NOTES ON THE DRIFFIELD AND MARKET WEIGHTON RAILWAY. 
BY REV. E. MAULE COLE, M.A. 
The coiLstiTiction of a new railway, however small, affords oppor- 
tunity for fresh geological sections. In the present instance the line 
is only 13^ miles long, and presents no new features, hut it is 
interesting in some respects, especially at its western end, where it 
shows the position of the chalk as regards the underlying beds. 
It was pointed out long ago by Phillips that a sub-cretaceous 
anticlinal existed somewhere about Garrowby, stretching east and 
west, which seemed to cut off the Oolitic rocks in North Yorkshire 
from those southwards about ^larket Weighton, but whether these 
rocks were removed by denudation previous to the deposition of the 
chalk, or thinned out against an old submarine shore-line was doubt- 
ful. The question is by no means settled yet, but the facts are 
these : the Lower Calcareous Grit and Oxford Clay of the Middle 
Oolites make their last appearance from the north at Hanging 
Grimston, near Acklam. The estuarine sandstones of the Lower 
Oolites share the same fate, except for a small patch at Kirby Under- 
dale and Grimthorpe. These latter come on again south of Market 
Weighton. Between Hanging Grimston and Sancton the rocks, 
which underlie the chalk, are composed of Lower Lias, so that a vast 
gap appears . The mass of rocks, which constitute the moorland of North- 
East Yorkshire, consisting of estuarine sandstones, with their inter- 
calated marine limestones, notably the Scarborough, Millepore and 
Dogger beds, which attain at the Peak a thickness of 600 feet, are want- 
ing, as well as the Upper and Middle Lias. A well, sunk 300 feet, 
at Huggate, revealed the fact that these beds were absent far within 
the present western contour of the Wolds. It is, therefore, clearly 
established that the non-appearance of these rocks is, at all events, 
not due simply to the overlapping of the chalk. 
I am inclined to think, though I speak with hesitation, that the 
anticlinal above-mentioned is not improbably connected with tlie 
ancient anticlinal from the west, noticeable at Harrogate, and that 
the Liassic beds of North Yorkshire were deposited in a separate area
