“Draw your daggers, gentlemen!” shouted the professor. “And be not dismayed; they and our armour are quite sufficient for our protection.”

It was perhaps just as well that the professor had sufficient presence of mind at that moment to say what he did; for his companions, though their courage had been proved a thousand times before, were now in a new and strange element to which they had scarcely had time to accustom themselves; and, moreover, the aspect of the fierce fish as they rushed forward with open jaws, disclosing their formidable teeth, was sufficiently weird and uncanny to at least momentarily dismay the stoutest heart.

Lieutenant Mildmay’s anticipation as to the intentions of the fish proved quite correct. On they came, some thirty or forty in number; and before the attacked could quite recover from their confusion they found themselves fairly in the clutches of the snake-like creatures. The attack was made with the utmost determination and ferocity, the eels twining themselves so powerfully about the bodies of their foes that it was almost impossible for the latter to move hand or foot; whilst the sharp teeth rasped strongly but ineffectually against the scales of the aethereum armour. The fight, however, though fiercely waged on the part of the assailants, was soon over, a single stroke of the keen double-edged dagger—as soon as the assailed could get their hands free—proving sufficient to instantly destroy the individual fish upon which it happened to fall. But so fierce were the eels that the conflict ended only with the slaughter of the last of them. The fish were of truly enormous size, two or three specimens measuring, as nearly as could be estimated, fully eighteen feet in length, whilst none were less than ten feet long. The tour of exploration was then completed without further adventure; the powerful electric lights of the ship enabled them to find her without difficulty the moment that they climbed up out of the depression; and they made good their return with no worse result than that of excessive fatigue due to their unwonted efforts in forcing their way through so dense a medium as water of ninety fathoms depth.

So novel an experience as theirs had that day been naturally furnished the chief topic of conversation at the dinner-table; the professor especially entertaining his companions with many interesting anecdotes of strange adventures which had happened to, and curious sights witnessed by divers at various times and places. At length, during a lull in the conversation, he said:

“There still remain two trials to which the Flying Fish must be subjected before we can say that we are fully acquainted with her powers, namely, a trial of her speed through the water when fully submerged; and a trial of her behaviour as an ordinary ocean-going ship. And these trials, I think, should—if you approve, Sir Reginald—be carried out before we do anything else.”

The baronet gave his willing assent to the professor’s proposal; and it was finally arranged that the trials, or, at all events, one of them, should take place on the morrow.

It having been arranged that early rising should be the order of the day throughout the voyage, they were aroused at seven o’clock on the following morning, and sat down to breakfast at eight prompt. By nine o’clock the meal was over, and the party, pipe or cigar in mouth, mustered in the pilot-house. Here the first thing the professor did was to produce a chart, to which, on spreading it open on the table, he called Lieutenant Mildmay’s attention, saying:

“Being a seaman by profession, you are undoubtedly the most skilful navigator of the party; and I therefore propose—with Sir Reginald’s full approval, which I have already obtained—to confide the navigation of the Flying Fish to you. Now this,”—making a pencil mark on the chart—“is our present position; and this,”—pointing to another pencil mark off Cape Finisterre, which presented the appearance of having been very carefully laid down—“is the point to which I wish you to navigate us in the first instance.”

“Very good,” said Mildmay. “I undertake the charge with pleasure. Only I must stipulate, that when making long passages you will rise to the surface occasionally, in order that I may be enabled to take the observations necessary to verify our position.”

“Of course, of course,” answered the professor. “Now, are we all ready to start?”
