Vol. 58. | GLACIER-LAKES IN THE CLEVELAND HILLS. 549 
Newlands a gorge called Stonedale was cut, much smaller than 
Oxdale Slack, but of the same general type: the cutting was 
commenced at about 360 feet and continued down to about 315 feet. 
This carried the drainage at all stages of the cutting of the Moor- 
Cottage and Craven-Hill overilows. In the earlier stages of the 
Stonedale overflow, an overflow was cut through the southern spur 
at Goosedale, but it was small and shallow. Ata later stage than 
that represented by Goosedale Slack, a retreat of the ice permitted 
escape by way of Cloughton, at first through Stonedale, Holm Hill, 
and Moor Lane, and later by Little-Moor Slack. A further retreat 
of the ice freed the eastern edge of Little Moor, and a sharp valley 
was cut parallel to the hillside, isolating a long hill known as 
Cober. ‘This hill is morainic at its northern end, while the 
southern end I found (from a temporary excavation at the residence 
of the late Sir Frank Lockwood) to be composed of solid rock. 
This ‘Cober’ valley has a free opening to the eastward at the upper 
(northern) end, while it also continues for a little distance to the 
north-west, where it makes a blind termination at some moraine-like 
hills. The valley previously referred to, as running from Holm Hill 
to Moor Lane, has a somewhat similar arrangement at its upper end, 
where it is closed by the sudden ascent of the valley-head. 
The next retreat of the ice produced results of a less equivocal 
nature—an easterly recession took place which freed a long straight 
hillside for a distance of about 1} miles. A new cut was com- 
menced at about 325 feet and was steadily cut down tv 255 feet, 
forming the splendid streamless ravine, Newlands Dale, through 
which the Scarborough & Whitby Railway now runs. The intake 
near Hayburn-Wyke Station and Hotel is at about the 250-foot 
contour. ‘The iceward boundary of the intake is very like that of 
the Cloughton-Cottage overflow, and perhaps, like it, is composed of 
Drift. 
I may now briefly reter to the strip of country between Stainton- 
dale and the sea. 
A line of morainic gravel-hills forms a strong ridge about 
Prospect House and Whin Hill, and the western face of this ridge is 
deeply guttered, as though by water flowing off the ice—a feature 
that is also well shown farther north at Danes Dale. 
At Heathard Point, at Rigg Hall, and to the east of Hast-Side 
Farm, are three Glacial stream-channels, but they have all been 
beheaded by the erosion of the coast ; and I am unable to say whether 
they drained lakelets, or merely, like those just named, flowed 
directly off the ice. Their magnitude renders the latter supposition 
improbable. 
There remains now 1n this section of country the great valley of 
the West and East Syme, extending from Harwood Dale to 
Burniston. This valley, which is bounded along the south side by 
the great Corallian escarpment of Hackness and Silpho Moors, is now 
occupied by two diminutive streams which flow westward and east- 
ward respectively from a low, scarcely perceptible watershed at
