DOMESTIC ANIMALS 211 



kept out by^ tin-lined entrances. The widespread fear of 

 the kingbird seems unfounded. He rarely eats anything 

 but drones, and very few of them. This is also true of the 

 swallow. Toads, lizards, and spiders are, however, true 

 enemies of the honeybee. 



EXERCISE 



Can you recognize drones, workers, and queens ? Do bees usually 

 limit their visits to one kind of blossom on any one trip? What 

 effect has the kind of flower on the flavor of the honey produced ? 

 What kind of flowers should the bee keeper provide for his bees? 

 Is the kingbird really an enemy to the bee ? Apply to Division of 

 Entomology, Washington, D.C., for Bulletin i, on the honeybee. 



SECTION XLVI WHY WE FEED 



In the first place, we give various kinds of feeding 

 stuffs to our animals that they may live. The heart beats 

 all the time, the lungs contract and expand, digestion is 

 taking place, the blood circulates through the body- 

 something must supply force for these acts or the animal 

 dies. This force is derived from food. 



In the next place, food is required to keep the body 

 warm. Food in this respect is fuel, and acts in the same 

 way that wood or coal does in the stove. Our bodies are 

 warm all the time, and they are kept warm by the food we 

 eat at mealtimes. 



Then, in the third place, food is required to enable the 

 body to enlarge, to grow. If you feed a colt just enough 

 to keep it alive and warm, there will be no material present 

 to enable it to grow ; hence you must add enough food to 

 form bone and flesh and muscle and hair and fat.
