Extract

In framing a theory attributing the terraced form of limestone outcrops in the Yorkshire Dales to glacial erosion, Mr. Goodchild was doubtless prepared to encounter much adverse criticism. If in this communication I venture to differ from his views, he will believe that it is in no captious spirit. The district in Northumberland from which I write supplies materials for criticism of the most relevant kind, presenting as it does the same series of Carboniferous rocks cropping out in surface features closely allied, and subjected in the Glacial Period to the pressure of the same ice-sheet. The terraces of Wensleydale, too, are not wholly unfamiliar to me.

page 27 note 1 Exceptional cases occur in which such ponding did take place. In these the waterflow found itself barred by accumulations or intercepted by basins, neither of which existed before the Glacial Period.

page 29 note 1 In many cases the two harder beds are so rapidly undermined, owing to the hollowing out of the shale, as to have little chance of becoming weathered to any great extent.

page 30 note 1 That this is the case is, I think, indicated in Phillips's Geology of Yorkshire, Section Physical Geography.
