Of the Excellent Qualities of Coffee. 639 



torn may be about a quarter of an inch above the 

 bottom of the boiler. 



The small quantity of water which it will be nec- 

 essary to put into the boiler, in order that the reservoir 

 for the coffee may be surrounded by steam, may be 

 introduced by means of a small opening on one side of 

 the boiler, situated above and near the upper part of its 

 handle. 



The spout through which the coffee is poured out 

 passes through the side of the boiler, and is fixed to it 

 by soldering. The cover of the boiler serves at the 

 same time as a cover for the reservoir and for the cylin- 

 drical strainer; and it is made double, in order more 

 effectually to confine the heat. 



The boiler is fixed below to a hoop, made of sheet 

 brass, which is pierced with many holes. This hoop, 

 which is one inch in width, and which is firmly fixed to 

 the boiler, serves as a foot to it when it is set down on 

 a table ; and it supports it in such a manner that the 

 bottom of the boiler is elevated to the height of half 

 an inch above the table. 



When the boiler is heated over a spirit lamp, or over 

 a small portable furnace in which charcoal is burned, as 

 the vapour from the fire will pass off through the holes 

 made in the sides of the hoop, the bottom of the hoop 

 will always remain quite clean, and the table-cloth will 

 not be in danger of being soiled when this coffee-pot 

 is set down on the table. 



As the hoop is in contact with the boiler, in which 

 there will always be some water, it will be so cooled by 

 this water as never to become hot enough to burn the 

 table-cloth. 



The bottom of the boiler may be cleaned occasion-
