io Of the Management of Fire 



amounting to no less than 62^ Ibs.). And this shows 

 how very considerable the waste of fuel really is, in the 

 manner in which it is commonly employed for culinary 

 purposes, and how important the savings are which may 

 be made by introducing a more advantageous arrange- 

 ment for the management of fire. But great as these 

 savings may appear to be, as shown by the results of 

 the foregoing experiments, yet they are in fact still 

 more considerable, as will be abundantly proved in the 

 sequel. In the Experiment No. 2, in which the boiler 

 was put over an open fire, great care was taken to 

 place the fuel in the most advantageous manner; but 

 in general little attention is paid to that circumstance, 

 and the waste of fuel is greatly increased by such negli- 

 gence. But in closed fire-places, upon a good con- 

 struction, as the proper place for the fuel cannot be 

 mistaken, and as it is fixed and bounded on all sides 

 by a wall, the ignorance or inattention of those who 

 take care of the fire can never be productive of any 

 great waste of fuel ; and this is an advantage of no 

 small importance attending these fire-places. 



Experiment No. 3. A large copper sauce-pan or 

 casserole, \\\ inches in diameter above, lof in diameter 

 below, and 3! inches deep, containing 4 measures of 

 water weighing y^jj- Ibs., and at the temperature of 58 F., 

 being placed in its closed fire-place, and a fire being 

 made under it with small pieces of dry beech-wood cut 

 in lengths of about 4 inches, the water was made to 

 boil, and was continued boiling two hours. 



The result of the experiment was as follows :
