Whilst I was sketching the hills and fixing their positions, the villagers came crowding round me, and peeped from all directions at the picture I was making. When I had finished, I made the most of the opportunity by getting the head-men into the temple to make a map of the country with matches and bamboo strips on the floor. All were very good-natured, and I learned from them the position of the sources of the Meh Ping, Meh Teng, Meh Hang, Meh Pai, Meh Nium, Meh Pam, and other streams. All were intent upon my having correct information, and various villagers were sent for who had travelled in different parts of the country. After I had finished the map, Dr M‘Gilvary asked the people to listen quietly to him, and preached to them the glad tidings that the world was ruled by a God of love, and that belief in Him would relieve them from their gross fears and senseless superstitions. In the afternoon we continued through the rice-plain for a couple of miles, and then passing through the southern gate of the palisaded city of Kiang Dow, entered the city, and shortly afterwards, turning to the right, left the enclosure by the east gate, and camped for the night on the bank of the Meh Ping. A short distance before reaching the city, Dr M‘Gilvary noticed traces of what he believed to be petroleum on the bank of a small stream. In connection with this I may mention that Chow Rat, a first cousin of the Queen of Zimmé, who was intrusted with the settlement of Muang Fang, brought specimens of a black encrustation found in the district of Muang Fang, which Dr M‘Gilvary forwarded to a professor of Davidson College, North Carolina, who had it examined. It was pronounced to be indicative of rich petroleum wells. If petroleum exists at Kiang Dow as well as in Muang Fang, places 40 miles apart, the field is likely to be a large one; and other fields may be found to exist on the line of our proposed railway.
