other, to the Boulder Clay, and to the surrounding district*.

Traces, but somewhat indistinct, of Loess exist on the gravel d, and on the slopes of the valley.

The dotted lines here and in the other sections show the presumed old surfaces. 
The higher valley deposits assume in the tributary valley of the Gold Stream at 
Hoxne a more lacustrine character. The lower-level gravels may be seen in the field 
opposite the Swan Inn, overlying the sand and gravel of the Boulder Clay series. 
Valleys of the Ouse and Larkf . — In the main valley of the Ouse at Bedford eight 
flint implements have been found under circumstances which admit of no doubt of their 
geological position ; and at Icklingham in the valley of the Lark, a tributary of the same 
river, two specimens have been met with, which, although not discovered in situ , there 
is good reason to believe came from the high-level gravel J. In descending the valley 
of the Lark, from Bury St. Edmunds to Icklingham, Mr. Evans and I found it flanked 
by low ridges of gravel rising from 20 to 30 feet above the valley, and these again com- 
manded by higher ground formed of the Boulder Clay. In a pit at Flempton I found 
in the gravel a fragment of bone, and remains of the Elephant have been met with at 
various places near Bury St. Edmunds ; but we saw no traces of shells in any of the drift- 
gravels or sands of this district. The section of the valley is as follows : — 
a. Becent alluvial deposits. c. Low-level gravel. d. High-level gravel. (Only traces of Loess.) 
1. Boulder Clay. 2. Sands and gravel under the Boulder Clay. 3. Chalk. 
In the valley of the Ouse at Bedford (see fig. 3) I have been unable to detect at 
* The scale of height in these and all the following river-valley sections is 1 inch to 400 feet. In the hori- 
zontal scale 1 inch equals about | a mile (except figs. 4 & 5). The base-line gives the sea-level approximately. 
t I originally made a section of the valley of the Ouse at Bedford in 1854, and then determined the relation 
which the well-known mammaliferous gravel of this valley bore to the adjacent Boulder Clay. The number 
of fossil hones subsequently discovered in the cutting of the Great Northern Hallway, led Mr. Evans and my- 
self at once to direct our attention to this valley on our return from the valley of the Somme in 1859. The 
discovery, by Mr. Evans, of fluviatile shells in the Biddenham gravel confirmed the analogy we suspected, and 
we directed Mr. Wyatt’s attention to it and to the probable occurrence of flint implements, in the search for 
which this gentleman has since been so successful. 27 specimens are now recorded by Mr. Wyatt. — Feb. 1864.
