 fertility of a hen decreases with age, until at lengtn sue may 

 become entirely barren. By the same law, the fecundity of 

 the queen-bee ordinarily diminishes after she has entered her- 

 third year. An old queen sometimes ceases to lay worker-

 advantage, therefore, in hives which allow her, when she has

 moved. 



The "Worker-Bee. 



158. The workers are the smallest inhabitants of a bee- 

 hive, and compose the bulk of the pop- 

 ulation. A good swarm ought to contain 

 at least 20,000; and in large hives, strong 

 colonies, which are not reduced by swarm- 

 ing, frequently number three or four times 

 as many during the height of the breeding 

 season. F'S- 25. 



159. Their functions are varied. Tlie young bees work 

 inside of the hive, prepare and distribute the food to the 

 larvce, take care of the queen, by brushing her with their 

 tongues, nurse her, maintain the heat of the hive, or renew 

 the air and evaporate the newly-gathered honey (349), by 

 ventilating (261, 366). They clean the hive of dirt or-
