There is always much that is mysterious about the ocean, much that we cannot understand, and creatures may exist therein that are more dreadful to behold than the wildest nightmares. It is on still, calm nights that these mysteries come up from the dark depths, so sailors will tell you. Even on the blackest nights they may give some indication of their presence. On this very cruise of the San Salvador, for instance, the men forward openly averred that the ship was followed, was "shadowed," they termed it, by some dread thing—they could not have told you what, for it had so many shapes. It was never twice seen alike. But they would have told you they always seemed to feel its presence, and knew that it was not far off even in daylight and in the sunshine.

In a fog, soon after they had got clear of the southern ice, men forward heard a fearful blowing, hissing sound on the lee bow, and soon after saw IT looming high above them almost like a black cloud. Then a plash in the water and IT was gone.

In the broad light of day once a flag had been dropped overboard. Now, it is unlucky to lose a flag, so the main-yard was hauled aback, and a whaler lowered, manned by five men. They could see the flag spread out on the water after they had rowed fully half a mile from the ship's position. They pulled fast and hard now, and soon reached it. Horror of horrors! the awful IT was near the flag, and no oar was stretched out to recover the bunting. What it was like no man could rightly say; but all agreed as to its being all legs and claws, with a beak-armed head and terror-striking eyes.

Another day a boat went after a seal that was floating on a morsel of ice. When within about two hundred yards of the little berg a very strange thing occurred. A tall, black arm, higher and thicker than a fishing-boat's mast, was slowly raised above the water, and there remained, as if to warn them not to approach. It is needless to say the boat returned without the seal.

One dark night, a long, wriggling, snake-like line of bluish fire was seen rushing along the surface of the water. All hands were called when it was no larger than a ship's lantern far away on the lee bow. All hands watched it, getting bigger and bigger as it approached. All hands saw it cross the bows in the shape I have mentioned, the men being frightened almost to death, and clutching fearfully at each other, none daring to speak or move, till finally IT disappeared as it had come, far away on the weather horizon.

And every night, when becalmed, the men were sensible of some huge dark image rolling in the water at no very great distance.

Verily there are more things in heaven and in the earth and sea, than we have dreamt of in our philosophy.

But on this particular night the men of the good barque San Salvador were far more cheerful than usual, for IT had not not appeared in any shape or form for several days. Then the stars looked so comforting and seemed so near, while away in the west lay a long bank of rock-like clouds, the profile of which could be seen every few seconds in the glare of the lightning that flashed behind it.

There was not much light on deck, however, a glimmer from the skylight, a smoking lantern forward near the forecastle, and rays from the binnacle, but not sufficient to show even the faces of three individuals who were sitting on the grating abaft. You could have noticed that two were smoking cigars, the red tips would have told you that, and the aroma of Cuba confirmed it.

"Why, sir, if this wind holds, we'll go jumping across, and get into Cape Town harbour in a fortnight's time."
