Mr Mulcaster 							Farnacres 7th May 1771



      We reced your Letter of the 1st instant wth. the several Inclosures all Safe. Cowhill Cross Vein Lead No 1 Assay 7 oz 15 Dwt 13 8/10 Gns pr fodder No 2 do 6 13 12 6/10

which is very well worth Refining but at the present price of Lead the Black Slag will not answer however there is no hurry about it and in case Lead should fall it will do to Refine amongst the Refineable Slag from the Grey Slags you will therefore take care to let us know some little time before you begin Refining the Slag and Test Bottom Lead and you shall then have full directions what to do.

      Your Computation for supposed Stock of Slags Hearth Ends etc answers our end very well.

      It is certainly right to make another Tryal of Running the Litharge Slags in the Slag Hearth and we shall be glad to hear the Result of it, as you mention, as soon after it is finished as your convenience will permit. We are

      Your most Hble Servts
