DAKYNS: SHAP GEANITE BOULDEES. 61 
the present water drainage, it would have been down the 
gorge of the Lune, below Tebay. But they did not go 
down the Lune. On Mr. Goodchild's map to illustrate the 
glacial phenomena of the Eden Valley (Quart. Journ. 
Geol. Soc, vol. xxxi.), the southern limit of the dispersal 
of Shap granite boulders on that side is drawn close to 
Tebay ; nor have I noticed them, in the depression extending 
from Kendal to the river Lune, further east than Docker 
Garth. On the other hand, I have traced these boulders 
north of Kendal, directly towards the granitic area. It seems, 
then, that these boulders came nearly due south from the 
parent rock across the high ground, formed of Upper 
Silurian rocks, over which the old coach road goes from Shap 
to Kendal. The highest point where the granite occurs in 
place — viz., Sleddale Pike, 1,659 feet above the sea — is 
higher than the greater part of this ground ; but the greater 
part of the granitiG area is lower than the ground across 
which the boulders travelled in their southerly course. 
Nor is there immediately to the north of the granite any 
ground as high as the granitic fell itself. It is clear, then, 
that the dispersal of the granite boulders did not take place 
by means of ordinary glaciers. The boulders must either 
have come over the Silurian fells on floating ice, or by means 
of an ice sheet moving southward regardless of the shape of 
the ground. At first sight it seems easier to suppose that 
they floated over ; but great difficulties stand in the way of 
such a supposition. The lowest part of the Silurian range, 
over which the boulders must have come, is the Hause. I 
do not know the exact height of this point ; but it is between 
1,300 and 1,500 feet above the sea, and is probably over 
1,400. Further, an examination of the distribution of the 
boulders south of Kendal shows that they still continued to 
travel in a lineal direction nearly due south ; they occupy a 
narrow band of country, whose long axis points directly for
