The same factors which have made 
the De Laval Separator famous are 
back of the DE LAVAL MILKER 
Just as the De Laval Cream Separator established new 
and higher standards of efficiency and construction, so is the 
De Laval Milker establishing higher standards amongmilkers. 
It is strong; durable; simple in construction and operation; 
easy to keep clean; saves time, and increases production. 
The same policies which have made the De Laval 
Cream Separator the most popular and most widely 
used in the world are back of the De Laval Milker 
and are responsible for its rapidly increasing use. 
Long ago the De Laval Company recognized the 
need for a mechanical means of milking, to place 
the dairy business on a machine basis. For over 
twenty years experiments have been 
conducted, and after many years of 
research, test and use, and not until the 
De Laval Company was absolutely sure 
its milker was actually a better way. of 
milking, was it offered for sale. Now 
after four years of commercial use, in 
all sections of the country, owners are 
proving that it not only saves time and 
eliminates the drudgery of milking, but 
it actually increases the flow of milk 
even over good hand milking. 
Service also helped make the De Laval 
Separator famous; and it is service back 
of the De Laval Milker that is helping 
to create preference for it among dairymen. This 
means that the De Laval Milker will be properly 
installed, that you will be thoroughly instructed in 
its care and operation, and that the De Laval Com¬ 
pany’s interest in you, instead of ending there, 
just begins. 
The De Laval Separator has rendered a service 
of inestimable value to the dairy industry 
—the De Laval Milker is doing the 
same. It removes the one great draw¬ 
back to dairying—hand milking. Ameri¬ 
can farmers realize the service, stability 
and integrity back of the name 
“De Laval,” all of which is reflected 
in the rapidly increasing use of De Laval 
Milkers.

AILING ANIMALS 
Answered by Dr. A. S. Alexander 
Mammitis 
T noticed in a recent issue of your 
paper, a description of udder trouble 
diagnosed as mammitis,' or garget and 
giving treatment, f have a cow with 
apparently the same trouble, of several 
weeks’ standing. One side is about dry, 
other side has been milked right along. 
Several days ago a heifer freshened, 
standing by side of affected cow and 
seems to have same trouble. One teat 
gives practically no milk, there is a lump 
right above teat. Other teats are milk¬ 
ing all right, about eight quarts a day. 
Is it likely to spread to the other cows 
and what can T do to prevent it ? 
New York. G. F. S. 
We invariably advise instantly isolat¬ 
ing a cow whenever anything goes wrong 
with her udder, ns there is grave danger 
of an infection being spread from cow to 
cow by the milker’s hands or teat cups 
of the milking machine. The abnormal 
milk should also he caught in an old pail 
containing a disinfecting solution. If al¬ 
lowed to contaminate floors or ground, 
they, too. may be a source of contagion. 
The heifer in question may, however, 
have had an attack of garget when young 
which led to formation of the lump and 
milkless condition. Such attacks are 
often caused by calves sucking one an¬ 
other’s teats. That should he prevented. 
Attacks are always likely to recur worse 
than before at a subsequent calving and 
perfect recovery is rare. 
Warts 
T have a grade Guernsey heifer between 
two and three years old. due to calve in 
a month. She is afflicted 1 with large 
warts, some of them an inch and a half 
across, probably what are called seed 
warts. In particular she has one on one 
of her teats, large as a small butternut, 
that'is going to cause trouble when she 
freshens. Is there anything T can do 
for her? She is a good animal and I 
want her for a cow. There is no veterin¬ 
arian within ten miles of here 
Connecticut. w. r. >r. 
Snip off with scissors any wart that 
has a slim neck and if it starts growing 
again rub it lighly with a lunar caustic 
pencil. Do that now if the large wart, 
cannot he snipped off. Repeat the appli¬ 
cation every two or three days, removing 
the scab when that is possible. A sat¬ 
urated solution of bicarbonate of soda 
applied fresh twice a day is also good 
for warts on teats. 
Thriftless Cow 
We have a cow eight years old who is 
getting poor eating eight quarts of ground 
coru and oats mixed, and good hay. She 
has good teeth and eats very much. We 
expect that she will calve in July. She 
gives about two quarts of milk. She is a 
registered Guernsey and we would like 
to have a calf from her. A. B. 
Such a cow should he tested with tu¬ 
berculin. unless she was tested inside of 
six months. As she is giving but two 
quarts of milk it would be best to dry 
off the remaining milk flow and feed her 
a light laxative ration of bran and oil- 
meal along with a little silage or roots, 
and- plenty of clover or Alfalfa hay until 
grass is available. If she proves to be 
tuberculous she will have to he disposed 
of in accordance with State law. 
Blood in Milk 
T have a cow that has been giving out 
clots of blood for about two days from 
one teat. The other three seem to he 
all right. There seems to he a hard lump, 
that, when 1 milk her. breaks up and 
comes down in clots of blood, from the 
teat. E. A. P. 
The growth bleeds from irritation at 
milking times. An operation sometimes 
succeeds in such cases and consists in 
the introduction of a special hollow 
cone cutting instrument by means of 
which the growth is scraped off. A grad¬ 
uate veterinarian will know to which in¬ 
strument we refer and will use it with 
every possible precaution against infec¬ 
tion. Meanwhile immerse the teat twice 
daily for five minutes or more in hot 
water containing all the boric acid it 
will dissolve and also swab the inside of 
the duct by means of a new, clean tobacco 
pipe-stem brush dipped in the solution. 
Obstructed Teat 
T have a three-year-old cow. She 
gave milk all Summer and was a fine 
milker. A short time ago there appeared 
in her teat up near the udder a small 
bunch. For two or three days she gave 
very bloody milk and now the hunch is 
larger. It does not seem to he very sore 
but blocks the milk passage so it is al¬ 
most impossible to milk her. G. 1). 
In such a condition the only hope of 
relief would be to have a trained surgeon 
cut through the wall of the teat and 
remove the obstructing growth when the 
cow is dry. That is a formidable and 
somewhat dangerous operation so that it 
usually is best to simply dry off all milk 
secretion in the affected quarter. We 
should advise you to do that when slie 
calves again.
