854 REPOKT— 1886. 



data are chiefly confined to work on the geology of the coast, Sec. e. Yes ; for 

 on the north side of Cromer the loss is comparatively small, which is no doubt 

 due to the large beds of shingle which occur from Cromer through East Runton, 

 West Eunton, Beeston, Sherringham, and Weybourn, where the cliffs end and 

 are replaced by large beds of stones. 

 ISi Yes, at Cromer a bed of shingle is of rare occurrence, for as soon as it is seen it 

 is carted away. a. Yes. b. I do not think that the groynes stop the shingle, 

 for as soon as they are full on the north side it washes over the top and so 

 travels along. 



16. a. No, only now on the Lincolnshire coast. 



17. Only at Hasbro', where they replace the cliffs and extend up to Yarmouth. 



a. Marram Hills, so called from the species of grass which grows upon them 

 and binds the locse sand together, d. I believe they increase near Yarmouth, 

 as the water is gradually receding at that place, e. They very rarely shift, and 

 are kept in tlieir jDlaces by the marram grass. 



7. Weybourn to Palling. 



By Clement Reid, Geological Survey Office, 28 Jermyn Street, London. 



1. Norfolk, between Weybourn and Palling (23 miles). 



2. Cliffy, except about three miles of alluvium protected by sand dunes, a. Boulder 



clay and gravel, but for four miles near Weybourn the base of the cliff is 

 chalk (soft, with many flints), b. (1) 250 feet. (2) 80 feet. (3) or 3 or 4 

 feet below high water at Hempstead Marshes. 



3. E. and W. at Weybourn, but curving near Cromer to the E.S.E., which direction 



it retains for 16 miles of the distance. 



ft. South-west. 



5. a. N.E. to N.N.W. b. Gentle southerly or south-westerly, c. N.N.W. 



6> Flood tide strong, close in sliore, from the N.N.W. Ebb weaker and in the op- 

 posite direction. At Cromer there is about three hours' difference between the 

 time of high water and the change in the direction of the current. 



7. (1) 18 or 19 feet at spring tides. 



8. For about 8 miles there is a foreshore of chalk, more or less covered with shifting 



sand and banks of loose unworn flints. The rest of the coast has a foreshore 

 of sand, generally resting on clay. Everywhere there is a shingle beach ex- 

 tending from above high water to about the level of mean tide. The beach 

 becomes more sandy southward. 



9. a. Constantly varying according to the direction of the wind and the denudation 



of the coast, b. Between mean tide and extreme high water, c. To the E. 

 and E.S.E. d. "Very various ; they^ are stones washed out of the boulder 

 clay. e. Usually in one continuous slope, but varies with the wind. 

 lO. Constantly shifting, and moving back with the denudation of the cliff, but no- 

 where greatly accumulating or diminishing. 



12. f. Prevent the beach travelhng to the S.E. j\\B. — Under the higher cliffs the 



old groynes have been crushed by landslips, and it is useless to erect fresh 

 ones unless the cliffs are sloped at a very low angle ; the cliffs are full of land- 

 springs, 



13. Only at Cromer and Runton. a. Large flints are taken, principally from the 



lower part of the beach, b. and c. Building (private individuals), road- 

 making (local authorities), and pottery (companies). The amount removed 

 has as yet been too small to make any appreciable difference, especiallj- as it 

 is immediately replaced. 



1ft. Yes. a. Along the whole coast, b. See 2. e. About 2 yards annually, d. See 

 Redman's paper on the ' East Coast.' e. No. 



15. Yes. a. No. b. At Shcrringham there is a short space bare of beach beneath 

 the new groyne, and the cliff has been denuded much faster, east of the village, 

 since the groyne was erected. The erection of groynes at Cromer caused the 

 clay foreshore and base of the cliff to be exposed for many years at OTcrstrand, 

 but the denudation of the clay has now allowed a new beach to form, adjusted
