ether kinds of trees. In the portion of the val- 

 ley traversed, Abies and Pseudotsuga were less 

 often met with than along the Gordon river 

 watershed. Acer macrophyUum and Alniis 



oregana appear more frequently along the banks 

 of this stream than along the other and occasion- 

 ally trees of Populus deltoides and Salix lasiandra 

 are seen. 



With distance, the windfalls characteristic of 

 the lower valley, disappear, and the shrubby 

 undergrowth assumes the same tone and is of 

 the same composition as that which we have 

 learned to know for the other valley. The 

 herbaceous undergrowth, because of the general 

 less dense nature of the forest, is more profuse. 

 In point of species, there is not much difference 

 and naturally many of these are common to both 

 places. The following species form the main 

 bulk of this herbaceous forest undergrowth: 

 Polystichiim munitum Asplenium filix joemina 

 Lomaria spicant Dryopteris spimilosa 



Deschampsia caespitosa Poa elata 



Agrostis aleutica Carex laeviculmis 



J uncus paucicapitatus Alsine crispa
