Vermont by Noah Greasy, M. D.:
BOTS are grubs Matched from the
eggs OF the bot fly. This fly is most
active and troublesome in the hottest
weather. In cold, weather it is dor
mant or nearly so. They lay their
eggs on The legs Ct the horse, from
whence they are taken into the stom-
ach, where they hatch into grubs,
and in this state are known as bots;
they attach themselves to the walls OF
the stomach and draw their nutrition
from that furnished the animal and
from the juices Of the stomach. They
cause some irritation, but are
not generally very troublesome. Al
ter time they fall off from the walls
of the stomach and pass otfln the ma
nure, from which they emerge in the
form of fly, and again 50 through
the same round.
"Bots may generally be expelled by
giving the horse sweetened milk,
which the grubs like, and will let goI
their hold to take it the better. An
active cathartic will then bring them
away.
Another form of bot is found in
the head Of the sheep, where they are
called grub in-,he head. These come
from an egg laid in the nose of the
sheep, where they are Matched and
work their way up the nasal passages
and in rams they are often found III
the horns, but they never work out
of these sinuses into the brain, and
the lecturer did not think they ever
caused death in sheep otherwise I'M
good condition.
Another parasite found in the
brain, and mistaken for the grub-ln
the head, is the hydatid, coming from
tape.worm which is taken into the
stomach and finds its way through
the circulation to the brain, produce
ing gid in the head. No cure is
known except cutting through the
skull and taking out the grub with a
crooked wire"
CLASSIFYING EGGs.-The millions
of eggs sent weekly to the Paris mar
ket are classified according to size
and quality previous to their expos
ure for sale. The first point is de
termined by their passage or non-pas-
sage through rings of known diameter,
and their comparative freshness is e8-
timated by mirage" or subsection to
reflected light thrown out by power
full lamps. The difference between
an absolutely fresh and a decidedly
stale egg is readily settled by this test
but the intermediate distinctions are
less easily noted. For tits purpose
the application of the brine test is
recommended, the fact being well
known that if eggs Of different ages
are put into a strong solution of salt
they sink more or less deeply in the
liquid according as they are fresh or
stale. There is, however, an obvious
source of fallacy in this method, If
roughly applied, since an egg that
would pass muster as tolerably fresh
when immersed in a weak solution,
would rise to the surface as a down
right bad one in stronger brine.
The difficulty could be partly met
bv the invariable use Of a standard
solution of known strength, and such
a one is now recommended by a Dion
chemist who has paid much attention
to the subject. The proportions he
advises are 81 on. Of table salt in a
quart Of pure water. Placed IN
brine of this strength, an egg just laid
will exactly touch the bottom of the
vessel; if twenty-four hours old, it
does not quite reach it; if three days
old, it floats midway in the liquid;
and if more than five, it rises to the
top. Beyond this age, the shell rises
above the surface Of the fluid, pro-
truding further and further, within
certain limits, from day to day.-R~-

The best time time to kill weed
is as soon as it is born, before you can
see it. When the seed has germlna-
ted, and is Just ready to break through
the ground, then the least disturb
auce of the soil disarranges its con-
nections and it dies in the hot sun
but if it grows until it makes roots, if
it is disturbed considerable you do not
kill it; it has hold upon the soil and
