assist, and not impede, a regular circulation of air to 

 either. A represents a building 40 feet by 20 wide, 

 containing two floors of the same dimensions. The lower 

 one is used for weighing and stowing the hops in harvest 

 time, and is sufficiently open on one side to admit 

 of the waggons or carts bringing in the hops, additional 

 light being given by means of regular windows. The upper 

 floor is used for receiving the hops from the kiln, spreading 

 and cooling them, and packing them for market, B, c, and 

 D are ground plans of three circular kilns, in which the fires 

 are made and the hops dried. The figs. 1, 2, 3 are open- 

 ings for the admission of persons and of air to the kilns, and 

 figs. 4, 5, 6, 7 are outer doors opening into the passage from 

 the outside, so placed as while giving admission to air, 

 they cause it to circulate in the interior passage before 

 passing into the kiln, and thus prevent irregular currents 

 acting upon the fires, which always are detrimental to 

 the hops on the drying floors above. These doors may 

 be closed or open, according to the force of the wind and 

 direction from which it comes. An oast-house of the plan 

 and dimensions here given will dry about 1200 bushels 

 per day 200 bushels being got off of each kiln twice 

 daily; and as the kilns are independent of each other, 

 either or all of them may be worked, as may be required.
