 REFERENCES AND REMARKS TO FIG. 2. 



D, doors, the double one at the bottom having a sill so low a wheelbarrow can .be run over it, 

 outside door being of gauze. 



W, windows, all of which have wire gauze screens outside, and hinged to swing out. Screens on 

 four south windows to extend 4 inches above upper jamb, with >f-inch space. 



Posts 14 feet. Studding, to chamber, alternate 13 and 18 inches apart (?) Side studding 12 feet 

 long and 1 foot apart. 



Floor, double, one foot apart, and with grouting. 



Cellar and house mouse proof. 



The entire north side of the building is for a shop. This is 12x30 feet. It 

 has a pump from the cistern below, and stairs to the chamber above. It has 

 an outside door, four windows, and a door into each of the other rooms. 

 There will also he a stove in this room. In winter, then, when we have a 

 fire in either room, the chimney will be heated, and the air drawn from the 

 bee-cellar. The wind, too, passii)g over the chimney, will suck the air from 

 the cellar. In both cases the air is supplied through the long sub-earth pipe, 

 and IS so tempered by the temperature of the earth, and is kept sweet and 

 pure. This is both theory and demonstrated fact. This room is large 

 enough so that a small engine and some machinery can be introduced if 

 desired. I find that this house, large enough for a large apiary, can be built 

 for $600; and for safety and convenience I believe it fills the bill. I cannot 

 agree with Mr. Heddon that we had better have double-walled houses above 

 ground. I think the cellar far better and more convenient.
