Fire-places and Kitchen Utensils. 221 



room, in which two of the principal boilers belonging 

 to the kitchen, and three large stewpans, are fixed. 



A and B are two steps, each 8 inches high, and the 

 upper (flat) surface of the mass of brick-work, in which 

 the boilers are set, and which is 45 inches wide, is just 

 30 inches above the level of the upper surface of the 

 step B. 



Neither the boilers nor stewpans are shown in this 

 plan, but their circular fire-places are represented, as 

 also their circular dishing iron grates, on which the fuel 

 is burned, and the horizontal canals by which the smoke 

 passes off into the chimney. 



The smoke divides under each of the two principal 

 boilers, and passes off in two canals situated on opposite 

 sides of the fire-place ; which canals, however, unite and 

 form one single canal at a small distance from the boiler. 

 In the fire-places of the stewpans the smoke does not 

 divide in this manner; but the fire-place is so constructed 

 that the flame makes one complete turn round the stew- 

 pan before it goes off into the horizontal canal leading 

 to the chimney. 



The opening by which the fuel is introduced into the 

 fire-place of each of the two large boilers is closed by a 

 conical stopper (constructed of fire-stone), represented 

 in the figure, immediately under which stopper the 

 (register) door of the ash-pit is situated. 



The ash-pit of each of the fire-places of the stewpans 

 is furnished with a register door. The passages into 

 these ash-pits are expressed in the figure by dotted lines. 

 The fuel (which is small pieces of wood about 5 inches 

 in length) is introduced into the fire-place from above 

 by removing the stewpan for a moment for that purpose. 



The chimney C, by which the smoke goes off, is
