900, to February 19, 1901, the period that the
department inspector tested all Canadian cattle intended for shipment to
the United States, 140 purebred Shorthorns and 3 Shorthorn grades were
tested, and of the total number 26, or 18 per cent, reacted. During the
first month that this inspection was enforced, and when it may be assumed
that the condition of the cattle most nearly represented what it had
previously been, 74 cattle were offered for importation, and 18, or 24.3
per cent, were found tuberculous.

In justice to Shorthorn cattle it should be said in this connection that
they are probably no more susceptible to tuberculosis than are other
breeds, but the disease has been allowed to spread in certain herds and
families to such an extent as to give a wrong impression concerning the
breed as a whole.

The slaughterhouse statistics of Prussia show 14.6 per cent of the cattle
and 2.14 per cent of the hogs to be tuberculous. In Saxony the percentage
is 29.13 with cattle and 3.10 with hogs. In the city of Leipzig the figures
are 36.4 for cattle and 2.17 for hogs. (Siedamgrotzky.) Of 20,850 animals
in Belgium tested with tuberculin in 1896, 48.88 per cent reacted.
(Stubbe.) Of 25,439 tested in Denmark from 1893 to 1895, 49.3 per cent
reacted; and of 67,263 tested from 1896 to 1898, 32.8 per cent reacted.

Figures available in the United States allow us to make a reliable estimate
of the extent of tuberculosis of cattle. The following summary is
presented:
