Norwood, and associated Eolithic Implements. 15 
sandy loam. Midway between the two was a peculiar patch of 
pinkish-coloured loam with rounded pebbles.” (I may say I did 
not closely watch this trench three years ago, but my recollection 
of it was that it did not exceed three feet in depth.) 
Mr. Martin further remarks upon the sand and gravel near 
Upper Beulah Hill, which, he states, ‘‘resembled Croydon gravel,” 
and near the house ‘St. Ives’ ‘‘ contained a large number of 
rounded flint pebbles.” I am sorry Mr. Martin did not record 
the character of the gravel and its constituents more particularly, 
as this seems to me to be the most important matter respecting this 
isolated sheet of gravel. 
I have endeavoured to find other records respecting this gravel, 
but they seem to be very meagre, though there must have been 
many sections exposed when the houses from South Norwood 
Hill to Westow Hill were built; but at that time there was 
unfortunately not the same interest felt in gravels as there has 
been since it was discovered that many in the South of England 
contained flints bearing evidence of human workmanship. 
I know of no recorded finds of implements from this patch of 
gravel. 
Mr. Whitaker, in his ‘Memoir on the Geology of the London 
Basin,’ 1889, vol. i. p. 883, referring to Mr. F. J. Spurrell, 
says :—‘‘ The gravels of the Norwood hills are referred to as the 
highest of the old Wandle, but it seems possible, if these are 
River Gravel, they may belong rather to the old Thames.” Later 
(p. 427) :—“ Besides this [the gravel at Wandsworth Common] 
the only high isolated patches are at Clapham and at Balham, 
besides the still higher ones df Lower and Upper Norwood, as to 
the classification of which there may be some doubt, especially 
with the highest and most southern.” 
It must be borne in mind that we are dealing with a very high 
gravel, the altitude of this patch being from 350 to 380 ft. above 
O.D., or about 200 ft. above the highest terrace of Wandle gravel at 
Croydon or Thornton Heath, and about the same height above 
the Thames as the gravels at Wandsworth or Clapham. 
The only other high patches of drift anywhere near Norwood 
are those at Shooter’s Hill to the east and Wimbledon Common 
to the west, both at a considerable distance, with the still more 
distant patches at Telegraph Hill, Swanscombe and Dartford 
Heath to the east, and Kingston Hill to the west. 
The fullest reference that I can find to the gravel under our 
notice is that made by Prestwich in his communication to the 
Geological Society, ‘‘ On a Southern Drift in the Thames Valley, 
and its Relation to the Westleton Beds,” &¢.* This gravel is 
there referred to as follows :— ;
