"London, Broad Street Buildings, No. 13. Sept. 9, 1788.--That I am a bad correspondent is so general a complaint against me, that I must expect the same accusation from you--But hear me first--When there is no matter to write upon, a letter is not worth the trouble of receiving and reading and while any thing which is to be the subject of a letter, is in suspence, it is difficult to write and perhaps best to let it alone--'least said is soonest mended,' and nothing said requires no mending.
"The model has the good fortune of preserving in England the reputation which it received from the Academy of Sciences. It is a favourite hobby horse with all who have seen it; and every one who has talked with me on the subject advised me to endeavour to obtain a Patent, as it is only by that means that I can secure to myself the direction and management. For this purpose I went, in company with Mr Whiteside to the office which is an appendage to Lord Sydney's--told them who I was, and made an affidavit that the construction was my own Invention. This was the only step I took in the business. Last Wednesday I received a Patent for England, the next day a Patent for Scotland, and I am to have one for Ireland.
"As I had already the opinion of the scientific Judges both in France and England on the Model, it was also necessary that I should have that of the practical Iron men who must finally be the executors of the work. There are several capital Iron Works in this country, the principal of which are those in Shropshire, Yorkshire, and Scotland. It was my intention to have communicated with Mr. Wilkinson, who is one of the proprietors of the Shropshire Iron Works, and concerned in those in France, but his departure for Sweden before I had possession of the patents prevented me. The Iron Works in Yorkshire belonging to the Walkers near to Sheffield are the most eminent in England in point of establishment and property. The proprietors are reputed to be worth two hundred thousand pounds and consequently capable of giving energy to any great undertaking. A friend of theirs who had seen the model wrote to them on the subject, and two of them came to London last Fryday to see it and talk with me on the business. Their opinion is very decided that it can be executed either in wrought or cast Iron, and I am to go down to their Works next week to erect an experiment arch. This is the point I am now got to, and until now I had nothing to inform you of. If I succeed in erecting the arch all reasoning and opinion will be at an end, and, as this will soon be known, I shall not return to France till that time; and until then I wish every thing to remain respecting my Bridge over the Seine, in the state I left matters in when I came from France. With respect to the Patents in England it is my intention to dispose of them as soon as I have established the certainty of the construction.
