248 On the Construction of Kitchen 



work on that account. He thinks he could put up 

 another in two hours, and I am of the same opinion. 



I think it would be advisable, in order to facilitate 

 stowage and carriage of these small ovens, always to 

 manufacture them in nests of four, one within the other, 

 even w.hen they are designed to be sold, and to be put 

 up singly ; for it can be of no great importance whether 

 they be a quarter of an inch or half an inch wider or 

 narrower ; and it will often be a great convenience to 

 be able to pack them one within the other, especially 

 when they are to be sent to any considerable distance. 



If care be taken in making them to preserve their 

 forms and dimensions, and if the seams of the metal be 

 properly beaten down, the difference in the sizes of two 

 ovens that will fit one within the other need not be very 

 considerable. But I forget that I am writing for the 

 cleverest and most experienced workmen upon the face 

 of the earth, to whom the utility of these contrivances 

 is perfectly familiar, and who, without waiting for my 

 suggestions, will not fail to put them all in practice. 



Though there is nothing I am more anxious to avoid 

 than tiring my reader with useless repetitions, yet I can- 

 not help mentioning once more the great importance 

 of causing the smoke that heats one of the ovens I have 

 been describing to descend at least as low as the level 

 of the bottom of the oven, after it has passed round and 

 over it, before it is permitted to rise up freely and escape 

 by the chimney into the atmosphere. In setting the 

 oven, and forming the canal for carrying off the smoke 

 from the oven into the chimney, this may easily be 

 effected : and, if it be done, the oven will retain its heat 

 for a great length of time even after the fire is gone 

 out ; but, if it be not done, the fire must constantly be
