HOUSES FOR LAYERS. 37 



The part of the roof on the south side at A, A, A, 

 and nearly all on the north, consists of hinged doors 

 opening to the right or left, and overlapping when 

 closed, to shed rain. When it is desired to whitewash, 

 throw open all the doors, thus turning the house inside 

 out, take out the perches and nests, all built movable, 

 and there will be no nook or cranny of the woodwork 

 that the brush cannot be made to reach with ease, and 

 no lack of elbow room. This arrangement of doors 

 makes it convenient also to catch fowls upon the perches 

 by night. The doors should shut as snugly as may be 

 in coarse work, and the cracks unavoidably left around 

 them will afford all the ventilation needed in winter, 

 while in summer they may be opened more or less widely, 

 according to the weather. When it is warm, yet wet, 

 they may be partly opened and propped up, and boards 

 put across their edges to shed rain. It is very desirable, 

 under any plan for henneries, to build so that while 

 moderately tight in winter, they may be thrown open 

 on every side in hot weather ; for fowls are warmly clad, 

 and suffer much from the heat when in buildings made, 

 as is too frequently the case, only with reference to the 

 cold. The doors which form the north roof project 

 six inches at the ridge, to keep out rain, as there is no 

 ridge cap. 



The two windows in the south roof are glazed, 

 greenhouse fashion ; that is, with overlapping panes, 

 that snow may slide from them readily as soon as loos- 

 ened by the warmth inside. They are two feet high 

 and three feet wide, and set eighteen inches from the 

 peak of the roof. . A strip of tin is fastened over the 

 upper part of the sash, and the sides and bottom of the 

 sash overlap the roof, to be rain-proof. The shutters,

 occasions, elsewhere referred to, are hinged to the lower 

 part of the sash, and when opened, as in the illustration,
