Paper, 'Barium sulphate as a cement in sandstone' by Frank Clowes

Description

Clowes writes: 'About six miles west of Nottingham [England] there are two prominent conical sandstone hills which are so different in appearance from any surrounding elevations of the surface as to arrest attention. These are known as Stapleford Hill and Bramcote Hill. In the gap between them stands a remarkable sandstone pillar, some 30 feet in height, and 70 feet in circumference, and distinctly crowned by a flattened mushroom-shaped cap. This is locally known as the Hemlock Stone. The sandstone beds forming these hills and columns have been classed by geologists as the Keuper basement beds of the Trias.'
