THE AMERICAN BOTANIST. 75 



precipitous in many places and at once falls away to the broad 

 valley of the Battenkill. 



Leaving our horse at a farm house near the foot of the 

 mountain, we decided to climb to the main peak by the most 

 northern of the hollows as they were set down on the map, 

 which one of our party had thoughtfully provided. Tliis 

 hollow proved to be a glen in which there must have been at 

 times quite a respectable stream, when the melting snows of the 

 upper mountain were the source of its supply. At this season 

 of the year, however, it was shrunk to a small brook which 

 was sometimes all but lost under the roots of trees or project- 

 ing ledges of rock. 



At the entrance of this glen or hollow we found some in- 

 teresting mosses among which were Blinda acuta and Euca- 

 lypta streptocarpa. Among these mosses we also found the 

 algae, Trentophylla aurea. The farther up the glen we went 

 the steeper became the climb, until we were forced to pull 

 ourselves up by shrubs and the branches of overhanging trees. 

 We still kept to the bed of the rivulet which here came tumb- 

 ling down in a succession of small waterfalls. The rocks 

 in the bed of the little stream were covered with that water-

 variety purpurea of Gray's Manual as it showed the purplish 

 leaves to a marked degree. Here was also the rare mountain 

 moss Gymnostonium rupestre. Among other mosses noted on 

 our way up the mountain were, Dicranuin flagellare, Hypnum 

 engyrium and Myurella Careyana. Of scale mosses we found 

 Frullania Asagrayana and Rehoulia (Asterella) hemisphaerica 

 as well as two of the Cephalozias, namely C. hiciispidata and 

 C. multiflora. 



At the head of the glen we came out upon a shoulder of 

 the mountain and here we were impressed by the sudden 

 change in the flora. The transition to the sub-alpine forms 

 was very marked. A little way below, the trees were in full
