Down grade. More than $37, 900, 900
of Massachusetts railroad stock paid no
dividends last year.
THE receipts of the New York city street
railroads, sixteen in number, foot up over
$4,000, 900 for last year.
FOREST PLANTING is thriving in Min
nesota. The st. Paul e. Pacific Railroad
has set out over 4 200, 900 young trees, and
altogether it is estimated that 10000, 600
have been planted on the prairie lands
AN ENGLISH gentleman residing in
Greenbrier County, w. Va, sent a spcci-
men Of what he supposed was firc-proof
limestone from quarry in that county, to
the Centennial rooms in Wheeling, but
upon analysis it was found to be fine mar
bic. There is a vein of excellent varie-
gated marble on the headwatcrs of An
thongs Creek, in Greenbrier County and
Beaver Creek, in Pocahontas County,
which will doubtless, at no distant day,
prove to be of great value. -...
Mr.. WESLEY W. GARY, of Hunting
don, Pa, is the latest discoverer of a new
motor who has been announced. His dis
covery is an article which when placed
between a magnet and substance which
it would naturally attract destroys its at
| tractive powers. He has just secured
patents for his invention. The Hunting
don Journal, which places great conf
dence in the value of the discovery, adds:
"But setting aside the discovery of the
cutoff or interpose, Mr. Gary has accom-
plishcd the utilization of the power Of
permanent magnets Qhereby accomplish
ing The same object by simply changing
the poles of an electro magnet by very
simple device"
A DENTIST Of Philadelphia has invent
ed little machine for putting the filling
| into teeth, which is thus described: A
simple cylinder holds small plunger,
which is fastened TO spiral spring in
side, so that it can move up and down
within the cylinder. At one end of the
cylinder is a piece of insulated iron,
which is turned into magnet by an
electrical current, the attractive force of
which is opposed to the spring. A sim
pie automatic attachment to the plunger
breaks the current AMI releases the mag
net. The result is that the plunger, as
soon as the current is applied, begins to
move back and forth with as great rapid
| ity as the connection of the magnet and
battery can be made and broken. This
| depends somewhat on the distance
through which the plungcr passes. AS
| in this instrument that distance is very
small the machine will deliver several
| hundred blows a minute; indeed, so fast
as almost to produce the impression of Il
continuous pressure. A small battery
works it at Il cost of about twenty cents
a day.
THE latest novelty among adiuncts TO
stoves and fire places consists in the en-
ployment Of bright nickel plated sheet
Of metal, suspended over the fire, and ad-
justcd in proper position by crank, the
rod of which passes through the side Of
the stove or fire place. While the fire is
being kindled, the plate is turned toward
the front to protect it from being smoked,
but when the fire is fairly burning, the
plate is turned back at an angle of forty
five degrees, as indicated by the wheel on
the side of the stove. The result is de-
scribed about as follows: The reflection
from the bright metallic surface produces
the effect of a double fire, and adds great
| ly to its cheerfulness. In addition TO
this, il is claimed that the large amount of
heat thus reflected by the plate is, to
great extent, clear gain, ard that the eff
feet of its employment is readily per
ccived in increased warmth at quite dis
tance from its source Furthermore. it is
claimed that the rush Of air usually pass
ing up the chimney of an open stove or
CRATE, and which makes this excellent
form of heating apparatus so expensive in
rapid consumption of fuel, is checked and
thrown down on the fuel, producing sur
face combustion, while the draught at the
base may be shut off, giving clear,
bright fire, without wastetul consumption
