8 STORRS AGRICULTURAL EXPERIMENT STATION. 
and Italy. The results of Prof. Conn’s observations on bovine 
tuberculosis are epitomized in Bulletin No. 19 of the Station, 
on “The Present Condition of Bovine Tuberculosis in 
Europe.” They are given in more detail in an article on the 
same subject in the present Report. Another article by Prof. 
Conn gives the results of his observations on the practical ap-. 
plications of bacteriology in European dairying, especially in 
the handling of milk and the making of butter and cheese. 
Much more attention has been given to these subjects by 
bacteriologists and practical dairymen in Europe than in the 
United States. The results of this foreign experience as col- 
lated by a specialist, with such unusual opportunity for per- 
sonal observation, can hardly fail to be of particular interest 
to farmers in Connecticut and elsewhere. <A large amount of 
space is accordingly given to them in the present Report. 
The experiments with tuberculous cows at the Station, of 
which an account was given in the Report for 1897, have been 
continued. Some of the more important and interesting re- 
sults of these investigations are given in the present Report. 
These experiments will be continued during the coming year. 
The experiments on the vacteria of milk and cream and 
their influence on butter-making, which have been carried on 
by Prof. Conn and his assistants for several years, and have 
been described in the Reports of the Station, are being con- 
tinued. 
FEEDING OF COWS AND SHEEP. 
The studies of the rations fed to milch cows, and their effects 
upon milk production, which have been carried out for several 
years past with the Station herd and with private herds in 
different parts of the State, have been continued, but on a plan 
somewhat different from that of previous years. ‘The length of 
the individual experiments has been increased to three months. 
During the first half of this period the rations found in pre- 
vious use were continued, and during the last half a new ration, 
suggested by the Station, was adopted. These later rations 
were determined according to the milk-producing capacities of 
the cows rather than their avoirdupois weights, for reasons 
described in detail in the Report of last year. The experi- 
ments of the past year were not decisive. Experience is neces- 
sary for the working out of the details of the experimental 
method, and the experiments are being continued.
