"The river was exceedingly narrow about fifteen miles from our starting point this morning. The stream was strong but deep, flowing through the usual tangled grass, but divided into numerous small channels and backwaters that render the navigation difficult. "In this spot the river is quite bank-full, and the scattered native villages in the distance are in swamps. The innumerable high white ant-hills are the only dry spots. "February 24.--Started at 6 A.M. Everybody eaten up by mosquitoes. At 9 A.M. the steamer smashed her starboard paddle: the whole day occupied in repairing. Saw a bull elephant in the marshes at a distance. Horrible treeless swamps swarming with mosquitoes. "February 25.--Started at 7 A.M. At 10 A.M. arrived at a very narrow and shallow portion of this chaotic river completely choked by drift vegetation. All hands worked hard to clear a passage through this obstruction until 2.30, when we passed ahead. At 4 P.M. we arrived at a similar obstacle; the water very shallow; and to-morrow we shall have to cut a passage through the high grass, beneath which there is deeper water. I ordered fifty swords to be sharpened for the work. We counted seventy elephants in the distance, but there is no possibility of reaching them through the immense area, of floating vegetation. "February 26.--Hard at work with forty men cutting a canal about 150 yards long through the dense mass of compressed vegetation. "February 27.--Working hard at canal. The fleet has not arrived; thus we are short-handed. "February 28.--The canal progresses, the men having worked well. It is a curious collection of trash that seriously impedes navigation. The grass resembles sugar-canes; this grows from twenty to thirty feet in length, and throws out roots at every joint; thus, when matted together, its roots still increase, and render the mass a complete tangle. During the wet season the rush of water tears off large rafts of this floating water-grass, which accumulate in any favourable locality. The difficulty of clearing a passage is extreme. After cutting out a large mass with swords, a rope is made fast, and the raft is towed out by hauling with thirty or forty men until it is detached and floated down the stream. Yesterday I cut a narrow channel from above stream in the hope that the rush of water would loosen the mass of vegetation. After much labour, at 12.30 p.m. the whole obstruction appeared to heave. There was soon no doubt that it was moving, and suddenly the entire dam broke up. Immense masses were carried away by the rush of water and floated down the river; these will, I fear, cause an obstruction lower down the stream.
