2 of milk from all the cows, upon all foods fed, during 
the four years was as follows: Total cost, 100:192; net cost, 
100:262. 
This Ppeeccnts the results rah may be secured even with 
good animals by attention to the economies of feeding; a dif- 
faroticd of ninety-two per cent in total and 162 per cent in net 
cost of production of milk as the result alone of feeding; or by 
careful selection of animals adapted to the purpose of milk pro- 
duction, it is seen, even with so limited a number of animals as 
were under investigation, and by carefully selected rations a dif- 
ference of 272 per cent in the total and 451 per cent in the net 
cost of production of milk. 
What other large industry presents such a grand margin of 
possibilities ? 
The following table presents in a condensed summary the 
results given elsewhere in detail, which have thus far been secured 
with the several animals of different breeds which have been 
secured for an extended investigation. 
Twelve of these have already been at the Station, upon an aver- 
age of five and one half-months ( October first), and while of course 
itis obviously too early to attempt anything in the nature of gen- 
eralization, it is thought that a study of the data already secured 
may prove both of interest and value. 
It.will be obsered that, as a rule, the younger the animals the 
‘less food required to produce a given increase in weight as would 
naturally be expected; as also that their relative increase in 
weight decreases with their age, although as yet they are all 
growing, making satisfactory increase.
