THE MAKING OF AN ICEBERG.

they have been stranded. that there Is
the greatest danger to the mariner
The bergs have their origin almost
exclusively In western Greenland. al

some from Hudson bay
A huge sheet of Ice a mile thick In
places covers the whole of Greenland
This gradually slides down the valley
toward the sea, into which II Is thrust

these ends become too heavy they
break Off and become bergs The proc

broken and continue to diminish In
size until they finally disappear com.
pletely. The process sometimes takes
several years.
Once set adrlft lcebergs End their
way into the Labrador current and be-
gin their Journey. But of all bergs so
set adrift only a very small proportion
ever find their way into the path Of the
transatlantic steamships.
Nor do all bergs take the same
course. Some go south; others lodge
against the shore or against islands.
Two years may separate the time that
two bergs reach low latitude. though
they were "calved" at the same mo.

Field Ice also offers an obstruction to
the icebergs, though by their great
size and bulk they often act as pows
and aid materially In breaking up the
fee fields which obstruct the arctic ba.

Ice fields are more affected by the

ally drift with the current, so that one
sometimes Is seen moving into the
wind.
Advantage is taken of this by the
sealing and fishing boats when caught
In an ice ield. They often moor to an
iceberg and are towed miles through
the ice, through which otherwise they
could make no headway. This is ac-
complished by sinking an anchor into
the berg and using u strong towline.

same end. In July and August. when
the bergs are breaking up along the
coast OF Labrador the noise at times

ten causes another to break up.
From their very nature icebergs as
sumo an endless variety of shapes.
Some resemble geometrical figures,
while others carry fantastic domes,
spires aud minarets. Sometimes they
appear TO be veritable ice bridges,
with two separate supports. In many
there are great caves and lndenta-
tions. AS they drift south and begin
melting cascades Of water pour down
their sides or run from the tips of the
hundreds OF icicles which depend from
every ledge.
Frequently there are outlying spurs
in the water, as dangerous to ships as
submerged reefs. For this reason YES.
sells should always give them a wide
berth, half mile being considered the
nearest that one may be approached
with safety.
Several years ago the British steam
ship Nessmore ran into an iceberg and
stove In her bows. When she was
docked a scratch was found next the
1Ieel the full length Of the ship, the
plates being almost cut through. The
ship evidently struck q submerged
spur. The government report says:
''It is generally best for ships to go
TO windward OF them, because disin-
tegrated fragments have a tendency to
drift to leeward, while open water will
be found TO windward."
So nicely are icebergs balanced In
the water that the slightest melting
sometimes will cause the center of
gravity to shift, and the entire berg
will capsize or founder. Thus many
ships have been wrecked.
Field ice Is formed throughout the
waters within the arctic circle south
as far as Newfoundland. and each
year vast foes leave the shores and
drift south into the paths OF COM
