one-third as wide as the desired length of the bottom- 

 board. Let two pieces be 18'/^ in. long, and two others 

 7 in. The cleats should be 1 X l'/, in., and 2 in. square, 

 respectively, and 37'/, 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 y, 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 y^ in. holes, one in the center of 

 each end, to receive dowel pins (fig. 36). 



The sides, or front and back, are 27y, in. long, and 18 

 in. wide. On the inside corners of the ends cut a rabbet 

 y, in. deep by y^ in. wide, in which to fit the ends, which 

 are 17y, X 18 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, y^ thick, and 17 in. long. Nail
