But when I saw neither clouds nor lightning, I perceived that I must seek the origin of the sounds nearer, and that they proceeded from the falling portions of rock.
The higher mountains to the left fade gradually more and more from view; but the river Elvas spreads in such a manner, and divides into so many branches, that one might mistake it for a lake with many islands.

It flows into the neighbouring sea, whose expanse becomes visible after surmounting a few more small hills.
The vale of Reikum, which we now entered, is, like that of Reikholt, rich in hot springs, which are congregated partly in the plain, partly on or behind the hills, in a circumference of between two and three miles.
When we had reached the village of Reikum I sent my effects at once to the little church, took a guide, and proceeded to the boiling springs.

I found very many, but only two remarkable ones; these, however, belong to the most noteworthy of their kind.

The one is called the little Geyser, the other the Bogensprung.
The little Geyser has an inner basin of about three feet diameter.

The water boils violently at a depth of from two to three feet, and remains within its bounds till it begins to spout, when it projects a beautiful voluminous steam of from 20 to 30 feet high.
At half-past eight in the evening I had the good fortune to see one of these eruptions, and needed not, as I had done at the great Geyser, to bivouac near it for days and nights.
