Honey and wax. The honeybee gathers nectar, which she 

 swallows, keeping the fluid in her crop until her return to the hive. 



Here it is forced out into 

 the cells of the comb. It 

 is now thinner than honey. 

 To thicken it, the bees 

 swarm over the open 

 cells, moving their wings 

 very rapidly, thus evapo- 

 rating some of the water. 

 A hive of bees may make 

 between 30 and 80 pounds 

 Of honey during a season. 

 Over 60,000,000 pounds of 

 honey is produced in this 

 country every year. 



Practical Exercise 17. Re- 

 port on a trip to an apiary, or 

 on a study of an observation

Birds as food. Birds, 

 both wild and domesti- 

 cated, form part of our 

 food supply. But our 

 wild game birds are dis- 

 appearing so rapidly that 

 source of food. Our domestic

Bee colonies spread by swarming. If hives are not 

 provided for the swarming bees, they will find homes 

 for themselves in hollow places or on trees, as shown 

 above. 



we cannot consider them as a 

 fowls, chicken, turkeys, ducks, 

 supply. Eggs of domesticated fowls are of great importance as 

 food, and egg albumin is used for other purposes, such as clarify- 

 ing sugars and coating photographic papers. 



Practical Exercise 18, Give a report on the different birds in your locality 

 that may be used as food. 



Mammals as food. When we consider the amount of wealth 

 invested in cattle and other domesticated mammals bred and used 

 for food in this country, we see the great economic importance of 

 these animals. In 1928 nearly $3,000,000,000 worth of meat-pro-
