as to the amount of material that is thrown up from the bed of sea 

 below low-water. 



It was admitted that much scouring takes place off shore and that 

 shingle travels below low- water mark. It was said to pass Beachy 

 Head on to Dungeness, and the opinion was even expressed that no 

 natural headland in the country completely arrests the travel of 

 shingle. 



On the other hand, it was asserted that stones in bays do not get out, 

 that the shingle was retained in compartments between headlands. 

 Here the Chesil Bank came in for discussion, and the old question was 

 revived whether the Budleigh Salterton pebbles, which form a small 

 portion of the material, came direct from the Devonshire cliffs, or 

 were derived from a former raised beach of which tiny remnants still 

 exist. Here it may be observed that no Budleigh pebbles are known 

 to occur in the Tertiary (Eocene) gravels. 



Incidentally other questions of geological interest arose, with regard 

 to the warp of the Humber, and " Is clay a mineral ? " 



Geological evidence on the waste of particular portions of the 

 coastline in England and Wales was given in order as follows, by 

 W. Whitaker, Clement Reid, H. B. Woodward, C. Fox-Strangways, 

 G. A. Lebour, A. Strahan, J. R. Ainsworth Davis, S. H. Reynolds, 

 E. H. Worth, T. Y. Holmes, and T. Mellard Reade (by Memorandum). 



We look forward with interest to further information on the 

 important subject of Coast Erosion, and to the conclusions at which 

 the members of the Royal Commission after their long and patient 

 labours will arrive.

 WE have received from the Board of Agriculture and Fisheries, 

 Whitehall, the above memoir, which has been prepared by the 

 Geological Survey of Ireland under the Department of Agriculture 

 and Technical Instruction for Ireland. It is the last of four memoirs, 

 the result of field-work carried out under the superintendence of 

 Mr. Lamplugh, prior to the severance of the Geological Survey of 

 Ireland from that of Great Britain. The preface is therefore written 

 conjointly by Dr. Teall and Professor Grenville Cole. 



The value of a detailed Drift map is amply shown in the colour- 

 printed sheet which accompanies this memoir. Nevertheless, it must 

 be admitted that in an area where the ' solid ' rocks appear only in 

 comparatively small and isolated tracts, it would be difficult to grasp- 

 the underground structure without the aid of the section at the foot 

 of the map, or without the earlier hand- coloured sheets on which the 

 ' solid ' rocks were distinctly shown. The section shows how the 

 dominant features of the country were pre-Glacial.
