After reading "An illustrated guide to the stone antiquities on the north yorkshire moors by E. Ogilvie and another booklet by Stanhope White I went in search of two inscribed by Thomas Harwood at Glaisdale.
The first at NZ742030 was easily found at the start of the bridleway leading up to Red House.
The inscription now partially obscured reads; "Francis Hartus to repare this yat and yatstead T.H.1737"
This second inscribed stone was much harder to find as both authors gave wrong grid references. The stone is not
propped against the wall as one author claims but is a part of a large stone in the base of the wall. at NZ 740033.
This inscription reads:- JOHN CAMPION GRANSIR: GAT: LEVE:OF:GAMPLIN:FROM STILE:TO COME: AND: TAKE:UP:THE:UPER END OF WATSON:COW:CLOSE:GREAT HARDIL TAKEN UP AFTER JOHGN CAMPION:GRANDSIR: TOLD THE LOW END OF WATSON:HI: HARDIL JOHN CAMPION: TOLD: THOMAS:HARWOOD:OF TAKING THEM UP:
apparently this is a record of a legal trasaction about the right of way for his friend John Campion who farmed at High Hardhill.
