2 1 4 On ttie Construction of Kitchen 



brick-work, circulates in canals divided into several 

 branches under an iron plate that forms the bottom of 

 an oven, which is situated under the hearth of the open 

 chimney fire-place. From under the bottom of this oven 

 this smoke goes off obliquely, and, entering the bottom 

 of the vertical canal/, goes off into the chimney. The 

 principal use of this oven is to dry the wood that is used 

 as fuel in the kitchen. The large boiler Q, that is heated 

 by this smoke, is designed for warming water for the 

 use of the kitchen, and for various other purposes for 

 which hot water is occasionally used in the hospital. 



The boiler P is principally used in preparing food for 

 the children in the hospital. 



The smoke from the fire which heats the boiler R, 

 passing off in a canal which leads to the boiler S, there 

 separates, and passing round the sides of the boiler S, 

 and under a small part of its bottom, unites again, and 

 passes off into the chimney by the vertical canal r. 

 The heat in this smoke, though it is sufficient to warm 

 the water in the boiler S, is not sufficient to make it 

 boil. In order that the contents of this boiler may 

 occasionally be made boiling-hot, the boiler has a small 

 fire-place of its own, situated immediately under the 

 middle of its bottom ; and when the water in the boiler 

 has been previously made warm by the smoke from the 

 boiler R, a very small fire made under it, in its own sepa- 

 rate fire-place, will make it boil. The smoke from this fire- 

 place goes off by its own separate canal into the vertical 

 canal s t so that it does not interfere at all with the smoke 

 from the fire-place of the boiler R ; and, in consequence 

 of this arrangement, the heating of the boiler S, by the 

 smoke from this neighbouring fire-place and by its own 

 fire, may be going on at the same time.
