1t is curious fact that u ball fired

Russian railroads and sugar refner
les are disusing the Ostrian and Carwin
coal and buying English coal. It seems
the Russian vessels, after carrying car
goes of produce to England, find it diff
fcuIt to obtain anything to take back,
and SO they offer to take coal at very
low rate rather than ship ballast.
The projected elevated circular rail.
way for Vienna has been accepted by
potion of the municipal council. The
plan, which was drawn up by American
and British engineers, and is supported
by the government, comprises a length
of twenty y-eight miles in all. The CEN
tral station will be in the Franz osef
park, and it is to be so constructed
that fish-market can be established
underneath it. The average height of
the line above the roadway will be
sixteen feet, and the line will be sup
ported upon groups of three columns,
eleven inches in diameter. AS space
of from sixty to eighty feet will occur
between the columns. 1t is estimated
that the cost Of the road will be about
$25.000,000.
In note by Mr.. w. J. MCGEE on
local subsistence produced by an ice-
sheet, he calculates that a sheet of ice
three miles thick ought to depress
the crust of the earth about 500 or 600
feet, and then he goes on to say that
''the hydrostatical principles in accord
ance with which deformations beneath
thick ice-sheet must occur &c ually de-
mand that the crust should return to
its original form after the melting of
the ice, and ii is manifest that as much
time would be required to produce this
secondary as the primary reformation.
Assuming, then, that the period of ad-
vance and retreat or of growth and de-
cay of the ice are Of like duration, it
follows that the earth's surface must
continue below the normal level at any
latitude after the withdrawal of the ice
for as long a period as that during
which the ice remained stationary at
that latitude.
France was the first country to en-
ploy electricity for the transmission OF
power in practical way. The ST.
Claude shaft. 1t BlanZy, was sunk to
the depth of 1,G40 feet, for the purpose
of searching for the faulted portion of
coal seam, and heading was run
from it across the strata. When this
heading had reached length of 1872
feet, the ventilation became so poor and
the temperature so high (95 degrees
Fahrenheit that the miners could
work only few hours. After some
Intellectual measures to improve the
ventilation by simple mC ans it was de.
cided to put in fan 2 63 feet in diam.
eter, and run it by power transmitted
by electricity. An eight.horse portable
engine was put up above ground, and
with it "a Gramme dynamo electric
machine was run at the rate of 100
revolutions per minute. The electric
current thus generated was conducted
10y cable consisting Of seven 0044
copper wires TO Il second Gramme
machine coupled directly to the fan and
placed in the heading near the shaft.
