Huge Inaccessible Mass of Iron Ore In
Russia.


Russia.
Science has just demonstrated that
there lies under the historic Russian
town of Moscow a mass of iron ore
miles in length and breadth, and pow
erful enough to defect the magnetic
needle and pull a plumb line from the
vertical throughout a large region;
but investigation also makes it proba-
BILE that this mass is about seven miles
below the surface-a fact calculated to
cool the ardor of spectators for some
time to come. We translate from
''Gaea," Leipsic, April, an account of
the discovery of this inaccessible ore
bed. which human eve has never seen:
when recently, for the first time in
fifty years, new triangulation of
European Russia had been begun, the
remarka BILE fact was discovered that
in the neighborhood of Moscow the
plumb line suffered very notable de-
Walton from the vertical. This devia-
ton appeared greatest within zone
that extended about forty kilometers
ttwenty-four miles, north and south
and one hundred and eighty kilometers
lone hundred and twelve miles, east
and west. Here the lower end of the
line was deviated eleven seconds to the
north of the vertical About twelve
kilometers seven and half miles
south of Moscow, on line running
approximately east and west, its direc-
ton is normal. while farther south the
lower end of the line is deviated about
ri ha
noteworthy a deviation of the line
in a level region seems TO indi-
cate that heavy masses OK consider
able thickness must be stu
ated there, under the earth's
surface. Great masses of iron were
naturally thought of first. and an at
tempt was made TO demonstrate the
existence of such masses by means OF
measurements OF terrestrial magnet
ism. The scientist II. Fritsche. so well
known on account Of his researches in
terrestrial magnetism, made, in June,
1898, magnetic survey of the neigh
borhood of Moscow for eighty kilone-
tiers fifty miles around. The terres-
trial magnetic elements we're precisely
measured for thirty-one localities, aud
