96 Atf EGG FARM. 



In all the other cuts these shafts were purposely placed 

 wide apart, to give a plainer view of the cords, arms 

 and other parts. In Fig. 29, for the same reason, the 

 roost, r, was entirely omitted. It is 144 ft. long, and 

 its floor, set on a slant downwards toward the outside of 

 the building, is only 3 1-4 ft. wide, so that it will not 

 intercept the grain which falls from the shelf. One 

 perch only is needed, and this stands 18 in. above the 

 roost floor and is 144 ft. long.
