260 REPORT— 1888. 



Section C. 



Mr. C. E. De Ranee, who represented this Section, referred to the 

 work of the three Committees which he had brought under the notice of 

 the Delegates on former occasions, viz. : (1) The Underground Water 

 Committee; (2) The Erratic Blocks Committee; and (3) The Sea Coasts 

 Erosion Committee.' 



The first of these Commitiees requires information as to the depth of 

 wells, the sections passed through, the height at which the water stands 

 before and after pumping, daily records of the height and chemical 

 analyses of the waters. 



The Erratic Bloclis Committee wants information as to the position, 

 size, and character of boulders of foreign origin that may occur in drift- 

 covered areas, and is anxious that the position of the same should be 

 noted on the one-inch map of the Ordnance Survey. 



The Sea-Coasts Erosion Committee, like the other two Committees, has 

 a printed form of inquiry, which can be obtained on application to Mr. 

 Topley. 



With reference to the work of this last Committee, Mr. Topley stated 

 that but little assistance had as yet been received from the local Societies. 

 The Natural History Society of the Isle of Man had undertaken to collect 

 information ; and all similar Societies in maritime counties might greatly 

 assist the Committee by local observation as to present changes, and by 

 researches as to past conditions of the coast. 



With respect to the work of the Erratic Blocks Committee, Professor 

 Meldola said that he had been authorised to state on behalf of the Man- 

 chester Geological Society that several members of that Society had been 

 interesting themselves in the distribution of boulders in their district, and 

 it was expected that their results would be available by the next meet- 

 ing of the Association. It was also mentioned that Mr. Adamson had 

 been rendering assistance to this Committee on behalf of the Yorkshire 

 Naturalists' Union. 



Mr. Ralph Richardson, as the representative of the Edinburgh Geolo- 

 gical Society, pointed out that Scotland had been omitted from the 

 localities dealt with by the Erratic Blocks Committee. He stated that 

 much work in this field had already been carried out under the auspices 

 of the Royal Society of Edinburgh, and he hoped the Committee would 

 be able to utilise their results. 



Earth-Tremor Committee. — Professor Lebour stated that since the last 

 meeting of the Conference the formation of a joint committee by Sections 

 ' A, C, and G had been agreed to, and the resolution forwarded to the 

 Committee of Recommendations. The resolution was the following : — 



' That Sir F. J. Bramwell, Mr. E. A. Cowper, Mr. G. J. Symons, 

 Professor G. H. Darwin, Professor Ewing, Mr. Isaac Roberts, Mr. Thomas 

 Gray, Dr. John Evans, Professor Lebour, Professor Prestwich, Professor 

 Hull, Professor Meldola, and Professor Judd be a Committee for the pur- 

 pose of considering the advisability and possibility of establishing in other 

 parts of the country observations upon the prevalence of earth-tremors, 

 similar to those now being made in Durham in connection with coal-mine 

 explosions, and that Professor G. A. Lebour be the Secretary.' 



Mr. De Ranee remarked that the proposed observations might possibly
