ARITHMETIC. 
Develop problems on the cost of keeping cows in the different homes of the com- 
munity. Have pupils bring data as to the rations fed daily to the cows and from such 
determine the nutritive value and let it be shown whether the ration is balanced 
or not. Where the Babcock tester can be had let the milk of the various cows of 
the community be tested and from these facts develop problems showing the profit- 
ableness or unprofitableness of the individual cow, and by a comparison of the kind 
and cost of rations and returns from each cow let it be shown whether the profit or 
loss is due to the feeding or to the animal. Special problems in nutritive ratios 
should be developed for the benefit of the pig and poultry club members. This 
entire month can be spent in working out balanced food rations for the various farm 
animals of the community, combining foodstuffs in these rations that can be had

at the least cost. As a basis for these exercises the following publications are sug- 
gested for use: Farmers' Bulletins 22 (Rev.), Feeding Farm Animals; 346, The Com- 
putation of Rations for Farm Animals by Use of Energy Values; and 411, Feeding Hogs 
in the South. 
EXCURSION'S AND PRACTICAL WORK. 
Excursions for comparison of out-of-date and modern farm machinery, gins, and 
grain mills should be made. Trips should also be made for the purpose of practice 
in scoring farm animals. 
Practical indoor work in scoring seeds should be engaged in during the months 
of December and January (fig. 5). Have specimens brought to the school by club 
members and the work carried on under the supervision of the teachers. When 
possible, have farmers bring animals to the school grounds for practice in scoring.
