THE WEST OF ENGLAND AND EAST OF WALES. 447 
shire. Mr. Woodward (of Birmingham) found chalk-flints and spe- 
cimens of Gryphea incurva at Lillieshall (east cf Wellington), which 
probably came from the east. Mr. Maw, F.G.S., found chalk-flints, 
bits of hard chalk, fragments of Oolite, and Lias fossils at Strethill, 
near Ironbridge, which probably came from the east, as similar 
erratics can be traced in an easterly direction. I found a chall-flint 
at Seisdon (between Wolverhampton and Bridgenorth); and many 
chalk-flints along with specimens of Gryphewa have been found in 
.the clay-pits around Wolverhampton. All these eastern erratics 
must have crossed the cowrse of the northern boulders near its 
southerly termination; and as both are found associated in the 
same drift-deposit, it seems impossible to explain the intercrossing 
by land-ice or glaciers. I found a number of chalk-flints in the 
Ashflat clay-pits (south of Stafford) and near Bushbury, which must 
have come from the east, because they thin out westward, and they 
are there associated with northern granite- and felstone-boulders. 
South of Wolverhampton and west of the Dudley and Clent 
hills the Bunter-pebble drift has not been much mixed with 
chalk-tlints. I could see none about Kidderminster and Droitwich, 
notwithstanding that in the latter town enormous quantities of 
gravel had just been thrown out of excavations for drains and 
house-sites ; but I have been assured that they are not entirely 
absent. South of Worcester a considerable number have crossed 
the general course of the Bunter-pebble drift as far west as 
Malvern*. The Rey. W. 8. Symonds has found chalk-flints as far 
west as Hafield Camp, south of Ledbury! ‘They have not only 
crossed the course of the southerly extension of the Bunter-pebble 
drift, but likewise the south-easterly course of the angular erratics 
from the Malvern hills. As most, if not all, of the chalk-flints in the 
west-midland counties would appear to have come from Lincolnshire, 
their general course must have been south-west.

OF THE BovuLDER-STREWN AREA. 
1. Statement of Facts—Away from the Welsh hills no decided 
instance of a striated rock-surface has yet been met with south of 
the peninsula of Wirral}, and they are almost entirely confined to 
the extreme northern part of that peninsula. Many of the rocks fur- 
ther south are of much the same kind, and equally adapted to receive 
and retain ice-marks. It may likewise be remarked that similar 
exposures of rock-surfaces by the removal of drift are of frequent 
occurrence. ‘To suppose that the Wirral striated rock-surfaces were 
* There must, then, have been a current from the north-east sufficiently cold 
not to melt the straggling ice by which the flints were transported. 
+ I lately stumbled on an instance of somewhat doubtful strize on Haughmond 
hill (near Shrewsbury), a short distance east of Haughmond Abbey, on the side 
of an old quarry just beyond a quarry now worked at the termination of the 
central greenstone protrusion. ‘The directicn was about north-west and south- 
east. If real striae, they may have teen made by ice-borne boulders from North 
Wales.
