OBSERVATIONS AT FACTORY NUMBER FOUR IN 1900. 
Although Factory Number Four was, in point of time, one of 
the first with which we worked, the discussion of our observations 
has been reserved because of their greater number and interest. 
The first outbreak occurred early in October, 1900, but we 
were not called to the factory until late in the following month 
just as the factory was closing for the season. 
The building was an old one and had apparently received few 
repairs. The wooden floor of the making room was broken 
through in a number of places, allowing the floor slops to flow 
through upon the stones below, which were covered with the 
accumulated filth of years. The whey vat had not been cleaned 
in weeks because it was so old that on being emptied and dried 
a little it would no longer hold whey. As it was, the leakage 
from this source maintained a large mud hole. The drainage, 
which was by nature fair, had been neglected. The curing room 
and utensils were clean and in good order, and the maker was 
evidently doing his best under very adverse circumstances. 
Little could be done aside from explaining the cause of the 
trouble and urging: the necessity of a thorough cleaning up and 
preparation for the outbreak, which was almost certain to come 
the following season. 
WORK AND RESULTS AT FACTORY NUMBER FOUR IN 1901. 
July 17 we received word that an outbreak of rusty spot had 
occurred and we reached the factory the following day. A strik- 
ing change in the factory and its surroundings was evident. The 
drainage had been improved, a new whey vat and connections 
had replaced the old, the inside of the making room had been 
ceiled up, and, best of all, a cement floor had replaced the old 
wooden one and buried the filth beneath it. 
With the opening of the season, the factory had begun the 
manufacture of an extremely moist, uncolored, home-trade cheese 
of good quality, for which trade conections at good prices were 
quickly established. The resulting high dividends caused the 
return of the patronage which had left as the result of the finan-
