I. ORGANIZATION OF THE WORK. 
All work connected with making butter from the milk of the 
dairy cattle under experiment had to be organized from the 
beginning, and to this the chemist turned his attention as soon as 
_was practicable after entering upon his duties at the Station. 
It was planned to set milk from each cow on those days on 
which analysis of the milk was made and to make butter from the 
same. Commencing August 18, 1890, the plan has been regularly 
carried out. 
All work connected with making and keeping the records has 
been under the immediate charge and supervision of the chemist. 
The details of creaming and churning have been mainly attended 
to by the Station dairyman. Most of the analytical work and the 
; extensive calculations connected with keeping the records have 
been attended to personally by the chemist. 
Up to December first, eighty-four churnings were made. 
IL Ossects oF THE WORK. 
The first and main object of the work is to study the breed 
characteristics in production of butter. This necessarily involves 
an extended study of the influence of foods upon butter yield as 
regards both quantity and qualtity. 
A study will also be made of the various conditions which 
affect the efficiency of creaming, churnability of cream, etc. The 
plan is to vary the method of treatment from time to time, treating 
the milk of all the cows with uniformity, as nearly as possible, 
and noticing the different effects of variation of treatment.
