TERMINAL MORAINES. 221 



cerning the great significance of the Missouri coteau has not 

 received from glacial writers all the recognition it fairly 

 deserves. But here we have, as in so many other instances, 

 fresh illustration of the fact that the minds of sagacious 

 investigators run in the same channel. Noteworthy in- 

 ventions and discoveries are not often due to the work of 

 single individuals. From the references already given, it 

 would appear that Dr. Dawson's surmise as to the signifi- 

 cance of the Missouri coteau, President Chamberlin's theory 

 as to the meaning of the Kettle Eange, Professor Cook's 

 delineation of the moraine across New Jersey, and Clar- 

 ence King's interpretation of the glacial accumulations on 

 the south shore of Massachusetts were, in the minds of 

 the authors, nearly contemporaneous and of independent 

 origin. 



The subject of this chapter will not be complete without 

 speaking of those later and more local moraines which were 

 formed when the ice had withdrawn itself from the country 

 in general, but still lingered everywhere in the mountains. 

 Such moraines are numerous in all the valleys of the White 

 Mountains. Professor Agassiz * describes no less than fifteen 

 terminal moraines of small size crossing the valley of the 

 Ammonoosuc, a short distance below Bethlehem. Similar 

 moraines exist in the valley leading down the Saco near 

 Bartlett, and in the White Mountain branches of the Andros- 

 coggin, as well as in the valleys leading to the vicinity of 

 Center Harbor, on Lake Winnepesaukee. The principal local 

 moraine of the Androscoggin is near the State line between 

 Shelburne, N. H., and Gilead, Me. This has been described 

 by Professor Stone and others. \ Other interesting moraines 

 described by Professor Stone in Maine are located at Read- 

 field Tillage, and at Swan Island in the Kennebec Valley, 

 and at Sabbattusville, Machias, and Waldoboro.
