GENERAL DESCRIPTION OF THE KAME SYSTEMS OF MAINE. 
For convenience these systems are numbered, beginning on the 
east. Several of them branch like rivers, and all kames supposed to 
be connected are here classified as a single system, the longest trib- 
utary being regarded as the main kame and the others as branches, 
and all are numbered accordingly. ‘The first letters of the alphabet, 
a, b, ete., are annexed to the system number to designate branches 
plainly connected with the main kame; m, n, etc., to designate 
probable branches; 2, y, etc., to designate kames whose connections 
are decidedly in doubt, but cannot yet be proved to be distinct from 
the system to which they are thus provisionally annexed. The use 
of the middle and last letters to indicate degrees of doubt as to the 
connections of kames has been found necessary, partly because they 
are not fully explored, and partly because of the gaps which are 
almost always found in the kames on steep down slopes, or in val- 
leys where the streams have often washed them away in great part, 
or in regions which were under the sea in the Champlain period, 
where since deposition, the kames have often been wholly or in part 
re-classified, or covered out of sight by marine deposits. 
These systems have been mapped in greater part from my own 
observations, which have been made at intervals during the last four 
years. An instrumental survey of so great a field was cut of the 
question, and hence my method has been by a reconnoissance to 
locate the kames by reference to such features as will be sure to be 
shown on an accurate map of the State, when one is made. It is 
believed that on the scale of a small map, this will show the topo- 
graphical relations of the kames with sufficient accuracy. Where 
kames have been mapped from the reports of others, it has only 
been after careful tests of their accuracy, and after being confirmed 
by the testimony of several. 
I. St. Croix River System. 
Not yet fully explored. Itis said to originate in New Brunswick in 
the valley of Palfrey Brook. It crosses Chiputneticook Lake, and 
follows the valley of the St. Croix River to the mouth of King Brook, 
and perhaps to Chiputneticook Falls, and probably connects with the 
kame which reaches along the lower Moannes valley to Baring, 
Charlotte and Pembroke. Near the mouth of Canoose River, this 
kame sends off two series of kame-plains south-easterly, one on 
each side of Basswood Ridge, each about five miles long. Possibly
