IX. CHARACTER AND EXTENT OF INVESTIGATION 
MADE IN RELATION TO THE MANUFACTURE OF 
CHEESE IN CHEESE-FACTORIES DURING THE oh 
SON OF 1893. 
This station began its investigation relating to the manufacture 
of cheese in September, 1891, making eight preliminary experi- 
ments at the station and one at a cheese-factory. The investiga- 
tion was continued through the season of 1892, the work being 
divided between the station and various cheese-factories. In 
February and March, of 1893, some additional experiments were 
carried on at the station. 
In connection with the investigation carried on during the 
season of 1892, there were brought out some highly important 
results that were altogether new and unexpected. In order to 
confirm or modify these and some other results, it was decided to 
confine the investigation during the factory season of 1893 to 
fewer lines than in 1892, but to make the work on the selected 
lines more extensive. The object of this season’s work has, 
therefore, been to study, (1) the composition of normal factory 
milk, of whey and of cheese; (2) the conditions of manufacture, 
as found in actual practice; (3) the losses of milk constituents ; 
and (4) the relations existing between the composition of milk and 
the composition and yield of the resulting cheese. The entire 
work has been confined to commercial operations carried on in 
cheese-factories, and to the study of normal factory milk and of 
cheese made from normal factory milk. 7 ; 
It is designed to make this summary as complete in itself as 
possible, so that reference to previous bulletins will be necessary - 
only when the details of individual results are desired. Such 
detailed results of the season’s work of 1893 have been published 
in Bulletins 60, 61, 62 and 65. For the sake of comparison, the 
summarized a ate of the factory-work done during the factory 
ay “season of 1892 will be presented.
