Aynsley John Tweddell & Bacon Wm Wastell are the Defendts. on the part & behalf of the

John Smeaton of Grays Inn in the County of Middx Genm aged 63 yrs or abts being produced as a
witness on the pt & behalf of the sd Complt in the Title of the Interries named was on the 28th Octr 1786 shown
[such?] at the seat of Mr Tancred who is the Clk in Co* for the Deft in the sd Title named by Mr Heatley
one of the Sworn Clks in my office who then also left a note of the name Title & place of abode of the sd
Dept at the seat afsd & afterwards on the same day & yr the sd Dept being sworn & Examd deposeth and sayeth
1st To the first Interry this Dept saith that he knows the Complt in the Title of the [Interrys?] named & hath known
the Complt upwds of 10 yr last past & that he hath also known the Defendts B.W. Wastell & John Tweddell respectly
for upwds of twenty yrs. But he does not know the Deft Gawen Aynsley-
2nd To the second Interry this Dept saith that at some time in or abt the latter End of the year 1776 this Dept
being then at Hexm collectg the Rents of the Derwentwater Estate of which he was one of the agents or
receivers for Greenwich Hospital he was applied to by Mr John Donkin then Steward or agent
to the Complt to know if he this Dept wd undertake the direction of the Building of a Bridge over the
River Tyne at or near a place called the East boat near the Town of Hexm afsd for or on behalf
of the sd Complt in case the Complt shd enter into an agreemt with the Magistrates of the County for this
purpose & in case this Dept shd upon a Survey & examn of the Grd or bottom of the River at or near
the sd place find it such as in the Estimation of this Dept be sufft for the foundn of a Bridge
at that place & this Dept then Enquiring why the Complt confined his enquirey and proposition to or near
that place the sd John Donkin inf this Dept that the Complts Estate lying on the opposite side of the
River there to which an Immediate Communicatn by means of Bridge wd be of so great an
Advantage as to induce the Complt to take upon himself the risk and trouble of the Erection
provided there was a prospect of doing it witht being considerably out of Pockett. But that if he
the sd Complt shd be out of pockett two or three hundred pounds he shd not be dissatisfied in case
a Bridge could be Erected there but if a sufft foundn could not be found contiguous to the Complts
Estate then he shd leave the undertakg to such as shd be more immediately interested therein and
Saith that he belvs that the afsd foundn proposition to build a Bridge at the place afsd or at any other
place near Hexham was in consequence of the Total destruction of a Bridge that had been built
a few yrs before in a Similar Situation opposite the upper pt of the Town of Hexm which was undertaken
& built at the Risk of the late Sir Walter Blackett who in like manner had an Estate lying on the
opposite side of the River Tyne & which Bridge was standing to appearce perfect at the Close of the Day of
the Sixteenth November 1771 & which at day break of the following day was found to be totally thrown down
& demolished by the action of a Flood which in the night had rose to an uncommon hight which
hight was assertained by the Marks it had left but as no one appeas to have been witness to the Catastrophe
no inference could be drawn as to the immediate cause save the uncommon Rise of the Water & which
from the great damages done there & in many or places has since been known by the Appellation of the
Great Inundation and this Dept further saith that the sd Sir Wr Blackett being unwilling to reingage in the [reworkg?]
of the sd Bridge & the utility thereof being fully proved in its short duration the Magistrates themselves
were then induced as this Dept bels to commence undertakers in that Business & engaged Mr Wooler
an Eminent Engineer who in confidence of Bridges made by a Surveyor whom the Magists had
employed for that purpose formed a design for Buildg a Bridge abt 50yds below the former Site and
accordy the North Land Breast or abutmt thereof was completed in or abot the yr 1774 after wch tha the work
might the more ably carried into execution Mr Jona Pickernell an expd workman or foreman was
engaged & brought down from London by the sd Jn Wooler to act under him & as such was engaged by
the Magists who on digging out the foundation for the first pier in or abt the yr 1775 at the Depth of 4 foot
below the bed of the River instead of meeting with a Bed of Clay as reported by the psons employed to
Bore as afsd found a Quicksand of so bad a nature that being viewed by the sd John Wooler and
ried in the presence of some of the Magists he the sd John Wooler declined the furtr execution of the
undertakg on the consn of its being impracticable except at such expenses as were likely to
be far beyond the ability of the County’s Funds to expend And saith that the Magists not yet giving
up the pursuit of a Bridge Advertsmts were contind in the Weekly Newspapers for psons willing to become
undertakers And they also Expended sums of Money in the furr provision of Materials and such was
the state of things as this Dept verily bls when the sd John Donkin applied to this Dept as before
mentd he this Dept havg had many opportunities of information by reason of his frequent visits
to Hexm as afsd and this Dept further saith that it then appeared to this Dept that the subsequent operations of
the sd Mr Wooler had cloased up & explained the cause of the failure of Sr W. Blackett’s Bridge
for it had appeared to this Dept (who had in consequence of his own Curiosity occasionally viewed
it) that it had been as he thought suffly secured by piles and plank under the piers accordg [to?]
the accustomed method of Bridge Buildg in Rapid Rivers insomuch that the perpendicular
hight alone to which the water rose in the great inundation of the yr 1771 & which was [??]
only apparent cause that was extraordinary, did not seem sufft in this Depts opinion to overthrow
so large & so well established a Structure in so short a space of Time as the compas of a single
Night & more parlarly as it had been erected by experienced Workmen, but when the sd John Woolers
operations had discovered the practicability that the same stream of Quicksand had extended under
Sir W. Blackets bridge & that according to the usual practice & which occurred on this Deponents
inspection as afsd they had Dug so deep into the upper crust of Gravel forming the Bed of the River
in order to establish their foundation upon piles the piles had then in reality no other bearing
than in a Stratum of Quicksand of a Depth unfathomable & consequently the piles being
undefended if the action of the Current water in passing through the Bridge was sufft to
remove the natural Bed of Gravel from the side of any one of the piers and proceed to undermine
the Base thereof the Arches of which the Bridge consisted were of so large a Span of so little elevation
& in consequence so flatt & in or respects were so constructed that the whole of the Bridge wd give
way in consequence of the destruction of a single pier it thereby appeared that the whole Structure might
be totally demolished in so short a space of Time as before mentd & this Dept is furtr confirm’d in this opinion
