almost invariably along the edge. It is seldom 
met with in this region except as a border tree. 
The fir, Abzes amabilis, occurs frequently in the 
lower forest belt, and then stands in more or less 
exclusive groups or patches separated from each 
other by stretches of the more general forest. 
Taxus brevijolia is occasionally found as a small 
sized tree in the lower forest zone. Picea stt- 
chensis is the most abundant tree of the lower 
elevations and seems to attain its typical develop- 
ment in the immediate vicinity of the sea. Trees 
with a diameter of 1-2.5 meters and 40-55 meters 
in height are not uncommon. Thuja plicata 
also reaches large proportion but is more typical 
of the higher places where it occurs in greater 
numbers and larger size. 
Shrubby undergrowth.—Where the forest is 
very dense as for example along the river val- 
leys, there is not very much underbrush. On

shrubs and underbrush occur abundantly (PI.
