102 MAINE AGRICULTURAL EXPERIMENT STATION. 



each side. There are ten windows in the front wall, equal 

 distances apart. The bottoms of these windows are 8 inches 

 from the floor. There are also five windows in the back wall 

 close up to the plate. These windows all have six lights each 

 of 10 by 12 glass. 



All sash are in two parts and slide up or down to admit fresh 

 air and keep the house cool in warm weather. All windows 

 are double. There are ten small doors each io by 12 inches, 

 placed close to the floor, along the front wall, through which 

 chicks can pass in and out. All doors are double. 



Two galvanized iron ventilators, each 10 inches in diameter 

 and 6 feet 6 inches high, with projecting hoods at the tops, 

 extend from the inside of the room up through the ridge, and 

 furnish sufficient means of ventilation during cold weather. 

 Ventilation is regulated by means of a shut off at the ceiling. 



There are ten breeding pens, each 6 feet by 10 feet and 8 

 inches. The partitions have an 8 inch board at the bottom 

 with 3 feet of i-inch mesh wire above. A walk 2 feet and 6 inches 

 wide extends along the back of the building. The doors which 

 lead from the walk to the pens swing both ways and are wire 

 covered. A Peep O'Day brooder is placed in each pen with 

 the lamp door opening into the walk. Each of these pens 

 accommodates about 60 chicks in winter or j^ or 80 in spring 

 when they can get out into the yards. 



The building being low is kept warm enough in winter by 

 the ten brooder stoves, and the temperature under the hovers 

 is easily kept so that it is found in the morning about as left the 

 night before. 



The cost of this building without the brooders was S235. Of 

 this amount Si 60 was for material and $75 for labor. 



FEED HOUSE. 



The east end of the brooding house is 25 feet west of the west 

 end of the breeding house. The fronts of both buildings are 

 on the same line, facing the south. The 25 feet space is filled 

 in with a small temporary cook and feed mixing-house, which 

 opens into the breeding and brooding houses. It contains a 

 supply of running water, mixing trough, feed bins, water heater, 

 clover cutter, bone mill, etc.
