors, and I obtained 

 from him the following observations and 

 particulars regarding its management. 



About 4 p. M. the embers in the stove 

 were stirred after being shut up all day ; 

 a little coke was then put in and air freely 

 admitted ; after being fairly kindled and burning briskly, a little 

 more coke was applied and then regulated for the evening ; 

 about 9 p. M. the burning coke was again stirred, the stoves 

 then filled and ventilated according to the appearance of the 

 night. At seven the following morning the temperature was 

 observed both in and out of doors, and the following table will 

 show the result of the observations kept during that period. 



With the exception of the 26th of Dec. three of the flue covers 

 were always kept up, but on that night all were down, and the 

 thermometer in consequence fell below 60°. After marking the 

 temperature, a little more coke was given and the stove shut up 

 close for the day. The thermometer in the evenings, when the 

 fire was made up, generally ranged from 65° to 68°.
