XIII.—On tue Occurrence oF BourpEers oF STRONTIA IN THE UPPER 
Triassic Marts or ABpots Lricu, near Bristot.! By Hexserr 
Borron, F.R.S.E., F.G.8. 
CONSIDERABLE area of the park attached to Leigh Court, near 
i\ Bristol, has been found to be underlaid by a remarkable deposit 
of huge boulders of strontia embedded in Triassic marls. The boulders 
in various places appear above the surface. The soil varies in depth 
from a few inches to 4 feet, and rests upon the irregular surface of 
the marl-beds containing strontia. The boulders of strontia are found 
of all sizes, from a pea up to masses estimated at 100 tons in weight. 
In one instance the breaking-up of a single boulder of strontia 
occupied six men for five weeks. Six hundred tons of the mineral 
were found in one pit, 15 yards long by 21 yards wide. 
The upper surface of the boulders is usually deeply grooved, the 
grooves running approximately north and south. The boulders readily 
split into slabs along lines coinciding with the grooves. The deposit 
up to the present has not exceeded a greater depth than 11 feet. The 
yield of strontia is about 2,000 tons per acre. 
XIV.—InvestTigation oF THE FossttrFerous Drirr Deposits at 
Koruineton, LinconnsHirE, AND AT VARIOUS LOCALITIES IN THE 
East Rivine or Yorxsuire.? By J. W. Sraruer, F.G.S. 
S was intimated in our report for 1905, the work during the past 
year has been directed to the inyestigation of the deposit at 
Bielsbeck, or Bealsbeck, in the Vale of York, which was examined 
between seventy and eighty years ago by the Rev. W. V. Harcourt, 
and yielded the remains of numerous extinct mammals. The object 
of our investigation was mainly to ascertain if any further evidence 
could be obtained to show the relation of this fossiliferous deposit to 
the glacial drifts. 
The work, which was carried out under the superintendence of 
Professor P. F. Kendall, Messrs. G. W. B. Macturk, Thomas Sheppard, 
and the Secretary, confirmed the statements of the previous observers : 
(1) that the deposits yielding the bones rested immediately on the 
Keuper Marl; (2) that they have been accumulated in a boggy hollow 
on an old land surface; and (3) that at this particular locality there 
is no material that can be assigned to the direct agency of ice. It 
therefore still remains a debatable question whether the bone-bearing 
material was accumulated before, during, or since the Glacial period ; 
and it would appear that the elucidation of this matter will depend 
upon the investigation of a wide area to determine what was the 
condition of the Vale of York during that period.
