the State, these long ranges of hills would make further flow of the 
glacier impossible, unless to the east or west. Long before that the 
higher ranges must have arrested or deflected the flow, and the extra- 
ordinary deflections of the striae in the region north and west of 
Mt. Ktaadn, may be due to this cause. And it is due to the fact that 
the streams flow eastward or westward for so large a part of their 
courses, on account of these transverse ranges of hills, that the 
kames so commonly do not follow the valleys of the rivers, and thus 
have escaped erosion. . Only a few fragments of the magnificent 
kame system of Maine, would have remained for our examination, 
had the kames been subjected to the violence of the rivers in the 
valley drift period; and no doubt many kames were washed away 
and re-classified as valley drift, during the rush of waters which 
characterized that period, as may be seen in the valley of the Ken- 
nebec. | 
2. The St. John Slope. 
This slope is drained by the St. John River, and numerous tribu- 
taries, the largest of which are the Allegash, flowing north, and the 
Aroostook, flowing east. The grand divide which separates this from 
the southern slope, is in general quite flat, and in many instances 
lakes and swamps near the divide have outlets both ways. Over 
this slope the average fall per mile toward the north and east is from 
two to three feet. Most of the region may be described as a great 
monotonous plain, abounding in swamps and varied only by a few 
peaks and some low rolling highlands. The area of the slope is com- 
puted at 7400 square miles, its length 117 miles, its breadth about 90 
miles. During the melting of the glacier the action of the waters 
must have been very different on this gentle slope towards the north 
and east, from what it was on the steep southern slope. 
DISTRIBUTION OF THE KAMEs. 
In the western part of Maine the most northern kames are those 
found a few miles north of Kennebago Lake, reported by Mr. Hunt- 
ington of the N. H. Geol. Survey. On the east the most northern 
kame is found in Township No. 9, Range 4, west of the East line of 
the State. A straight line connecting these points passes within a 
few miles of the northern extremities of such of the intermediate 
kames as reach farthest towards the north, and is roughly parallel 
with the coast. North and west of this line there are occasional hil-
