In transcribing the following passage from Smith’s text, I have begun with the rough OCR material provided by the Internet Archive and then collated it with the Internet Archive’s page images. If you spot any errors, please notify the webmaster. — George P. Landow
The blue lias limestone, composed of thin beds of stone; imbedded in clay of the same colour, lies at the edge of the blue marl district, and makes a surface so little differing from that of the blue marl as to be frequently passed without notice. The white lias beneath it is still less seen except in particular parts of Somersetshire,' where its planes happen to be parallel to the surface of arable land, and fragments of its flat beds turned up with the plough. These rocks are better exposed in the quarries of Somersetshire than in any other parts of their course. [47]
