Having provided doolies, or little bamboo chairs slung on four men's
shoulders, in which I put my papers and boxes, we next morning
commenced the ascent; at first through woods of the common trees,
with large clumps of bamboo, over slaty rocks of gneiss, much
inclined and sloping away from the mountain. The view from a ridge
500 feet high was superb, of the village, and its white domes half
buried in the forest below, the latter of which continued in sight
for many miles to the northward. Descending to a valley some ferns
were met with, and a more luxuriant vegetation, especially of
_Urticeae._ Wild bananas formed a beautiful, and to me novel
feature in the woods.

The conical hills of the white ants were very abundant. The structure
appears to me not an independent one, but the debris of clumps of
bamboos, or of the trunks of large trees, which these insects have
destroyed. As they work up a tree from the ground, they coat the bark
with particles of sand glued together, carrying up this artificial
sheath or covered way as they ascend. A clump of bamboos is thus
speedily killed; when the dead stems fall away, leaving the mass of
stumps coated with sand, which the action of the weather soon
fashions into a cone of earthy matter.

Ascending again, the path strikes up the hill, through a thick forest
of Sal (_Vateria robusta_) and other trees, spanned with cables
of scandent _Bauhinia_ stems. At about 3000 feet above the sea,
the vegetation becomes more luxuriant, and by a little stream I
collected five species of ferns and some mosses,--all in a dry state,
however. Still higher, _Clematis, Thalictrum,_ and an increased
number of grasses are seen; with bushes of _Verbenaceae_ and
_Compositae._ The white ant apparently does not enter this
