is succeeded as the forest is approached by a well 
established turf built up by a complex society 
of plants. Within this area the greatest variety 
of plant life of the region is to be met with, and 
it is here that the sharpest struggle is carried on. 
The two great factors, the forest and the sea, 
maintain by common consent as it were, this 
intervening skirmish place, each continually ex- 
erting powerful influences towards the other, 
which, as they commingle and permeate, give 
rise to a complexity of conditions made manifest 
in a highly complex plant population. Of con- 
ditions arising seaward and having a most direct 
bearing upon plant distribution over this area, 
are among others, ocean spray, wind currents, 
moisture, fogs and an equalizing influence of 
temperature. In like manner conditions arising 
landward, such as drainage, slope, texture and 
nature of the soil or rock, and the almost end- 
less complexity of conditions physical, chemical 
and biological which the proximity of the forest 
gives rise to, all aid in giving color to this ground. 
The conditions here experienced although some- 
what complex and many, still are uniform and
