THE WEST OF ENGLAND AND EAST OF WALES. 445 
a quarter of a mile south-east of Chirk bridge another 13 x 7 x 3 feet 
above ground. Between Chirk, Gobowen, Whittington, and Welsh 
Frankton (near Ellesmere) there are many Arenig boulders. West 
of Welsh Frankton, close to where the road crosses a canal, there 
are 8x8 feet of an Arenig boulder above ground. One close to 
Mr. Oswell’s house, Welsh Frankton, is quite 8 feet in average 
diameter. Another, a few yards distant, is 85x6x5 feet. They 
are accompanied by good-sized boulders of Silurian grit and Car- 
boniferous sandstone and quartzite from the Welsh borders. In 
the neighbourhood there are many large and small Arenig boulders ; 
and they may be found as far east at least as Ellesmere, accompanied 
by Mountain Limestone and Millstone Grit from the Welsh borders. 
It would thus appear that the Arenig dispersion must have cleared 
the Welsh mountains in the neighbourhood of Llangollen, and partly 
crossed the southerly course of the Eskdale granite over the Shrop- 
shire plain. 
3. Overshot Boulders around the Clent and Lickey Hulls ( probably 
Aremg).—South-east of Welsh Frankton I have not had time to look 
for a continuation of the Arenig dispersion; it may possibly exist 
under a covering of upper clay. Between Wellington and Wroxeter 
saw afewsmall Arenig-looking boulders ; but between Bridgenorth 
and Wolverhampton there seemed to be few or none of them, though 
this would most likely be their course to the Clent and Lickey hills, 
around which many large felstone boulders have been brought to 
light through the diligent efforts of the Rey. H. W. Crosskey, F.G.S., 
Secretary of the British-Association Erratic-Block Committee. I 
examined these boulders, chiefly between Catshill and Hagley *, in 
a district which seemed to be totally exempt from granite erratics. 
This fact, combined with the size, shape, and appearance of the 
surface of the boulders, supplemented by a comparison of specimens, 
led me to adopt the opinion that they must have come all the way 
from the great Arenig mountain or the neighbourhood. My acquaint- 
ance with the country about Llanymynech, Church Stretton, Burton 
(Shropshire), Much Wenlock, &c. convinced me that the boulders 
could not have come over the Welsh mountains from the Arenig 
mountain along a route further south than the mouth of the Llan- 
gollen and Ceiriog valleys; and the discovery of an extension as far 
as Welsh Frankton and Ellesmere of the Arenig dispersion over the 
Shropshire plain confirmed the idea that this was the route the 
boulders must have taken. The absence of a serics of connecting 
links between Welsh Frankton and the district around the Clent and 
Lickey hills may be explained by supposing that the ice which 
carried the boulders over the lesser Welsh cminences was sufficient 
to float them as far south as the above district. These boulders, 
therefore, may be regarded as an overshot load (or a series of over- 
shot loads) that is shot over the great Criffel terminal concentra- 
* J afterwards could not find any as far south as the latitude of Droitwich. 
+ Similar boulders have been found around Birmingham, including the great 
Cannon-park boulder, and it is probable that they likewise came from the 
Arenig area,
