with 438.114 reactors. Sc"
The initial infection was little
under Is per cent. The infection
in all herds now being tested,
counting retests, is about SIS per
cent. 1t is believed that it will be
possible to conduct, in 1936-37,
over 100000 tests, with be-
tween $4,000 and 100000 reac-
tors. This work has cost, in fed
eral funds, approximately $685.
0OO. 900 to July l. There are fed
eral funds available to carry on
this work, for the fiscal year July
1936-37, amounting to little
over S19,000,000. In addition,
Virginia has appropriated sgt 900
a year. which will be divided at
the end of the fiscal year 1867
between the owners of all reac-
tors for that period. Maine, New
Hampshire and Rhode Island are
also paying state indemnities in
addition to the federal indemnity
of $25 on grades and $50 on pure
breds. "A bin for state indemnity

legislature by a narrow margin.
WORK IN NORTH CAROLINA
There are NOW under supervi-
sion in North Carolina 46,744 an
imals, and $3.50 reactions have
been removed. There have been
applied, in all, 150,165 tests in
8,0S3 herds, and there have been
as many as IA tests applied under
the federal program on one herd.
Initial tests have been applied on
1920 herds on 50,238 cattle. On
the first test, the infection was
8.95. On the second test which
was of only infected herds, the
infection was 5.88. On the third
test it was 4.49, on the fourth
2.37, on the fifth LEO, on the
sixth 2.17, on the seventh 1.59,
on the eighth 2.45, on the ninth
70, and on the eleventh, twelfth;
thirteenth, and fourteenth, there
were no reactors. Only 337 herds
of the 1920 initial tested were
tested the fifth time, or 8 per
cent of the original herds tested.
FREED OF INFECTION
1t appears that 90 per cent of
the herds were freed of infection
by four tests, and there were no
reactors remaining in any herds
after the tenth test. This work in
North Carolina has cost in claims
to July 1, 1886, $207,7S8.39, and
the operating expenses have been
S25,906.56. The work did not get
we'll under way until October,
1884, as the veterinary forces
were busy in the late summer of
1884 testing relief cattle.
The majority of the work has
been done around large cities and
towns which require a Bangs free
supply of raw milk. 1t is believed
that area work would be the most
economical way of carrying on the
work from now on, and it is
hoped that the coming legislature
will enact an area law. .. ,
: The control of Bangs disease in
the South Atlantic states, where
calving cows can easily and eco
nomicaly be kept separately dur
ing at least nine months of the
year, is not as difficult as it is in
the North. Recently the Bureau of
Animal Industry has ruled that all
herds will be tested under the fed
eral contract until they are eligi-;
BILE for state generalization.
The owner who cleans up his
herd will find that (1) the pro-
duction of milk in clean herd
will be much more economical
than in an infected herd; (2) he
will not have the continual prob
lem of replacement in the fall in
as large a degree as he has in an
infected herd; (3) he will be able
to have a much more regular flow
of milk in a clean herd than he
will in an infected hero, where
sterility and shy breeding are ham
dicaps for regulating production;
and (4) if he has any surplus
stock they will sell, at a1consider-
T, able advance.
It is believed that the advan-
tage of clean herd over a mega
tive herd will pay for the expense
and trouble of cleaning up, every
three years without any additional
indemnity from. the government.
If anyone desires to raise pure
bred cattle, the premium that cat
tie from clean herds bring over
negative cattle once tested is
much larger than is generally real
lied, Last year the. Herriek-Mer-
ryman Sales company sold $50
registered Guernsey cattle at auc-
ton. Of these, 800 were from
state-accredited Bangs free herds
and averaged $4,000, while 324
animals which were negative in
all dilutions, but which were rot
from state-accredited herds, aver
aged $211.66. think a nropor-
tionate difference in value will be
