Abstract
IT is not surprising that the earlier geological writers on the district north and west of the Silurian and other hills of Lakeland, and between the River Caldew and the Solway, should have arrived at diverse conclusions as to the affinities of certain sandstones and shales of reddish or purple-grey tint, which are now known to occur at various horizons in the Carboniferous series. For this district presents unusual difficulties to an understanding of the disposition of the rocks beneath the Glacial Drift.
