the clay has been dug*. The old workers had commenced 
near the village of Hoxne, and as they gradually exhausted 
the clay up to the road they moved further southward, and 
the point at which it is now excavated is probably at least a 
quarter of a mile distant from that where Mr. Frere made 
his discoveries in 1800. The pit has now been worked up 
to some farm buildings that interfere with its progress 
southward, and to get clay they have now crossed the road 
into the park, and thus made a most important addition to 
the sedtion laid open. 
I have in the accompanying plate given three sections of 
the ground. The first shows the theoretical relation of the 
beds according to Prof. Prestwich. The second exhibits the 
fadts adtually observed by Prof. Prestwich and myself; and 
the third is a theoretical sedtion, showing the relation that 
the beds hold to each other according to my own views. 
We shall in the first place confine our attention to the 
second sedtion, Fig. 4, showing the fadts adtually observed.

Fig. 6,— x..“ Trail,” 3 feet. 6' and 6, Boulder clay, chalky in upper part. A slight line 
of division between it and the lower part, which is principally composed of crushed 
Kimmeridge clay with pieces of chalk. 
On the east side of Gold Brook a cutting has been made 
into the bank, and a thick bed of boulder clay is exposed. 
At the point A in general sedtion the beds are shown as in 
Fig. 6. Near the line of division the upper and more chalky 
clay contains many large flints and transported boulders. 
Some of these are smoothed, and strongly scratched and 
grooved. Two scratched blocks of septaria that I saw 
measured feet across. This boulder clay, both in its 
upper and lower division, is very distinct in appearance and 
composition from that lying above the gravels as seen in 
other sedtions. Lower down towards the brook a seam of 
false-bedded sandy gravel comes in between the boulder clay 
and the “ trail,” and represents, I think, the gravels of 
Figs, i and 2. 
Crossing the brook and ascending the opposite slope, we
