Mg DeLaval is milking mg com 
than theg were ever milked kg hand 
So says a prominent Holstein breeder 
who is always careful about his milk¬ 
ing. This is not an exceptional in¬ 
stance, in view of the evidence that is 
coming from De Laval Milker users, 
such as the following: 
.—“After using the De Laval Milker 
on our herd of forty cows 
we find that the cows 
respond freely to the 
machine. We believe 
this is due to its uniform 
action.” 
—“The action of the 
De Laval Teat-Cup is en¬ 
tirely different from all 
other makes of machines. 
It is mild and pleasing to the cow, 
causing her to respond quickly.” 
—“I can milk in just half the time 
with the De Laval, for my cows give 
down their milk better, and now in-

stead of sitting in a barn and milking 
23 cows by hand, I can just watch the 
work being done and it is a pleasure.” 
—“I say that the De Laval Milker 
will absolutely get more milk over 
hand milking and save so much time 
that it will pay for itself in a short 
time.” 
And in this manner we 
could go on quoting from 
among the thousands 
of other satisfied users, 
proving the claims made 
for the De Laval Milker 
—that it 
1. Increases milk pro¬ 
duction; 
2. Saves time and labor; 
3. Produces cleaner milk; 
4. Makes dairying more pleasant; 
5. Makes more money.

Tuberculin Testing 
We had tuberculin testers Yvith us last 
Spring. The results of tests gave rise 
to much talk and conflicting opinion. I 
wrote to Department of Agriculture at 
Washington, D. C., for cow book. The 
government, testing 7,781,030, found tu¬ 
berculosis in less than 1 per cent; to be 
exact, 0.98. Iowa test shows 6.3, or one 
out of 15. Which test is right? The 
government sees the dressed meat hung 
up, to be seen in all its parts; the test as 
applied by the veterinarian is by injecting 
a test on the live animal. Of all domes¬ 
tic animals, I have heard many times, 
cattle are the healthiest. Now I am told 
that 16 out of 100 are sick with one dis¬ 
ease alone. To be compelled to sacrifice 
15 good cattle and get scarcely anything 
for them is not right. B. D. 
Iowa. 
The importance of having all cattle 
tested with tuberculin and the reactorS 
condemned, slaughtered and examined by 
veterinary inspectors is that without such 
testing no one can be sure that his ani¬ 
mals are not affected. It is easy to de¬ 
tect something seriously wrong when a 
cow becomes thin, weak, and coughs, but 
those symptoms only occur in the ad¬ 
vanced stage of pulmonary tuberculosis, 
while the disease may be present in an 
incipient form in many cattle in the 
same herd. .When that is the case the 
milk is dangerous for use by man or ani¬ 
mals, and the disease gradually spreads, 
being contagious, until all of the herd 
members are affected. Deaths then occur 
at intervals, and all seriously affected 
cows prove thriftless and unprofitable. 
In many a herd every animal has been 
found affected when tested. Subsequent 
tests showed no reactors, if sound cattle 
are placed in the stables after they have 
been thoroughly cleansed, disinfected and 
whitewashed. 
The testing should be done twice a year 
in all herds, and every possible precau¬ 
tion taken to keep out the infection. 
Whole counties, in some States, have been 
freed of tuberculous cattle, and the at¬ 
tempt is being made to keep them free. 
That is accomplished by the area test 
plan, conducted by the Federal and State 
authorities, and a fair rate of remunera¬ 
tion is allowed the owner for his con¬ 
demned cattle that are found so affected 
that the meat lias to be prohibited from 
sale. It is just as important to detect 
and remove one affected animal in a herd 
as 15, for the one beast will in time af¬ 
fect the lot, and it is better to get rid of 
it at once and prevent the 14 from becom¬ 
ing similarly infected. 
The area test plan can only succeed if 
every citizen gives his hearty support to 
the authorities who conduct the test. 
That is being done in many localities, and 
those that get rid of the disease first and 
stay free from it will reap a wonderful 
benefit in discriminating sales of pure¬ 
bred “T. B. free” animals and their pro¬ 
ducts. The serious matter now confront¬ 
ing all interested in stamping out tuber¬ 
culosis is the terrible prevalence of the 
disease in swine. That condition exists 
even where bovine tuberculosis has been 
stamped out, and it lias been found that 
the avian tuberculosis of poultry is to 
blame for the prevalence, as their form of 
the disease is communicable to hogs. The 
pasteurization of creamery and cheese 
factory by-products, before feeding them 
to hogs, is also necessary. Affected poul¬ 
try must be destroyed. All infected prem¬ 
ises must be made sanitary. 
Thrush and Canker of the 
Sole 
I have a horse about 18 years of age. 
His front feet are going bad. I had a 
doctor look at them and he says it is 
“cancer” of the foot and that it cannot 
be cured. As the horse is a very good one 
I do not like to destroy him before get- 
ing advice from you. The hoofs have a 
very strong smell and have got very wide ; 
have been sore for nearly a year. c. E. 
Pennsylvania. 
We think it likely that the veterinarian 
called the disease of the hoof “canker,” 
and not cancer. That certainly is a very 
troublesome disease to cure, hut it is cur¬ 
able in some cases, if not gone too far. 
Canker starts with thrush, which is the 
term applied to that condition of the frog
