In the morning after breakfast I started off, but found I had four miles to walk over a wearisome straight road through coffee plantations before I could get to the forest, and as soon as I did so, it came on to rain heavily and did not cease until night. This distance to walk every day was too far for any profitable work, especially when the weather was so uncertain. I therefore decided at once that I must go further on, until I found someplace close to or in a forest country. In the afternoon my friend Mr. Bensneider arrived, together with the Controlleur of the next district, called Belang, from whom I learned that six miles further on there was a village called Panghu, which had been recently formed and had a good deal of forest close to it; and he promised me the use of a small house if I liked to go there.

The next morning I went to see the hot-springs and mud volcanoes, for which this place is celebrated. A picturesque path among plantations and ravines brought us to a beautiful circular basin about forty feet in diameter, bordered by a calcareous ledge, so uniform and truly curved, that it looked like a work of art. It was filled with clear water very near the boiling point, and emitted clouds of steam with a strong sulphureous odour. It overflows at one point and forms a little stream of hot water, which at a hundred yards' distance is still too hot to hold the hand in. A little further on, in a piece of rough wood, were two other springs not so regular in outline, but appearing to be much hotter, as they were in a continual state of active ebullition. At intervals of a few minutes, a great escape of steam or gas took place, throwing up a column of water three or four feet high.

We then went to the mud-springs, which are about a mile off, and are still more curious. On a sloping tract of ground in a slight hollow is a small lake of liquid mud, with patches of blue, red, or white, and in many places boiling and bubbling most furiously. All around on the indurated clay are small wells and craters full of boiling mud. These seem to be forming continually, a small hole appearing first, which emits jets of steam and boiling mud, which upon hardening, forms a little cone with a crater in the middle. The ground for some distance is very unsafe, as it is evidently liquid at a small depth, and bends with pressure like thin ice. At one of the smaller, marginal jets which I managed to approach, I held my hand to see if it was really as hot as it looked, when a little drop of mud that spurted on to my finger scalded like boiling water.
