The Meh Li flows from the south through a very picturesque and well-wooded country. Near its source, not far from the silver-mines, is a gorge or gap in the hills leading into the valley of the Meh Phit. Through this gorge a branch railway might be constructed to connect Raheng with Lapoon and Zimmé. The branch might be continued from Zimmé past Muang Ken and Kiang Dow _viâ_ the Meh Pam into the valley of the Meh Fang, whence it could be carried across the Meh Khoke through Muang Ngam into the Meh Chun valley, where it would again join the main line in the plain of Kiang Hsen. The best caravan-route between Raheng and Zimmé passes through the gap. Nearly opposite the mouth of the Meh Li is a fine monastery called Wat Ta Sala, after the _sala_, “traveller’s rest-house,” that has been erected a little higher up the river, and a little beyond, at the village of Fang Min, we passed three large spider undershot water-wheels. The axle or boss of each wheel was of hard wood, about 3 feet long and 5 inches in diameter. From this radiated two rows, about 2 feet apart, of spokes from 10 to 12 feet long. The two rows were joined together at the top by paddles made of bamboo matting, 2 feet broad by 1 foot deep. The spokes, each formed of one-third of a split bamboo, were connected together at the periphery of the wheel by a light lattice-work formed of strips of bamboo, on the under side of which were fastened joints of bamboo about 1 foot long to serve as buckets to bring up the water. The lower part of the wheel was immersed for 3 feet in the current, and the water was emptied into a trough near the top, from whence it was conveyed to the gardens and fields. The boss of the wheel worked upon two light trestles made of wood. The wheel was so light that it required little current to set it in motion. I passed 220 of these spider-web wheels between Ta Sala and Zimmé. Similar water-wheels are found in the Chinese provinces of Kweichau and Ssuchuan, as well as in Upper Burmah and the Shan States. They are used for pounding and grinding rice as well as for irrigation, and lifting water for household purposes. It is a singular spectacle to watch several of these wheels, placed within a few feet of each other, in ceaseless motion, their shafts humming loudly, and the water splashing and sparkling all over them. Just above Fang Min, between it and the monastery of Ban Dong, which lies on the east of the river, favoured by a long stretch of the river which enabled me to see over the tops of the trees lining the banks, I caught sight of the Loi Hoo-a Soo-a, “the mountain of the tiger’s head,” so called from the aspect of a precipice on its western extremity. Beyond it, twenty miles distant to the north-west, lay Loi Pah Kung, an undulating hill or plateau of great height, a monarch among the mountains, forming part of the main range of the Zimmé hills.
