A MIXTURE of peroxide of manganese

piled to cooking stoves when they are red
hot, as it is said to make good backing,
not as liable to burn off as common black
lead.

boiling water.
THE average yield of corn-cobs is 7.62
parts of carbonate of potash in ], 600 parts
of the cobs, which is nearly twice as much
as is furnished by the best specimens of
wood. The corn crop, of this country will
supply IL, 400, 000, 600 pounds of cobs,
from which 115, 500, 600 pounds OF potash
might be made.-Sesentyfc american.
THE Connecticut tobacco crops matur-
ing earlier than usual this season, owing
partly to the good growing weather and
partly to the fact that many growers put
out their plants somewhat in advance of
the usual time. The crop, in most in
stances, is of uncommonly large growth,
many fields being utterly impossible. In
many instances growers have to add to
their buildings in order to accommodate
the unexpected crop since the rains.
Probably East Hartford and adjoining
towns will put larger stock upon the
market this season than they have before
for ten years.
the effect OF ebony to walnut, apple, or
pear wood, especially when free from

grammes of nut-galf, 100 grammes of

with suitable quantity of water. This

Afterward, two or three layers of the fol-
lowing preparation are to be applied:
One hundred gramnes iron filings dis
solved in seventy five centiliters of acetic
acid. Each application is to be allowed
to dry before, another is made.
IT is ascertained that saving equal to
as much as 80 per cent. is made by sup
pressing the ,sifted coal and charcoal, en-
ployed with green sand for small iron
castings of the smooth and brilliant sort,
simply by careful mixture of one part of
tar with twenty parts of green sand the
flashing by means of tar or resin is also
suppressed by the same means. Castings
produced from molds with a mixture of
this description are said to be smooth and
bright, as the tar prevents the difficulty SO
much experienced in this kind of pFoduc-
ton, namely: the metal adhering to the
sand and the formation of blisters. Such
a mixture is also found to aid greatly in
the production of castings OF large size, as
the tar tends to absorb the humidity of the
sand. ar
IT appears as the result of some interest
ing experiments recently made that while
a bar of ordinary bronze was utterly in
capable of bearing strain amounting to
ten tons to the square inch a bar of phos-
phor- bronze bore this strain applied as
tensile more than 40O, 900 times before CIV
ing way. A second bar of the same phOs-
phor.bronze actually withstood lat $3.50
applications of load of twelve and one
half tons to the square inch without tract
ure. This article has now come into ex-
teRsive use in Europe for the great bear
ings of the plates in general rolling mills,
and for conical gearing in universal rolling
mills 1t has also been applied with great
advantage not only in the making of pin
ions, but in the driving axles of mills, in
the latter case the superiority seeming to
depend not on the hardness, but on the
great resistance, the arbors in the phosphor-
bronze twisting much less than forged
iron, and not breaking like cast IRON
