and Tsenkan, which is on the same bank, and close to the entrance to the Kioukdweng, three villages are met with; but none of any size.  Tsenkan is prettily situated on a high bank, or rather low hill.  The houses are about 100 in number, all poor and small.  The stockade is a miserable affair.  There are some good Poonghie houses, and a very pretty group of pagodas on a small rock.  The country is jungly; just above the town a nullah enters the Irrawaddi:  it is down this that large quantities of teak is brought, from hills two days’ journey to the eastward; some large rafts were seen, but although some of the timbers were stout, none were of any great size.  I gathered a pretty Hippocrateaceous plant in the jungles, as well as a Combretum; a Vitex, an Amyridea, etc.  Phrynium dichotomum occurs here; Rosa continues; Jatropha is cultivated.

May 7th.—­Started at 5 A.M., and entered the Kioukdweng almost immediately.  We halted about 7, at Tsenbo.  Noticed AEsculus, Sisymbrium, Campanula, Adelia nereifolia, Dillania speciosa, the usual Compositae, and largish Dipterocarpeae.  The river is a good deal narrowed, but never less than 130 yards across, and as there are no rocks in any direction to impede the stream, the water flows but slowly and very placidly.  Almost all the rocks forming the hills are grey carbonate of lime.  These hills are covered to high-water mark, with scanty somewhat stunted trees, the most of which have no foliage.  The scenery is by no means so bold as in the upper K. dweng, although just above Tsenbo, there is a noble cliff, 300 feet high, and almost perpendicular; under its ledges we observed great numbers of bees’ nests.  The rock when exposed is rather greyish black, and in many places reddish.  Serpentine occurs, but is not common.  A good deal of lime is prepared in this Kioukdweng, and some portions of it in the rugged serrated appearance, remind one of the limestone cliffs on the coast.  Above Tsenbo and nearly opposite the cliff, is a small village of eight houses.  Tsenbo numbers fifteen; it is on the left bank, and is a miserable place.  Here we were left by our escort which accompanied us from Tsenkan, and the Thogee refused positively to give us two or three men to row.  Although master of a miserable hole, he had made preparations for defence, and had set on foot a custom house.  We saw a good many boats passing up, all evidently containing families moving away from their villages.

In this Kioukdweng a fine Palm exists, which I have never seen before.  Caudex 10-15 pedalis, crassa, petiolorum basibus processibus vestitis, frondibus pinnatis, 10 pedalibus, pinnis ensifornibus 2 to 2.5 pedalibus, subtus glaucis, diametro 1.5 uncialibus, basi valde obliquis, bilobis! lobo inferiore maximo, decurrenti, uninervi:  floribus in spadicibus nutanti-curvatis, amplis, basi spathaceis spicato-paniculatis.  Florib. masculis polyandris.

Petiol. bases cretosae, intus processubus atris, subulatis, longissimis robustis quasi panicillatis.
