is, I think,
nearly the same with that of the left bank of the river in which they
occur; immediately over the seam there is a small ravine, where three of
the veins are still farther exposed. Caricea, a new Dicranum, Alsophila
ferruginea, Polytrichum aloides, Bartramea subulosa, and Jungermanniae
are common near this spot.

Left Kamroop on the 19th, and proceeded in a S.W. direction for twelve
miles, when we halted on the Darap Kha, at the foot of the Naga hills,
opposite nearly to Beesala. Nothing of interest occurred.

_Feb_. _21st_.--Commenced the ascent, and after marching about ten miles,
halted in a valley near a stream. Temperature 66 degrees. Water boiled
at 210.5 degrees, giving an altitude of about 77 degrees, or 383 feet
above Suddiya. The road was very winding, the path good, except towards
the base of the hills: the soil sandy, in places indurated, and resting
on sandstone; but there is not yet sufficient elevation to ensure much
change in vegetation. Found Kaulfussia {61a} below in abundance,
observed Castanea and a Quercus; three species of Begonia, and three or
four species of Acanthacea. In other respects the jungle resembles that
of the Singpho territory. Dicksonia is abundant. Dipterocarpus of large
size occurs. Caught two innocuous snakes at the halting place. {61b}

_Feb_. _22nd_.--The distance of the march is about 12 miles, and we
halted after crossing the Darap Panee; some parts of the route were
difficult, at least for elephants. No particular features of vegetation
yet appears. The summit of the higher hills looks pretty. Tree jungle
considerable, open places with low grass, is the surrounding feature of
vegetation. The hill first surmounted from the halting place is covered
with a Camellia or _Bunfullup_, (i.e. bitter tea) of the Assamese. The
fruit has loculicidal dehiscence. In habit it is like that of the tea,
but the buds are covered with imbricate scales. At the summit of the
hill, it attained a height of 30 or 40 feet. Begoniacea, Urticaceae,
Acanthaceae, Filices, are the most common.

_Feb_. _23rd_.--Halted to enable the elephants to come up; they arrived
about 10 A.M. Temperature of the air 75 degrees, water boiled at 210
degrees, altitude 1029 feet. The Darap is a considerable stream, but is
fordable at the heads of the rapids. Fish abound, especially _Bookhar_,
a kind of Barbel, {61c} which reaches a good size. Clay slate appears to
be here the most common
