At this pit a shaft 6 feet in diameter was sunk to the depth of 173 
feet; a boring of 5 inches in diameter was then made. When the 
boring-instrument had penetrated the saturated plaster or gypseous 
beds to the brine-spring, it suddenly dropped 18 inches, and seemed 
to rest upon a solid substance. Immediately on the spring being 
tapped, it rushed in with such rapidity as to carry one of the men to 
the height of 90 feet before he could be rescued. Brine-pits continue 
to Wheelock, where a considerable salt trade is carried on. 
At the Limekiln pit, or Wheelock Salt-works, is a copious and 
strong brine in constant work. The depth to the spring is 180 feet, 
or 3 feet below sea-level; the depth to the level at which the spring 
stands 84 feet, or 93 feet above sea-level. 
The most westerly pit at Wheelock belongs to the Trent and Mer- 
sey Canal Company. It is situated on the south-west side of the 
river Wheelock ; it is a brine-pit, and is not now worked. 
These pits have been mentioned separately, as they form a line of 
works, situated at short intervals, carrying on the line of section. 
Following the course of the Wheelock, to the west of the shaft or 
pit of the Trent and Mersey Canal, in smking the foundations of the 
viaduct of the Manchester and Birmingham Railway over the Whee- 
lock, brine was reached. About a quarter of a mile lower down the 
Wheelock, and nearer to Warmingham, a boring was made through 
marl 102 feet and then mto gypseous marls 57 feet, in all 159 feet, 
or about 22 feet below sea-level, without findig brine, when the work 
was abandoned. At Pettywood Farm, half-way between Warming- 
ham and Middlewich, on the course of the Wheelock, in boring for 
the foundations of a bridge, gypseous beds were met with at a depth 
of 30 feet, when the boring was discontinued. 
Salt-springs have not, I believe, been actually detected between the 
Wheelock and Weever. South of this point the intervening country
