INCREDIBLE Announcement

Tides OF the Ocean.

London. March Camille Flamma
rinon has a way OF occasionally NJ.
tering sensational statements con. ]
cerning some natural phenomenon
which startles the public. but which
on investigation, proves TO be familiar |
to all scientists. Thus last Sunday he
made what he described as an al !
most incredible announcement that
the solid earth experiences twice a
day undulations corresponding TO the
tides OF the ocean. The only startling
feature OF this announcement Is that
It should have startled anybody.
That the attraction of the moon,
which causes such obvious periodic
movements OF the waters Of the sea
must produce a similar effect on land
/ the crust of the earth. has been rec
/ ognized by physicists and astronom.
/ ers for many years On Monday
night. for instance, Sir George Oar
win in addressing the Authors club
az the weekly house dinner on the
subject of the influence Of tides on
man. referred 10 the experiments ne
and his brother Horace had made
twenty-five years before In an effort
to measure the durnal rise and fall
OF n given point on the lands surface
under the influence Of the moon. Sir
George confessed their failure. but
coniectured from the observations
lately made By Or. Hecker at eBrlin
that in this latitude the land and
wave rose and fell four or five inches
Sir George said:
Or Hecker's apparatus is in n
chamber cut out on the side Of a
b. we'll eighty feet below the earth's
surface. and he has continued 10
. make observations by means of pho.
Biography day and night for six years.
. II is from these observations that It
is possible TO determine how stiff
the earth IS. Il Is just about as stiff
as If made Of steel II It were made
, of steel It would move up and down
one-third as much as if liquid through
out.
Sir George traced the history OF
, thority on tides dwelt in his address
.
the planetary system. pointing out
especially how the friction OF the
tides acts as a brake on the earth's
rotation and reacts on the moon, the
effect being 10 slow down the spin.
ming time Of the earth and drive the
=. moon further away.
Sir George traced the history OF
the earth and moon from the time
when the latter was thrown off from
the former, probably leaving the hole
now filled by the Pacific ocean. For
awhile the two bodies side by side
went spinning around. Then the tidal
frictions drove the moon away and
I, will drive il further and further,
while It checks the rotation of the
) earth. When the terrestrial day is a
I month long the moon will again al
ways face the same side of the earth.
DR.. Hecker explains his methods as
. follows:
when a ship mounts the crest of
wave the masts lean backward, and
a plummet hanging from the top OF
the mast will always swing from the
base. Likewise II you suspend a plum
met from a peak or column standing
firmly on the surface Of the earth,
the plummct will oscillate as a tidal
wave rolls along the land. If we use
Won Rebeurs horizontal pendulum We
are capable OF recording oscillations
up TO a one-twenty five-thousandth
, OF an inch
, Sir George Darwin did not refer 10
the experiments of DR. Won Rebeur
Paschwitz. who has been working al
land tide measurement, nor TO the in
. vestigations carried on the last few
years at the Kimberley observations
, which seem to show that the crust OF
, South Africa rises and falls eight
, inches daily. Neither did he discuss
, the possibility OF utilizing the energy
