clouds of hot vapour which frequently surrounded and threatened to suffocate us, obliging us to step suddenly back with wetted faces. It was fortunate that these waters contain but a very small quantity of brimstone, otherwise we could scarcely have long maintained our elevated position. The rock from which these springs rise is formed of a reddish mass, and the bed of the river into which the water flows is also completely covered with little stones of the same colour. On our way back we noticed, near a cottage, another remarkable phenomenon. It was a basin, in whose depths the water boils and bubbles violently; and near this basin are two unsightly holes, from which columns of smoke periodically rise with a great noise. Whilst this is going on, the basin fills itself more and more with water, but never so much as to overflow, or to force a jet of water into the air; then the steam and the noise cease in both cavities, and the water in the reservoir sinks several feet. This strange phenomenon generally lasts about a minute, and is repeated so regularly, that a bet could almost be made, that the rising and falling of the water, and the increased and lessened noise of the steam, shall be seen and heard sixty or sixty-five times within an hour. In communication with this basin is another, situate at a distance of about a hundred paces in a small hollow, and filled like the former with boiling water. As the water in the upper basin gradually sinks, and ceases to seethe, it begins to rise in the lower one, and is at length forced two or three feet into the air; then it falls again, and thus the phenomenon is continually repeated in the upper and the lower basin alternately. At the upper spring there is also a vapour-bath. This is formed by a small chamber situate hard by the basin, built of stones and roofed with turf. It is further provided with a small and narrow entrance, which cannot be passed in an upright position. The floor is composed of stone slabs, probably covering a hot spring, for they are very warm. The person wishing to use this bath betakes himself to this room, and carefully closes every cranny; a suffocating heat, which induces violent perspiration over the whole frame, is thus generated. The people, however, seldom avail themselves of this bath.
