GEOLOGICAL SECTION. 



The Secretaries report that the excursions have afforded the 

 geologists opportunities of examining almost the whole sequence 

 of the rocks exposed in Yorkshire. The section has been well 

 represented on each occasion, and much useful work has been 

 done. At Market Weighton the interesting junction of the Lias 

 and Red Chalk was examined. In Bowland the week-end was 

 very profitably spent in collecting fossils from the Lower Car- 

 boniferous rocks, and furthering the work of zoning these rocks. 

 Runswick Bay, with its fine exposures of Liassic and Lower 

 Oolitic strata, in chff and scar, attracted many members. The 

 phenomena connected with the drift-filled old valley also received 

 attention, and many erratic boulders were noted. The study of 

 the pre-Carboniferous rocks of the county, and their relationship 

 to the Carboniferops formation, commenced at Ingleton, and 

 continued in successive years at Horton and Clapham, was con- 

 cluded at Sedbergh. A good number of geologists spent the week- 

 end in the district, examining the Silurians, with their igneous 

 intrusions, so well exposed in the numerous stream sections, and 

 paying particular attention to the basal beds of the Carboniferous 

 formation, besides noting the vividly displayed effects of the great 

 Dent Fault. Some fine specimens of Coal Measure plants were 

 obtained from the Barnsley district, in connection with the 

 Cawthorne excursion. 



The members of the section tender their congratulations to 

 its President, Dr. A. R. Dwerryhouse, on his appointment as 

 Lecturer in Geology in the University of Belfast. 

 The following were elected for 1910 : — 



President — H. Culpin, Doncaster. 



Secretaries — Cosmo Johns, Burngrove, Pitsmoor Road, Sheffield. 

 E. Hawkesworth, Sunnyside, Crossgates, Leeds. 



Representative on Executive— Godfrey Bingley. 



Representative on Committee of Suggestions—Professor Kendall. 



The Geological Photographs Committee of the Yorkshire 

 Naturalists' Union regrets that it is unable to report any large 

 increase in the number of photographs added during the year, 

 although those that have been sent well maintain the excellence 

 of the collection, and will prove to be valuable geological records. 



The Committee would like to draw the attention of the mem- 

 bers of the Union to an interesting field in geological photographs
