NOTES WITH REFERENCE TO THE SECTIONS. 
The section through the HaiTogate antichnal may be regarded as approxi- 
mately correct so far as the sm-face is concerned. The folding of the Yoredale 
Rocks beneath the Stray is, to a certain extent, hypothetical. "When the rail- 
way was made across the Stray the beds were obserred to be so much disturbed 
that it was thought by some that the principal axis of elevation was at this 
point, rather than at the Stdphur Springs. 
The MiUstone Grit series consist very largely of Shale. It must not be 
supposed that the relative thickness of the Grits and Shales is accm-ately 
delinated in the diagi-am. Even the Plompton Grits, which form the highest 
section of the Third Grits in this district, are by no means free from associated 
Shales. 
The section from Malham to Skipton is designed to give an approximate 
idea of the position and contorted character of the rocks in the vicinity of the 
Craven fault, and for many miles southward. The sm'face of the valleys is for 
the most part thickly covered with glacial clays, sand and boulders ; but where 
exposui-es of the rock are met with they always exhibit a more or less contorted 
section. At Malham Tarn the Mountain Limestone extends in more or less 
horizontal beds on the upturned edges of the Silmian rocks. The gi-it rocks 
which occupy the higher ground at Hanhth and Flashy Fells are in the form 
of syncHnals, whilst the summit of the anticHnals occupy the lower parts of the 
valleys. At Skipton, a Limestone is quarried, which is supposed to be 
equivalent to the Mountain Limestone at Malham, but this is by no means 
certain.
