PROGRESSIVE POULTRY CULTURE 199 



this open work is laid, a layer, one to three feet deep, of 

 dry straw, hay, pine boughs, or branches of deciduous 

 trees cut in full leaf. If more convenient one or more 

 layers of sacking, burlap or cotton cloth may be laid 

 upon the ceiling strips. In each end of the loft a win- 

 dow or ventilator is provided and these are kept open 

 continually, except, perhaps, in blizzard weather, when 

 the ventilator to windward may be partially or wholly 

 closed. 



The wind driving through the loft from end to end, 

 draws out the foul air from the apartments below and 

 fresh air sifts down through the straw without creating 

 strong drafts. 



The surplus moisture of the air is taken up by tne 

 straw and all danger of dripping water or white frost 

 on the interior walls of the house is avoided. 



A very sample and sensible method of ventilating a 

 house which has windows of two sashes is to raise the 

 lower sash six inches and fill the space below the sash 

 with a board. The air may then enter or pass out at tne 

 middle between the sashes without direct drafts disturb- 

 ing the fowls. 



'If it is desired to use ventilating flues an excellent 

 plan is to conduct the air into the room or house by a 

 pipe which passes from the outside into the house near 

 the floor and then extending upward has its opening 

 near the ceiling. The pipe for conveying out the foul 

 air should start near the floor and pass up through or 

 above the roof. 



In case~ of a brooder house or other building having 

 a chimney or smoke-flue, it is well to place one of the 

 ventilator pipes close to the smoke-flue. The air of the 

 ventilator pipe becoming warmed must rise and thus 

 there is forced ventilation of the apartment. 



In warm weather or in a mild climate where the 

 conditions allow, the hen-house should be thrown open 

 to the free air. Doorways, window spaces and other 

 openings, if need be, may have a covering of wire netting
