On examining into the conditions of the task which had devolved upon
him, he came to the conclusion that the structures of his
predecessors had both been deficient in weight; and that if Rudyerd's
had not been destroyed by fire, it would not much longer have
resisted the fury of the tempest. He announced his intention,
therefore, of raising a fabric of such solidity that the sea should
give way to _it_, and not _it_ to the sea; and he determined to build
it entirely of stone. Moreover, Winstanley and Rudyerd had wasted
much valuable time, from the difficulty of landing on the rock, and
the impossibility of working on it continuously for any length of
time. But Smeaton proposed to moor a vessel within a quarter of a
mile of the scene of action, which should accommodate his company of
workmen; and thus they would be prepared to seize every opportunity
of launching their boat, and carrying their materials to the rock,
instead of making a long voyage from Plymouth on each occasion.
So far as concerned the design of his intended erection, he was ready
to adopt Rudyerd's idea of a cone, but he proposed to enlarge its
diameter considerably; and the type he kept constantly before his eye
was the trunk of an oak tree, which is equally remarkable for
gracefulness and strength, and withstands successfully the most
furious gales, when other forest trees are bent or broken.
The autumn of 1756 was occupied in the transport of the granite and
other materials to the rock, in their preparation, and in the
excavation of the steps or stages on which the foundation was to be
laid.
[Sidenote: Laying the foundation.]
Early in June 1757 the work of erection began. The first stone,
weighing two tons five hundredweight, was laid on the 12th. On the
next day was finished the first course, consisting of four stones, so
ingeniously dove-tailed into one another and into the rock as to form
a single compact mass. The sloping form of the rock, to which the
foundation was, of course, adapted, required only this small number
of stones for the first course; the diameter of the masonry gradually
increasing until the highest level surface was reached. Thus:--

The second course, completed on the 30th of June, consisted of
thirteen blocks of granite; the third course, completed on the 11th
of July, of twenty-five; the fourth, on the 31st, of thirty-three.
The sixth course was laid down by the 11th of August; and as it rose
above the high-water mark, Smeaton was entitled to consider that he
had conquered the greatest difficulties of his task.
[Sidenote: Fixing the blocks.]
Up to this point the mode of procedure in laying and fixing each
great block of granite was as follows:--
