HARMER : FIELD EXCURSION TO CROMER, ETC. 309 
beds of the same age in the North of England." As introductory 
to this, the following pa23er (see page 315) was read, and followed 
by a discussion, in which Prof. Kendall, the Rev. W. Lower 
Carter, and others took part. 
Following the programme agreed on, the party left Cromer 
on the morning of Saturday, July 11th, for Norwich, making 
their headquarters there at the Royal Hotel. 
An important series of sections were first visited near to 
a road gradually rising northwards from the city towards Sprows- 
ton, Catton, and Hellesdon. 
The lowest of these (PI. XLIV.) showed the Crag sands, here 
unfossiliferous, resting on the unglaciated surface of the Chalk, 
and overlain by pebbly gravel. In another pit (PI. XLV.), at 
a somewhat higher level than the last, the sandy brickearths of 
the Lower Glacial series, into which the Contorted Drift of the 
coast passes horizontally inland, were observed to be overlain 
in section by the Middle Glacial sands. These brickearths 
give slight but unmistakeable evidence of ice action, indicating 
probably that it was becoming feeble and dying out in this 
direction.* At Hellesdon brickyard, belonging to Mr. Alderman 
Cunnell, of Norwich, f some small boulders of Shap granite and 
rhomb-porphyry, identified by Prof. Kendall, were noted. 
At a somewhat higher level, a section of the " Cannon 
Shot " gravels, which are largely developed on Mousehold Heath, 
to the north of the city (PL XLVL), was visited. Although the 
Chalky Boulder-clay is absent from this section there is little 
doubt that these gravels are newer than that deposit. In 
many other places, indeed, they rest upon it. They are possibly 
* It should be specially noticed that the slight contortions observed 
in the Lower Glacial brickearths of this spot, which are hardly to be seen 
in the photograph (PI. XLV.), were anterior to the deposition of the over- 
lying Middle Glacial sands. The latter are quite iindisturbed and rest 
on the former with an even line. 
t Our thanks are due to Alderman Cimnell for permission to examine 
his extensive quarries, and for his kind hospitality on the occasion of 
our visit.
