the train a visit was i^aid to tlie tile works, where the laminated 
muds formed on the floor of the ancient lake were examined. 
The northern slope of Eskdale was then mounted, and Ewe Crag 
Beck ascended. This, Mr. Kendall explained, was the overflow 
channel into Eskdale Lake of some lake lying to the north, 
and held up by the ice-front against the northern slope of the 
moorlands. The deltas of this glacial stream are clearly to 
be seen in two marked terraces above Dale End. These corre- 
spond in height to the two channels of Moss Swang on the 
southern side of Eskdale, seen the previous day, and mark the 
height of the lake at two periods in the retreat of the ice. 
As the actual level of the rock channel is of consequence to 
the theories of origin, no fewer than fifty-four bore holes have 
been made by Mr. Kendall in the peat to test its depth, with the 
result that the rock channel is found exactly at the height which 
corresponds with other related channels. 
From the northern end of Ewe Crag Slack the party crossed 
Danby Low Moor, knee-deej) in heather, to Little Dinnond, 
whence a return to civilisation was made by way of the Nan Stone 
to Hardale Head, and Hardale, Slack, another overflow glacial 
valley, was descended to Lealholm station, where the train 
was taken to Whitby. 
After dinner the General Meeting was resumed under the 
presidency of Mr. W. Whitaker, F.R.S. Mr. P. F. Kendall, 
F.G.S., continued his description of the glacier lake systems of 
Cleveland, directing his attention to the area between Whitby 
and Scarborough. The ice, he said, invaded Iburndale almost 
to its very head, and there is a low channel, almost at the head, 
through which the drainage of the Iburndale Lake was discharged 
into Robin Hood's Bay. When the ice filled Robin Hood's 
Bay, it turned these drainage waters southwards, and a great 
intercepting drain was formed (Jugger Howe Beck). There 
w^ere many oscillations of the ice-front, and oxbows were formed 
at several points, both on the iceward and opposite sides of the 
valle}'. On the withdrawal of the ice, which appears to have 
been very rapid, no evidence was left of any drainage at a le s
