a circular opening in which it is said the flagstaff of the lordship or barony used to be erected when vassals from the neighbourhood were summoned to battle; at this position it would have been visible to all parts of the barony and beyond. but it is more likely to be a natural cavity caused by weathering. The farmer, Mr Craig, was not sure in 1895 if the stone was genuine, we will never know as the Bore Stone was broken up in about 1950 according to Mrs Raeside of Borestone Farm.

It remained in that family until at least 1876. James Wilson of Thirdpart was a notable local eccentric who wrote and published poems on such topics as the 'Trearne Cattle Shows', the 'Fall of Giffin Castle' and the 'Misfortunes of a clocking-hen'. James died in 1838. William Wilson who lived here in 1837 was a brick and tile maker. A small mansion had been present here, occupied in the 1570s by John Montgomerie of Scotstoun, a near relative of the Laird of Hessilhead. A dreadful series of incidents occurred in the locality, starting on 19 July 1576 when the Lady of Hessilhead slapped one Robert Kent, servant to Gabriel, brother of John Montgomerie, for some grave offence given. The servant complained to his master and Gabriel went to his brother at the old Thirdpart mansion for advice. John advised him to seek revenge and therefore the next morning Gabriel and Robert gained entry into Hessilhead castle where they found the lady alone, upon which they grabbed her by the hair, pulled her onto the floor, kicked her in the bowels, and bruised her shamefully. Gabriel intended to shoot the Laird, however the whole household was now awake and the two only just managed to escape by stealing a horse and locking the castle gate from the outside. The Laird, Hew Montgomerie, hastened to Thirdpart where John and Gabriel came out with pistols and drawn swords and attacked Hew Montgomerie, injuring him on various parts of his body
