Rules For TB Testing 
Barn Equipment a Real Utility 
A merican agriculturist has 
. carried many authoritative and in¬ 
teresting articles on that terrible 
scourge of dairy cattle, tuberculosis. 
We feel, however, that there is still 
much haziness among the average 
dairymen as to just what some of the 
terms used in tuberculosis eradication 
work mean, and just how the plan of 
indemnities works. 
“The primary object is to free cattle 
from tuberculosis, thereby improving 
the dairy breeds of cattle; and behind 
this is the demand for a clean and 
wholesome milk supply. That the 
bovine form of tuberculosis may be 
transmitted to the human family is 
conceded, experts having determined 
this by scientific investigation. This 
work is to be looked upon from an 
economic as well as a public health 
point of view, since great losses result 
from the inroads of the disease in the 
herds of the State 
“The principal feature is the applica¬ 
tion of the tuberculin test. There are 
three methods of applying this test— 
this direction. In the beginning dairy- 
men were somewhat reluctant to sub- 
mit their herds to the test, due to a 
lack of knowledge of the benefits to be 
derived. There has been a wide dis¬ 
semination of information on this prob¬ 
lem and the value of the work is now 
more fully realized. At present there 
is practically a unanimity of opinion 
on the part of herd owners in every 
dairy county in favor of the testing 
of herds.” _ 
BARN EQUIPMENT A REAL 
UTILITY 
The idea that barn equipment is 
merely a fanciful addition to fancy 
barns, and that all it does is to make 
the work easier in the barn is erroneous. 
It is not a very difficult matter to show 
that the modern types of equipment 
that have been developed by barn de¬ 
signers mean real profits in farm oper¬ 
ation. 
Take, for instance, the matter of hay¬ 
handling equipment. Nine out of ten 
MILK PRODUCTION PER COW IN DIFFERENT COUNTRIES 
T illS table will be interesting to every dairyman, It is impossible to 
get comparisons for the same years, but they are close enough for 
practical purposes. It is interesting to note that Canada with a much 
colder climate and shorter season has a larger average production per 
cow than does the United Sfates. The table was compiled by the Bureau 
of Animal Industry of the United States Department of Agriculture.

Buy The Best Silo 
on the Easiest Terms 
For more than a quarter century the Harder has 
been the standard silo for Eastern Farmers. The 
earliest Harder Silos are still giving service. The 
new patented Harder-Victor Front is the most 
important silo improvement of recent years. 
Now, you can buy this genuine improved Harder 
Silo on the most liberal terms ever offered to silo 
purchasers. You can meet the payments out of your 
milk checks, making the Harder pay for itself.

the subcutaneous, the intrpdermic, and 
the opthalmic The subcutaneous test 
is a temperature test, and ^he 
tuberculin has been administered, it the 
temperature of the animal rises to a 
certain point, it shows that the con¬ 
dition of the animal is tuberculous. 
In the intradermic test the tuberculin 
is injected at the base of the tail; if 
a lump rises at the point of injection, 
after a given time, this indicates a 
tuberculous condition. In the opthal¬ 
mic test the tuberculin is placed in 
the eye of the animal. If there is an 
exudation from the eye, in a given 
period—or in other words, if the eye 
discharges—it is indicated that the 
animal is infectod with tuberculosis. 
“This tuberculin test is applied once 
and then if the animal on a test twelve 
months later fails to respond m such 
a manner as to indicate a tuberculous 
condition, it is held free from tubercu¬ 
losis; and a herd of animals so tested 
is entitled to be declared accredited 
tuberculosis-free, or what is more com- 
monly known as an ‘Accredited Herd. 
Indemnities 
“The owner receives payment for 
tuberculous cattle after they have been 
tested, condemned, and slaughtered 
under post-mortem by the State and 
Federal departments as follows: 
“Maximum for pure-bred cattle, 
$112.50 by the State; $50 by the Fed¬ 
eral Government. Maximum for grade 
cattle, $67.50 by the State; $25 by the 
Federal Government. 
“In no case, however, can the owner 
receive more for an animal than the 
appraised value. , 
“In this work there is cooperation 
between the Federal Governpient and 
forty-five States. Its importance is 
shown by the. action which has taken 
place in towns where'ordinances have 
been passed which provide that only 
milk may be sold which cqmes from 
tuberculin tested cows. _ 
“The work was started m New York 
State by the Department of Farms 
and Markets in 1919, in cooperation 
with the Federal Bureau of Animal 
Industry at Washington. Prior to this 
time little progress had been made m 
barns built in these days are equipped 
with hay-carrier track which extends 
the entire length of the ridge. By its 
use, huge slings and forks full of hay 
are brought up into the mow, with very 
little manual labor required in mowing 
■ the hay away. Whereas in times gone 
gone by it would be a good half hour’s 
job to get a load of hay into the far 
corners of the mow, now three or four 
minutes is all that is necessary, and it 
is accomplished with a tremendous sav 
ing of hard labor. 
Another very economical item of 
equipment is the feed and litter carrier 
track which is used in transferring cars 
containing silage, corn, feed, and other 
feed supplies to the mangers, and simi¬ 
lar cars for the removal of the manure. 
These are essential in every modern 
barn, and not only save time and labor, 
but help in the sanitation of the 
building. . . 
Good mangers and stanchions in dairy 
barns, not only make the barn more 
sanitary, but they are more comfortable. 
They keep food clean, prevent it from 
being wasted, and simplify the care of 
the barn. Old-fashioned wood stanch¬ 
ions are entirely out of style, and the 
modern dairyman will not use them. 
Automatic watering bowls are a great 
convenience for the dairyman and a 
great comfort for the cows. When water 
is supplied to the cows in this manner, 
milk production is increased and pro¬ 
duced more economically. This does not 
mean that there is more water in the 
milk-, but it does mean that the cows 
produce more milk on the same feed.—
