The bellows, two on each side of the charcoal fire, consisted each of a slightly sloping bamboo four inches in diameter, rising two feet from the ground, with a rag-covered piston working inside it and forcing the air out of a small hole. Each pair was placed three feet apart, and worked by a lad. There is a dip in the plateau near the village where paddy is grown on a slip of land about two miles long and 150 feet broad. It is irrigated by small springs, the water being led to the fields through bamboo pipes. CHAPTER VI.

Leaving Bau, we continued along the undulating plateau for two and a half miles through the pine-forests, shallow valleys at times commencing on either side. After passing some springs and large white-ant hills, and catching a glimpse of Loi Pah Khow, a great dome-shaped hill ten miles distant to the north, we came to the edge of the plateau, where a great trough or undulation separates it from Loi Kom, the Golden Mountain. Through this pass, which is about 1000 feet lower than the Bau plateau, I consider a railway might be carried from Maing Loongyee to Zimmé. Loi Kom stands considerably higher than the Bau plateau, or appeared to do so. Looking sideways across the valley, the hill resembles a very long roof sloped at the ends as well as at the sides. This mountain forms a link in the Zimmé chain of hills, and is the seat of the celebrated Lawa Yak or “genius” Poo-Sa, whose wife Ya-Sa inhabits Loi Soo Tayp, the great hill behind the city of Zimmé.
