finding SO per cent Of the milk cow!
and 40 per cent of the young cattl'
and calves diseased.
He made a solid boar partition II
the stable and completely separated
the healthy animals from those tina

The claves of the diseased mother:
We're removed Immediately after brit
from the infected stable and after hav
ing the raw milk OF their mothers the
first day were always afterward giveI

This plan was Followed year afte1

defective. the farmer did not promptly
remove the highly tuberculosis am
mails and some infection of the health.

tests.
But. in spite Of these drawba> a>ks, tn
healthy division increased year by veal
and the task Of cleaning up the her'
was finally completed by selling tlt
rest OF the reacating animals. about -
head.
The superior milk from this farm
is now sold in Copenhagen as mill
for infants" and IL the test of las
year not one Of the 2o8 animals re
acted.
DR. Bang says it was soon demon
strated that the principle of keepinE
the calves and healthy cattle away
from infection was correct and that
wherever carried out carefully his
method has shown that n healthy hero
can easily be raised from the calve:
OF diseased mothers.
He wants the badly infected animals
killed a. once but would keep those

snow progress Of the disease and raise
their calves in healthy quarters or
milk protected from infection.
DR.. Pangs method was tried sue

enty-five being here given:
Seventy-fivc owners :;.637 cattle

two-thirds or 2,2i6 reacting.
After the testing and isolation had
been continued for number OF years
the final test applied TO the 5.256 ami

SiXty-six of these demonstrations
We're on small farms having a total OF
.S25 cattle. of WHICH 1,045 reacted
and the last test showed 1886 cattle
in these herds not one Of which was
Infected. These results We're com
puted by DR.. Bang in 1905. No one
could want more complete and strik-
ing proof OF the practical success o1
this simple means OF preventing con
tagion.
The following separate instances eX-
plain the applications of the Ban:
method very clearly: In q Jutlant

(S2 per cent Of the fullgrown ami
nlalS) in 1908 there was just one re
action out of PAS head; entire cost %

In 1886 Count Wedell had 240 cattl,
tested, 166 reacting: in 1903, 264 test

Ahlamann had FL diseased cattle II
1895 80 per cent u all: in 1908 only

duced toto.
E. Tutein. 115 head reaeting il
1895, 70 per cent Of all; last test only
reacting out of 1873.
Tesdorpf in 1893 tested Only hi!
calves and young cattle, 1S3 head

cattle at four farms. while the react

Isolated at separate farms, in 1901, on'
farm had 208, every one healthy; q
the other farm four reacted out o1
1926. In 1907 only 2 animals reacted
out Of 5s3 and the reactnG diVlSior
was reduced to 80 COWS.
Langerman tested IS calves in 1896
finding Is diseased: the testing of the
calves was continued and gradually 9
perfectly healthy herd was bred, mum
bering 1877 this year.
Scavenius tested "a young cattle l.
1895, half reacting; in 1907 only
diseased cattle oct of 443 and q. re

The total expense Of this isolation
on one small farm where the cattle
were badly diseased was only $54 anC
in some instances the cost was still
less.
