78 METHODS OF MAKING COFFEE. 



great variety of inventions, one of the most noted being Count 

 Rumford's percolator, in which the ground coffee is compressed 

 between two metallic diaphragms, so that the boiling water 

 shall percolate slowly through the mass. TKere is also the 

 Fountain coffee-maker, in which a body of steam, passing up- 

 wards through the body of ground coffee, carries over the infu- 

 sion, which collects in a chamber. 



Another apparatus is the pneumatic filter, by which the per- 

 colation of the coffee is expedited and rendered more complete. 



Having thus shown the various methods and principles by 

 which coffee is prepared in different countries, it may not be in- 

 appropriate to add that Yankee ingenuity has not been idle in 

 trying to solve the problem as to how this beverage can best be 

 made. There have been about one hundred and seventy-five 

 patents granted by the United States Patent Office for coffee- 

 pots alone, embracing every possible contrivance by which the 

 bean can be prepared as a beverage ; and while so many are 

 seeking this " arcanum," we find some of the devices both curious 

 and ingenious. There is a patent granted for placing a furnace 

 in the coffee-pot; another with curious strainers and attach- 

 ments to receive the grounds; again another with arrange- 

 ments to prevent lateral tipping when tilting the coffee-pot; 

 patents for strainers connected with springs attached to the noz- 

 zle ; others with hot-water jackets, and some with condensers 

 in the lids to catch the aroma ; some to hold both coffee and 

 tea, to be made at the same time in different compartments ; 

 and so the list could be continued at length, showing the 

 claims of the many inventive geniuses w^ho have given their 

 attention to this subject. 



We will conclude by referring to one of the latest patents, 

 which, if judged from its success and the praises it has received 

 from those who have used it, is destined to become the general 

 economizer and only true method of preparing coffee. Its con-
