The Manipulation of Bees

moved and a float must be used to prevent bees from drown¬ 
ing. The Alexander feeder (Fig. 106) is useful mainly for 
stimulation. It may be placed under the rear of the brood- 
chamber if the bottom board is moved forward, but this 
often causes robbing and a better plan is to place it in a 
collar under the brood-chamber as shown in the illustration. 
For feeding small quantities, a “pepper-box feeder” (Fig. 
107) may be inverted over the brood frames in .an empty 
hive-body. Mason jars may be used in the same way, 
special pierced covers being sold by dealers in beekeeping 
supplies. For rapid feeding in the fall, a large pan in an 
empty super (Fig. 108) is perhaps best. Green grass should 
be thrown in the syrup to give support to the bees while 
feeding, this being better than excelsior or chips as it does 
not absorb the syrup. The empty super and pan may be 
placed under the brood-chamber for late feeding, in which 
case the bees take the syrup more rapidly. 
Uniting. 
If a colony becomes queenless in late fall, it is usually 
not profitable to give it a queen, but it may be united with a 
normal colony to save the bees. It is not wise to try to 
winter weak colonies, but if two or more are united to make 
a strong colony, keeping the best queen, the risk in wintering 
is reduced and better results are obtained in the spring. 
It is also more profitable to unite weak colonies in the spring 
than to build them up. 
Intluence of hive odor. 
Every colony of bees has a distinctive odor by which bees 
recognize individuals from their own colony, normally 
resenting the entrance to their hive of those from other 
colonies. In uniting colonies, the different odors may be 
hidden by smoking both vigorously. Tobacco smoke may 
be used, but if too much is employed the bees become stupe¬ 
fied. If bees are stupefied by tobacco smoke, chloroform or 
other anaesthetics, they lose their memory of former locations
