and new ones are constantly being suggested, the purpose of — 
which is to secure a more complete separation of the fat in the 
milk from the larger bulk of milk serum. The great variety of 
methods of creaming in actual use indicate a rather chaotic 
condition of mind in regard to the whole subject. ee 
The experiments with methods of creaming, which are worthy 
of being called really scientific, have, for the most part, been very _ 
fragmentary. The result is that our knowledge of creaming 
methods is made up of fragments; a little has been done here, __ 
and a little there, and the results of different fragments often lead 
to contradictory conclusions. 
In view of the unsatisfactory state of our knowledge regarding 
the true comparative value of methods of creaming, it has been 
proposed to carry out at this Station an extended investigation of 
the different methods of creaming in use. By making the experi- — 
ments as exhaustive as is practicable, by planning and carrying _ 
them out under one management, by observing every precaution _ 
necessary to make the investigation practical and thoroughly scien- — 
tific, it is hoped that consistent results may be reached, which 
shall serve to show the true value of the methods dealt with. 
It is not proposed until later, probably in a bulletin, to discuss 
the nature of the process of creaming; but all know the very 
complex nature of the process and the marked influence exerted 
by slight variation in any one of many conditions; but these diffi- 
culties make the problem all the more worthy of the most careful 
treatment it can receive. 
After the most efficient methods of creaming have been deter- 
mined, then it is proposed to compare these with reference to 
efficiency in producing butter; for, as a rule, creaming is merely 
for the purpose of butter production. 
Plan of Experiments with Creaming by Dilution— Since the — 
practice of diluting milk with water for creaming has recently 
been attracting some attention, it was decided to take up this 
method as the first one for investigation. Work was begun 
early in September, but as the other Station work would permit 
only one set of experiments each week, the investigation has not 
progressed rapidly. However, the work will, from this i o aN 
be more rapidly pushed.
