The country already grew more open, and we gradually lost sight of the glaciers. The high mountains on the left seemed like hills in the distance, and the nearer ones were really hills. After riding about nine miles we crossed the large stream of Elvas in a boat, and then had to tread carefully across a very long, narrow bank, over a meadow which was quite under water. If a traveller had met us on this bank, I do not know what we should have done; to turn round would have been as dangerous as to sink into the morass. Fortunately one never meets any travellers in Iceland. Beyond the dyke the road runs for some miles along the mountains and hills, which all consist of lava, and are of a very dark, nearly black colour. The stones on these hills were very loose; in the plain below many colossal pieces were lying, which must have fallen down; and many others threatened to fall every moment. We passed the dangerous spot safely, without having had to witness such a scene. I often heard a hollow sound among these hills; I at first took it for distant thunder, and examined the horizon to discover the approaching storm. 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.
