pear in the valley at various intervals. At a point about two miles 
above Winchester village appears what is strikingly like a portion of 
a terminal moraine. 
No. XIX we may for the present begin below Nashua, N. H., 
passing through Tyngsboro’, Mass., Chelmsford, Billerica, Bedford, 
Lexington, Waltham, Newton, Dedham, Norwood, Canton, and 
thence southward to the Taunton river. This information is fur- 
nished, in Chelmsford by Mr. Butterfield, and in Newton by Rev. 
Mr. Slocum, who has mapped them for me, and for the rest of the 
course by Rev. A. E. Winship. He speaks, however, of a series 
more to the east, which perhaps is the continuation of this, passing 
through Holbrook, west part of Abington, east part of Brockton 
and Bridgewater, and through Middleboro. 
No. XX. This I begin for the present in Groton (east part) 
through Boxboro, Littleton, Framingham (?), Foxboro, Mansfield. 
Who knows the towns intervening? 
(Kames are crossed by the Fitchburg R. R. in Littleton near 
Sandy pond, Ayer Junction near Mossy pond, Shirley, East Fitch- 
burg, near Ashburnham depot. In Winchendon, for some distance, 
the Cheshire R. R., follows a kame towards Fitzwilliam, N. H.) 
No. XXI. Mendon, Blackstone, and on towards Providence, R. I. 
No. XXII. Passing into the Connecticut valley, I am anxious to 
know more about the kames appearing in Peterboro, N. H., and run- 
ning south through Rindge, Ashburnham, West Fitchburg, and 
Winchendon. 
(Two miles north-west of Keene, N. H., the railroad passes 
through a fine development of kames.) 
No. XXIII. We mention also, as the last of which we have in- 
formation, the Connecticut river kame proper, extending, with vari- 
ous interruptions, from Colebrook, N. H., to the Massachusetts line. 
(The Rutland R. R. crosses a well-developed kame, one mile north 
-1 Trustworthy facts are accumulating slowly respecting this series. From Hud- ° 
son, east of the Merrimack, a well-defined kame extends to the river near the iron 
bridge in Tyngsboro. On its way it passes through Tyng’s pond, causing a line of 
shodls through the centre, between the abutments of the ridge which descends to 
the water from high grounds to the north, and rises out of it by the log-cabin on 
the south. The river road (on the north side) to Lowell crosses two other kames 
nearer the city; one of which (near the Pawtucket bridge) is now being rapidly 
removed for its gravel. This, most likely, connects itself with gravel ridges com- 
ing down through Pelham in the valley of Golden brook. On the south side of the 
river, near the Poor farm in Lowell, and two miles west in Chelmsford, and far- 
ther south and west in Westford, kames are well marked.
