1812 edition. Excerpt: ...by the action of the sea. We used no
gravel for wrecking the work, but in what was above low water, the
interstices were filled by hand, after set with small sharp rubble
stones of the same kind; and it is to be further noted, that the
outside blocks, after being roughly squared, were not laid upon
their beds, but set with their angles upwards, so that every stone
was jambed between two, set in a similar manner below. I am
therefore of opinion that the method proposed will be sufficient to
resist the violence of the sea, when got up to its full height, and
covered with an entire platform of large blocks upon the top. In
regard to the economy that may attend this mode of operation, I
must observe, that in all the piers above mentioned the whole or by
far the greatest part of all the stones employed were not found by
the sea shore, but by necessity brought from quarries by land
carriage, so that the expense upon the whole was not less than four
shillings per ton; and would have been far greater, had nothing but
large blocks been employed. It may therefore in some situations be
better economy to make use of the stones that are there, there, if
large, though rounding, and to fill all solid, than either to break
them to render them angular, or fetch this kind of stones from
quarries within land. It seems therefore probable that something
may be done by way of easing the expense, and increasing the
expedition; but the proper mode of operation depending altogether
upon local circumstances, I am unable to form my opinion fully
thereon without a view of the premises. I am with great respect,
Gentlemen, Your most obedient humble servant, Austbup, j. SMEATON.
