Mr. Hanpet CossHam read a short paper on “The Pennant 
Formation in relation to the Bristol Coal-field,” in which he 
remarked that the “Pennant” forms one of the best proofs we 
possess that the Welsh Coal-field, that of the Forest of Dean, 
and that of Bristol, are all members of the same family, and 
were all formed at one period; that all at one time formed one 
great basin, which time and geological changes have severed 
into three distinct Coal-fields. These changes have been 
mainly due to the rent or “fault” now occupied by the river 
and estuary of the Severn, which has not only separated the 
Bristol area from that of Dean Forest and South Wales, but 
has given to it a lateral thrust, which has caused the dislocations 
which render the Bristol Coal-field so difficult to work. 
Lastly a very interesting and instructive paper was read by 
Mr. Jounson, the superintendent of the pits, ‘‘On Compressed 
Air, and its application to Mining.” 
The thanks of the Club were voted to Mr. Cossnam for 
having so successfully planned and carried out a most enjoyable 
Field Meeting, and to Mr. Jounson for his paper; after which 
the party broke up and dispersed. 
The first Winter Meeting of the Club was held in the Lecture 
Theatre of the 
SCIENCE SCHOOL IN GLOUCESTER, 
on Wednesday, 9th of February, in the present year, when a 
paper was read by Mr. Wrrcnett, of Stroud, on the ‘ Pree- 
Cambrian Rocks of St. David’s.’ Those who read—and what 
Geologist does not?—The Quarterly Journal of the Geological 
Society, will have enjoyed the advantage of studying the series 
of rocks under consideration, in the memoirs of Dr. Hicks, a 
local Geologist, to whose researches is due the separation and 
classification of this area of obscure and little-known rocks. 
Mr. WircueEtt had lately had the advantage of traversing the 
ground in company with Dr. Hicks, and it was with the desire 
of introducing to the notice of the Cotteswold Club the nature 
and sequence of these rocks that Mr. WircHeEtt read his paper, 
which was well illustrated by maps and diagrams.
