OS. The area is later marked as a fox covert and the old road down from Floors ran beside it. An unusual feature of Kilmaurs Mill was a carved stone showing a millstone drive spider or rind (often used on Miller's tombstones as a symbol of the milling trade) on which the upper grindstone rested, a ring of rope, a bill for dressing millstones, and a grain shovel. A ball of fine-grained sandstone, 2½ ins in diameter, with the surface ornamented by six equal, circular and slightly projecting discs, found at Jock's Thorn Farm (NS 417 410). 387 are known from Scotland, but only two from Ayrshire. They are from the neolithic or Bronze Age and their function is not known, however they may be symbols of power, equivalent to the orb in the British Coronation ceremony. In 1911 McNaught records the last sighting of an otter. This took place at the Brackenburn Bridge on 9 September in full moonlight. They have probably made a comeback in the last few years (2000–2006). Next to the St Maurs-Glencairn church is a patch of woodland which was once an orchard. The Tour streamlet joins the Carmel nearby and before the confluence can be found an old well, arched over, known as the Lady's well, with never-failing, excellent and refreshingly cool water. A small wooden bridge used to run across to it from the church glebe side. Lord John Boyd Orr, awarded the Nobel Peace Prize was born in Holland Green on the Fenwick Road in Kilmaurs. He may have been related to the Orr's of Townhead of Lambroughton. The dovecot at Tour below St Maurs-Glencairn Church is dated 1636 on its door lintel (not 1630 as stated by McNaught). It is rectangular on plan, with a centre ridge roof and crow-stepped gables. Only the foundations of the tower still exist, the remains having been taken down in the late 20th century. Kilmaurs was spelt Kylmawse in circa 1564 (1980). The fields below the kirk, running down to the footbridge over the Carmel are named in the 1860 OS. 'Broomy knowe', presumably named after broom and the knowe on which the old orchard was situated, lies to the left of the Tour rivulet. Bounded by the hedge on the right and the rivulet on the left is the 'Dovecot Fauld'. The Scots term 'fauld' means a meadow which is manured by keeping animals
