Ii. Houlton—Meddybemps System. 
This system begins in Twp. No. 9, R. 4, Aroostook County, as a 
ridge running for two or three miles nearly parallel with the Black- 
water (or Alegwanus) River, which stream runs north-westerly into 
the Aroostook River. The ranges of hills which reach westward 
from Mars Hill, are here reduced to a few peaks and swells over- 
- looking a broad plain which forms the lowest depression in this chain 
to be found in that region. The ridge at this place is composed of 
gravel but little water worn, and the quartz and other hard fragments 
are quite angular. Interspersed in the gravel is a fine fertile soil to 
a considerable depth. This may show that sluggish currents clas- 
sified the gravel, or that the finer clay, etc., have been the result of 
the weathering of the soft fossiliferous fragments here abundantly 
found in the kame. From here, with a number of short gaps, the 
kame makes its way south-easterly over a rolling plain, to the north- 
west corner of Littleton, and thence southerly to Houlton. ‘There is 
no continuous valley along this route, and the kame several times 
passes from the valley of one stream to that of another, but it does 
not cross any hills more than 100 or 200 feet high, measured on the 
north side. At Houlton the gravel is much more water-worn than it 
is further north, and contains much material from the crystalline 
region near its source. It is here a prominent ridge, pell-mell in 
structure or obscurely stratified at the exposures examined, and it 
plainly meanders like ariver. It next runs south along a branch of 
the Medunxnekeag River, through Hodgdon, and then soon crosses 
obliquely to the east of the Houlton-Calais road, its course lying 
along a low valley, nearly parallel with that road for several miles. In 
‘this part of its course it is much broken, and often consists of a line 
of occasional gravel swells. Near the north line of Orient this kame 
joins II a, and for several miles south of the junction the kame is 
quite a large ridge, upon which the Calais road runs. In Orient it 
runs into the upper end of Grand Lake, and the evidence is con- 
clusive that it extends along and under this lake. The lumbermen 
in warping logs down the lake frequently strike it with their anchors.
