Jan 19th.—­We reached Negrigam early in the forenoon although we did not leave our ground before 10 A.M.  The road to the village was pretty good.  Negrigam is a largish village on the north bank of the Booree Dihing, which is here a considerable though not deep stream.  This bank is at the site of the village very high.  The population seemed to be considerable.  To the south, large ranges of hills were visible, the first of which were close enough to admit of one’s distinguishing them to be wooded to the top.  The inner ranges were lofty.  We had some difficulty in ascertaining where the tea was located, the accounts being rather contradictory.  At length we proceeded up the bed of a small river, Maumoo, which runs into the Booree Dihing close to the village:  after wading along in the waters for two hours we arrived at a khet where we encamped.  The direction being from Negrigam N.W. along the banks of this stream.  The Pavia I first observed at Silam Mookh, was abundant, and some of the specimens were very fine, the largest was a handsome, very shady tree, of perhaps thirty feet high.  The only plant of interest was Gnetum scandens.  On a high land bank I gathered a species of Polytrichum, and one of Bartramia.

January 20th.—­This morning we crossed the small streamlet Maumoo, ascended its rather high bank, and within a few yards from it came upon the tea:  which as we advanced farther into the jungle increased in abundance; in fact within a very few yards, several plants might be observed.  The plant was both in flower and ripe fruit, in one instance the seeds had germinated while attached to the parent shrub.  No large trees were found, the generality being six or seven feet high; all above this height being straggling, slender, unhandsome shrubs:  the leaves upon the whole were, I think, smaller than those of the Kujoo plants.  With respect to the plants with which it is here associated, I may observe that they were nearly the same with those of the Kujoo jungle, but here there was nevertheless one striking difference, that the jungle was by no means so dark in consequence of the smaller size of the jungle trees.  The underwood consisted chiefly of ferns, among which Polipodium unitum was very common, and a Lycopodium.  Bamboos occurred here and there, although by no means so extensively as at Kujoo.

Chrysobaphus Roxburghii, and a new Dicksonia, D. Griffithiana, Wall. were the plants of the greatest interest.  With regard to the limits of the tea, it is by all accounts of no very great extent; but this is a point upon which it is difficult to say any thing decisive, in consequence of the thickness of the jungle.  The space on which we found it may be said to be an elbow of the land, nearly surrounded by the Manmoo river, on the opposite side of which, where we were encamped, it is reported not to grow.  Within this space the greater part consists of a gentle elevation or rather
