the arctic does and causes the bergs TO
melt and Hoat from the places where
they have been stranded, that there Is
the greatest danger TO the mariner.
The bergs have their origin almost
exclusively In western Greenland. al.
though a few may come around Cape
Farewell from the Spitzbergen sea and
some from Hudson bay.
A huge sheet Of Ice mile thick In
places covers the whole Of Greenland.
This gradually slides down tho valley
toward the sea, into which II Is thrust
in great sheets 6fty miles wide. As
these ends become too heavy they
break OF and become bergs The proc

set adrift thus may be thousand feet
out Of the water and a mile square.
but as they drift about they become
broken and continue to diminish in
size until they finally disappear com
pletely. The process sometimes takes
several years.
Once set adrift icebergs find their
way into the Labrador current and be-
gin their journey. But OF all bergs so
spt adrft only 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.
ment.
Field ice also offers an obstruction to
the icebergs. though by their great
size and bulk they often act as plows
and aid materially in breaking up the
ice fields which obstruct the arctic ba-
sin.
Ice fields are more affected by the
wind than are icebergs. Bergs gener-
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 field. They often moor to an
iceberg and are towed miles through
the Ice, through which otherwise they
could make no Roadway. This is ac-
complished by sinking an anchor into
the berg and using a strong towline.
As the berg advances open water. with

the bergs are breaking up along the

is deafening. and the noise of one Of

Field ice is formed throughout the
waters within the arctic circle south
as far as Newfoundland. and each
