26th.—­We left Mymensing this morning, and proceeded down the Burrampooter, the banks of which still present for the most part nothing but a succession of sandy banks covered with Saccharum spontaneum.  The stream is not very rapid, and the river, owing to the numerous islands and banks, does not present so imposing an appearance as the Ganges.  For the last week strong easterly winds have prevailed.

27th.—­We entered the mouth of the Soormah, or, as the natives seem to call it, the Barak.  The water of this river or portion of the Megna? is remarkably clear, compared with that of the Ganges; as indeed is that of the Burrampooter.

30th.—­Some time after we entered the Soormah we apparently left its channel, and up to this morning we have passed through a tract of jheels with a few clear and very deep channels.  The villages are built on small eminences, and are entirely surrounded with water; they have the usual form, and those houses adjoining the water have fences of an Arundo, which they tell us are intended to keep out the grass.  We have since entering these jheels passed through and between immense beds of vegetation, formed principally of Oplismenus (Panicum) stagninus, Leersia? aristata, which by-the-bye is a distinct genus. Villarsia cristata, Nymphaealotus, Potamogeton, Azolla Salvinii, etc. etc.  The only novel things we have met with are Ischaemum cuspidatum, Roxb. (sui generis,) and a small grass intermediate between Panicum and Chamaeraphis.  The wild form of Oryza sativa, Panicum interruptum and Leersia? ciliaris, Roxb. also occur; the two former in abundance.  On the more dry tracts, that occasionally though very rarely occur, Andropogon muricatus appears.  No Saccharum presented itself since the 28th.  High ground was visible yesterday evening, apparently at a great distance.

October 1st.—­We have continued to pass through immense jheels:  about 6 A.M. we arrived at Hubbe-gunge, a large native town, situated on the Barak, which does not deserve the name of a river.  The actual distance from this place to Chattuc is about 42 miles, and the high land in that direction was faintly visible for about 2 hours in the morning.  The ground to the Eastward is losing the “Jheel” character, and appears densely wooded, and to the S.E. rather high hills are visible.  Altogether this land of jheels is very remarkable, particularly on account of the great depth of the water, which except in one point has hitherto always exceeded 6 feet, and yet the water has fallen in all probability two or three more.  As the head quarters of tropical aquatic plants, it is well worthy of attention; the profusion of Leersia aristata, Roxb. is immense, but this is almost exceeded by Oplismenus stagninus.
