Note to the Teacher.—This lesson gives all the details 
of compounding rations for farm animals. To make stu- 
dents thoroughly familiar with ration making require them 
to prepare other rations, using feeds available at their 
homes. Members of the class should be asked to place 
their work on the blackboard, where careful comparisons 
may be made. This will develop into very interesting 
work, particularly if the cost of each food is also in- 
cluded. Calculate the variation in cost for large herds 
covering half-year or yearly periods.
