II Is no uncommon sight In New York
to see laborers rubbing down the fronts
and steps Of ireest0ne buildings with
sand and water to takeof stains and give
them n fresh aud new appearance. In
London they have recently for this pur-
pose adopted the use of steam fire en-
gines. The Jet OF water Is projected with
such force, IL Is said, as To remove the
diseoloration as efiectually from the stone
as by hand aud sand, aud at a fraction of
the cost. 0n Portland stone 1t Is said to
be specially adapted, and II so, we do not
see why IL cannot be used on marble

Winkler has found that the best iron
cement can be made by preparing a mix
ture of IL parts Of clean wrought iron
filings, two parts of pulverized sal am
moniac, and two parts of flowers of sui
phur. This mixture can be kept in dry
p .cksge any length of time, unchanged,
kand when required for use, 1t is better to
reduce one part of 1t with twelve parts of
iron filings, and enough water contain
ing little of sulphuric acid, to form a
stiff paste. When thus reduced 1t must

Gun cotton Is now manufactured In
England to an amount exceeding 100
tons per annum. The cotton fiber Is re-
duced to pulp, as In paper making, In
which condition the excess of acids is
readily removed. The pulp Is com
pressed into disks, under a pressure OF
Is tons to the inch, and then dried. These
disks are inch to inches in diameter,
and IL inch TO 2 inches thick. In the
open AIR this compressed cotton burns
intensely, but without explosion; but
when properly exploded under close
confinement, Its strength is from two to
five times that OF the same weight of gun.
powder. If accidentally wetted, this form
of gun cotton can be redried by exposure
to the sun, or even by gentle heat
without risk ofexplosion or deterioration
