BEST NEST BOX CONSTRUCTION. 



When the nest boxes are built of lumber (one-half an inch or five-eighths of an 

 inch thick) the above construction should be employed. The bottoms are not 

 nailed, but slide in on cleats, as shown. The result is a sliding shelf. This shelf 

 may be pulled out at cleaning time and a better and quicker job of cleaning done. 



The nest bowls may be screwed directly to the bottoms of the above nest boxes. 

 If that is done, it will not be necessary to screw the nest bowls to blocks of wood, 

 to give them stability. 



The nest boxes should be from ten inches to twelve inches square.
