PROFESSOR WALLEY. 
calved, are sent long railway journeys to the city, jostled and 
tumbled about in railway trucks, exposed to the effects of 
cold, hunger and fatigue; they are put into our byres and 
washed from head to foot, then allowed to dry as best they 
may, and exposed the following day to the effects of incle¬ 
ment weather, and with this they are gorged with succulent 
food for the purpose of increasing the flow of milk, and in the 
vast majority of cases the lacteal secretion is allowed to accu¬ 
mulate to an inordinate degree, thereby inducing, with the 
other influences mentioned, a febrile condition, which fre¬ 
quently masks any evidence that may be present of the exis¬ 
tence of disease of an important character. 
So far as the spreading of disease by the dairy cows of 
the city is concerned, I am in a position to say that the dan¬ 
ger in this direction is infinitesimal, as there is not one animal 
in one thousand sent out of our byres for any other purpose 
than for slaughter, and the vast majority of these cows never 
come in contact with store animals after they leave the byres; 
they are sent direct to the fat stock marts, on fat stock sale 
days, and are drafted thence to the various fat stock centers 
for immediate slaughter. The only danger that arises within 
the city is the returning to the market of animals which have 
been purchased on previous days of sale and found to be 
amiss after coming into the hands of the purchaser. Even 
this danger is guarded against as carefully as is possible. 
Experimenting with Pleuro-pneumonia. 
I have already remarked that a certain proportion of those 
who have written on this subject have advocated the adopt¬ 
ion of experimentation on a limited scale with the view of 
clearing up doubtful points as to the nature of the malady 
and its cause. Now, Mr. President and gentlemen, 1 would 
ask you—of what value can limited experimentation be in this 
country, seeing that unlimited experimentation has been car¬ 
ried on in various continental countries for many years past, 
and seeing that much study has been devoted to the subject 
by men of far greater experience and with far greater oppor¬ 
tunities than are possessed by any past or prospective experi-
