Here is another record of what can be done. This curve 

 shows the average of my heifers and cows at the different ages, 

 and this curve shows the average production of all cows in the 

 Unitd States. This was figured by the University of Illinois. 



Here is something that you will find everywhere they have 

 statistics. The average cow's production is highest at 8 years 

 of age. There are a great many cows that will be good pro- 

 ducers after 8 years^ but the average will produce 8 years, and 

 after that there will be a decline, for the cow has seen her best 

 days. 



In connection with weighing the milk and keeping the cost 

 of the milk, we charge up the cow with all the labor that it takes, 

 machine labor, horse labor, and man labor.
