in livestock raising was shown repeat
edly at the conference Of state and
federal sanitary officials who assem-
bled in Chicago to discuss tubercu-
losis eradication.
Whereas in the past the unwilling.
ness Of cattle owners to have their
herds tested in order to locate the
disease has been q limiting factor in
the work, now there are waiting lists
and the problem confronting state and
federal officials is to meet the de.
