THE MIDDLE LIAS OF NORTHAMPTONSHIRE. 
cnssion, lienee I have incorporated them in the descriptions 
of wells below. The “now” refers to 1881, the date of Mr. 
Sharp's paper. 
Kingsthorpe Shaft. When first made the water from 
the Marlstone rose to within 60ft. of the surface, i.e., there 
was a head of 150ft at least. 51 ' No water now flows. 
Mr. Brettel’s Foundry Well, in Cow Lane, Northampton, 
was made about the same time as Kingsthorpe Shaft, and bad 
a deptli of 178ft. It was sunk 104ft., and bored 74ft., and the 
water rose to within 30ft. of the surface, thus giving a head- 
level of 140ft. Now dry. (No doubt this “head” would 
have been greater but that the water ran away into the Inferior 
Oolite, a kind of ragstone, as it is called in a report I have 
since seen.) 
Barracks Wells. Two wells were sunk in the Barracks 
yard many years ago, at least previous to 1847 ; the first had 
a total depth of 174ft.; the second was sunk to a depth of 
140ft., and bored to a further depth of 106ft., thus making a 
total depth of 246ft. 
County Jail Well. This was sunk 102ft., and bored 
72ft., making a total depth of 174ft. 
The last three exhibited the same decline as Mr. Brettel’s 
well, have been disused many years, and I believe filled up. 
The Waterworks Wells. Three wells altogether have 
been made in close proximity to each other, near the Billing 
Road, in Northampton. The water rose at first from a depth of 
168ft. to within about 70ft. of the surface, thus giving a “ head” 
of over 90ft., but during the time pumping was continued, 
i.e., from 1846 to 1885, this diminished till the water had to 
be extracted directly from the rock itself. After a period of 
rest of less than two years (1885— 7) the water has again 
risen between 40ft. and 50ft., and probably would have 
risen higher but that it has been again used, as a supple¬ 
mentary town supply. 
The Reservoir Well, on the Kettering Road, made only 
a few years ago, never yielded much water. I am not in 
possession of any particulars with respect to it. 
Kettering Furnaces Well. This well was finished in 
1878; it had a diameter of 6ft., and passed through 13ft. of 
Inferior Oolite, 157ft. of Upper Lias clay, and 14in. of 
Marlstone, a 5in. bore hole being earned a few feet lower. 
The water rose very little above the Rock-bed. Through the 
kindness of Mr. H. Sartoris, I am able to add that the water 
* If my estimate of the depth of the Marlstone be accepted, this 
should be ‘213ft.
