THE ALTERNATE ART) PARALLEL SYSTEMS. 



or ell must be added to the main build- 

 ing, to give the lever room to describe 

 an arc. 



The rooms, or stationary boxes as we 

 have named their equivalent in other 

 outs, for the separate flocks may be seen 

 on this ground plan .if the reader will 

 imagine a line drawn from each block, m, 

 through k, c 2 , c\ and thence to the wall. 

 By referring to the transverse section, Fig. 

 117, it will be obvious that each flock will 

 have a nesting apartment and a roost, a 

 ladder being furnished for the convenience 

 of the birds. The need of a piece of coarse 

 wire netting under and at one side of the 

 call cylinders will be evident, to Keep the 

 fowls away and, at the same time, allow 

 feed to drop on the floor. 5 



Among other merits of the parallel plan 

 for arrarging the tilt boxes, we enumer- 

 ate : First, the birds have the benefit of 

 the space under the passage, g ; second, 

 the nests, the perches and all the feed 

 cylinders are very convenient of access by 

 the attendant, and third, the tilt box is 

 narrow in proportion to its length, thereby 

 facilitating the tilting. Build all the 

 boxes narrow and of thin, light lumber. 



The tilt box is, as before stated, one 

 continuous box supported by the axle, I, 

 which rests on the blocks, m, in such a 

 position that when the tilt box is level 

 its underside is one inch higher than the 

 upper surface of the floor,/. The con- 

 tinuous box, several hundred feet long, is 

 divided into apartments by board parti-
