Letter – Nicholas Walton to Peter Mulcaster – 10 Nov 1781

Messrs Mulcaster                                 					Farnacres 10 Novemr 1781 



       I now inclose you the remaining calculations as to Refining - The way I make out the Table No 3 is as follows.

Produce of No 1 Lead Silver and Savings               £633.18. 9

              2 Do.        at 5s P Fodder less price  £625. 7. 6 3/4

            Decrease in produce by lowering price 5s    £8.11. 2 1/4

Value of Lead & amounts of Charges Pr No 1 £634. 1.  3/4

Do at 5s P Fodder less price Pr No 2        624.14.  1/2

    Decrease by lowering price 5s P Fodder              £9. 7    1/2

    Increase produce by Refining                       £   15.10 1/4



And therefore as the difference of 1d p Ounce for silver on 188 ¼ ounces is 15/8 ¼ I proceed as follows to make up No.3

Loss

Less as pr No.1 Silver at 6/3d & lead at £16.15        £    2  3 3/4 

                6.2 & lead at £16.15 decreases by 1d fall  15  8 1/4

                                             Loss          18

                6.1    Do                                  15  8 1/4

                              Loss                      £1 13  8 1/4



And so until silver comes to 5/6d p ounce                 Gain

Less as pr No.2 Silver at 6/3d & lead at £16.10         £   13  6 1/2 

                 6.2 & lead at £16.10 decreases by 1d fall  15  8 1/4

                                              Loss           2  1 3/4

                 6.1   Do                                   15  8 1/4

                              Loss                       £  17 10



To find out how I am to proceed after No.1 I say

No. 1 loss was  £    2  3 3/4

   Advantage by 5s lowered in price of refined lead pr No.2 15 10 1/4

   Silver at 6s/3d & lead at £16.10 Gain pr No.2            13  6 1/2 

          At 6/2   & do       decrease by 1d fall           15  8 1/4

                              Loss at 6s/2d                  2  1 3/4



       I desire youll Copy Nos 1,2&3 the former upon half sheets & the latter upon a Whole Sheet which will take it in if you get as much in as I have done in the Copies sent you wch I doubt not youll be able to make out.  If you understand the whole on considering, it is very well, but if you do not I certainly will make it clear when you come down about the Money for the Pay of the Ore Carriers which we would not chuse to be till after Christmas Holydays..   

       I am.  Your Humble Servant
