Cities That Now Tower Above Its
ShorIs-
Government geological experts have
calculated that New York, Boston.
Philadelphia and all the other cities
along the Atlantic coast will eventual
ly sink beneath the ocean. They have
observed that there has been a steady
sinking or the whole coast, and they
say that it is going on at the present
moment ss>s--s--->---
/ Biologists have long recognized the
fact that the Atlantic coast line was
much farther out than it is now. There
is line from 100 to 300 miles off the
present coast at which the water sud
denly gets deeper. Out to that distance
the water is generally about 800 feet
deep. Then it plunges suddenly and
becomes ten times as far to the oceans
bottom. The men of the coast survey
have traced this line throughout the
length of our coast line and find it
similar all along. The geologists say
that the continent once reached out
that far and that there was the coast
line, but gradual decline through the
ages has caused that line to retreat.
until now it is where we know it.
From a geological standpoint this
has happened in comparatively recent
times 1t has all been done since the
glacial period This brings it into the
present period and makes the action

be going on now.
There is an ancient sill in the Charles
town navy yard at Boston with re-
gard to which there is definite informa-
ton as to its elevation. 1t was put
In place seventy years ago; its eleva-
tion was given with relation to mean,
high and low tide. and also with refer
ence to surrounding landmarks. With
relation to the tide this sill has sunk
seven-tenths of foot With relation
to the landmarks it has the same posi-
ton, positive proof that Boston har-
Dor and the city about it have sunk
seven-tenths of foot into the sea in
the last seventy years.
The original mouth of the Hudson
river is now 200 miles out to sea. The
ships follow its old channel in leaving
port even now. 1t is not known how
long ago it was when the mouth Of the
river was not far out in the ocean. But
1t is almost certainty that when a
similar time has elapsed the present
city will be an equal distance from the
then land
Similarly will Boston be submerged
Baltimore will disappear at about the
same time and great portions of Wash
ington. The great Mississippi is bring
ing down great deposits to raise it's
delta and counterbalance the decline.
So low is New Orleans that it will be
one of the first cities to sink below the
sea level and be municipality high
walled against the enemy, the sea- Gal
weston has already felt the encroach-
ment of the waters and has been forced
to build itself sea wall
The geological survey makes topo-
graphical maps. On these lines are run
at given elevations For instance. a
line may be run about Manhattan Is
land at level twenty feet above the
water al the Battery. 1t would sub
merge the customs house and extend up
Broadway nearly to Wall street. From
the east 1t would invade the financial
district almost to Nassau street 1t
would overflow half the land between
the city hall and the East river. Far
ther up it would submerge a narrower
strip, but its intrusion would create
great havoc
A fifty foot rise of water would wipe
Manhattan Island out entirely. Of
course, if these depressions came on
very gradually the water fronts would
be diked against their intrusions. In
this way New York city might be saved
from destruction for very long time.
1t will inevitably become a city sur
rounded by high levee, against which
the ocean will beat with an ever in
creasing advantage. 1t might perpetu-
ate itself by artificial means, but in the
end it will be put in an impossible posi-
ton. The waters will follow over the
fats of New Jersey and of Long Island
They will even beat back through
the Delaware and the Chesapeake and
get beyond the city and cut off com
munication with the main part of the
land. Finally, New York will find it
self a city down in we'll far out from
the mainland. Gradually the people
who dwell in it will desert it and re-
pair to the then mainland. The waters
will eventually lap away the great
walls that have been built to keep out
the sea and will tumble in among the
