Fire-places and Kitchen Utensils. 365 



The foregoing figure represents a horizontal section 

 of the brick-work in which these boilers are to be set, 

 taken at the level of the tops of the flues. 



A, B, is the side of the room ; and A, C, D, E, the 

 mass of brick-work which is placed against it ; F, G, 

 and H are the three parallel flues ; and I is the canal 

 that carries off the smoke from the second boiler to 

 the chimney; K is the opening into the fire-place 

 by which the fuel is introduced ; and L is a passage, 

 closed up with a tile or with loose bricks, which is 

 occasionally opened to clean the flues, G and H. The 

 damper in the canal, I, may be placed near the left- 

 hand side of the second boiler. The situations of the 

 boilers are indicated by dotted lines. 



As it is not necessary that I should repeat in this 

 place the directions which have already been so amply 

 explained concerning the proper method of proceeding 

 in setting boilers, I shall not enlarge farther on that 

 subject, but shall proceed to give an account of a 

 very essential part, not yet described, of the apparatus 

 necessary for cooking with steam in the simple way I 

 have here recommended : the part I mean is the steam- 

 rim of the boiler. 



Description of a Steam-rim for a Boiler, by Means of 

 which its Cover may easily be made steam-tight. 



To give a more complete idea of this contrivance, 

 I have, in the following figure, represented a vertical 

 section of a small part of one side of a boiler and its 

 steam-rim with its (wooden) cover in its place, both of 

 one half size. 



A, B, is a section of part of the flat wooden cover; 

 the crooked line, C, D, is a section of the steam-rim,
