242 On the Construction of Kitchen 



properly made and ready for setting, at less than 6d. 

 the pound, avoirdupois weight. The sheet iron would 

 cost them in the market, at the first hand, not more than 

 about $\d. per pound. The expense of setting the ovens 

 would not be considerable, especially as only one small 

 fire-place would be necessary. 



In some future publication, or in a subsequent part 

 of this Essay, I shall give a design of one of these 

 nests of ovens, with an exact estimate of the expense of 

 it: in the mean time I will endeavour to get one of 

 them put up for the public inspection at the Royal 

 Institution. 



I cannot close this chapter without once more calling 

 the attention of my reader to the necessity of furnish- 

 ing the canal tha't carries away the smoke into the 

 chimney with a damper. If this is not done in setting 

 the ovens I have just been describing, it will be quite 

 impossible to manage the heat properly. For the fire- 

 place of a small oven for the family of a cottager, a 

 common brick may be made to answer very well as a 

 damper ; and, indeed, a very good damper for any small 

 fire-place may be made with a brick or a tile or a 

 piece of stone. 



If, in addition to the introduction of a good damper, 

 care be taken to cause the smoke to descend about 

 12 or 15 inches just after it has quitted the oven (or the 

 boiler), and before it is permitted to rise up and go off 

 into the chimney, this will greatly contribute to the 

 economy of fuel. 



It is surely not necessary that I should again observe 

 how very essential it is in altering open chimney fire- 

 places whether they belong to kitchens, to the dwell- 

 ing-rooms of the opulent, or to cottages to build up
