A series of low laterite hillocks spring up from the plain to the west of the city. This plain, and that to the north of the river, is inundated in places for a depth of two feet in the rains for eight and nine days at a time. Two of the hillocks serve as portions of the ramparts on the north and west sides of the city. The river rises in a plateau two days’ journey to the south-west of Kiang Tung, and its sources are separated from the Kiang Tung plain, which is 2500 feet above the sea, by Loi Kum, the Loi Peh Muang which divides the Kiang Tung State from that of Moné, a State lying to the west of the Salween. The Meh Sim, which enters the Salween, rises near the sources of the Meh Khoke; and the head of the pass, crossed by Dr Cushing in 1870, between Kiang Tung and the head-waters of the Meh Sim, is 6500 feet above the sea, or 4000 feet above the Kiang Tung plain. At the sources of the Meh Khoke, according to some Ngio Shans whom I interrogated, is the district of Muang Khon, which comprises several villages. Two days farther from Kiang Tung, down the Meh Khoke, is Muang Khoke, from which the river takes its name. Six days from Kiang Tung, still down the river, lies Muang Sat, or Muang Hsat, and a day farther Muang Khine and Wang Hung. Still lower down is Muang Tat Pow, then Muang Nyon and Ta Taung. The latter is distant four days by water from Kiang Hai, and five or six miles above the entrance of the Meh Fang into the Meh Khoke. The above Muangs, or provincial States, are situated in extensive plains, and Muang Sat has frequently formed the base of Burmese operations against Siam. As Muang Sat has been incorporated by us in the dominions of the chief of Muang Pan, one of our Shan States lying to the west of the Salween, it will be seen that we have already carried our protection over the hills which divide the waters of the Salween from those of the Meh Kong into the valley of the Meh Khoke. Above Ta Taung the valley of the Meh Khoke lies in the British Shan States. From thence eastwards, half-way to Kiang Hai, the Meh Khoke forms the Anglo-Siamese boundary; the frontier then turns in a north-eastern direction to the Meh Kong, which it reaches a few miles above Kiang Hsen. To the east of Loi Peh Muang[3] the people are known to the Zimmé Shans as Tai Ngio, and pertain to the Shan States west of the Salween. The chief of Moné had rebelled against the Burmese in 1882, and taken refuge with the chief of Kiang Tung: this may account for so many Ngios having recently occupied the deserted country lying to the north of Kiang Hsen. The chief of Moné has since been reappointed to his State by the British. [Illustration: _View up the Meh Khoke from the Sala at Kiang Hai._ ]
