Correlations. — Language: The pupils' reports provide written ex- 
ercises. Drawing: Have pupils make a sketch of a turn plow, locat- 
ing the parts — namely, handles, beams, share, moldboard, and land- 
slide. History : Have some member of the class prepare and read 
a statement giving an account of the community methods that have 
been and are now employed in turning land, including the kinds of 
plows used. Let this statement date as far back as reliable informa- 
tion may be secured. Arithmetic: Develop problems showing the 
economy in using large plows instead of small ones in turning land. 
A man with a 2-horse plow can turn 2 acres per day at a cost of $2.50. 
A man with a 1-horse plow can turn 1 acre per day at a cost of $2. 
Find the difference in cost in breaking fields of 10, 20, and 30 acres. 
LESSON TWO. 
SUBJECT : POULTRY. TOPIC : BROODING. 
Natural brooding. — The hen, the coop, handling the chicks, feed- 
ing, keeping down lice, protecting from enemies. 
Artificial brooding. — The brooder, testing the brooder, removing 
chicks from the incubator to the brooder, teaching chicks to find heat, 
regulating the temperature, feeding. Fireless brooders — location, 
teaching chicks to keep warm. 
Class assignment. — The teacher should read carefully Farmers' Bui. 
621 and give the class notes covering the foregoing outline. See also 
Farmers' Buls. 287 and 585. 
Practical exercises.^— (1) Club members should provide brood coops 
for their hens and chicks. See page 13, Farmers' Bui. 574, and page 4, 
Farmers' Bui. 62f. If artificial brooding is practiced, see pages 8 and 
10, Farmers' Bui. 624. (2) Require pupils that have no projects 
with poultry to submit written reports as to the kinds of brooding 
coops used with hens, and in case of artificial brooding the reports 
should cover descriptions of the brooders used. Successes and failures 
in brooding should be noted and accounted for. 
Correlations. — Language and drawing : Have pupils write descrip- 
tions and make drawings of the brooding coops used in connection 
with poultry projects or used at their homes. Arithmetic: Find the 
cost in labor and materials of the several brooders and brooding coops 
reported. How many broilers at the prevailing price would be neces- 
sary to cover the cost of each brooding coop? Does it appear to be 
economical to provide good coops? 
LESSON THREE. 
SUBJECT : FARM ANIMALS. TOPIC I GRAZING CROPS FOR HOGS. 
Temporary. — The accompanying table suggests a series of grazing 
crops that provide hog pasturage for almost the entire year. A selec-
