fruit, wasps following, and swarms of bluebottle flies finish the work. Nets to keep 

 off the birds, and hexagon netting stretched over the openings of houses where fruit is 

 ripening or ripe, are absolute necessities. Traps are then more effective. One of the 

 best is the glass " fly-catcher," baited with sweetened beer; the wasps enter from below, 

 and in striving to get out, fall in the liquid and drown. Another good trap is the old- 

 fashioned hand-light (Fig. 83). 



Take two hand-lights, place one on four pieces of wood to raise it about an inch from 

 the ground ; break four holes in the top of this hand-light about a quarter down the roof; 

 put a few pieces of ripe fruit on the ground under ; place another light of exactly the 

 same size on the top of this, laying moss all round the edge where the two meet. The 

 wasps, attracted by the pieces of fruit, take their fill, fly upwards, pass through the

holes into the upper glass, and never "think" of coming through the holes again. A 

 bell-glass trap also answers well. Place a large bell glass with a hole at the top on 

 three pieces of wood an inch thick, over a plate containing a syrup of sugar and beer, 

 or treacle, and above it place another glass closed at the top ; this glass, fitting closely 

 on the other and forming the trap, must be a size less, It acts in the same way as the 

 hand-light trap. An improvement on the bell glasses is found in the complete appliance 

 represented in Fig. 84, which first appeared in The Journal of Horticulture. These 

 traps are about 6 inches in diameter, and cost about 4s. Gd. a dozen. They are placed 

 on boards supported on three stakes, forming a tripod, and are easily baited with treacle 

 and water. Many wasps and other insects enter them and few escape, while the traps 

 are readily emptied.
