A HISTORY OF BEDFORDSHIRE 
Paleolithic flakes and mammalian remains have also been discovered 
at Round Green and Ramridge End one mile north-east of Luton. Other 
localities are Houghton Regis one mile north of Dunstable, Stanbridge 
Ford two miles west of Dunstable, near Sewell and near the source of the 
Ver at Markyate Street at the extreme south of the county. 
The more remarkable discoveries are those made by the writer in 
the brick-earth and contorted drift on the hilltops south of the county, 
chiefly at and near Caddington, between Dunstable and Luton. 
The gravel pits at Bedford, in which paleolithic implements and the 
bones of Pleistocene mammalia occur, rest on Oxford Clay and the Corn- 
brash, the upper portion of the Lower Oolite. Resting on the Oxford 
Clay and capping the adjoining hills is the Upper Chalky Boulder Clay. 
The valley has been excavated through the Boulder Clay and Oxford Clay, 
and the implement-bearing gravel contains materials derived from these 
deposits. No paleolithic implements occur in the two clays, and it is 
obvious that the deposits in the valley are later in age than the deposits on 
the hills which have been cut through and exposed in section on the 
hillsides. 
The valley gravel near Bedford is about 13 feet thick. It consists of 
subangular flints, yellow, ochreous and brown in colour ; oolitic debris ; 
pebbles of quartz and sandstone ; new red sandstone conglomerates, and 
other old rocks derived from the Boulder Clay or other glacial deposits. 
Its fluviatile character isshown by the numerous shells of land and fresh- 
water mollusca. 
Two implements from the Bedford gravels are illustrated in figs. 2 
and 3. A third, made from a large natural flake of flint, is shown in 
fig 4. One side of this implement, shown on the right, is plain, and, 
with the exception of one or two human touches, it is natural and covered 
with glacial striz. No strie occur on the portions worked by human
