The trio were still discussing the particulars of the sad disaster, which, on a stormy September night, had resulted in the drowning of nearly five hundred people, and the plunging of the ship herself to the depths wherein they had so strangely found her, when the figure of the professor, clad in his suit of diving armour and dwindled in apparent dimensions by his great distance below them, was seen to emerge from the black shadow of the _Flying Fish's_ hull and make his way slowly and laboriously over the rocky bottom toward the wreck. A couple of minutes sufficed him to perform the short journey; and; scrambling up the side by the aid of some of the dangling gear, he entered the poop cabin and disappeared. The party in the pilot-house finished their chat; and then sauntered down into the music saloon, of which they had seen nothing since the night of their departure from London--actually only two nights before, but they had since then been so satiated with novel sights and experiences that it really seemed as though at least a month had elapsed since they last passed the threshold. Here they beguiled the time so effectually with music, vocal and instrumental, that it was not until George appeared announcing dinner that it occurred to either of them that the professor had been out of the ship nearly three hours. "Where can the man be? Surely some accident must have befallen him!" exclaimed the baronet, starting up in alarm. "Not necessarily," replied the colonel. "The professor is pretty well able to take care of himself. It is much more probable that he has discovered some object of exceptional interest on board the wreck, or has fallen into a scientific reverie as to the actual cause of the disaster--the cause, I mean, from a _scientist's_ point of view. Sound the gong, George; water is a good conductor, and he may possibly hear it and be awakened to a consciousness that time flies." The gong was accordingly struck, and the three companions hastened to the pilot-house to watch for results. The call proved effectual, for in less than five minutes afterwards the professor made his appearance on the deck of the wreck, soon afterwards rejoining his friends on board the _Flying Fish_ in the vestibule outside the saloons. He carried in his hand a small compact package, which he deposited carefully on the sideboard, and then, with a much more cheerful mien than he had worn when setting out upon his solitary journey, took his accustomed place at the table, apparently quite prepared to do full justice to the meal which was about to be served. The soup and fish were discussed in silence; a glass of wine was then imbibed with much apparent enjoyment, and this unlocked the professor's lips.
