dead level of sandy desert relieved only
by palm groves and patches of vegeta-
ton 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 bull
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 neighboring
Arabia. The Arabian shore as far as
can be seen is low and devoid Of water
except at El-katif where similar
springs are found.
Arabs say that these streams come
straight from the Euphrates river

which the great river. In part. flows be

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 watered slopes of
the Persian mountains far to the north
II this theory is correct, 1t means that
the rainfall sinks into the earth's crust
until it reaches impermeable rock
strata along which it is carried for a
great distance to the south out under
the sea until the rock. sloping upward,
again brings the water near the sur

There being no wells within miles of
some of the coast towns of Bahrein,
they obtain water from springs that

far from the shore. These springs of
course have the same origin as the
wells. Divers, with goatskins under
their arms. dive through the salt water
and fill the skins with the cold, fresh
liquid at the bottom. The water OBJ
tanned in this way usually contains
a slight admixtGre of salt water, sc

brought them from the land. The
force of some of the streams as they
come from the earth is SO considerable
that it pushes back the salt water, and
the spring is not mixed with the sea
water for quite a space around the
place of entrance.
1t has been practically determined
within the past few years that the wa
tiers of a small river in West Africa
which disappeared in a fresh water
swamp that has no visible outlet find
their way by an underground channel
into the Atlantic and mingle with the
sea through an opening in the bottom
that has been discovered a few miles
from Cape Verde. A channel has been
found on the sea floor which, appar-
emily, was cut by some fresh water
stream. During some soundings that
were made in 1895 for the purpose of
finding and raising a broken cable the
vessel engaged in the work was sur
rounded by swamp vegetation that was
continually rising to the surface. 1t

The breaking of cable of the mouth
OF the Rovuma river in East Africa
has been attributed to the destructive
action Of a strong current Of sweet
water entering the sea level several
miles from the land. Another remark
