The heat becomes greater and greater, the thermometer having risen to 102° Fahr. in the shade; thus hunting is now a painful, and sometimes impossible, exertion, anywhere except in the woods. A few days ago I took advantage of a short spell of cloudy, and consequently cooler weather, to visit a waterfall I had heard of in the almost desert district of Prion, twelve miles from Kombau. After reaching the last-named place, our course lay for about an hour and a half along a charming valley, nearly as smooth as a lawn, and as ornamental as a park. By and by entering a forest, we kept by the banks of a stream, which, shut in between two mountains and studded with blocks of granite, increases in size as you approach its source. Before long we arrived at the fall, which must be a fine spectacle in the rainy season. It then pours down from immense perpendicular rocks, forming as it were a circular peaked wall, nearly thirty metres in diameter, and twenty metres in height. The force of the torrent having been broken by the rocky bed into which it descends, there is another fall of ten feet; and, lower down, after a third fall of fifteen feet, it passes into an ample basin, which, like a mirror, reflects the trees and cliffs around. Even during the dry season the spring, then running from beneath enormous blocks of granite, flows in such abundance as to feed several streams. I was astonished to see my two servants, heated by their long walk, bathe in the cold water, and on my advising them to wait for a little, they replied that the natives were always accustomed to bathe when hot.

MONKEYS PLAYING WITH A CROCODILE.] We all turned stone-cutters, that is to say, we set to work to detach the impression of an unknown animal from the surface of an immense mass of granite rising up out of one of the mountain torrents. A Chinese had in January demanded so exorbitant a sum for this, that I had abandoned the idea, intending to content myself with an impression in wax, but Phrai proposed to me to undertake the work, and by our joint labour it was soon accomplished. The Siamese do not much like my meddling with their rocks, and their superstition is also somewhat startled when I happen to kill a white ape, although when the animal is dead and skinned they are glad to obtain a cutlet or steak from it, for they attribute to the flesh of this creature great medicinal virtues.
