Abstract
The new quarry in which these sections are exposed lies to the north of the quarry, hitherto called Redhall Quarry, and is separated from it by the canal and the Caledonian Railway. Both quarries are in the same line of strike in the carboniferous rocks, which dip to the west along this line. Unfortunately, a large portion of the beds overlying the sandstone had been removed before I saw the sections, and the process of sloping the banks had been going on for some time—a very unlucky proceeding for the geologist. Still, there was enough left to show the very interesting and instructive sections we have in this locality. At the south end of the quarry, where the process of tirring was going on when I first observed it, the sandstone beds, as I have remarked, dip to the west. At the east side of the section the beds are sharp, unweathered, and truncated, the spaces between the ends of the beds being firmly packed with hard, dry boulder clay, full of both angular and rubbed stones. The two lowest beds of sandstone exposed are each four or five feet thick. The ends of these beds are also truncated, showing as it were a cliff from eight to ten feet deep, facing the east. This is also filled up with boulder clay, enclosing large angular blocks of sandstone, evidently derived from the end of the beds, and also a large number of smaller stones, scarcely any of them rubbed or
