gate, study and report on all practical problems and questions 
relating to the breeding, maintenance and utilization of animals 
with a view to fostering and placing animal husbandry, in all 
its phases, upon a more scientific, economic and profitable basis 
in that State. This important branch of veterinary science has 
been left almost entirely to the layman to manage the best he

Dr. D. E. Salmon, Chief of the Bureau of Animal Industry, 
has been engaged in a lively discussion upon the subject of the 
tuberculin test with Hon. John Dryden in recent numbers of 
the Breeder's Gazette. Unfortunately this usually sound stock 
paper entertains some very dangerous views upon the subject of 
tuberculosis, the dissemination of which will render the sys¬ 
tematic control of the disease by the Government more difficult, 
since it greatly underestimates the contagious character of the 
malady. A campaign cf education, carried on through farmers’ 
institutes and the public press, is the surest method of placing 
the subject before stockmen in its true light.

appear differently according to the position from which they are 
seen, and it is only by observing an object from every possible 
point of view that we can secure a perfect impression of it, and
