of the River: and in a Conversation with Sir Walter Blackett after the
founding of the Bridge was done Sir Walter observing to Mr Smeaton that
a Rumour had gone forth, that the founding of the Bridge had not been made
sufficiently strong Mr. Smeaton said that they had encased the Circumference
with plank or sheet piling, as he had done in all the Gravel foundations
of the kind that he had had the ordering off, it was all he should have done
more than was done, but as the laying of a Solid Platform and even the piling
itself, were things that our forefathers had not generally practised in such
cases; and yet we found many of their Bridges standing after many
years Trial, it must be something very Extraordinary, that could hurt a
foundation, so laid farr beyond any thing wherewith we were then ac-
-quainted.
This serves to show what the opinion of Mr Smeaton was at that time
before any derangement had happened, so that it was a matter to him of
very great surprize, that notwithstanding the extraordinary height of the
water, a Bridge so founded, should be so entirely demolished, in so small
a space of time: But when the operations of Mr Wooler were known, his
surprize ceased, looking upon it as a certainty, that the violence of the water
having taken off the Crust of Gravel, wounded also by the excavation for
the Piers, so as to let loose the Quicksand, he no longer wondered at the
sudden demolition of the Bridge.
The 3rd matter to be observed is that Mr Smeaton had at that time
(that is of Mr Donkin’s application) finished with Success two Capital Bridges
in Scotland, over two of the reputed most rapid Rivers of their magnitude
in that part of Great Britain, that is, over the Tweed at Coldstream which
was finished in or about the year 1767; & which the Tay at Perth which was
finished in or about the year 1770 and which in the interim to Mr Donkin’s
application had sustained many severe attacks from Floods; but without
any injury except (in some slight degree) to the rough rubble Stone deposited
round the Piers by way of defence, and by which being occasionally replaced, the
whole remained and still remain unhurt.
