certain, that we saw not a river, or
stream of water, on all the coast of Georgia, nor on any of the southern
lands. Nor did we ever see a stream of water run from any of the
ice-islands. How are we then to suppose that there are large rivers? The
valleys are covered, many fathoms deep, with everlasting snow; and, at
the sea, they terminate in icy cliffs of vast height. It is here where
the ice-islands are formed; not from streams of water, but from
consolidated snow and sleet, which is almost continually falling or
drifting down from the mountains, especially in the winter, when the
frost must be intense. During that season, the ice-cliffs must so
accumulate as to fill up all the bays, be they ever so large. This is a
fact which cannot be doubted, as we have seen it so in summer. These
cliffs accumulate by continual falls of snow, and what drifts from the
mountains, till they are no longer able to support their own weight;
and then large pieces break off, which we call ice-islands. Such as have
a flat even surface, must be of the ice formed in the bays, and before
the flat vallies; the others, which have a tapering unequal surface,
must be formed on, or under, the side of a coast composed of pointed
rocks and precipices, or some such uneven surface. For we cannot suppose
that snow alone, as it falls, can form, on a plain surface, such as the
sea, such a variety of high peaks and hills, as we saw on many of the
ice-isles. It is certainly more reasonable to believe that they are
formed on a coast whose surface is something similar to theirs. I have
observed that all the ice-islands of any extent, and before they begin
to break to pieces, are terminated by perpendicular cliffs of clear ice
or frozen snow, always on one or more sides, but most generally all
round. Many, and those of the largest size, which had a hilly and spiral
surface, shewed a perpendicular cliff, or side, from the summit of the
highest peak down to its base. This to me was a convincing proof, that
these, as well as the flat isles, must have broken off from substances
like themselves, that is, from some large tract of ice.

When I consider the vast quantity of ice we saw, and the vicinity of the
places to the Pole where it is formed, and where the degrees of
longitude are very small, I am led to believe that these ice-cliffs
extend a good way into the sea, in some parts, especially in such as are
sheltered from the violence of the winds. It may even be d
