Postscript 



Between the time of handing the manuscript to the Secretary of the 

 Society and the receiving of the proof a field season lias intervened, 

 affording an opportunity to further investigate the different levels, and 

 as a consequence a number of changes should he noted. 



The altitudes of the glacial lakes have been rccheckcd; the important 

 changes are as follows : The South Meadows, from 2,000-2,040 to 1,950- 

 2,210 feet. The last figure is based on a splendidly developed beach that 

 establishes the glacial nature of this level. Newman Lake, from 1,740- 

 1,875 to 1,740-1,895 feet, especially in the Saranac quadrangle. The 

 Saranac glacial water levels, from 1,450-1,600 feet to 1,440-1,660 feet. 



The glacial character of the lower series of lakes in Keene Valley, from 

 the "Otis" down to the "Wainwright" levels, inclusive (altitudes, 900, 

 860-880, 840, 820-825, and 7 60 feet), is now being questioned. Some of 

 the "beaches'" are undoubtedly stream meander terraces and scarps, while 

 others are lake-shore features. Until distinctions in the important cases 

 can be made the nature of these levels must be left as an open question. 



The Elizabethtown Lake, first regarded as a morainal lake by Doctor 

 Hies and a glacial lake by the writer, appears to be marine in origin. Its 

 altitude is now given at about 600 feet instead of 660, and now it ties in 

 with the Clintdnville level at 647, which was recorded as 680 feet. 



Dr. D. YV. Johnson has rendered great service to the writer in problem 

 of local glaciation. We found in the cirque on the eastern slopes of 

 Esther Mountain a lateral moraine of unmistakable local origin, and, 

 together with other cirques and hanging valleys, the writer has become 

 convinced that the Adirondacks supported local glaciers.
