Letter – Nicholas Walton to Peter Mulcaster – 20 Dec 1774

Mr Mulcaster.                              			Farnacres 20th December 1774



       Having now tried the weight of the Assays inclosed in your Letter of the 14th inst (which are exactly of the same weight) you have as above the weight P Fodder left in the last Refined Lead as also in all the other Parcels of Refined Lead from which we have had Assays since our beginning to Refine at Langley Mill from those you will observe a considerable difference between the Work now and formerly.  We are sure we need not say anything to you by way of inducing you to do every thing in your power to put the Workmen into a right way, for it cannot now admit of a doubt but that the fallings short of late must have been owing to some errors in the Work.   We shall, as soon as it can be conveniently done, make out an Account showing the produce of Bullion at Langley Mill compared with the Assays and send you a Copy.  We are

       Your hble Servts
