The reason why it occupied so much time in building was, because
the men could only work in the summer months. The first summer was
occupied in making holes in the rock, and fastening irons to hold the
future work. The second year was spent in erecting a solid pillar,
of fourteen feet diameter, and one hundred and twelve feet high, for
the future support of the building. The third year, it was augmented
in diameter and increased in height. This building was eventually
finished, within the time above-mentioned, at an enormous expense. It
stood the opposition of the elements. The violence of the sea was so
great, that Mr. Winstanley said it has been seen to rise upwards of
one hundred feet above the vane, whilst the sides of the building were
covered with surf as with a sheet, so that the whole house and lantern
were occasionally under water. This edifice withstood the conflict of
elements till 1703, when the architect, being at Plymouth, and desirous
of visiting it, for the purpose of inspecting some repairs, went to
it, but returned no more; for a storm arose, which left not a relic
of it standing, except the iron work, which had been fixed in the
rock. The Corporation of the Trinity House had then to erect another,
for which purpose they employed a Mr. John Rudyard, who was a silk
mercer, on Ludgate-hill. Mr. Rudyard’s mechanical ingenuity was said
to have qualified him well for the undertaking. It appears that he
erected a house made chiefly of wood, which presented many traits of
his genius. It was a conical frustrum, one hundred and fifty-six feet
in diameter at the base; its altitude sixty-two feet. At the top of
the building was a balcony, railed round; in the centre of its area
was the lantern. This building was made quite plain, excepting the
well for the staircase, which was solid for thirty-two feet. In the
centre a strong mast was erected. The building was admirably fixed to
the rock, from the very peculiar manner of making the holes to hold
iron cramps, they being made for the internal cavity to diverge on
each side, by an extreme of one inch at the depth of sixteen inches.
The cavity was first filled with tallow; the hot iron then dipped
in the same substance, put in the rock, and eventually filled with
pewter, which displaced the tallow, being heavier, the grease serving
to protect the iron from the corrosive acidity of the salt water. In
1708, it was finished so far as to receive a temporary light. It stood
forty-four years, and showed that it was liable to destruction from the
very perishable nature of its materials. However, on the 2nd December,
1755, the upper part of it taking fire, burnt downwards to its entire
consumption. The concern had been leased to a Captain Lovell; but at a
later period his possessions were distributed among a number of people,
when the care of rebuilding it was entrusted to Mr. Robert Weston, to
whom Mr. John Smeaton was recommended by the President of the Royal
