KENDALL : THE GLACIATION OF YORKSHIRE. 
had its radiant point in Finland, and this mere probability becomes 
a well-grounded induction when we observe the way in which the 
stria) down the whole eastern coast-line of the British Isles are 
deflected, and in some cases our native streams were actually turned 
in upon the land as in the classic case of Caithness. Even on the 
remote Shetlands we find a similar effect, and those islands have been 
shown by Messrs. Peach and Horne to have been buried beneath a 
moving sheet of land-ice which bore down upon them from the east. 
On the Yorkshire Coast the evidence of stria) is remarkably scanty, 
one single striated surface having been found by Mr. Lamplugh* at 
Filey Brig coming in from the N. 20° E., but curvature of the bed-rock 
due to glacial pressure, has been noted by the same acute observer at 
Flamborough Head, and the occurrence of huge transported masses 
of friable secondary rocks at various places to the southward of their 
native outcrops, and of a great moraine along the coast for 
many miles would suffice, I think, to convince most investigators 
that an ice-sheet had pressed in against the coast with a strong 
northerly component of motion. 
Mr. Lamplugh has suggested that probably theTeesdale(Stainmoor) 
glacier had not, up to the time of the onset of the Scandinavian ice, 
reached the sea, but that as the glacial period approached its 
culmination the great accumulation of snow and ice in the British 
Isles caused a relative desiccation of the region lying to the east- 
ward, which would, of course, obtain their precipitation from the 
westerly winds which had already traversed the British area. He 
supposed that as the British glaciers waxed there would be a 
dwindling of the Scandinavian ice-sheet, and our native ice-stream of 
Stainmoor would at last succeed in reaching the sea, would there 
be deflected when it abutted against the front of the Scandinavian 
ice, and would be driven to the southward, rasping the faces of the 
cliffs, tearing off great masses of our soft secondary beds, and bearing 
them along to be stranded further south, sometimes at higher levels 
than the parent masses, scattering its burden of Snap boulders, and 
leaving a great line of morainic hills along the sea-board. 
This explanation is, I think, a feasible one, but I am still 
disposed to think that the order of events was not quite the same
