 made from Nasawana, a village at its base, elevated rather over 

 200 feet above the sea, and distant about a mile and a half north- 

 east from the peak. On the way to the foot of the mountain we 

 traverse an undulating region of basaltic andesite,^ which is merely 

 the extension to the base of the mountains of the basaltic Lambasa 

 plains. After commencing the ascent of the steep slopes, we find 

 exposed in a stream-course, 700 to 800 feet above the sea, a
