Letter – Nicholas Walton to Peter Mulcaster – 9 Jul 1770

Mr Mulcaster.                             					Farnacres. 9th July 1770



      I have reced your letter of the 5th instant inclosing the Operation Paper and Assays of Old Cowslitts Ore.

      You are right in the 450 Ounces you had it 450 1/16 in your Letter but we could not make more than 450 of it neither do we go so near in the Weighing as Sixteenths.

      The other Piece by your Operation and Letter weighed 373 3/16 if it had Weighed 373 4/16 we should have reckoned it 373 1/4 Ozs: but as it fell Short of the Quarter we only called it 373.

      I entirely approve of your raising the place for the Peats in the manner you mention but thing there should be some dry Rubbish such as small Stones or small broken pieces of Bricks etc wch come out of the Furnaces.  Do you think covering the Turf might be useful. 

      I dont know but I shall be at the Mill about the beginning of next Week I cannot however be certain of that.

      I will make Enquiry about the Fume of the Lead. In the meantime it will certainly be proper to take care of what is produced at Langley Mill.  

      I am Your most Hble Servt

      Nich Walton Junr



PS. Old Cowslitts Ore is not Refinenable.  I take it for granted the Assay was made from Lead made at the Hearth.  I desire Thorngill Slag Lead may be Refined  for the Time to come.  And, I desire youll take a Chip off every piece of Common Lead til which and til you get a Line from me how the Assays turn out I would have you deliver Refined Lead.
