AVEYBOURN CRAG.

Mill, near Honing. The shells collected at Honing by Mr. H. B. 
Woodward were:— 
Littorina littorea. 
Turritella sp. 
Astarte borealis. 
Cardium edule. 
Corbula gibba. 
Cyprina islandica. 
Mya arenaria. 
Nucula 0obboldia3. 
Tellina balthica. 
-sp. 
Balanus sp. 
Foraminitera. 
On the Norfolk coast, attempts were made to reach the beds 
underlying the Glacial Deposits near Eccles, but without success. 
About seventy yards south of the old tower of Eccles Clmrch, a 
trial-boring made on the foreshore at half-tide level reached a 
depth of 12 feet, without penetrating the Till, and was then 
stopped by the rising tide. Another boring exactly opposite 
Happisburgh Church was more successful, for commencing below 
high-water level it reached a depth of 22 feet. The section 
was :—

No fossils were observed, but numerous grains of glauconite (!) 
and small particles of carbonaceous matter occurred in the lowest 
beds. 
The eighteen feet of micaceous clays here found beneath, the 
Eorest-bed are so exactly like the Ohillesford Clay of other 
localities, and hold so similar a position, that it is difficult to avoid 
referring them to the same horizon. But if we do so we must 
also consider the Ohillesford Clay to be the equivalent of the 
Weybourn Crag; for as we shall show, there is little doubt of the 
continuity of the clays of Happisburgh with the shelly Crag to 
the north-west, the beds becoming more sandy and fossiliferous 
when traced in that direction. 
At Mundesley the same clays were reached, for a boring on 
the foreshore about 200 yards south-east of the stream showed :— 
Forest-bed.

This trial-boring was commenced at half-tide level, the hard 
ferruginous gravel of the base of the Forest-bed being used as a 
convenient firm platform to work on. Immediately below this 
the character of the deposits suddenly changed, from coarse 
gravelly sands and carbonaceous clays, to fine-grained micaceous 
beds entirely without stones. The rods unfortunately parted at 
22 feet, owing to the constant closing up of the hole through the 
softness of the clays, but the last sample brought up showed a 
single small fragment of shell, perhaps indicating the commence¬ 
ment of the shelly beds met with at Trimingham.
