e herds were not
selected because they were supposed to be tuberculous, but represent the
general cattle stock of the country. These animals included at least 470
head of Shorthorns, of which 170, or 34 per cent, were tuberculous.

To these facts may be added the evidence of Prof. Bang that in the first
half of the nineteenth century tuberculosis was brought to Denmark by
cattle from Switzerland, Schleswig, and England, and that the same thing is
now going on in Sweden and Norway, particularly through English cattle.
Also the evidence of M. Sivori, chief of section at the ministry of
agriculture, Argentina, who has investigated tuberculosis in that country
and who says that "30 or 40 years ago tuberculosis was unknown in Argentine
cattle, and it is still unknown among the native (criollo) cattle. Its
appearance dates from the introduction of pure breeding animals. Statistics
prove that tuberculosis is observed among the grades--above all among those
of the Durham and less among the Hereford."

Moreover, the reports of the royal commission of Victoria, Australia, and
of the New Zealand department of agriculture show a large proportion of
tuberculous cattle in those colonies, where the disease was almost
certainly carried by British cattle.

In the same manner that tuberculosis has been carried from Great Britain to
Denmark, Sweden, Norway, Argentina, and Australia, it has also been taken
to Canada. In one herd of imported cattle slaughtered in the Canadian
quarantine station, 13 of the 14 animals were found tuberculous. One of the
largest Shorthorn herds in Canada was some time ago tested because an
animal from it was condemned when offered for shipment to the United
States. This herd was found to be very badly affected, and an effort is
being made to eradicate the disease by the Bang method. A Canadian official
publication says of another Shorthorn herd, which at one time had a very
high reputation, that when an investigation in regard to tuberculosis was
recently made the disease was found among ordinary cattle wherever animals
from this herd had been introduced, and that this herd, which had been
looked upon as one of the greatest benefits to the farming community, was
really a danger, because it disseminated tuberculosis among the farmers'
herds. Still another well-known herd recently attracted attention because
four animals from it offered for export to the United States were all
tuberculous.
