inch wide, which projects outwards from its upper 

 (larger) end. A rim of equal width, projecting inwards 

 at its lower extremity, supports a circular grate, on 

 which the fuel burns. The cylinder, which is about 

 two inches less in diameter than the larger cone at its 

 base, and which rests upon the surface of that cone, 

 serves to support the boiler or saucepan. This cyl- 

 inder is firmly fixed to the cone on which it rests by 

 means of rivets, two of which are represented in the 

 figure. The upper end of this open cylinder is strength- 

 ened, and its circular form preserved, by means of a 

 strong iron wire, over which the sheet iron is turned. 

 There is a short horizontal tube (A) on one side of the 

 cylinder, which is destined for receiving a longer tube 

 which carries off the smoke. The air necessary for the 

 combustion of the fuel is admitted through a circular 

 hole (B), about i^ inches in diameter, in the side of 

 the larger cone near its bottom, and below the joining 

 of the cone with the cylinder which rests on it. This 

 hole for the admission of air should be furnished with 

 a register, by means of which the fire may be regulated. 

 The handle of the stewpan is omitted in this plate, as 

 is also that of the fire-place. This figure is drawn to 

 a scale of 8 inches to the inch. 



The following figure (which is drawn to a scale of 12 

 inches to the inch) is a perspective view of one of these 

 portable furnaces without its stewpan. 



A part of the handle of this furnace is seen on the 

 left hand ; and the short tube is seen on the right hand, 

 that receives another tube (a part of which only is 

 shown) by which the smoke passes off. 



The stewpan represented in the Fig. 60 is supposed 

 to be made of copper, and to be constructed on the
