nine inches in depth (according to the dimensions 

 of the joists) between every two joists, along the 

 entire length of the building. 



About ten feet length of one end of the lower 

 apartment should now be partitioned off from the 

 rest, the sides of the chamber thus formed being as 

 near as possible air-tight. It must, however, have 

 no ceiling other than the floor above, so that the 

 spaces just described between the mat-covered 

 floor of the upper storey and the ceiling of the rest 

 of the lower apartment may all open into it. 

 In an opening in the wall of this chamber, a pair 

 of large revolving fans must now be adjusted, 

 exactly like the fans of a winnowing machine, but 

 on a larger scale. These fans are connected by 

 means of belts with the water-wheel, and when 

 made to revolve rapidly draw out a continuous 

 current of air from the inside, and as there is only 

 one source whence this air can be derived, it is of 

 necessity sucked out of the spaces under the floor 

 of the upper storey on which the parchment coffee 

 is heaped, and consequently through the coffee itself. 



By this process the parchment coffee in store, 

 once partially dried, can be kept thoroughly well- 

 aired and free from fermentation, without any 

 turning over. But for coffee that is still wet, 

 something more is necessary, and this brings us to 

 the hot-air apparatus. At the furthest end from
