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 i)owerful intluences 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 u{)on plant distribution over this area, 

 are among others, ocean sprav, wind currents, 

 moisture, fogs and an ec^ualizing 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
