them), besides such as are visible and above water, which gradually
lessen the quantity of water that would otherwise lie with an
infinite weight and force upon the land. It is observed that these
rocks lie under water for a great way off into the sea on every
side the said two horns or points of land, so breaking the force of
the water, and, as above, lessening the weight of it.

But besides this the whole TERRA FIRMA, or body of the land which
makes this part of the isle of Britain, seems to be one solid rock,
as if it was formed by Nature to resist the otherwise irresistible
power of the ocean. And, indeed, if one was to observe with what
fury the sea comes on sometimes against the shore here, especially
at the Lizard Point, where there are but few, if any, out-works, as
I call them, to resist it; how high the waves come rolling forward,
storming on the neck of one another (particularly when the wind
blows off sea), one would wonder that even the strongest rocks
themselves should be able to resist and repel them. But, as I
said, the country seems to be, as it were, one great body of stone,
and prepared so on purpose.

And yet, as if all this was not enough, Nature has provided another
strong fence, and that is, that these vast rocks are, as it were,
cemented together by the solid and weighty ore of tin and copper,
especially the last, which is plentifully found upon the very
outmost edge of the land, and with which the stones may be said to
be soldered together, lest the force of the sea should separate and
disjoint them, and so break in upon these fortifications of the
island to destroy its chief security.

This is certain--that there is a more than ordinary quantity of
