THE WEST OF ENGLAND AND EAST OF WALLS. 443 
the hill, which Mr. Maw%*, F.G.S., tells me is 800 feet above the 
sea-level. Here the gravel, which is unstratified, is probably on the 
horizon of the Lower Boulder-clay of Cheshire and Lancashire. 
Numerous rounded pebbles of Eskdale granite are found along with 
Lake-district felstone in the gravel-pit, and many large boulders 
have been dug out of ity. A very few Criffel-granite boulders are 
mixed with the others around Burton; and the reason why both 
are conterminous would appear to be the persistence (fur a time) of 
a local obstruction, probably consisting of the two abruptly rising 
ridges of Ludlow rocks (between which Burton village is situated), 
at a time when the land had been submerged to a depth of between 
800 and 900 feet, in which case the few Criffel boulders may have 
arrived before or after the Eskdale precipitation. There are Eskdale- 
granite stragglers east of Burton, one at Callaughton, 34 x 2 x 2 feet, 
and one, if not more, in Much Wenlock. West of Burton I saw a 
very few stragglers around Cardington, Gretton, and Enchmarsh, and 
one in Church Stretton. Inquirers may be benefited by knowing 
that around Burton boulders are called ‘‘ pimples.” 
8. Supplementary Dispersion of Eskdale- and Criffel-Granite 
Pebbles along the lower part of the Severn Valley.—South of Bridge- 
north, at least as far as the somewhat elevated ground about Sutton 
(west of Hampton-Loade railway-station), many pebbles of Eskdale 
and a few of Criffel granite may be found. Further south they 
gradually disappear, excepting in the immediate neighbourhood of 
the river Severn. About Bewdley they are only to be found in or 
close to the river-channel; and I have reason to believe that this is 
the case the whole way south as far as they extend, with a very few 
exceptions, in which stragglers (probably belonging to the great 
Criffel boulder-dispersion) may have been carried by floating ice. 
An instance of this occurs on the summit of a knoll, 150 feet above 
the Severn, at Apperley Court (about halfway between Tewkesbury 
and Gloucester), where, in a “rockery,” there are several small 
boulders which were found close by, and which, after many attempts 
at identification, I believe may be South-Scottish granite. If so, 
they must have been transported about 220 milest. But with this 
and possibly a few other exceptions, the granite pebbles south of 
Bewdley are confined to low levels bordering the channel of the 
river. They may have been transported by the river during shallow 
estuarine conditions after floating ice had entirely, or almost entirely, 
disappeared; or the transportation may have occurred during a 
southerly extension of the Upper Boulder-clay submergence through 
the Ironbridge gap. During my rambles with the Rev. W. 8. 
Symonds (whose kindness it would be difficult for me to repay) I 
* Mr. Maw first discovered this group of boulders, but did not specify the 
kinds of granite. 
+ Between the grayel-pit and the village I saw a part of a boulder of felspa- 
thic breccia 4X23 x1 foot, the rest of which had been blasted. JI was unable 
to identify a few of the more or less felspathic boulders, but none of them were 
of the Arenig type. 
¢ My attention was directed to these boulders by the Rey. W. 8, Symonds.
