16 BULLETIN 305, U. S. DEPARTMENT OF AGRICULTURE. 



Practical work. — List all plants studied and record the facts indi- 

 cated in the above questions in class notebook. 



Collect seed from the different field crops and mount and label. 

 Seeds or fruits of shrubs should be collected, mounted, and labeled. 

 In case of fruits they should be thoroughly dry before storing or 

 mounting. 



Keep the schoolroom decorated with field crops. 



Correlations. — Language lessons: Making records of the practical 

 work and descriptions of plants and their uses provide sufficient 

 written work. 



Drawing: Make drawings of ears of corn, pea and bean pods, 

 pumpkins, fruits, and seeds of shrubs. 



Geography: Have pupils make a product map of the school dis- 

 trict. Outline the district as accurately as possible and paste on 

 seed of the different kinds of crops being planted or harvested this 

 month. 



Arithmetic : 



(1) Examine an ear of corn of average size. How many rows has it? How 



many grains per row? How many grains per ear? How many grains in 

 a pint measure? How many grains per bushel? 



(2) Add two more rows to the ear. How many grains would these add? How 



many such rows would be required to make a bushel? . 



(3) By selecting his seed a farmer added 5 grains to each row on the ear. If 



each ear has 16 rows, how many grains are added to each ear? From how 

 many such ears would this number of grains have to be shelled to fill a 

 pint measure? 



(4) From the foregoing statements develop other exercises. 



ANIMALS. 



Review and continued work. — Keep up the annual population 

 studies. Before they leave for the winter, classify all the birds that 

 are summer residents according to their manner of catching insects. 

 As new birds arrive observe them carefully and classify them in the 

 same way. The four methods are: (1) Climbing over buds, leaves, 

 and limbs for insect eggs; (2) searching on the ground for cutworms, 

 crickets, and grasshoppers; (3) looking among leaves and branches 

 for caterpillars; and (4) perching in some open place and darting 

 into the air after flies and beetles. Keep records of the work in 

 class notebook. 



This is the season of abundant food supply for all kinds of animals. 

 Wild mammals are grouped into three classes according to the man- 

 ner in which they make provision for the winter: (1) Those that store 

 up nothing for winter, like the rabbit and fox; (2) those that collect 

 a large supply and store it away in a hollow tree or in a burrow, like 

 the chipmunk or ground squirrel; and (3) those that consume a great
