This is the most abundant vegetation on the mountain. As 
shown in the annexed map, the region forms a nearly complete 
belt around the middle of the mountain, the only intrusion of 
volcanic ashes being on the eastern side where this formation 
lias almost disappeared. On the south, the formation begins at 
1550 m. and stretches up to an elevation of 2300 m. On the 
north, it comes a little lower than on the south. Distant views

On the south side of Part I., (cf. the foregoing sketch) on 
the lower boundary of this formation, there are found a few
