MANAGEMENT OF BEES. 
9 
In the front view of the Hive, you will see a venti- 
lator, covered with fine wire gauze, or perforated tin. 
The ventilator is 1 inch wide, and 5 inches long, cut 
through the front board 1 inch below the bottom of the 
chamber floor, to let the breath and bad air escape from 
the Hive. I cut the gauze larger than the mortice 
through the front board, and tack it or perforated tin 
over the mortice. Then I mitre a strip 3-8 of an inch 
thick, and 3-4 of an inch wide around the mortice, over 
the gauze, taking care that my mitre and mortice shall 
he exactly of a size. This gauze should be made of 
fine wire — such as is used for milk strainers — or perfo- 
rated tin, with the holes so fine that no insect can enter 
them, and pass into the casement. 
The tube (which is the only entrance) should be put 
in front, near the bottom of the Hive. The top of the 
tube must be even with the top of the bottom plank. —
