so as to cover the entrance to the hive. The perforations, 

 being -§^ of an inch wide, are large enough for the worker bees 

 to pass through, but too small for the drones. Another kind 

 of entrance guard is shown below. It is an invention of Mr. 

 Alley's, and answers the double purpose of a trap as well as an

excluder. This guard has an upper compartment, into which 

 lead two wire-cloth cones, seen through the side openings in 

 the figure. The drones, after failing to make their way out 

 through the perforated zinc, finally force their way up through 

 the cones ; but not being able to return the same way they 

 become prisoners in the upper compartment. Should workers 

 go up through the cones, they can still make their way out 

 through the perforated zinc on top. From various conflicting 

 reports which have come under my notice, I am inclined to 

 doubt the efficacy of all these guards, as they are now made, 

 for the objects intended.
