verse sections‘and the lines of borings shown in fig. I. 
Puate XXIV, 
Relief-map of the Northern Cleveland Watershed between Danby Beacon 
and Kempston’ Rigg, on the scale of about 2 inches to the mile. The south-

Prats XXVIII, 
Contoured map of the country between Hellwath and Cloughton, on the 
scale of about 2 inches to the mile. The shaded band cn the west, from Hell- 
wath Slack to West Syme, indicates the approximate margin of the ice at, or 
near, its maximum extension. 
Pratt XXVIII. 
General map of the glaciers and glacier-lakes of the Cleveland area, at the 
period of maximum extension of the ice, on the scale of 2 miles to the inch. 
The area covered by ice is left unshaded; the lakes are indicated by mar- 
ginal shading; and the area occupied neither by ice nor by lakes is crossed- 
hatched, to show the relief of the land. The edge of the ice is indicated by a 
heavy black line. Broken lines are used upon the south and west, as the 
marginal phenomena have not yet been studied. Contours, as throughout, 
in feet.
