FOE SITTERS IN MILD CLIMATES. 85 



in the description of Fig. 25, and to operate the feed 

 shelves, six in all, which are suspended in the main 

 building and in the small yards over the dotted lines in 

 the cut. The construction and working of these shelves 

 is explained elsewhere. See Figs. 17 and 18. A trans- 

 verse section of one of the shelves hung up in the main 

 building is shown at J, Fig. 29. See description of 

 various modifications of feed shelves, the simplest being 

 the best. In Fig. 27, the long, narrow space, a, is occu- 

 pied by nests and c by nest passages, both being of the 

 kind previously described. A few of the nests are shown 

 divided off in the cut at b and a few of the nest passages 

 are divided off at T. Compare Tin Fig. 27 with Tin 

 Fig. 25 and with Tin Fig. 29, keeping in mind that the 

 floor of each nest passage consists of a treadle. The 

 alley, x, for the attendant, previously described, being 

 sunk 2 1-2 ft. below the ground, the end rooms, m, m, 

 are also excavated to the same depth for better con- 

 venience, and steps outside the building near the out- 

 side doors, h, Ti y lead from the ground level to the con- 

 tinuous pit or shallow cellar, m x m. At each end of 

 the long alley and near the door, h, a small ell or pro- 

 jection will be seen, attached to the main building. The 

 railroad extends into these ells, which are just large 

 enough and high enough to hold the car, so that it will 

 be out of the way when not in use. A section of the 

 railroad track four feet long, situated between' the ell 

 and where the row of nests begins, is movable, that is, a 

 piece of each rail is hinged at one end and can be turned 

 up out of the way when railroad and car are not needed. 

 Gates, to permit fowls to pass from J^to y, are shown 

 at G, G, G, G. Figure 30 illustrates one of these gates, G, 

 made of wire netting, attached to a light wooden frame, 

 and G in Fig. 28 shows a gate in a perpendicular posi- 

 tion and also, by means of dotted lines, a horizontal 

 position. The yard, y, in Fig. 28, is roofed over. As
