the face of Mount Clinton, which has a westerly exposure, 

 it attains an elevation of 4250 feet ; while again, at the 

 " Ledge," the extreme northern termination of the north- 

 eastwardly ridge of Mount Washington, its limit is fixed 

 at about 3900 feet. The alpine region seems to occupy 

 the summits of only the three highest mountains; being 

 limited to from one to two hundred feet of the cones of 

 Mts. Adams and Jefferson, and some seven to eight hun- 

 dred feet of Mt. Washington. 



In the accompanying chart of the mountains, (Plate 

 XV.") I have attempted to show, by the irregular dotted 

 lines, the general lower limits of the subalpine region, and 

 by the regular dotted lines those of the alpine region. Tak- 

 ing our stand upon the summit of Mount Washington, the 

 main peak, and looking at the mountains which lie to the 

 north of it, it \\\\\ be seen, that, while the subalpine region 

 foUows along the main chain, it extends, also, a short dis- 

 tance along the spur which forms the ridge running south- 

 eastwardly from the peak of Mount Madison, and to a 

 much longer distance northeastwardly from Mount Wash- 

 ington, following the general direction of the carriage road, 

 and terminating at a lower limit than ordinarily at the 

 "Ledge," around which the road abruptly turns imme- 

 diately before it is lost in the forest. Southwardly from 

 Mount Washington there are three ranges of elevations; 

 a more prominent one, whose peaks bear the names of 

 distinguished statesmen of America, trending towards the 

 southwest; another which continues in the direction of the 

 main chain lying to the north of Mount Washington, 

 whose northernmost peak has received the name of Davis's 

 Spur; and a third, much less significant, dividing the angle 

 between the two former, but approximating much more 

 closely to the last mentioned. By the union of these three,
