49 
and well notes which have been placed at my disposal. Mr. Bland’s 
paper, already alluded to, is entitled, ‘‘ Measurements of the Altitudes 
of the Hills and Valleys and the Depths of Wells through a Part of 
Kent, undertaken for the purpose of ascertaining the Height of the 
Springs above the Sea-level,” and referring chiefly to the Chalk in and 
around Sittingbourne in the years 1827 and 1828, with the rainfall 
and state of the weather from 1819 to 1829. Privately printed at 
Sittingbourne. For the loan of this interesting paper I am indebted 
to the Rev. C. J. Wimberley, Sibertswold Vicarage. 
Notes on the Petham Nailbourne from 1772 to 1869. Communi- 
cated by Mr. James Reid, of Canterbury. ‘The Nailbourne came 
into Shamford Street, Feb. 22, 1772, and continued to run through 
the street till June 16, 1772. It came into the street again, March 
7, 1774, and continued running till June 28, 1774. It came into 
the street again Jan. 12, 1775, and again Feb. 26, 1776. This 
Nailbourne ariseth at Dean, in the parish of Elmsted, and at Duck 
Pit in the parish of Waltham. This by Thos. Page.” From other 
data this Nailbourne ran in Jan. 1860, Feb. 1861, 1864, to June, 
1865, and slightly in 1866, 1869, and Jan. 1873. 
Notes on a Well at Elmsted Vicarage. Communicated by Rev. G. 
A. Collett. “This well was sunk in the Vicarage garden in 1884, at 
an elevation of 500 feet O.D. Water was first reached at 180 feet. 
Waiting for this to lower, the well was continued to 248 feet, where 
a good head of water was met with. The strata met with were firstly, 
11 feet of diluvial matter, stones, clays, etc., called locally ‘clay 
pillars.’ All below this, Chalk without flints, with joints few and 
far between, the Chalk so hard that it had to be blasted with gun- 
powder, no need to ‘steen.’ We sent up at 58 feet some palatal teeth 
of fish, and lower down fragments of Inocerami. Below 220 feet 
the Chalk was more jointed and easier worked. The springs rise and 
fall here in a very wonderful way, they are usually highest in May 
and fall till January, when they begin to rise again. In December, 
1884, I ran my well dry, but kept sounding it in January, 1885, 
expecting water. On the 13th it was dry, next morning I found 
_ fourteen feet of water, which soon increased to 40.” 
In the tabulated list of wells appended, I have given the height 
above O.D., the depth of well, and the water-level (where this 
information is given), but in most cases, especially in bored wells, 
the latter is not very conclusive. For other particulars of well- 
sections I must refer my readers to the Memoirs of the Geological 
Survey, vol. iv. pt. 1, by Mr. W. Whitaker, B.A., F.G.S., and the 
Quarterly Journal of the Geological Society, vol. xlii. p. 26. I have 
confined my observations chiefly to the water supply. 
I am indebted to those gentlemen whose names appear in the 
Appendix of Well-sections (p. 50) for much valuable information.
