The accompanying view shews the entrance into Newton Dale, and it is rather extraordinary that Fen bog, which fills the central part of the view, and over which the railway is carried for about a mile, should be the site of the summit level. The spring which feeds this bog is one of the sources of Pickering Beck, which uniting with the Derwent, pours its waters into the Estuary of the Humber, and joins the sea, after a course of nearly a hundred miles, though rising out of the side of a hill which commands an extensive view of the German Ocean, at only a few miles distance.
