It appears in several places along the shore, running as gently sloping 
points far out into the lake, and it emerges as ‘“ horseback ’’ islands. 
At the south end of the so-called ‘‘ Arm of Grand Lake,” it forms 
a moderate sized ridge of coarse sand or very fine gravel, plainly 
stratified, the strata dipping 35° lengthwise of the kame, which is 
here running south-easterly into a remarkable pass through the high 
ranges which form the continuation of the Mt. Desert Highlands. 
One fourth of a mile south of the arm of the lake, in the jaws of 
this pass, the kame disappears from the surface, and is buried out of 
sight by a mass of boulders and other coarse glacial debris. I could 
not discover evidences of an ordinary land-slide, nor of a channel 
cut in the lower till. More probably these boulders tumbled into the 
channel of the kame-stream from the ice at the sides. The shrewd 
builders of a road through this wilderness found this underlying 
gravel, and their excavations revealed the above stated facts. The 
stratification of the kame at this point shows that a kame river cer- 
tainly flowed south-eastward through this Spruce Mountain pass, and 
over a low divide, not more than thirty or fifty feet higher than — 
Grand Lake. To the south of this divide no gravel can be found for 
‘several miles along a-slope of about twenty feet per mile. 
It would be interesting to know how far south of the lake the 
kame continues covered out of sight by the upper till. The fineness 
of the gravel in the pass shows that the current might be expected to 
sweep all sediment from its channel when once it began to flow down 
the steeper slopes to the south, providing the slope of the land had 
any effect on the flow of water. From Grand Lake there are two 
lines of valleys favorable for the flow of a kame-stream, one south- 
eastward via Scott’s Brook to the St. Croix River, and the other 
down the valley of Tomah Stream. The stream seems to have 
taken the latter course. After a gap of about five miles the kame 
begins again not far south of Tomah Station on the European and 
North American railway, and soon expands into extensive sand and 
gravel plains, that is, systems of reticulated ridges.. These extend to 
near the mouth of Little Tomah Stream, where a single ridge begins’ 
and continues south along the west side of Tomah Stream. It crosses 
the Schoodie River into Baileyville, and thence goes by a low pass in 
Alexander (where it is much broken), to Meddybemps Lake, where 
it expands into quite a large sand and gravel plain. ‘This must have 
been the terminus of the kame stream, during some part of the 
kame period, but a line of occasional gravels shows that at one time
