ON EKRATIC BLOCKS OF THE BRITISH ISLES. 2o7 



Reported hy Rev. George Style, M.A. 



Gigglesiuick. — On Grammar School Cricket Ground the pavilion is set 

 back into a glacial moraine containing numerous rounded to sub-angular 

 stones. They include millstone grits, Yoredale grits and shales, Hardraw 

 Scar limestone. Lower Carboniferous limestones, and Silurian grits. 



Note. — This deposit and the worn rocks and roches moutonnees from 

 the school buildings on to the Settle golf-links, by the Ebbing and 

 Flowing Well, suggest an ice-tlow coming over Buck Ha' Brow. The 

 moraine might, however, have been laid down by ice coming down 

 Bibblesdale by Horton and Stainforth. Further evidence required.
