took up the lamp. I could not help rising and following. He moved slowly along the firm and solid granite wall. I watched him with mingled curiosity and eagerness. Presently he halted and placed his ear against the dry stone, moving slowly along and listening with the most extreme care and attention. I understood at once that he was searching for the exact spot where the torrent's roar was most plainly heard. This point he soon found in the lateral wall on the left side, about three feet above the level of the tunnel floor.
I was in a state of intense excitement. I scarcely dared believe what the eider-duck hunter was about to do. It was, however, impossible in a moment more not to both understand and applaud, and even to smother him in my embraces, when I saw him raise the heavy crowbar and commence an attack upon the rock itself.
"Saved," I cried.
"Yes," cried my uncle, even more excited and delighted than myself; "Hans is quite right. Oh, the worthy, excellent man! We should never have thought of such an idea."
And nobody else, I think, would have done so. Such a process, simple as it seemed, would most certainly not have entered our heads. Nothing could be more dangerous than to begin to work with pickaxes in that particular part of the globe. Supposing while he was at work a break-up were to take place, and supposing the torrent once having gained an inch were to take an ell, and come pouring bodily through the broken rock!
Not one of these dangers was chimerical. They were only too real. But at that moment no fear of falling in of roof, or even of inundation was capable of stopping us. Our thirst was so intense, that to quench it we would have dug below the bed of old Ocean itself.

The guide, on the contrary, calm, ready, moderate, wore away the hard rock by little steady blows of his instrument, making no attempt at a larger hole than about six inches. As I stood, I heard, or I thought I heard, the roar of the torrent momentarily increasing in loudness, and at times
