mile wide. The peat reaches a depth of 8 feet, and in wet weather 
the whole area is under water. The glacial ridge to the S.S.E. 
rises steeply above it, and must sink as steeply underneath. 
Probably the depth of the hollow, as well as its distance from the 
river, prevented the brick-eaiths from filling it up. 
Two or three patches of peat also occur at the river level, 
perhaps indicating previous channels, like the bayons of the 
Mississippi. Both upon Clifton Ings and below Clementhorpe it 
is interesting to note that the river meadows sink away from the 
river, so that they are drained by small sluggish becks running 
parallel to the main stream. Another patch lies close by Ouse 
Bridge, under Brett's Brewery, the managers of which I have to 
thank for the following section obtained in their well : — 
1 . Soft warp, with sand ... . 
2. Blue clay, (perhaps like the local brick clays) 
3. Fine sand 
4. Soft bog, and stone boulders 
5. Dark yellow soft clay 
6. Very loose gravel and pebbles, with water 
7- Very fine sand ... 
8 & 9. Not given 
10. Soft brown free stone ... 
11. Very soft and open gravel bed 
12. Sample (sic), blue free stone ... 
13. Soft blue and yellow clay, mixed 
14. Brown free stone 
15. Rock blue stone and soft sand 
16. Brown iron stone, left off in stone . . .

The River and Brick-earth beds, very remarkably, lie under 
40 feet of sand and clay deposits, and have been regarded as 
inter -glacial, but I have not seen any adequate proof for such an 
inference. That the river deposits are in many parts very deep 
was well shown by the nine borings and excavations when the
