the passage. Many and many years have passed away since the return of Saknussemm, and the fall of this huge block of granite. Is it not quite evident that this gallery was formerly the outlet for the pent-up lava in the interior of the earth, and that these eruptive matters then circulated freely? Look at these recent fissures in the granite roof; it is evidently formed of pieces of enormous stone, placed here as if by the hand of a giant, who had worked to make a strong and substantial arch. One day, after an unusually heavy shock, the vast rock which stands in our way, fell through to a level with the soil and has barred our further progress. We are right, then, in thinking that this is an unexpected obstacle, with which Saknussemm did not meet; and if we do not upset it in some way, we are unworthy of following in the footsteps of the great discoverer, and incapable of finding our way to the Center of the Earth!"
In this wild way I addressed my uncle. The zeal of the Professor, his earnest longing for success, had become part and parcel of my being. I wholly forgot the past; I utterly despised the future. Nothing existed for me upon the surface of this spheroid in the bosom of which I was engulfed, no towns, no country, no Hamburg, no Königstrasse, not even my poor Gretchen, who by this time would believe me utterly lost in the interior of the earth!
"Well," cried my uncle, roused to enthusiasm by my words, "let us go to work with pick-axes, with crowbars, with anything that comes to hand—but down with these terrible walls."
"It is far too tough and too big to be destroyed by a pick-ax or crowbar," I replied.

"Gunpowder!"
"Yes; all we have to do is to get rid of this paltry obstacle."
"To work, Hans, to work!" cried the Professor. The Icelander went back to the raft, and soon returned with a
