question. I ask
Captain Harding if he sees anything supernatural in all this."

"I cannot say, Pencroft," said the engineer. "That is all the answer I
can make."

A reply which did not satisfy Pencroft at all. He stuck to "an
explosion," and did not wish to give it up. He would never consent
to admit that in that channel, with its fine sandy bed, just like
the beach, which he had often crossed at low water, there could be an
unknown rock.

And besides, at the time the brig foundered, it was high water, that is
to say, there was enough water to carry the vessel clear over any rocks
which would not be uncovered at low tide. Therefore, there could not
have been a collision. Therefore, the vessel had not struck. So she had
blown up.

And it must be confessed that the sailor's arguments were reasonable.

Towards half-past one, the colonists embarked in the boat to visit the
wreck. It was to be regretted that the brig's two boats had not been
saved; but one, as has been said, had gone to pieces at the mouth of the
Mercy, and was absolutely useless; the other had disappeared when the
brig went down, and had not again been seen, having doubtless been
crushed.

The hull of the "Speedy" was just beginning to issue from the water.
The brig was lying right over on her side, for her masts being broken,
pressed down by the weight of the ballast displaced by the shock, the
keel was visible along her whole length. She had been regularly turned
over by the inexplicable but frightful submarine action, which had been
at the same time manifested by an enormous water-spout.

The settlers rowed round the hull, and in proportion as the tide went
down, they could ascertain, if not the cause which had occasioned the
catastrophe, at least the effect produced.

Towards the bows, on both sides of the keel, seven or eight feet from
the beginning of the stem, the sides of the brig were frightfully torn.
Over a length of at least twenty feet there opened two large leaks,
which would be impossible to stop up. Not only had the copper sheathing
and the planks disappeared, reduced, no doubt, to powder, but also the
ribs, the iron bolts, and treenalls which united them. From the entire
length of the hull to the stern the false keel had been separated with
an unaccountable violence, and the keel itself, torn from the carline in
several places, was split in all its length.

"I've a notion!" exclaimed Pencroft, "that this vessel will be difficult
