Knareshorough Section. 



From the last-described section to the fine escarpment on which 

 the remains of Knareshorough Castle stand, the Sandstone can be 

 seen on the banks of the Nid, with one exception, where the Mag- 

 nesian Limestone comes in by a fault. Under the castle the yellow 

 Limestone graduates, as it passes downwards, into a yellow calcareous 

 sand, much false-bedded; and this rests on a thin red parting of 

 Conglomerate, varying from four to six inches in thickness, under 

 which, quite unconformable to the Permian strata, lies a reddish- 

 brown Sandstone, harder than any of the rocks before-described, but 

 composed of similar quartz grains, cemented together with decom- 

 posed felspar. The rock contains many remains of ordinary Coal- 

 plants, most of which have lost all their external characters. Among 

 them are Calamites and a stem of a plant resembling a, Dadoxylon, 

 which before its compression must have been nearly a foot in 

 diameter. The dip of the Sandstone is to the E.S.E. at a moderate 

 angle. The position of the beds will be seen in the accompanying 

 woodcut.

From Knaresborough to Fountains Abbey I saw little of the 

 country, so as to enable me to trace the Sandstone in its northern 

 range. 



Section from Fountains Abbey to Bipon. 



Many years ago I remember seeing a coarse gritstone, of a brownish 

 colour, dipping under yellow Magnesian Limestone. This Sandstone, 

 which contained a large quantity of decomposed felspar, very much 

 resembled the Bramham Moor Stone previously described. It dipped 

 to the south-east, at an angle of 12'-', and was succeeded by a bed 

 of Flagstones, containing markings like the tracks of some animal 

 inhabiting a bivalve shell. These flags reminded me of the Lower
