Excerpt from The Wilkinsons: Family of Ironmasters

by Frank Dawson

(a biography in preparation)

....

Two questions emerge, now that a substantial sum of money is available and a group of Subscribers formally identified to carry the work forward. If Wilkinson, with Pritchard, conceived the revolutionary idea of an iron bridge in the first place why did he not at this stage undertake the iron work of the bridge himself? And was Abraham Darby, a comparative youngster, capable and confident enough to cast the huge spans that Pritchard’s design demanded even with all the experience of the Coalbrookdale Company behind him?

Wilkinson’s position is not difficult to explain. Concurrent with the bridge planning is the introduction of Watt’s New Steam Engine and the rapidly expanding demand for iron cylinders and castings from Wilkinson’s works, in addition to steady government orders for his guns. He is at full stretch to supply existing demand for iron products on top of which his brother is about to leave Bersham for France, increasing his supervisory and management responsibilities. He is shrewd enough to see that compromise is required, that his influence must be behind an iron bridge but that someone else would build it.

The Darbys were the obvious choice. Their works were close to the proposed site for the bridge and they had generations of experience as Ironmasters; and there was a tenuous link with them going back more than twenty years to Isaac’s arrival in the district and his lease of a Darby furnace. There might even have been an element of patronage in Wilkinson’s approach to young Abraham the Third though exactly how he came to be proposed and chosen as the bridge builder is not recorded.

From the beginning there is evidence of an anxiety in the Darby camp that the money would not be enough and that they were engaging in frontier technology the cost of which could not be precisely forecast. Abraham’s fears are not articulated in so many words in the minutes but the subscribers are at great trouble to reassure him. Yes, they concede that if there is opposition to the Act there will be more expense, and they will defray that cost. Yes, certainly any further subscriptions received should be paid to the Darbys.(9)

How far the reassurances were successful has to be in doubt as a consequence of an entry in the Minute Book three months later which is surprising and irregular. A meeting is recorded as taking place on 22 January 1776 at Abraham Cannadines which is Wilkinson’s Broseley meeting place.

“It was agreed that a new subscription paper be prepared with a new preamble setting forth that the several subscribers advance a proportion of their money subscribed towards obtaining an Act of Parliament for building a bridge from Benthall to Madeley Wood at the place first agreed. It was likewise agreed that no opposition or intention of an opposition was or is intended to be made to the erecting a bridge over the Severn at the Sheepwash by any of the proprietors of the intended bridge from Benthall to Madeley Wood.” (10)

No list of persons present is given. The minute is not signed. There are no other minutes. Moreover the handwriting of the first long sentence looks suspiciously like John Wilkinson’s flowing well formed hand. The handwriting of the remainder is clearly by someone else.

What is happening here? A new subscription paper called for, allocating only a proportion of the money already subscribed to the original bridge; and another bridge proposed lower down the river, to which no opposition or intention of an opposition was or is intended, by the Subscribers presumably?? It can only be designed to put pressure on someone, but whom? And who exactly is applying the pressure? Are the Subscribers now split?

The next two meetings make things a little clearer and provide further evidence that Abraham Darby continues to be worried about costs. On 25 April 1776 they discuss ways of limiting the competition to the bridge in the form of boats and ferries; and in the important meeting of 15 May 1776 a further charge on the Proprietors is agreed to repair approach roads though this had been specifically included in Abraham Darby’s overall responsibility when he was given the money more than six months previously. But that is not all. Two further minutes come as a shock.

“It was agreed to rescind minutes entered into with Mr Darby for erecting an Iron bridge over the Severn between Benthall and Madeley the 17th October 1775”

and,

“Agreed that an advertisement be inserted in the next Birmingham and Shrewsbury newspapers to be continued three times, that any person willing to undertake the building of the intended bridge from Benthall to Madeley Wood, one arch 120 feet span, the superstructure 18 feet in the clear and the centre 35feet above low water, the proposals to be sent to Thomas Addenbrooke before the 20th June next.”(11)

Abraham Darby clearly wishes to be free of his commitment to build an iron bridge and the committee agree to release him. At the same time they choose to go ahead with a bridge as planned and to the original specifications but since iron is not mentioned they seem prepared to consider a conventional design. There is a further development at the next meeting on 28 July 1776. Presumably no satisfactory tenders have been received by the deadline of 20 June and there have been further discussions resulting in a modified plan for the bridge again produced by Pritchard(12). This plan has not survived. How far it differed from his original is not known, but the committee now agree

“…that advertisements be inserted in the Birmingham and Shrewsbury newspapers for persons to undertake the stone and brickwork…”(13)

There is now a ten week gap in the record. It would be invaluable to know how the decisions and dealings of the committee up to this point affected the relationship between John Wilkinson and Abraham Darby III. They were so far the only Ironmasters involved with the resources to erect an iron bridge. It is also important to remember that Abraham Darby III was only twenty-five years old, not yet fully come into his powers, not yet confident perhaps to treat with a man like John Wilkinson, forty-eight years old, a shrewd businessman and a very experienced Ironmaster. It may be that the later appearance of Richard Reynolds on the committee of subscribers was a studied move on the Darby side to support young Abraham. Reynolds had earlier been totally responsible for the Coalbrookdale Company and was a highly respected figure in the area. He was also an Ironmaster with business knowledge and experience to match Wilkinson.

It is not difficult to imagine the frustrations surrounding Wilkinson at this time, urgent in his enthusiasm to see the iron bridge built, unable to commit more of his energies and resources to it, determined to see the project through and casting around for a way to get it started. From what happens next it seems clear that he found a formula to persuade, perhaps even to compel, Abraham Darby and the Coalbrookdale Company to undertake the work and to get on with it quickly.
