COKRESrO^DlNU SOCIKTIKS. 25 



Mr. M. H. Mills thought that earth -tremors was one of the subjects 

 in which members of the Federated Institute of Mining Engineers could 

 assist. 



Mr. Symons inquired if it would be possible to place instruments- 

 underground at a depth of 100 feet. 



Mr. Mills did not think there would be any difiGculty. 



Mr. Mark Stirrup said that some mining engineers thought that ft 

 would be useless to place apparatus in mines because of the vibration 

 caused by the workings. 



Mr. Symons said that fortunately no difficulty would arise from that 

 cause, as the instruments, though extremely delicate, were not sensitive 

 to vibrations of short period. 



Mr. Kenward thought that he knew of a colliery in which instruments 

 could be placed. 



Section C. 



Mr. A. S. Reid said he had been asked by the Sectional Committee 

 to make some remarks. The Underground Waters Committee would 

 present their final Report next year, and would be glad to receive further 

 information up to the date of publication. The Geological Photographs 

 Committee thought that the size of photographs should be left to the 

 donors. As to the best camera further comments from practical 

 photographers were invited ; also remarks as to the best methods of 

 printing. With regard to publication, negotiations respecting the pro- 

 posed album of i-epresentative photographs were then in progress. 

 The Erratic Blocks Committee had presented a Report, and they were 

 going to publish as much as they could as soon as possible. The Coast 

 Erosion Committee had not sent in a Report, though they had plenty of 

 material in hand. The Committee on Type Specimens in Museums were 

 making arrangements for the i-egistration of those specimens, and in- 

 formation was required as to where they were housed. 



Mr. Tate inquired, with regard to geological photographs, if smali 

 photographs taken with a good lens were not preferred. 



Mr. Reid replied that the Committee were i-eady to receive any good 

 photographs. 



Section D. 



Protection of Wild Birds' Eggs. — Mr. Slater thought it was high time 

 something was done to protect the eggs of wild birds. Influence might 

 be brought to bear upon boys. Ho also deprecated the wanton shooting 

 of gulls. 



The Chairman stated that the Committee had been reappointed, and 

 that the delegates would in due time receive a final communication on 

 the question. 



Mr. C. H. Torr (Nottingham) said that a valuable suggestion had 

 been made that County Councils, and through them Board schools, 

 should put up notices during the season asking boys not to take eggs. It 

 was of little use to talk of legislation, as the eggs would be gone before 

 it could be obtained. 



The Chairman remarked that at Edinburgh much had been said 

 about the number of rare eggs in the possession of collectors.
