gypseous marls and new red sandstone, which have a large 
extent in the vale of York and the vale of the Trent. The 
red marls are not seen at the surface at any points near 
Selby, nor indeed, as borings have shown, do they extend 
so far westward beneath the newer deposits; but at Holme 
on Spalding Moor, they are shown in a large excavation. 
The Bunter sandstone lies immediately beneath the post 
tertiary deposits at Selby, and a few miles to the westward 
rises to the surface, forming two little wooded hills, called 
Brayton Barf and Hambleton Haugh. Westward of these, 
again, are the outcrops of the Permian and Carboniferous 
strata, and these strata no doubt extend beneath us here at 
Selby, although probably at an inaccessible depth. 
OX THE SOUTHWARD FLOW OF SHAP GRANITE BOULDERS. 
BY J. R. DAKYNS, ESQ., OF H. Iff. GEOLOGICAL SURVEY. 
Boulders of Shap Granite are plentiful near Kendal. 
How got they there ? Speaking generally, the dispersal of 
Lake country rocks took place radially ; the ice flowed out 
on all sides from the Lake mountains, following very much 
the direction of the present water drainage. The Shap 
granite area is situated at the extreme south-eastern end of 
the Lake mountains. The greater part of this area, sloping 
northward, drains into Wet Sleddale, whose waters forming 
the river Lowther, flow north, and joining the Eden, go out 
to sea by the Solway. The remaining portion, facing 
southwards, overlooks Wastdale Beck. This beck flows 
north -east along the strike of the rocks to Shap Wells ; 
here its waters turn sharp at more than a right angle, and 
thence flow south-south-east to join the Lune at Tebay. 
Had the Shap granite boulders, then, travelled south along
