12 YORKSHIRE NATURALISTS' UNION ANNUAL REPORT FOR I 893. 



Kirkby Moorsicle afforded an interesting centre for the study of 

 the Yorkshire OoHtes. (lood collections of fossils were obtained by 

 some of the members. 



The fourth excursion was along the valley of the Ribble, from 

 Sawley Abbey to Gisburn, imder the leadershi]) of Mr. R. H. 



Some interesting sections of contorted 



Tiddeman, M.A., F.G.S. 



Carboniferous T>imestone were seen. 



The turn of the Cretaceous beds came at the final excursion to 

 Pocklington, when interesting sections of the junction between 

 the Upper Lias and the Upper Cretaceous beds were seen ; the 

 whole of the intermediate beds being absent in this area owing 

 to excessive denudation. 



The Committees of Research liave continued their investi- 

 gations during the year with more or less satisfactory results, and 

 have thoroughly maintained the reputation which the Union enjoys 

 as a distinctively working body. 



The Committee for collecting and recording Geological Photo- 

 graphs, of which Mr. James E. Bedford, F.G.S. , is the Secretary, has 

 worked with its usual success, and a fair number of photographs have 

 been taken. Many of them are of particular value as they refer 

 to Sections which cannot again be photographed, such as fossil 

 trees laid bare in quarrying and excavations for the foundations of 

 buildings, etc. 



The Yorkshire Boulder Committee still continues to hold 

 a prominent place in the British Association Committee's report. 

 The Secretary, Mr. Thomas Tate, reports tliat during this year the 

 investigation of the main valley of the Calder has received special 

 attention and has been prosecuted with vigour. The new Boulder 



Map of the County on the one-inch scale has been mounted, and the 

 map[)ing of all recorded Erratics thereon is in progress. The 

 Committee are now giving their attention to the area around 

 Barnsley, upon which they hope to report next year, and they will 

 welcome any local help tliat is available. 



The Yorkshire Fossil Flora Committee. — Part i8 of the Transac- 

 tions of the Yorkshire Naturalists' Union, which appeared this year, 

 is devoted to the report on the ' Yorkshire Carboniferous Flora,' by 

 Mr. Robert Kidston, F.R.S.E., F.G.S. , on behalf of the above 

 Committee. 



The Coast Erosion Committee. — The work of this Committee 

 during the year consists principally of measurements, taken by the 

 Secretary (the Rev. E. Maule Cole). Mr. J. Coventry FAnson also 

 has forwarded a plan showing the position of the foot of the l^oulder 

 Clay Cliff for half a mile between Saltburn-by4he-Sea and Marske,
