Of the Excellent Qualities of Coffee. 645 



of the height which is necessary in order that it may 

 contain two coffee-cups full of water. 



Each of these strainers has its separate rammer to 

 ram down the ground coffee placed in it, but one com- 

 mon handle serves for them all. This handle is screwed 

 into the middle of a circular plate, which forms the 

 principal part of the rammer. 



The circular plate which belongs to each of these 

 strainers remains in it when the coffee-pot is not in 

 use, and the handle remains attached to the circular 

 plate belonging to the smaller strainer. 



When only two cups of coffee are wanted, the two 

 largest strainers being taken away, the smaller strainer 

 is used alone. 



If either three or four cups are wanted, the smallest 

 and the largest strainers are taken away, and the other 

 strainer is used. 



When five or six cups are wanted, the largest strainer 

 is used, and the other two are taken away. 



If seven, eight, nine, or ten cups are wanted, six cups 

 are first made with the largest strainer; when, that 

 strainer being removed, the remaining number of cups 

 are made with the strainer next in size. 



By making use of the three strainers one after the 

 other, eleven or twelve cups of coffee may be made in 

 this coffee-pot ; and, as the heat always remains the same 

 during the whole of the time employed in these oper- 

 ations, the coffee is just as good as if the whole of it 

 were made at once. 



By adding two additional strainers to the coffee-pot 

 represented by the Fig. i, one of them of a proper size 

 for making one cup of coffee, and the other of a proper 

 size for making two cups, this coffee-pot may be used
