II. BIOLOGICAL CHAEACTERISTICS 

 1. Habit of Life 



The coKjny of the Japaness bee is inferior to iiidlifica in population. The 

 hive or box is built accordingly abot 33 X 33 X 'OO cm. Besides the fixed 

 hive, a maxable hive was offered by Tam.^ri (1889), but is not in usual use, 

 for the experience has pro\eci the bees like better the fi.xcd hive. When taken 

 in a new box, the co'on\- istablished \ery fine combs from ceilinij downwards, 

 arranged \-erticall)- and in i)arallel. yXccording to our old custom, a honey 

 dealer who visits the bec-\ard, takes out the honey, cutting across the height 

 of the upper half tiie combs of the honey store opened from the roof. The 

 remaining lialf of the store is left for the bees' support. In each hive the 

 honery har\'est is said to \-ieUl about I to 3 kivan (4-12 kg; of honery per 

 colony. 



If the ecological conditions are unfavourable, the bees abandon frequently 

 their hi\c. I observed case ()f tlic migration of the colony from Kumamoto, 

 the members of \\hi','h were prepairing to abandon the hi\e in the course of 

 about a month in the summer ilearth. Almost all cells were full of honey, but 

 the queen was \ery small in body size and no brood was found. The bees 

 were placed in so restless condition to run out of the entrance when the hive 

 was opened. I found after about 30 days that the hi\'e was vacant, when the 

 day of August 21st of i()22 broke. The propensity of m.igration may betaken
