the wall at the height of 1 1 feet, across which are 

 placed strips two inches square, and nine inches apart. 

 Over these is spread a strong cloth made of horse hair. 

 Figure 100 shows a plan of the drying floor, capacity 

 35 to 5 bushels. The wall is carried about two 

 feet higher, and plates are placed upon it, and 

 terminated by a sharp wooden roof. At the top of the 

 roof should* be a hole about five feet in diameter, 

 around which is placed a circular plate somewhat 

 larger on the outside than the hole itself. Upon this 

 plate is placed a cowl, to keep out the rain and let off 

 the vapor. It turns with the wind. On the ground 

 floor is the furnace. A door connects the kiln with the 

 storage room below and the chambers above, for 

 receiving, cooling and packing the hops. The furnace 

 is built so that the heat rises from the center. A wall 

 two feet high is raised, upon which is placed an iron 

 grate, three feet wide and four feet long. The wall is 

 carried a few bricks higher, solid, after which it is 

 raised in open work two feet higher, the bricks lapping 

 over each other about two inches. The two sides and 

 back end being built, the top is covered by flat tile, 

 supported by iron bars, laid across. A ground plan is 

 given in Fig. 99. A double kiln of this nature is 

 shown in Figs, no and in.

Many of these have been built since 1890, and are 

 designed to do their work with the utmost perfection 

 and economy of capital, labor, fuel, and maintenance. 

 These objects have been sought with special care by 

 the Pleasanton Hop Company, whose buildings em- 

 body many features suggested as desirable by science 

 and practice in all parts of the hop-growing world. 

 This model hop-curing establishment is described in 

 detail in the sketches, plans and photographs, Figs.
