Letter – Nicholas Walton to John Ibbetson – 28 Apr 1775

Jno. Ibbetson Esq.                                    			Farnacres 28th April 1775



Sir

       Inclosed you will receive a Computation of the Expence of Buildings etc in addition to the Smelting Mill and Conveniences at Langley Castle Pasture, on acct of the increased produce from the Lead Mines in the Manor of Alston moor amount to the Sum of £229.4.3 1/2.  In Mr Walton's Letter of the 17th Ult it was suggested that an addition of two Hearths would be necessary; but on considering this matter attentively, we propose to try what can be done by the addition of one Hearth til it is seen whether the increase of Duty Ore is likely to continue; at the same time we propose to erect it in such a way that another may afterwards be added in case it is found proper.  One of the Cottages proposed at the Mill is now Building, and we expect will be ready for a Tenant by the 12th of May, but as we cannot easily situate the other, without being rather inconvenient to some of the Works, we think it best to postpone that til we see further.   We have engaged a Tenant for the Cottage now Building.   As what we now propose seems unavoidable, we have endeavoured to avail ourselves of the early part of the Season by making the necessary preparations, which we flatter ourselves will meet with the Boards approbation.  We apprehend that in case the quantity of Ore continues, that an additional Peat House will be necessary, but this we postpone for the present for the reasons already given.         

       We are etc
