 at Rendlesham House).

Water stands at 29 feet from the surface ; it is very chalky and bad. There 

 are 40 feet of copper pipe in the chalk. 



No. 96. — Well at Hemley, 4^ miles S. by E. from Woodbridge. 



Feet. 



1 . Loamy soil 6 



2. Crag 44 



Total,. 50 



No. 97. — Well in Havergate Island, 8 miles S.E. from Woodbridge, 

 (height of surface, 4 feet above low water mark of sea). 



Ft. In. 



1. London clay — blue clay, with usual rocky concretions. . 80 



2. Rock 2 



.3. Plastic clay — sand 20 



Total,. 100 2 



N.B. The slope of the plastic clay, from Harwich to Havergate, gives 

 about 3 feet in a mile ; which agrees with the computed slopes of the chalk 

 (see Nos. 16 and 18) the average of which is 3 feet; proving the original 

 conformability of the beds. The distances and bearings are calculated from 

 the Ordnance maps. 



P.S. Since the above memoranda were committed to the press, 1 have 

 been informed that cement stones have been found in great abundance at 

 Assington, near Sudbury ; but whether they belong to the beds of the Lon- 

 don clay, or are drift septaria from the diluvial clay, I do not know. If the 

 former, Layham (p. 362) is not the most westerly point of that formation. 

 The statement requires authentication.
