well covered with double covers to prevent the loss of 

 the heat, that the processes of boiling and stewing can 

 be carried on with very small portable furnaces and 

 with heaters ; but with these utensils, which are so well 

 calculated to confine the heat, it is almost incredible 

 how small a supply of heat will be sufficient, when the 

 contents of the vessel have previously been made boil- 

 ing-hot, to keep up that temperature, and carry on any 

 of the common processes of cookery. 



In the following figure (Fig. 55) A represents a verti- 

 cal section of a stewpan, 1 1 inches wide at its brim and 



Fig- 55- 



6 inches deep, suspended in its cylinder and placed 

 upon a portable furnace, B, which is 7 inches in diam- 

 eter at its opening above, 1 1 inches in diameter below, 

 and 9 inches high. A small saucepan, C, for melting 

 butter, is placed on the cover of the stewpan, and is 

 heated by the steam from the stewpan.
