Table V is a percentage table based on the data given in the pre- 
ceding tables. It is believed that within reasonable hmits the per 
cent columns will be found useful in estimating the values of other 
classes of dairy cows. For example, the per cent column for the 
cow worth $80 at 3 years of age should be approximately accurate 
for the cow worth $70 at 3 years of age, and the per cent column for 
the cow worth $100 at 3 years of age should be approximately accu- 
rate for the cow worth $110 at 3 years of age. On the other hand, 
the per cent column for the purebred cow worth $300 at 3 years of 
age, could not very well be applied to cows valued at twice the 
amount at that age.
