orubs In Cattle.
Last winter q good many of our
readers wrote to US complaining that
tumor-like punches had appeared
upon the backs Of their cattle and
they were at loss to know what was
the cause. while others on squeezing
the Jumps had found them to contain
large srubs. We explained that these
grubs came from the eggs of the OK.
MARBLE hy. which are deposited under
the skin during dy time In summer.
That time Is at hand, and We are
writing this article to remind our
readers that MARBLES can be prevented
BY attention to the cattle when nies
arc most annoying. When the MARBLE
ny comes along the cattle show every
sign Of terror and often stampede or
run to water. where they stand all day
rather than Craze where dies can
gst At them. It seems that the ny
does not care to cross water and we
presume that this IL true Of some
other insect pests of cattle. Despite
the partial protection given by water
and in all places where ponds can not
be utilized by cattle MARBLES will be
found on the backs Of cattle during
the early months of winter and the
lunches grow rapidly until In spring
they are Of full size and the grub or
maggot escapes. burrows into the
ground, and after q time energies rs a
full fiedged ny to carry on the pestifer-
Gus work Of its kind, writes A. 8.
Alexander In Farmers Review.
When 1t is seen that nies are most
troublesome to cattle on grass we
think 1t will surely pay to spray their
backs with any one Of the commercial
hy repellers. These applications af-
ford but temporary relief, but may be
used two or three times week. and
will then have an appreciable effect
in preventing MARBLE ny attacks. To
the same end 1t 10 well to provide
shade for cattle away from barn yards
and feeding yards where manuie IL al.
why's an attraction to hies. Left to
themselves 1t will be observed that
,csttle get as far away from these
places as possible during fly time.
and seek the shade at distant part
OF the pasture where water Is 70 be
had. A lesson should be learned from
this habit Of cattle and the owner
will do we'll to provide shady place
for his stock away from the farm
yard. In addition to using n7 repell-
era daily or several times . week, II
the. bunch Of cattle IL large 1t has been
found good plan to wash the backs
o! the cattle couple Of times in late
full. using strong brine for the pur-
Pose. This IL supposed to kill the
Young grubs before they have attained
great size and 1t seems to be quite Of.
factive for this purpose. Some SCI
satists claim that the eggs OF the
ox-warble ny are not deposited ON or
under the skin of the backs Of cat
tie, but are laid upon the skin Of the
fore legs and breast. where they may
be easily licked OF by the animal.
From this source the eggs are said to
be taken into the stomach, where
they hatch out and penetrate the
walls Of the stomach or gullet. gain
access to the blood and finally work
their way through the flesh and other
tissues until they arrive under the
skin. We do not take any stock in
this alleged life-history of the ox.war-
BILE hy. We believe that the eggs are
deposited under the skin and there
hatch out into maggots which irri-
tate the surrounding tissues with the
prickles upon their bodies and so give
rise to an indammatory liquid in
which they live and from which they
derive their nourishment. They cause
great suffering to their hosts when
numerous and so retard growth or
fattening, while 1t has been found by
investigation that hides are seriously
damaged for the purposes Of the tan
ner and consumer Of leather to the ex-
tent Of many thousands Of dollars an
nually. 1t is well. then. to allay the
suffering Of the animals as far as pos
sible. and at the same time to prevent
the loss Of flesh or milk certain to
follow the irritation due to numbers
of large grubs under the skin Of tho
backs Of cattle. A solution Of any
one Of the commercial coal tar dips
will prove fairly effective in repelling
MARBLE flies and will last longer II
mixed with oil, tar water or oil OF
tar in the form Of an emulsion. Some
have had fairly good results from kero-
sene emulsion, but thus far NO perfect
ny repeller has been hit upon that
does not contain tar products such
as carbolic acid, creosote. etc.
