WATER-SPOUTS ON THE YORKSHIRE WOLDS. 227 
at the time attributed the excavation of the dales to a dif- 
ferent origin, viz., to water flowing out at the head of a dale 
as the land rose above the sea. I never could accept this 
theory, and I hardly imagine they accept it now. 
To revert to the first question. If, as I suppose, the 
Wolds had a small ice-cap of their own in the glacial period, 
A CHASM ON THE HILL SIDE. 
might not the confluence of the dales, already formed in part, 
but occupied by miniature glaciers, have resulted in the 
small hollow in which the village of Langtoft is built, 
sufficient, notwithstanding the subsequent drainage from 
the rainfall, to prevent the direct outfall till the water had 
obtained a certain level ?
