one-third as wide as the desired length of the bottom- 
board. Let two pieces be 18’/, in. long, and two others 
vin. The cleats should be 1x1'/, in., and 2 in. square, 
respectively, and 27'/, in. in length. The ventilator, and 
support for the frames are arranged precisely as in the 
small bottom-board. 
It would be well to omit cutting the channel over 
which the hoop iron projects to support the frames, with- 
in 7/, in. of each edge, which may readily be done when 
using machinery, but if cut with a hand plane, it must

be cut through, and the space afterwards carefully filled 
with wood or leather. Let the hoop-iron come short also, 
one inch. The entrance should be divided in two parts, 
as directed. Bore two °/, in. holes, one in the center of 
each end, to receive dowel pins (fig. 36). 
The sides, or front and back, are 27’/, in. long, and 18 
in. wide. On the inside corners of the ends cut a rabbet 
*/, in. deep by ’/, in. wide, in which to fit the ends, which 
are 177/, X18 in. 
Both ends and sides should be of matched lumber, as 
they will be less liable to check than if made of one piece. 
Each part should be cleated two inches from each end, 
with cleats 2 in. wide, '/, thick, and 17 in. long. Nail
