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 rock, and forms in many places the very precipitous banks of the river.  Alsophila ferruginea, Areca, Calami, Fici., Pentaptera, Laurineae, Myristiceae continue.  Kaulfussia assamica, is common along the lower base of the hills.

Feb. 23rd.—­Started at 7, and after a march of five hours, reached the halting place on the Kamtee-chick, some distance above the place at which we descended to its bed.  Distance 12 miles, direction S.S.E.; crossed one hill of considerable elevation, certainly 1000 feet above the halting place, which we find by the temperature of boiling water to be 1413 feet above the sea.  The tops of these hills continue comparatively open, and have a very pretty appearance.  The trees, however, have not assumed a northern character; their trunks are covered with epiphytes.  The Kamtee-chick is a small stream fordable at the rapids, the extreme banks are not more than 30 or 40 yards.  No peculiarity of vegetation as yet occurs; the fruit of a Quercus continues common, as well as that of Castanea ferox.  I met with that of a Magnolia; Tree ferns, Calami, Musa, Areca, and the usual sub-tropical trees continue; Acanthaceae are most common, Gordonea plentiful on the open places on the hills, Sauraufa two species, Byttneria, etc. etc.  Altogether, I am disappointed in the vegetation, which, although rich, is not varied.  Wallichia continues common.  A Begonia with pointed leaves, and a Smilacineous plant are the most interesting, and a large Quercoid Polypodium, the lacineae of which are deciduous; and these I found in abundance on the Mishmee hills, although I did not succeed in getting an entire frond.
