From 90 to 165 feet the clay varied in nature, being 
alternately soft and hard; but, as will be seen in the section at 
170 to 175 feet, hard stone occurred, with, Ithink, some tough 
clay, which much retarded progress, and only 11 inches of work 
was done in the day—the 17th February. 
It was not until the 24th, when the boring was 200 feet, 
that the clay which came up was carefully examined. 
On the 2nd of March I became very anxious, as the depth 
had reached 223 feet, and I sent over a few small but imperfect 
shells to Dr Wriceut, with a piece of Pyrites, but he wrote to 
me that he was unable to give an opinion from such frag- 
mentary specimens. 
At 228 feet part of an Ammonite was found, followed by 
some broken Gryphwa incurva, and at 243 feet I took Mr Dr 
Rance, of the Geological Survey, who was at Gloucester about 
the supply of water which the Corporation proposed to take 
from Birdlip, but he could not throw any light upon the 
exact position of the beds. 
At 259 feet I confess I felt quite perplexed, and wrote to 
Dr Wricut, who kindly came over on the 14th March, by 
which day the boring had been sunk to 264 feet. 
We carefully examined the shells, which apparently were 
small Cardiums and Cerithiwms, and he thought the Avicula 
Contorta zone was reached. 
On the 28th, 288 feet depth, I was satisfied the boring was 
well in the Rhetic Beds. Dr,Wricur came over on the 30th, 
depth 294 feet, and, from the spoil and small shells, we were 
both of opinion that the boring was well in the Rhetie. 
When I visited the work on the 17th of April, on looking 
at the spoil and the shells found, I was much surprised: 
instead of the beds being Rhetic, they appeared to me to be 
the lower beds of the Bucklandi zone. 
Dr Wricut came again on the 21st April, the depth then 
being 341 feet; and he was of opinion the boring was in the 
Bucklandi beds, or might be in even the Turneri. 
The boring had reached 350} feet on tae 28th April, when 
it was stopped.
