New Red Marl was about 106ft., of the more arenaceous Marls 
passing into sandstone and fine Conglomerate 99 ft. Total of New 
Red 205 ft. (c) Though the water level was found 14 feet below 
' the surface, yet the chief supply of water at a temperature of from 
53° to 54° was reached at the first appearance of the arenaceous 
beds, ie., about 130 ft. below the surface, and yielded 2,000 
gallons per hour. (d) That most probably the Coal Shales which 
succeed the New Red beds were touched at 219 ft. below the 
surface, and that the boring was judiciously abandoned at this 
point, and the bore hole covered over. — 
Another trial hole has been sunk subsequently to the above at 
a spot much lower down and nearer to the river. Owing to the 
numerous step faults which abound in this district and the 
consequent Southerly dip of the strata, the Black Rhetic 
Shales alone were reached without touching the New Red Marls. 
After passing through the Grey clays and piercing a band of 
White Lias, the true “Cotham Marble” resting upon the Avicula 
contorta Shales, a plentiful supply of water..was tapped. This 
seems to have been found just at the junction of that band and 
the Black Shales, This well has been for the present stopped at 
the depth of 33ft. 
So far as to the succession of beds proved by the well boring 
and sinking. Now for the sections exposed in the various excava- 
tions carried out for the roads and the foundations of the 
buildings to be erected. 
The best section of the White Lias and Rhetic Shales was 
exposed in a square pit at the N. side of the ground not far from 
the rails excavated for the chimney stack, and 22ft. higher than 
the surface of well on S. side. This gives.the clue to the true 
succession. The following section shows the White Lias and 
succeeding beds to a depth of about 14ft. 6in.
