GENERAL HINTS 9 
As we have already seen, the egg from 
which the worker develops is precisely similar 
to that from which a queen springs; the rdéle 
of worker or queen is determined by the cell 
in which the egg is deposited. A grub in a 
worker cell gets but little ‘‘chyle’’ food—it is 
stopped altogether on the third day—and a 
mixed diet of honey and pollen. The drone is 
brought up entirely on the latter food. 
As soon as a worker grub leaves the cell it 
enters upon its life of labour. It is immature 
at this point, and as the air-organs, or trachea, 
are not fully developed, it cannot fly. Its first 
work, therefore, is that of ‘‘nurse’’ to the grubs 
still in the cells, and to supply the queen with 
‘“chyle’’ food. About a fortnight after leaving 
the cell, the young bee, if the weather be fine 
and warm, will venture out of the hive to try its 
wings, and on early spring days such numbers 
of them may be seen sporting near the entrance 
of the hive as to lead a novice to suppose that 
swarming was about to take place. The bee- 
keeper of experience, however, while rejoicing 
at the sight, will know that the exodus is partly 
due to the fact that some natural or artifi- 
cial food has entered the hive and that more 
must be supplied for the needs of the in- 
mates.
