THE GEOLOGIST. 
blocks^ if they were gifted with speech, would tell of events 
long past, — perhaps of the action of mighty streams which once 
swept over them, or it may be of enormous icebergs, which 
conveyed them from remote regions tO' — puzzle posterity. 
Before all traces of these boulders are lost for ever, it v/ould 
be well that their position should be accurately noted down,"^ 
their probable weight, the degrees in which they are rounded 
by attrition or other causes, and the nature of the beds in 
which they are associated: — these observations should be 
attached to a fair specimen of each mass, and deposited in 
your Museum. By degrees a sufBcient body of information 
may be obtained to show the path in v/hich they have steered, 
and eventually their original localities. Connected with this 
subject your Committee would call your attention to the 
deposits of lias fossils found in the new red sandstone of 
Compton and Wightwick, which have apparently been there 
deposited by a tidal stream ; — how great is now the change ! 
Formations and cuttings in the nev/ red sandstone, and 
sections of the various sinkings for water in the town of Wol- 
verhamjDton, would be useful documents in the archives of 
your Society : these are easy of access to some individuals, 
who probably are not aware of their ulterior value. 
Another subject which might profitably engage your atten- 
tion, is the limestone formation more immediately connected 
with thp Wolverhampton coal field. The upper or Ludlow 
rocks of the series possess the property of setting under water, 
and are well developed at Sedgley Beacon, and on the west 
side of the road leading from Wolverhampton to Sedgley. 
These rocks have been but little examined ; — the fossils are 
not so numerous as those belonging to the Wenlock and 
Dudley rocks, but perfect specimens are far more rare. This 
* These boulders arc noticed in Murcliisou's map, but merely as occurring in 
(he neiglibourhood of TrysuU and Paltingham.
