| with the proceedings of the works of the Bridge from first to last as well as the other defendts | ||||
| because as Chairman of the Quarter Sessns he had an opportunity of [???] Conversing with the sd | ||||
| Jonan Pickernell on the Subject & as the sd Magists after his appointmt as Deputy Surveyor under the | ||||
| sd Mr Wooler had appointed him the sd Jonan Pickernell to be Surveyor of the Bridges under them | ||||
| for the County of Northd & the sd Jonan Pickernell had also been recommended by two of the sd Magists | ||||
| of sd Co to act under him as Deputy Surveyor in this work He for these reasons concluded | ||||
| that the Defts as well as the sd Magists were well satisfied with all the proceedings especially | ||||
| as he never reced any objection thereto from the sd Defts by the sd Jonan Pickernell or otherwise | ||||
| & this Dept furr saith that exclusive of findg the sd Jonan Pickernell to be a pson likely to ansr | ||||
| the purpose in point of Experience & Capasity as Deputy Surveyor in this work it was a considble | ||||
| inducemt to Dept to consent to his being so Employed because being previously employed & | ||||
| recommended by the Magists as afsd he trusted that the confidence the Magists reposed in him | ||||
| wd obviate all objections in leaving any thing short or Insufficiently done in the afsd Work | ||||
| 3rd | To the third Interry this Dept saith that not havg any concern in the Expenditure of the money or in | |||
| keeping the Accot relating to the sd Bridge He cannot say wt the sums Expended really were but he | ||||
| has reason to believe that a Stone Bridge upon a Gravel Bottom Extendg 518 feet betn its | ||||
| 130 | abutmts over one of the most rapid Rivers in this Kingdom that Dept is acquainted with must in | |||
| its nature Cost more than the sum of 5,700£ & he has still greater reason to think so because this | ||||
| Depts estimate upon the Plan origly Exhibited was for a greater sum & it is not frequent that | ||||
| works of that kind are performable for less money than their Estimation & furr saith that a Considble | ||||
| sum of money must necessarily be expended in additional works that this Dept could not forsee | ||||
| in consequence of Misfortunes that really happd in the course of the Execution & agst Wch attacks | ||||
| he this Dept thought it necessary to make aditional defences to the works. | ||||
| 4th | To the fourth Interry this Dept saith that in the Beging of the Mo of Jany 1781 He surveyed the Bridge | |||
| in Question in presence of Two of the Magists who as this Dept was infd & verily bels were appointd | ||||
| 30 | by the Bench of Magists to view the same one of whom |
|||
| the Defendt Wastell & found every thing done to his this Depts great Satisfaction as well as to | ||||
| the satisfaction of the Magists then attendg & this Dept gave a Certificate to the [Complt?] that the | ||||
| Bridge was completed accordg to the complts agreemt. And this Dept further Saith he hath been infd | ||||
| & bels that the sd Bridge stood safe & unhurt & witht the least appearance of Injury notwithstanding | ||||
| that sevl grt floods happd during the Intermediate time but that upon the 11th March 1782 a more | ||||
| sudden & violent flood happd than had happd since the grt Inundation of 1771 & which flood | ||||
| of 1782 being at the highest in the Middle of the day the circumst attendg it were more capable | ||||
| of being observed than that which in the |
||||
| and saith that this Dept having been infd by the sd John Donkin & which he bels to be true that he the sd | ||||
| John Donkin parlarly observed the hight of the Water acting agt the Bridge upon the west or up stream | ||||
| Side of the Bridge & that it rose on that side to the top of the Caps of the Salient points of | ||||
| the piers but that on the down stream or East Side the Surface of the Water scarcely arose so | ||||
| high as the Bottoms of the Imposts & therefore from the Diffce of perpendicular hight of those two | ||||
| fixed Marks this Dept calculates that the velocity of the River's Water must have been at least | ||||
| at the rate of 1000 Cubical feet in a minute but that the sd Donkin was so far from apprehendg | ||||
| any danger to the Bridge itself that he had just sent his Son with some Masons over it from the | ||||
| North to the South End to examine the state of the Detach'd Land Arches which had also been erected More | ||||
| for the Safety of the Bridge in time of violent Floods which they reported (& still remain) safe | ||||
| but that very soon after the Main Body of the Bridge began to show symptoms of failure & in | ||||
| Half an Hour the greater pt of it was bron into that state of Ruin in which it now |
||||
| and this Dept furr saith he bels the failure of the Bridge was not caused by any Defects [??] in | ||||
| or in the construction thereof but that he same was entirely due to the unusual suddenness | ||||
| & violence of the flood at the time mentd & the Dept is the more confirmed in his belf therein because | ||||
| in the yr 1779 when all the piers of the sd Bridge were laid in the River but the upper works | ||||
| not compleated there then happd a flood so remarkably violent that accordg to the observn | ||||
| of the sd Jonan Pickernell which he soon aftr reported to this Dept the Diffce of the Level of the | ||||
| Water betwn the upper & lower or down stream side of the Bridge was three feet nine Inches | ||||
| & wch accordg to the computation of this Dept wld necessarily produce a velocity of the Currt | ||||
| Water at the Rate of above 900 feet in a minute & wch as the sd Jonan Pickernell then reportd | ||||
| to this Dept was so far from producing any derangmt in the Bridge that on the contrary | ||||
| such changes as had been made thereby in the Bed of the River were for the better as | ||||
| it had acquired a more equal depth from side to side and saith that aftrwds the sd Jonan | ||||
| was for his good services in the undertaking recommended by this Dept to the Commrs | ||||
| of the [piers?] of Whitby Harbour and that Robt Thompson who through this Business had acted | ||||
| =4 as foreman Mason under the sd Jonan Pickernell & been chosen by the Magistrates to the | ||||
| surveyor of County Bridges, the report of the sd Robt Thompson as was Communicated by the sd | ||||
| John Donkin to this Dept & which he verily Bels to be true was that every great flood wch | ||||
| happd from the time of his appointmt to the day of the Destruction of the Bridge had in their sevl | ||||
| Effts rendered the Bridge more unsafe because thereby the shallow pts of the Bed of the River | ||||
| were made deeper & the deep pts by the desposing of Gravel brought down had become Shallower | ||||
| 5 & 6 | To the fifth & sixth Interries this Dept saith that in case another Bridge is to be built or | |||
| attempted to be built over the River Tyne in the place of or near to the last that in order to make | ||||
| or render the same safe & secure from the like Accident as afsd that the same shd be erected | ||||
| or attempted to be built after some or plan that is upon some or principal of Construction | ||||
| as to its foundn than that whereon the former Bridge was made by the Complt but as this | ||||
| Dept Cannot Suggest any principal of construction he can esteem to be secure notwithstg | ||||
| the experience he has gained since he began the former Bridge it is not of His power to form | ||||
| any estimate of the Cost that may attend it & this Dept furr saith that he does not see any | ||||
| reason to Expect a better Success in a future than with the former Bridge while the plan | ||||
| & place remains the same nor hath he yet been infd of any or Situation in the Neighbourhood | ||||
| of Hexham that he now has any reason to think preferable to the situation of the Last Bridge | ||||
| Last | to the Last Interry this Dept saith that had he been acquainted with certain facts in the year 1776 | |||
| he is now in posson of he certainly shd have judged the prospect of Building the sd Bridge as | ||||
