liable to boil over. The kettle so filled will contain 4 

 pints of water ; and, if it be heated over one of the small 

 portable furnaces described in the foregoing chapter, it 

 may be made to boil in about 10 minutes, with 6^ oz. 

 of dry wood, which, at the price at which wood is com- 

 monly sold in London, would cost f of a farthing.* 



The tea-kettle represented by the following figure is 

 rather more complicated, but still its form is more sim- 

 ple, and more advantageous in several respects than 

 those which are in common use, and it is well adapted 

 for the fire-places we have recommended. It is drawn 

 to a scale of 6 inches to the inch. 



Fig. 68. 



This kettle has two handles, each of which is sup- 

 ported on the outside, or near the circumference of the 

 kettle, by a small vertical tube, f of an inch in diameter 

 and if inches in height. That on the left hand is 

 open, and forms a part of the spout ; but that on the 

 right hand is closed at both ends. The bottom of this 

 kettle, also the bottoms of those represented in the two 

 following figures, like that of the last (Fig. 67), is not 

 flat, but is raised up about half an inch above the level 

 of the lower part of the cylindrical sides of the kettle. 



* One pint of water only being put into this tea-kettle, over a very small wood 

 fire, made in the portable furnace represented in the foregoing Fig. 63 (see 

 page 414), it was heated and made to boil in two minutes and a half.
