Most of the Bees are Workers. They are smaller than either the Queen Mother or the Drones, and they gather all the honey, make all the wax, build the comb, and feed the babies. They keep the hive clean, and when the weather is very warm, some of them fan the air with their wings to cool it. They guard the doorway of the hive, too, and turn away the robbers who sometimes come to steal their honey. In these busy homes, nobody can live long just for himself. Everybody helps somebody else, and that makes life pleasant. The Queen Mother often lays as many as two thousand eggs in a day. Most of these are Worker eggs, and are laid in the small cells of the brood comb, which is the nursery of the hive. A few are Drone eggs and are laid in large cells. She never lays any Queen eggs, for she does not want more Queens growing up. It is a law among the Bees that there can be only one grown Queen living in each home. The Workers, however, know that something might happen to their old Queen Mother, so, after she has gone away, they sometimes go into a cell where she has laid a Worker egg, and take down the waxen walls between it and the ones on either side to make a very large royal cell. They bite away the wax with their strong jaws and press the rough edges into shape with their feet. When this egg hatches, they do not feed the baby, or Larva, with tasteless bread made of flower-dust, honey, and water, as they would if they intended it to grow up a Worker or a Drone. Instead, they make what is called royal jelly, which is quite sour, and tuck this all around the Larva, who now looks like a little white worm. The royal jelly makes her grow fast, and in five days she is so large as to nearly fill the cell. Then she stops eating, spins a cocoon, and lies in it for about two and a half days more. When she comes out of this, she is called a Pupa. Sixteen days after the laying of the egg, the young Queen is ready to come out of her cell. It takes twenty-one days for a Worker to become fully grown and twenty-five for a Drone. In the hive by the cedar tree, the Queen Mother was growing restless and fussy. She knew that the Workers were raising some young Queens, and she tried to get to the royal cells. She knew that if she could only do that, the young Queens would never live to come out. The Workers knew this, too, and whenever she came near there, they made her go away. The Queen Larvae and Pupae were of different ages, and one of them was now ready to leave her cell. They could hear her crying to be let out, but they knew that if she and the Queen Mother should meet now, one of them would die. So instead of letting her out, they built a thick wall of wax over the door and left only an opening through which they could feed her. When she was hungry she ran her tongue out and they put honey on it.
