of the chute should ho at least 6 feet from the floor of the aisle, 

 to permit a tall peri-ou to walk under same. Six feet 2 inches 

 is a better height. 



To make the bottom removable, nail a small cleat across the 

 under side of the 1x12 bottom, 11/2 inches from each end of same, 

 making this bottom board about 2 inches longer than the aisle 

 is wide, so that an inch will extend into the hole leading to nest 

 room, and another inch extending into the hole leading to the 

 fly pens. The cleats will prevent the board from slipping or 

 falling down and the board can be taken down, cleaned and 

 put back up easily. There should be two of these exits for each 

 nest room, one leading from each side.

 be used in connection with. Eight feet is the width of loft I 

 advise, but a foot or two wider than that is all right, especially 

 when the house is already built. Any space more than 10 feet 

 for the width of fly pen or nest room is unnecessary and a dis- 

 advantage. Such extra space can be utilized for unmated birds, 

 youngsters, feed bins, grit and nesting material,
