IOO MAINE AGRICULTURAL EXPERIMENT STATION. 



hasped, except when used for the feeding of the morning's mash. 

 Eight inches above the floor, a slot 8 inches wide and 4 inches 

 high is cut through the plank partitions between every other 

 pen. Galvanized iron pans 4 inches deep, 12 inches square at 

 the top and 10 inches square at the bottom, are slipped into the 

 slots, and each one accommodates two pens with water. A cleat 

 on each side of the slot at the bottom is necessary to give suffi- 

 cient base rest to the pans. Shelf troughs, 10 inches above the 

 floor, contain grit, shell and bone. 



A small box, with sloping cover, is hung on the wall in each 

 pen and receives the eggs as they are collected during the day. 



Partial ventilation is provided by eight ventilator places in 

 the front wall between the studs. These places between the 

 studs are 3 feet wide by 4 inches deep, and open into the pens, 

 6 inches above the floor. They open on both sides of every 

 other cross partition and so ventilate from every pen. They 

 have an upright draft of about 10 feet, and open out just under 

 the plate, the openings being protected by sloping board covers 

 to prevent inward currents of air when the wind blows hard 

 against them. 



All windows are double. Eight of the large outside ones 

 are hinged at the tops and are kept hasped out one foot at the 

 bottom except in the roughest weather. This furnishes excel- 

 lent ventilation without drafts as the position of the outside 

 windows prevents strong currents of air from entering. 



When the temperature has fallen to 10 degrees below zero, 

 water has frozen quite hard in the breeding house and egg 

 production has been seriously checked. We shall probably pro- 

 vide five or six large oil stoves for use in this building during 

 nights in extreme weather, and try to keep it above the freezing 

 point at all times. 



Double doors, 10 inches wide and 12 inches high, are placed 

 under the walk and admit the birds to the front yards which are 

 10 feet wide and 75 feet long. Similar doors in the back wall of 

 each pen. under the roost platforms, allow the birds to pass to 

 the back yards, which are of the same width but somewhat longer 

 than those in front. These back yards are particularly for use 

 in warm weather. 



The frame and outside boarding of the building are of hem- 

 lock, costing S8 per M. at the mills, a mile away. The doors
