Modern mill tail race.


The Ordnance Survey 1:2500 First Edition mapping of 1869 shows a building together with the annotation, 'Chemical Works'.


The chemical works was provided with a water supply by means of a leat and a millpond.


A tail race returned water to the Glen Auldyn watercourse 190m downstream. Its precise route is not entirely clear on the OS mapping, nor on the ground, and it may have been culverted along its upper course. Its outfall, to which the grid reference relates, is still apparent.
