PALMOZOIC ROCKS BENEATH NORTHAMPTON. 491 
per day, as tested by pumps. The water stood at 170 feet above 
sea-level, or 20 feet higher than at the Kettering-road boring. 
Though in both instances the borings failed to provide the pure 
water, for which object they were carried out, yet the results are of 
the highest interest, and prove the extension of the Paleozoic rocks 
in a new area in Britain. 
The results obtained from these two borings are much strength- 
ened by the fact that they were executed with the diamond drill *, 
by which means the solid cores which were extracted (at times as 
much as 24 feet in length) of the strata passed through showed 
distinctly the exact position of the several beds and the nature of 
the junction between them ; the fossils could also be collected per- 
fect and from each particular horizon. The largest cores extracted 
were from the Kettering-road boring, and measured 197 inches in 
diameter, the cores of the Carboniferous strata at a depth of 851 feet 
measuring 143 inches. 
The Gayton boring was commenced with the 18-inch “ crown,” 
giving 144-inch cores, and during the progress through the 994 feet 
the size was reduced six times, the last core measuring 6 inches in 
diameter f. It was not found practicable to test the direction of 
the dip of any of the strata.

(fig. 5, p. 496). 
A boring has just been accomplished by the Diamond Rock- 
boring Company in Harrington Dale, near the village of Orton, 5 
miles to the west of Kettering and 12 miles north-east of North- 
ampton, to test the possibility of Coal occurring in that neighbour- 
hood. Through the kindness of Mr. J. Fleming, of Newcastle- 
on-T'yne, the owner of the estate, for whom the boring was carried 
out, I was permitted to examine the cores during the progress of 
the operations, the results of which I am pleased to be able to lay 
before the Society. 
_ The position of the boring was upon the outcrop of the Upper 
Lias and 374 feet above sea-level. The Lias clays were pierced at 
. 666 feet, the lower portion differing from the beds at Gayton in 
the absence of fossils, and from those at Kettering road in that 
beds of indurated clay and limestone were not met with. The clays 
were followed conformably by a bed of White-Lias limestone, 
similar in lithological character to the same bed at Gayton, but con- 
taining no sandy veins or fossils. ‘The green shale (beds 6 and 8) 
is identical in appearance with bed 8 at Gayton; it is impossible 
to see any difference in them when examined side by side. It is 
also curious to remark the general similarity between this boring
