Benefits of the Moon.

Benefits of the Noon.
The moon ministers to human wants
IN several ways thai are not 80 appar-
emit as its light-giving function although
some Of them are much more import
ant. 1t is by observing the position OF
tile noe with reference to the liked
stars that the navigator determines HIS
longitude. Upon the revolution OF the
moon about the earth Is based a con-
venient division of time, the month,
intermediate between that furnished
by the earth's daily rotation and its
revolution through its orbit. Doubtful
points in ancient chronology have been
frequently settled by means OF the
eclipse of the NOON, the dates of which
conld be accurately determined. The
intervention of the noon in eclipsing
the sun gave astronomers the oppor-
tunities for obtaining their first kn0wl-
edge in regard to the solar envelope.
But the largest effects on human well
fare are produced by the Don through
the agency of the tides. Twice a day
the decomposing organic matter
brought down to the seashore by riv-
ers, Or deposited along the waters
edge by human agency, is swept away
by the tidal wave in its course round
the globe. This sanitary service which
the moon performs Is of inconceivable
value. In many harbors large ships
and heavily loaded RATS aud barges
are moved from the entrance to their
wharves, miles above, by that slow but
powerful tug, the tiood-tlde. An
amount of work is thus done which, If
it had to be provided by artificial means,
would cost for such a port as London
thousands, perhaps millions, OF pounds
yearly.
The beautiful damaskeened surface
exhibited by the Woolwick and Elswick
steel guns, says an exchange, is achlev-
ed by means of a special solution COM
posed Of the following ingredients:
TIVE ounces of tincture of steel, one
ounce nitric acid, n ounce copper
sulphate, one and one-half ounces
spirits Of nitre, n and one-half ounces
spirits of wine and n gallon of water.
This solution is smeared over the parts,
and when dry another coat is put on,
the result being a fine brown color,
which, il not dark enough, is made so
by a repetition of the operation, six
coats being sufficient to make the sur
face black. The acid is then killed by
washing with soda solution and the
whole rubbed with a hard brush of
"fle cardn until smooth, after which it
is rubbed with oily waste. Other solu-
tons for this purpose are in use at
some establishments of high repute,
one of the most important of these con-
sisting of a mixture of n ounce each
of sulphur, tincture of steel, nitric acid
and spirits of nitre, with o~ne-fourth
ounce sulphuric acid, one-half ounce
each Of mercuric chloride and copper
sulphate, and n quart OF water.

NJ. GerJOz has devised an apparatus
10y which an audible and visible signal
is given to the englne-driyer if any
part of the machinery to which The
apparatus is fitted should become unduly
hot, In its simplest form. as applied
to the crank-pin of a steam engine, the
device consists of a small cylinder
fastened TO and projecting from the
crank-pin. and containing a plug of
easily fusible alloy, which is pressed
against the end Of the ~crank-pin by a
perforated piston and spring. The
piston-rod controls by means of a lever
IA catch belonging to the mechanism of
a bell placed over the apparatus. The
gear of the bell, which is actuated by
spring power, is previously wound up
by hand and locked by the catch. If
the crank-pin should heat, the fusible
plug melts, thu allowing the piston to
descend, thereby releasing the catch
and sounding the bell. In addition to
this audible signal a disk hidden under
meath the bell is turned in such a posi-
ton that a bright color is seen through
two holes in the disk of the bells.
ShdrinqS from the oiled wood used
In the manufacture of planes at an
Eastern factory were recently put into
a barrel, and tw~enty-four hours later
were found to be almost on fire, their
temperature being over 30Gc f. Before
E O'Clock the shavings were charred and
smoking a few inches beneath the sur
face. This is a practical demonstration
of spontaneous combustion, and illus
trates how many mysterious and
destructive fires may have originated.
Oiled rags and waste operate IN the
same manner.

reports having made a common snail
carry a load of two and a quarter
ounces up a perpendicular wall, its own
weight being but a quarter of an ounce.
A snail weighing a third of an ounce
drew a load of seventeen unce On a
horizontal table, and supported four
ounces while crawling on the ceiling,

snail ON its back.
