SPRINGS IN THE SEA
FRESH WATER STREAMS THAT BURST
FROM THE OCEANS BED.
The Origin of the Underground Riv-
ers That Have an outlet Under the
Persian Gulf Has Never Been Salts

| through which water as pure and fresh
as that Of any bubbllng spring mingles
with the salt water OF the sen. Anoth-
er remarkable class OF fresh water
springs is those that sink out OF sight
or perhaps never come 10 the surface,
but follow hidden channels under the
land and under the sen until they final
ly come to the open air on an Island.
Both OF these types Of underground
rivers are perhaps most remarkably IL
lustrated near and on Bahreln island,
IN the Persian gulf, place that Is also
noted as one OF the chief sources OF
pearls.
Bahrcln Island, the largest OF the
group Of islands bearing that name, Is
about twenty miles off the cOast OF
Arabia I'm the Persian gulf. AS the Is
land has almost no rainfall II Is a
dead level OF sandy desert relieved only
by palm groves and patches Of vegeta-
tlOn where water springs To the sur
face from the mysterious underground
channels. In many places the water
does not reach the surface, but Is found
by sinking wells, the water being rails
ed TO the surface by donkeys and bul-
locks and poured into the channels
from which the date palms and other
crops are irrigated. These springs can
not possibly be derived from the island,
and II is no more likely that they come
from the sandy wastes OF neigbborlng
Arabia. The Arabian shore as far as
can be seen is low and devoid OF water
except at El-Katlf where similar
springs are found.
Arabs say that these streams come
straight from the Euphrates river
through IN underground channel by
which the great river. In part. flows be
meath the Persian gulf. Biologists,
however, have dismissed this theory.
Though the origin OF the springs has
not yet been satisfactorily explained,
the most favored theory is that they
come from the well watercd slopes OF
the Persian mountains far TO the north.
II this theory Is correct. IL means that
the rainfall sinks into the earth's crust
until II reaches impermcablc rock
strata along which IL Is carried for n
grcat distance To the south out under
the sea until the rock. sloplng upward,
again brings the water near the sur
face on Bahreln island. Some Of the
wells that are thus supplied are enor-
nous, and one OF them, the Adari,
serves for the irrigation OF many miles
Of date palms through n canal Of an
Client construction. The Adari well Is
one OF the great sights OF Bahrein, be-
ing deep basin OF water 22 by 40
yards I'm size. The fact that II comes
from far higher source Is shown 10y
the force with which II enters the well.
Divers, driven back by the strong cur
rent, are unable to reach the bottom.
There being no wells within miles OF
some OF the coast towns Of Bahrein,
they obtain water from springs that
Issue from the bottom OF the gulf not
far from the shore. These springs OF
course have the same origin rs the
wells. Divers, with goatskins under
their arms, dive through the salt water
and fill the skins with the cold, fresh
liquid mt the bottom. The water OBJ
tanned In this way usually contains
a slight admixture of salt water. so
that the mixture is just little brack-
lsh. At some of these openings at the
sea bottom the head OF water entering
the sea Is so strong that when hollow

who are sitting I'm the boats that
brought them from the land. The
force OF somV of the streams as they
come from the earth Is SO considerable
that II pushes back the salt water. and
the spring Is not mixed with the sea
water for quite n space around the
place OF entrance.
1t has been practically determined
within the past few years that the wa
ters OF n small river I'm West Africa
which disappeared In n fresh water
swamp that has no visible outlet find
their way 10y an underground channel
into the Atlantic and minglc with the
sea through an opening In the bottom
that has been discovered few miles
from Cape Verde. a channel has been
found OH the sea floor which. appar-
emily, was cut by some fresh water
stream. During some soundngs that
were made in 1895 for the purpose of
finding and raising n broken cable the

rounded 10y swamp vegetation that was
continually rising TO the surface. II
was evidently brought through the un.
derground channel from the swamp.
The breaking OF cable Off the mouth
OF the Royuma river I'm East Africa
has been attributed To the destructive
action OF n strong current OF sweet
water entering the sea level several
miles from the land. Another remark

found Co the north of the city OF AFRICA
