Oubon and Bassac lie W.N.W. from M. Pimaï. It takes eight days in the rainy season to travel from this last town to Oubon, two more to reach Bassac. To return occupies at least double that period, the current being excessively strong. The Ménam-Moune at Pimaï is 75 metres wide in the dry season; in the rainy season it is from 6 to 7 metres in depth. There are in this district iron, lignites, and trunks of petrified trees lying on the ground, which even from a very short distance look like fallen trees in a natural state. Mgi-Poukham, inhabited by the Soués, is six days’ journey from Korat in a south-easterly direction. In the dry season the navigation of the river is impeded by sandbanks: at some points the stream is tolerably wide, but in others choked with sand. From Korat to Pimaï, on an elephant, occupies two days: from Korat to Thaison, two; to Sisapoune, two; to Josoutone, two days; to Oubon, four days; to Bassac, four. Direction E.N.E. from Korat; Poukiéau, N. of Chaiapume; Pouvienne, ten degrees E. of Chaiapume; Dong-kaïe, N.E. by E. of Chaiapume; M. Louang Prabang, N. of Chaiapume. From Chaiapume to Vien-Tiane is fifteen days’ journey on foot towards the N. and nine degrees E. M. Lôm, N.W. of Chaiapume; Petchaboune, W.N.W. of Chaiapume; Bassac, E.S.E. Bane Prom, a mountain situated in a valley nine miles across, is nearly 300 metres high. Bane Prom, a town. Menam Prom, a river nearly 2 metres deep and 40 wide, rises in M’Lôm, and empties itself in the Menam Chie, in the province of Koukhine. Bane-Rike, between Poukiéau and Kone-Sane, four geographical leagues from each place. Menam-Rike is a torrent which empties itself into the Prom. The vegetation is monotonous--everywhere resinous trees, chiefly of small size. There is a complete absence of birds; insects are in great number and variety, musquitoes and ox-flies in myriads. I suffer dreadfully from them, and am covered with swellings and blisters from their bites; and they torment our beasts so much that we sometimes fear it will drive them mad. The sensibility of the skin of the elephant is extraordinary, but these creatures are very skilful in brushing off their tormentors by means of a branch held in their trunks. I do not know what would become of me without these good and docile animals, and I cannot tell which to admire most, their patience or intelligence. From Kone-Sane to Vien-Tiane is eight good days’ journey in a north-easterly direction. To M’Lôm, four days W.N.W. To Petchaboune, four days W.S.W. To Kôrat, four days E.S.E. To Chaiapume, four days E.S.E. To Poukiéau, four days E.S.E. To Leuye, three days’ rapid travelling N.N.E. over mountains. From Kone-Sane to Koukhène, two days’ rapid journey E.S.E. From Koukhène to Chenobote, one day’s journey S.E. On the road from Kone-Sane to Leuye, near the former place, is a stream called Oué-Mouan, and a torrent, Oué-Kha.
