plates are found to be almost inc estruc-
tible. They not only can be printed
from an almost unlimited number Of
times, but they are better calculated
than those ofcopper to withstand those
inevitable accidents constantly occur
ing in printing establishments. Prinr-
ters are sometimes obliged to set aside
as useless their best plates, which are
often damaged by a grain of sand or
by chance knot in the paper. These
accidents not only involve the expense
of renewing the plates, but sometimes
occasion Interruptions and delays in
works of very pressing nature. These
are some among the many advantages
which may be expected to accrue from
the introduction of iron electrotypes." :"
Inproved Form Of Boiler.
A new sectional boiler, noticed in the
English papers, is believed to possess some
important advantages over similar con-
structions. It is made with the tubes bent
into the shape of worm, OF partially 80,
the pitch or amount of bend aryine with
tho diameter ofcircles of holes in tho tube.
sheet and the heigh: Of tho boiler, except.
ing only in tho centre tube, which, being
from four to ten inches in diameter, &C.
cordjng to power Of boiler, is eth aight,
with faneed ends, riveted in the usual
manner to the top and bottom tube sheets.
This centre tube 10 supplied with drop
ping plug or damper, fluted round the
sides. The use of the plug.damper is this !:
When the fire is lighted, the water being
cold in the boiler, it is raised fully to
establish draught, and prevent the con
densation Of the prodacts of imperfect
combustion, in the shape of SCOT in the
smaller tubes; when the fire is we'll under
way, the plug is allowed to drop ON its
seat on the top of the centre tube, tho
flutes or notches around its side allo ing
certain amount of draught to render the
inside surface Of tho tube useful as heating
surface.
The advantages claimed fer these spiral
tubes over tho ordinary straight upright
ones, are that they prevent the leaking Of
tho tubes-a constantly recurring trouble
iu upright boilers their spring. ike form,
permitting easy expansion and contraction,
without affecting their tightness in the
tube sheets; they permit, too, the use Of
the convex lower tube sheet, or furnace
crowns, thus tending to prevent tho plate
from cracking through deposition Of slit,
etc., they also incr" "ase largely the heating
surface by having much larger tube in
the same height Of boiler. The beating
surface is likewise ofa more effective de.

much a. possible, the best Of oil beating
surface, the horizontal tube, excepting in
the steam way, or part of tube above the
water line, which is straight and con-

Tea Culture in Florida.
It may not be generally known, but
the fact is none the less patent, that
the genuine tea.plant is growing pro-
fusely all over the suburbs of the city,
and presents quite thriving appear
ance wherever it is found. We are
informed by a prominent mechanic Of
this city, and an old resident at that,
that he uses no other tea in his family.
He plucks and dries what he requires
for his own use and says it is equal to
any black tea offered for sale at the
grocery stores. If some shrewd New
Englander were only here he would
soon make regular business of pre-.
pairing tea crop, and he would make
money by the operation. The leaves
can be dried in the shade, and will
curl of themselves naturally in the pro
cess of drying. The crop would cost
nothing but the trouble of plucking it,
and a wagon.load could be picked in q
hour without half trying. Ii some OF
that kind of people who are always
grumbling about having nothing to dc
would try the experiment of preparing
this tea for market, We think they
would find it to be u lucrative business
and one, too, that they would pursue
with avidity rs soon as they found how
readily they could dispose of all they
had mahufactured.-Jacksonville Ua
