correspond to observed experience, we may deem them trustworthy. 
An examination of the monthly milk yields, as given for Ceres, and 
also the milk yields under the periods of trial, we ascertain that milk 
flow can be increased by the feed given after diminution arising either 
from effect of previous feeding, or from the natural diminution which 
comes from distance from calving. 
Examining our tabular data again, we can arrange another table, 
as below:

While last year, with cows in calf, we could trace no relationship 
between the amount of water drank and the milk yield, yet this year, 
with a farrow cow, such a relationship appears probable. Thus 
arranging according to the amount of water used:
