volumes of thick white smoke. The general colour of the whole 

 was red and fiery with bluish spots and stains on the sides, as if 

 gunpowder had been recently exploded there. But what gave a 

 singular and startling appearance to the scene was three lakes in 

 the bottom of the crater, one in the centre, and the other two at 

 the sides. The centre lake was a greenish-blue like the ocean, 

 and surrounded by a broken crater of reddish-purple scorife. 

 There was a confused group of half a dozen broken craters and 

 one great slope encircling half of them. On the north side there 

 was a bright emerald green patcli like a pond covered with duck- 

 weed, except that its tint was more vivid than the greenest of 

 green waters. This was succeeded to the north-west by another 

 lake or rather a marshy flat of lemon yellow colour, which 

 deepened on its edges into a golden colour, with great orange stains 

 in places. The eastern and highest side of the crater wall was 

 yellow with sulphur, and all this side was emitting thin jets of 

 sulphurous fumes from cracks and crevices. Indeed most of the 

 walls of the inside were emitting the same fumes. Close below 

 where I stood there was a little jet of sulphur smoke, and on 

 digging down with the iron point of an alpenstock, the ground 

 around was found to be intensely hot. 



The slope of the crater on the east side was a very moderate 

 inclination, rendering a descent into it comparatively easy. 

 Accompanied with two natives as guides, I descended easily to 

 the bottom of the basin. The ground was firm and composed of 

 a mass of broken cinders, but there was evidence that at no great 

 depth these deposits were scarcely cool, as from the cracks and 

 crevices sulphurous fumes were emitted. The yellow tint of 

 sublimed sulphur was on everything. 



I made my way first of all to the bluish-green lake in the centre. 

 The rocks were exceedingly rough and scoriaceous, forming walls 

 round one portion of the waters which afi"orded no foothold, but 

 were quite precipitous. I found it very difiicult to obtain samples 

 of the water, but by means of a bamboo with which we were 

 provided, and a sodawater bottle, this was accomplished. I next 

 turned my attention to the green lake, and found the same kind
