Upon considering the foregoing tables we find that through 
the year the weather is better on the southern side than on the 
northern. But it may be mentioned that in February and 
March the weather is better on the northern side than on the 
southern. This fact will at least favour conifers which have 
cver-green leaves even in the cold winter and have power to 
do starch-building even then ; but will not benefit deciduous 
trees which have no leaves to enjoy the sunshine. 
4) Wind-direction. It is true that the wind plays a some- 
what important paft in making forest. The fact is the gentler 
the wind the better for the forest. So, the velocity of the wind is 
the important point for us. We have, however, no information 
about the wind velocity at the base stations of the mountain.
