the workers, however, knew that there must be young queens growing up all the time. supposing something should happen to the queen-mother, what would become of the swarm if there were nobody to lay eggs? so after she had laid several thousand worker eggs, and it was time for the young ones to hatch, they decided to change some of the babies into young queens. and this was easy enough. when they were out for honey, they filled the pockets on their hind legs with pollen, the yellow dust that is found in flowers. this was to be mixed with honey and water and made into bread for the babies, who were now awake, and looked like tiny white worms in the bottom of their cells. then they made some that was almost like sour jelly, and put it in a few of the worker cells for the tiny white worms, or larvæ, to eat. the larvæ that eat this jelly grow up to be queens, and can lay eggs. those that eat the common bread are either drones or workers, whichever their mother had planned them to be.
