 I . Salal formation. 



Between the formations of the beacli already 

 considered and those of the forest proper, lies 

 a well differentiated zone of vegetation which 

 derives its distinctive marks from the strong 

 development in it of the salal or Gaiiltheria 

 shallon. Other shrubs and herl)s go to make 

 up its composition, yet the salal is the dominant 

 species and attains here in this transition area 

 between forest and beach its characteristic devel- 

 opment. The zone exhibits such uniformity and 

 continuity throughout that it is best c<.)nsidered 

 as a distinct formation. 



x\long the outer edge of the salal, generally 

 in under the overhanging branches, are found a 

 few shade-loving plants which occur more typic- 

 ally, it seems, in the forest. Most frequent of 

 these are:- 

 Carex deu'eyana Unijoliiim hijoliiim dilatatum
