Map of the Great Range, White Mountains, N. H. 



This map has been prepared to show the extent of the alpine districts of the White mountains, to 

 illustrate Excursus I. It is based-upou that prepared and published by Mr. W. H. Picliering in liis little 

 Walking Guide to the Mt. Washington Range. His lines have been followed for the contours, streams, 

 paths and forest limits. Some slight additions have been made, and by the use of colors the extent of 

 the forest region and the division of the alpine region into two districts have been clearly shown. The 

 difference in the height of the forest line in different parts of tlie range, as modified by the exposure or the 

 proximity of deep ravines (first made apparent by the measurements of the late Professor Guyot) are 

 here well brought out, but probably require some modification. The heights of the contour lines are in 

 English feet. The heights of tlie several mountain summits are taken from Guyot's measurements of 

 nearly thirty years ago. Doubtless more correct determinations are found in Prof. E. C. Picliering's figures, 

 viz.— Washington, 6293'; Clay, .loSl'; Jefferson, 5736'; Adams, 5819'; Madison, 5381'; Monroe. 5396 ; 

 Franklin, 4923'; Pleasant, 4781' (See Appalachia, iv. :321.) 



The path leading to the summit of Mt. Madison from the west branch of the Peabody River should 

 have been marked Osgood Path and not Watson Path.
