tilation in varying degree according to the seasons, and tlie 

 temperatures of the seasons. 



Muslin covered openings are recommended for the double 

 purpose of light and ventilation. However, they are not an 

 unmixed good and are not as effective for these purposes as 

 they are recommended to be. They soon get dusty, so that 

 they do not ventilate freely, and in the course of a season get 

 so dirt}' that they shut of? very much light. The latter objec- 

 tion is not so great in the long days of summer as in the 

 short days of winter. 



Openings or windows protected by hinged slatted doors, 

 to keep out the weather and prevent direct air currents, are 

 much more effective for ventilation, and can be fastened back 

 and the windows closed, when not needed as ventilators. 



In the summer, if the house gets overheated because of 

 the glare of the sun on a large amount of glass, some of the 

 glass can be washed over with a solution of Whiting and 

 water, and this will protect from the sun's glare without 

 excluding much light. 



As to the open front, this is a good summer proposition, 

 if the top of the front opening is below the level of the roosts, 

 and some distance away. If the opening is above the level 

 of the roosts, especially in narrow houses, so that the wind can 

 blow in directly, look out for trouble in fall and spring. 



In winter, an open front may prove a delusion and a 

 snare, in extreme temperatures. This danger can be lessened 

 by covering these openings with muslin ; but the covering of 

 these openings will also shut out a great amount of needed 

 light and sunshine. 



A closed house is also a source of danger, as fowls need 

 plenty of fresh air. There should always be an opening, such 

 as a window part way open, even in the severest weather. 

 When the outside temperature gets down to zero or below, 

 more ventilation will be secured, and the air will circulate 

 more freely, through a window open three or four inches, 

 than with all the windows on one side open to their full 

 capacity in the summer time. 



If you have an open front, and find the birds, on cold 

 days, huddled up to keep warm at the side farthest from your 

 open fro it, close the openings to a point dictated by observa-
