that the forest-formation attains its most luxuriant growth at 
the 2000 m. elevation. Next, I have dwelt upon each region 
more particularly and stated the maximum and minimum 
limitations of the growth. Then, the zonation of plant-regions 
has been discussed zone by zone. The species of each region 
are mentioned and the lists of plants given. I have also 
summarized all the plants in one table, and given a short note 
on the general aspect of the flora of the mountain. The plants 
contained in the table are in all 739 species belonging to 96 
families. Next, I have considered the effect of fires, and come 
to the conclusion that the present prairie is mainly due to forest- 
fires. Lastly, I have considered the cause of the absence of 
Pinus pumila and stated that the wind direction is not suitable 
for conveying the seeds of the Finns from the neighbouring 
mountains to the volcano.
