went to Moorhouse, near which place we saw the till of a 
reddish colour, exposed above twelve feet in thickness, 
without its bottom having been reached. It is full of stones, 
mostly rounded, and consisting of Criffel granites, slates, and 
Silurian rocks, but it is, nevertheless, used for brick making. 
In the neighbourhood of Moorhouse the land is of a cold, 
clayey nature, and covered with considerable beds of peat. 
On passing through Oughterby, Mr. Brockbank pointed out 
the place at Moor Dyke where a small seam of coal had been 
reported to have been formerly worked. We next went to 
Quarry Gill, to look at the so-called mountain limestone, 
which had been quarried many years ago, and which Mr. 
Brockbank thought might probably indicate the position of 
some of the lower coals. That gentleman had found the 
dark shales in Thornby-brook, and from their fossils suspected 
them to be lias, but he never imagined that the Quarry Gill 
stone was anything but mountain limestone, and he quoted 
Professor Sedgwick and other geologists in support of that 
opinion. On going into the field where the old quarry had 
been opened, I picked up a piece of limestone which w’as 
without doubt lias. The old quarry is now filled up, but 
dark lias shales are seen in situ in the ditch near the well, and 
in the well itself the limestone is seen. The well derives its 
water from a bore, which is at present about six feet deep, 
through the limestone. The walls of the well are constructed 
of lias limestone, and that rock is found lying on the surface 
of the field. Herewith are exhibited specimens full of 
GnjphcBa incurva, G. injiata, and G. depressa, and an 
Ostrea, besides other shells. 
At Fisher’s Gill farm a well was sunk through the lias 
shales into the limestone. 
At Thornby-brook, south-east of Aikton, are seen the lias 
shales, first found by Mr. Brockbank. These are met with 
in the brook course, and arc not exposed more than two feet 
in height, and for a distance of under one hundred yards.
