MODIFIED DRIFT OF THE LAKE DISTRICT. 12/ 



feet high. Another tributary to the lake a niile farther south-east is bor- 

 dered by terraces of similar height near its mouth. On the north-east 

 side of Twenty-mile bay, two miles south from Melvin village, a bold 

 shore of coarse till, with many large boulders, is bordered by an old 

 beach, about 300 feet long and 100 wide, which slopes from the water's 

 edge to ten or twelve feet above high water. It is composed of_ fine 

 stratified sand, which is clayey below a foot or two of the surface. No 

 tributary occurs here, but a small stream at an eighth of a mile south- 

 east has brought down considerable alluvial sand, none of which, how- 

 ever, lies more than five feet above high water. 



Kavies. Half a mile farther south we find a kame extending two 

 thirds of a mile from north-west to south-east along the top of a hill 

 about 100 feet above the lake. It does not form a definite ridge, and could 

 hardly be distinguished from the till by its contour. Its materials are 

 coarse and fine gravel and sand interstratified. Boulders are enclosed in 

 many portions, but a well at Charles G. Edgerly's, 30 feet deep, encoun- 

 tered no boulders, being all the way through sand or fine gravel. Nine- 

 teen-mile bay and brook are a half mile farther south. Here the road 

 passes over the alluvium brought down by this brook, which, like that at 

 the head of Twenty-mile bay, is only three or four feet above the lake. 

 Nineteen-mile brook is bordered by considerable widths of low alluvium 

 for two miles above its mouth, to where it is crossed by the road a mile 

 and a half south from Mackerel Corner. From the brook to this village, 

 and for a half mile farther north, kame-like deposits of limited amount are 

 seen here and there at heights of 100 to 200 feet above the lake. East 

 from this road interesting kames extend more than a mile along the 

 north-east side of Nineteen-mile brook. These cover a width of a fourth 

 of a mile, consisting of successive small plains from half an acre to two 

 or three acres in extent, usually surrounded by hollows, and rising one 

 after another from 30 or 50 to 100 feet above the stream, or fully 150 feet 

 above the lake. These small level-topped deposits consist of sand and 

 water-worn gravel, with the largest pebbles about one foot in diameter. 

 Boulders are occasionally but not frequently enclosed. These kames 

 begin about two miles south-east from that described between Twenty- 

 mile and Nineteen-mile bays. These and the similar deposits which oc- 

 casionally appear about Mackerel Corner probably had a common date
