12 Commission Report: Tuberculosis. 
uniform ; that the laws of the United States and Canada and other 
American countries for the admission into America of animals 
from without be made stringent and as much alike as possible; 
and that the laws governing the interstate and inter-provincial 
movement of cattle and that between different American countries 
be harmonized. 
The laws governing inter-state and inter-provincial movement 
of cattle should be of such character that every state and every 
province will be free in its eradication work from unnecessary 
difficulties due to the existence of the disease in other states and 
provinces. 
Legislation is especially required to prevent the various frauds 
which interfere with the satisfactory use of tuberculin as a diag- 
nostic agent for tuberculosis, as well as for official supervision 
over all tuberculin sold to be used by veterinarians and others. 
RESOLUTION 12. SANITATION. 
In the eradication of tuberculosis it should be kept in mind 
that, in addition to protecting animals against exposure to tubercle 
bacilli, it is desirable to make them as resistant to infection as 
possible. This can be done by stabling them in clean disinfected 
and properly ventilated and lighted barns, giving them abundant 
clean water and nutritious food, a sufficient amount of daily 
exercise in the open air, and attending generally to those condi- 
tions which are well known to contribute to the health of animals. 
The daily removal of manure from stables, and water tight 
floors and good drainage in stables are urgently recommended. 
Young stock particularly should be raised as hardy as possible 
and should be accustomed to liberal exercise and living in the 
open. 
RESOLUTION 13. IMMUNIZATION. 
That as none of the various methods for the immunization of 
animals against tuberculosis have passed sufficiently. beyond the 
experimental stage the Commission is unable to endor 
se any of 
these for practical use at the present time.
