Upper Part of the Stony Brook Trail 



Above the old clearing on the Stony brook trail the 

 character of the vegetation undergoes a marked change 

 as compared with that on the lower slopes. In addition 

 to the difference in the nature of the underlying rock, 

 which in this region influences greatly the character of 

 the soil, fire following the lumbering operations seems to 

 have wrought a more complete destruction of the primeval 

 vegetation, and the gradual evolution of the vegetation on 

 these upper slopes back to a climax forest typical for 

 the region and soil will be interesting to observe and 

 make the subject of future records. The attainment of 

 such a growth will undoubtedly take a long time, but 

 records of its developmental changes should be kept by 

 frequent surveys. The characteristic vegetation of the 

 lower slopes below the clearing is here gradually, in some 

 places rather abruptly, surplanted by a vegetation prefer- 

 ring more sterile or acid soil conditions, due in large 

 measure to the fact that the underlying formation is 

 Olean conglomerate. Increased exposure of the forest 

 floor to intense sunlight following lumbering, and the 

 leaching effect of heavy rainfall have also contributed to 

 the increased sterility of the litter on the ground. The 

 characteristic species of the ridge and adjacent slopes are :
