Topics for study.—To build up a herd of cows intelligently and to 
eliminate those that are not paying their way, it is necessary to keep 
adequate records of produc- 
* tion, feeding, and breeding. 
A simple piece of home work 
under direction may be devel- 
oped so that the farm children 
may have valuable problems 
and at the same time obtain 
results that will be useful to 
the parents. Such aplan will 
establish a point of contact 
between school, home, and the 
child. 
The equipment for weighing 
is simple, consisting of a spring 
balance -reading in tenths of 
pounds (fig. 5), costing $3 to 
$5 if bought new, and a series 
of record sheets, which may be 
ruled by the pupil himself. 
What cows are being tested in 
the district? State the advan- 
tages of a milk record. How 
often should the milk be 
weighed ? 
Practical exercises.—Encour- 
age the pupils to adopt the 
practice of weighing daily the 
milk of each cow. A contest 
in milk production will stimu- 
lateinterest. Duplicatesof the 
record sheets may be posted 
side by side in the schoolroom, 
where the pupils will have 
an opportunity of comparing 
records. 
Illustrative material.—Cop- 
ies of milk records of the best 
dairy cows may be obtained 
and posted in the classroom for 
inspection. ‘The records made 
SS | by the pupils may be compared
