86 . Yorkshire Naturalists’ Union: Annual Report, 1912. 
GEOLOGICAL SECTION. 
Mr. John Holmes writes :—During Whit-week the coast 
sections between Thornwick Bay and Bridlington were exam- 
ined. At Askern fossils were collected from the marine bands in 
the Coal Measures; the material in which they were found 
having been brought to the surface during the sinking of a pit 
shaft. Sections were also examined in the Triassic (Bunter), 
and the Permian Limesitones. 
On the excursion to Low Gill an attemp! was made to trace 
the relationship between the red conglomerate of Westmorland 
and the green conglomerate which often occurs at the base of 
the Carboniferous rocks in North West Yorkshire It was 
believed that confirmatory evidence of the existence of an 
unconformity between the two conglomerates might be found 
in the many sections cut by the River Lune and its tributaries 
between Tebay and Ravenstonedale. 
The exposures on the left bank of the river were examined 
but the top of the red beds was nowhere seen. The excursion 
closed with a visit to the granite quarries at Shap. 
Coast EROSION COMMITTEE.—Mr. J. J. Burton, writes :— 
During the past year the waste of cliff between Robin Hood’s 
Bay and _ Saltburn-by-the-Sea, has been enormous. The 
exceptionally dry summer of IgIzr caused the land surface on 
the edge of the cliffs to shrink and crack, thus making it an easy 
prey during the winter and the recent very wet summer. 
All along the coast there has been much slipping, and it is 
quite safe to say the loss of land has been greater during the 
past year than for many previous years combined. The same 
remarks apply to Holderness, the loss of land at Hornsea and 
Withernsea being exceptionally severe. 
Jurassic FLORA CoMMITTEE.—Mr. J. J. Burton writes :-— 
The work done during the past year has been somewhat of a 
preliminary character in searching for and preparing new places 
inland for investigation. But much work of actual systematic 
investigation has also been carried out. The British Association 
gave a grant for the purpose, of which £5 was allotted to your 
Committee. The quarry at Marske has been further worked by 
Dr. Robt. Kidson, F.R.S., Mr. Hamshaw Thomas, Mr. Bow- 
man, Mr. Lane, myself and others. 
A new bed has been exposed on Roseberry Topping and has 
been found exceptionally rich in species. These are at present 
being worked out at Cambridge. 
Some work has also been done in the corresponding beds 
at Carlton-in-Cleveland. The terribly wet weather of the past 
summer has been much against all out-door work, and no com- 
bined: meetings of the members of the Committee have heen 
held in the field, but so much work of locating the beds has been
