Grubs in Cattle.

.." .n.'. SSS 'b #r.fE.. VI
Last winter a 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 a loss to know what was
the cause, while others on squeezing
the Jumps had found them to contain
large grubs. We explained that these
grubs came from the Eggs of the OK
MARBLE fly, which are, deposited under
the skin during fly time in summer.
That time is at hand, and we are
writing this article to remind our
readers that MARBLES a be prevented
by attention to the cattle when flies
are most annoying. When the MARBLE
ny m along the cattle show every
sign of terror and often stampede or
run to water, where they stand all day
rather than Craze where flies can
get at them. 1t seems that the fly
does not care to cross water and we
presume that this is true of some
other insect pests of cattle. Despite
the partial protection given by water
and II 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 OF
maggot escapes, burrows into the
ground, and after a time energies as
full fiedged fly to carry on the pestifer
GUS work Of it's kind, writes A. S
Alexander in Farmers Review.
When it is seen that flies are mos
troublesome to cattle on grass we
think it will surely pay to spray theil
backs with. any one of the commercial
fly reporters. These applications at
ford but temporary relief, but may b.
used two or three times a week, ant
will then have an appreciate efec
in preventing MARBLE fly attacks. TX
the same end it is we'll to provide
shade for cattle away from barn yard:
and feeding yards where manule is al
ways an attraction to flies. Left t.
themselves it will be observed tina
cattle get as far away from thes'
places as possible during fly time
and seek the shade at a distant par
Of the pasture where water is 70 b.
had. A lesson should be learned iron
this habit of cattle and the owne
will do we'll to provide a shady plac
for his stock away from the farm
yard. In addition to using hJ repel.
ers daily OF several times a week,
the bunch Of cattle is large it has bee
found a good plan to wash the back
Of the cattle a couple of times in lat
fall, using a strong brine for the pul
pose. This is supposed to kill tn
young grubs before they have attaine
great size and it seems to be quite e
fective for this purpose. Some sc
entists claim that the eggs of tn
ox-warble fly are not deposited on c
under the skin of the backs of ca
tie, but are laid upon the skin of tn
fore legs and breast, where they ma
be easily licked off by the animal.
From this source the eggs are said
be taken into the stomach, wher
they hatch out and penetrate tn
walls of the stomach or 'gullet, gal

their way through the flesh and othe
tissues until they arrive under tn
skin. We do not take any stock /
this alleged life-history of the ox-wal
BILE fly. We believe that the eggs ar
deposited under the skin and Their
hatch out into maggots which irr
tate the surrounding tissues with tn
prickles upon their bodies and so Civ
rise to an infammatory liquid i
which they live and from which the
derive their nourishment. They caus
great suffering to their hosts whe
numerous and so retard growth, c
f%attening, while it has been found b
investigation that hides are seriousl
damaged for the purposes Of the tai
ner and consumer Of leather to the e.
tent of many thousands of dollars al
nually. 1t is well, then, to allay tn
suffering of the animals as far as po
sible, and at the same time to preve1
the loss of flesh or milk certain t
follow the irritation due to number
of large grubs under the skin of th
backs of cattle. A solution of an
one of the commercial coal tar dir
will prove fairly effective in repellin
MARBLE flies and will last longer
mixed with oil, tar water or oil {
tar in the form of an emulsion. Som
have had fairly good results from kerr
sene emulsion, but thus far no perfet
fly repeller has been hit upon thu
does not contain tar products sue
as carbolic acid, c]reosote. etc.
