On Friday, the 4th of October, we embarked in the Volturne, one of the postal packets of the Imperial Messageries of France; and three days later we landed at Marseilles, having no other care on our minds but that of our precious but erratic compass. This inexplicable circumstance tormented me terribly. On the 9th of October, in the evening, we reached Hamburg. What was the astonishment of Martha, what the joy of Gretchen! I will not attempt to define it. "Now then, Harry, that you really are a hero," she said, "there is no reason why you should ever leave me again." I looked at her. She was weeping tears of joy. I leave it to be imagined if the return of Professor Hardwigg made or did not make a sensation in Hamburg. Thanks to the indiscretion of Martha, the news of his departure for the interior of the earth had been spread over the whole world. No one would believe it--and when they saw him come back in safety they believed it all the less. But the presence of Hans and many stray scraps of information by degrees modified public opinion. Then my uncle became a great man and I the nephew of a great man, which, at all events, is something. Hamburg gave a festival in our honor. A public meeting of the Johanneum Institution was held, at which the Professor related the whole story of his adventures, omitting only the facts in connection with the compass. That same day he deposited in the archives of the town the document he had found written by Saknussemm, and he expressed his great regret that circumstances, stronger than his will, did not allow him to follow the Icelandic traveler's track into the very centre of the earth. He was modest in his glory, but his reputation only increased. So much honor necessarily created for him many envious enemies. Of course they existed, and as his theories, supported by certain facts, contradicted the system of science upon the question of central heat, he maintained his own views both with pen and speech against the learned of every country. Although I still believe in the theory of central heat, I confess that certain circumstances, hitherto very ill defined, may modify the laws of such natural phenomena. At the moment when these questions were being discussed with interest, my uncle received a rude shock--one that he felt very much. Hans, despite everything he could say to the contrary, quitted Hamburg; the man to whom we owed so much would not allow us to pay our deep debt of gratitude. He was taken with nostalgia; a love for his Icelandic home. "Farval," said he, one day, and with this one short word of adieu, he started for Reykjavik, which he soon reached in safety. We were deeply attached to our brave eider-duck hunter. His absence will never cause him to be forgotten by those whose lives he saved, and I hope, at some not distant day, to see him again.
