This intolerable nuisance and disturber
of individual and domestic peace, is not.
we admit, very inviting subject for any
further acquaintance than we are obliged
to form with II: but nasmuch as a con.
siderable familiarity is forced on us, it
may by worth while 10 know more about
it. The following account is from Cham
ber's Journal.
Very much may be done toward keep.
ing clear of flies, by having the yards,
pg-styes, and haunts for the farm stock
at some distance from the house; and
still more, by keeping a goody number
of fouls, who during the summer destroy
immense numbers Of their Larvae.
There are fifty, perhaps hundred,
different sorts Of flies and gnats, which
annually visit our apartments, and estab-
lish themselves as regular domesiics.
Amongst the most familiar of these are
the green-boule, the blue-boule, or flesh
fly, the larer-ny, impaienty bouncing
against the windows, the biting house-Ay,
which interrupts our reveries by its I'M
welcome at,acAs on the legs and ankles,
and the lesser and larger house flies.

nituve. All Of them are unpleasant COM
panions-tickling, teazing, devouring;
the most. unccremonious visiturs-paying
respect neither TO time, place, nor per-
son.
Their economy and transformation be.
ing similar, the domestic fly may be Ia
ken as The type of the whole. Like most
insects II lays eggs, which are deposited
in hot and moist dunghills, and among
other purefying refuse. These eggs are
Matched into minute maggots Of dirty
white and yellow color, which feed ill
they arrive at about twice the size Of
caraway seed, and in this state they ,um-
BILE hilher and thilher, without any dis
tjnct order of locomoiion. When fat and
fall fed, the maggots lie dormant few
hours, during which time the skin har-
dens, and becomes an oval cylindrical
case, Of chesnu! color; and in this res.
pect the two-winged flies (dipiera) differ
from all the other orders Of insects, which
cast their skins when they become chrys-
Aids. In the chrysals state they remain
from few days to as many weeks, ac-
cording to the temperature many Of them
no doubt, sleeping Throughout winter. Du-
ring this period Of rcp0se, the recent mag
got is undergoing a wonderful trans(orma-
ton within its own skin, which Ultimate
y opens at one end by little circular
lid, and out crccps the housc-hy, with its
body and six legs as large as at any SUBJ
scqucnt period of its life: indeed the alb.
domen is often larger, as it is filed with
fluid necessary TO the expansion of the
wings. When the fly issues from the
chrysalis, the only part which has TO grow

two little crumpled moist objects on each
side of the body. The first &C, of the in
sect therefore is, before they dry, to crawl
up some object, when the fluid in the alb
domcn graviates, or is forced into tho
nervures Of the wings, and expands tie
wrinkles; at last these APPENDICES are
stretched out, and covered with a delicate
transparent membrane, and then the lh,lo
animal is ready for flight.
