used in locating the source of trouble in each case were so 
simple that it is hoped many may profit by the suggestions and 
be inspired to help themselves. 
With sweet flavor in Cheddar the situation is somewhat dif- 
ferent. Here we have to deal with a trouble which is both wide- 
spread and of long standing in the State, where it produces an- 
nually a large economic loss. This trouble has found its way 
into some of the cleanest and best managed factories, and there 
it remains despite the exertions of some of the most careful 
makers, In the past their efforts have been paralyzed by an 
entire lack of information as to the nature of the cause of this 
trouble. 
While the discovery of the true cause is naturally the first step, 
especially in a biological problem, it should be followed by a 
study of the place of residence or manner of constant introduc- 
tion into the factory before attempting the third and most prac- 
tical step—the formulation of practical methods of combating 
the trouble. 
It is our hope to follow out each of these steps in the order 
given in our attempt at aiding in the control of this widespread 
evil. 
In attacking problems calling for training along such diverse 
lines the Bacteriological Department and the Dairy Expert have 
joined forces for the general good; but each assumes the responsi- 
bility for the correctness of certain portions of the work. The 
Bacteriological Department is solely responsible for the isolation 
and preparation of the cultures and starters, and the judgment 
of the Dairy Expert has been relied upon in manufacturing the 
experimental cheese and in deciding upon the similarity of the 
flavors there produced to those of the troubles under investiga.

CARD OF THANKS, 
Owing to the unsatisfactory nature of conclusions based on 
the sense of smell, we have improved every opportunity for ob- 
taining the verdict of many of the cheese experts of the State, 
and in the matter of samples we have been very materially aided
