No. XII appears in Fryeburgh near the New Hampshire line, and 
follows the Saco valley as far as Buxton, a few miles above Bidde- 
ford. This series is spoken of as consisting largely of plains. 
No. XIII is traced from Conway, in N. H., to Ossipee lake, thence 
along Pine river, and past Pine River pond and Balch pond into 
Acton, Me., thence south-easterly through Sanford, North Berwick, 
and into Wells. 
No. XIV appears, perhaps, in Thornton, in the Pemmigewasset 
valley, and again at Meredith and Wiers and in Guilford, along the 
south-west shore of Lake Winnepiseogee, through Alton and into 
New Durham, and on through Farmington and Rochester to Dover 
and Portsmouth. . 
No. XV is shorter, running from Epping through Fremont, Kings- 
ton, South Newton, South Hampton, Amesbury, Mass., to Newbury- 
port. 
I regard No. XVI as beginning in Candia, passing through Ches- 
ter, Sandown, East Hamstead, Plaistow, N. H., and Maverhill, 
Groveland, Georgetown, Boxford, Topsfield, Wenham, and Beverly, 
Mass. ‘This is the Haverhill series described in my previous paper. 
No. XVII perhaps begins in Franklin, N. H., and appears below 
again in Sanbornton, Boscawen, and Concord, thence down the 
Merrimack river to Manchester, thence through the north part of 
Londonderry, and Derry, with some interruption, to Salem, N. H., 
thence through Methuen, Mass., Lawrence, Andover, Wilmington, 
Reading, Wakefield, Melrose, to Malden. ‘This is the Andover 
series, as described in my previous paper. 
No. XVIII is shorter and somewhat more indistinct. But it is 
tolerably clear, beginning at West Windham Station, in N. H., 
thence south-east through Pelham, Dracut, in Mass., crossing the 
Merrimack three miles below Lowell, thence through Tewksbury, and 
probably through Burlington and Winchester; the line would natu- 
rally strike the remarkable kames in Kingston and those running 
through Plymouth to Sandwich. 
Between this and the preceding series another intervenes for a few 
miles. South-east of Haggit’s pond in Andover is an extensive 
sand plain. Coming out of this in Tewksbury, just east of the 
State almshouse, is a well-defined kame, which continues four or five 
miles south-east into Wilmington, crossing the Shawshin river at 
an acute angle above Burt’s mills. This disappears in sandy plains 
to the south. In Woburn and Winchester kame-like deposits ap-
