AGRICULTURAL EXPERIMENT STATION. 19 
very suddenly. Symptoms by which stockmen may recognize 
the disease, especially on examination post-mortem, are 
given quite fully; also statistics concerning the extent of the 
spread of this disease in Minnesota and estimated losses. An 
outbreak of the disease which appeared on the University 
Experimental Farm was quite serious, on account of its 
financial loss, but it gave us almost ideal opportunities for 
studying the disease. Attention is drawn to the fact that 
certain cases of hemorrhagic septicemia very closely resemble 
cases of milk fever, and may be easily mistaken for such in 
cases of disease developed within a few days after calving. 
A carefully prepared table is presented, which offers a very 
complete comparative study of hemorrhagic septicemia, an- 
thrax, symptomatic anthrax and infectious cerebro-spinal men- 
ingitis. This was deemed important, because these diseases 
were very easily confused by stock men, and often in obscure 
cases by veterinarians. The diagnosis is especially important 
for anthrax, symptomatic anthrax and black-leg. 
Proposed Station Work.—Quite extensive plans are under 
way for the station work in this division during the coming 

year. One series of proposed experiments deats with a practi- 
cal study of ventilation problems from a physiology stand- 
point. Another series of experiments has been outlined with 
a view of determining the relative desirablity of various 
methods of disinfecting large stables, the following points to 
be especially considered: Rapidity, expense, difficulties or 
technicalities involved and efficiency. A pasture experiment 
with tuberculosis has been under way, since the early spring 
of 1903. The purpose of this experiment is to determine 
approximately the risk of outdoor infection, when tuberculous 
and non-tuberculous cattle are pastured together. This experi- 
ment involves two phases, the first an actual field trial by 
pasturing some tuberculous cows with two yearling steers 
that were not tuberculous. The second proposes to spread 
cultures of bovine tubercle bacilli over a small plot of grass 
and then keep record of climatic conditions, determine how 
long the grass remains infectious to laboratory animals, and 
possibly later to cattle.
