Setting it aside, therefore, let us proceed to examine the direc- 
tion of the wind. 
As the wind is a means of conveying plant seeds to a dis- 
tance, the discussion of the wind-direction will throw some light 
upon the questions whence and how plants were first brought 
to this volcano. 
The following table shows the wind-direction at the different 
stations.

Tab. XVI. Showing the wind-'directioDs at the different stations. 
As the mountain lies in the so-called monsoon region, the 
north wind prevails in the winter and the south wind in the 
summer. But the wind at the region under consideration is 
somewhat changed owing to the high mountain. Thus the pre- 
vailing wind throughout the year is the south wind. 
As we have previously stated, the mountain must have been 
entirely barti, until it entered the extinct stage. After having 
become ready to give plants their stands, it must have received 
first some inhabitants from the neighbouring mountains. I have 
come on this occasion to consider that the wind is the only means 
of conveying plant-seeds to this mountain. The wind must,
