casing; eight hundred and seventy-six cubic feet of Mylnefield stone
in the hearting; one hundred and four tons of solid contents; one
hundred and thirty-two superficial feet of hewing in the face-work;
four thousand five hundred and nineteen superficial feet of hewing in
the beds, joints, and joggles; four hundred and twenty lineal feet
boring of trenail holes; three hundred and seventy-eight feet lineal
cutting for wedges; two hundred and forty-six oaken trenails; three
hundred and seventy-eight oak-wedges in pairs.

In the work-yard about sixty men were employed in hewing and preparing
the various courses of the solid part of the building. The second
course, which contained some very weighty stones, was laid down upon
the platform in the middle of the yard, each stone being carefully
fitted and marked as it was to lie in the building.

By the end of this season the building was brought to a level with the
highest part of the margin of the foundation pit, or about five and a
half feet above the lower bed of the foundation-stone. The number of
hours work upon the rock this season at low water amounted to about
two hundred and sixty-five, of which number only eighty were employed
in building.

The third season was commenced early in the spring of 1809. The first
works consisted in laying down mooring-chains with floating-buoys, for
mooring the stone-lighters and praam-boats; the beacon was also fitted
out as a more permanent residence for the workmen, in order to lessen
the amount of sickly motion which is so distressing to landsmen in a
rough sea. By the end of June the men were able to work upon the
masonry while the rock was under water; and on the 8th July, for the
first time, the tide ceased to overflow the building at low water.
With considerable exertion the solid part of the building, which
reached to the height of thirty feet, was completed by September. By
continuing the works a month or two longer a much greater height might
have been attained, but as the engineer foresaw that a diligent
employment of the next season would suffice for the completion of the
work, he deemed it advisable to leave the house in its present solid
defensible posture, on which the sea had much less hold, than if part
of the hollow portion had been built.

The winter months were occupied in preparing the upper courses; but in
consequence of severe frosts, several excellent and valuable stones
from the Mylnefield quarry were
