subjected, the observer is soon struck with the signal proofs of
decay furnished by that outer border of the land which is washed by
the sea. The abrupt cliffs that shoot up from high-water mark, the
skerries that rise among the breakers a little way from the shore,
and the sunken reefs that lie still farther out to sea -- all tell
of the removal of masses of solid rock. A little reflection leads
us to perceive that the abrading power of the sea must be confined
to that upper part of the water which is affected by winds and
tides, and that in the deeper abysses there is probably no sensible
erosion of hard rock, though the currents there may be capable of
carrying along fine ooze and silt. The waste which takes place
along the line where land and sea meet has a twofold character. In
the first place, there is a direct abrasion by the sea itself, and
it is this loss which is now to be considered. But, in the second
