re been a
submersion of the land, but the impression was more and more confirmed
that the very bowels of the earth must have yawned and closed again upon
a large territory. Of the rocky substratum of the province it became
more evident than ever that not a trace remained, and a new soil
of unknown formation had certainly taken the place of the old sandy
sea-bottom. As it altogether transcended the powers of those on board to
elucidate the origin of this catastrophe, it was felt to be incumbent on
them at least to ascertain its extent.

After a long and somewhat wavering discussion, it was at length decided
that the schooner should take advantage of the favorable wind and
weather, and proceed at first towards the east, thus following the
outline of what had formerly represented the coast of Africa, until that
coast had been lost in boundless sea.

Not a vestige of it all remained; from Cape Matafuz to Tunis it had all
gone, as though it had never been. The maritime town of Dellis, built
like Algiers, amphitheater-wise, had totally disappeared; the highest
points were quite invisible; not a trace on the horizon was left of the
Jurjura chain, the topmost point of which was known to have an altitude
of more than 7,000 feet.

Unsparing of her fuel, the _Dobryna_ made her way at full steam towards
Cape Blanc. Neither Cape Negro nor Cape Serrat was to be seen. The town
of Bizerta, once charming in its oriental beauty, had vanished utterly;
its marabouts, or temple-tombs, shaded by magnificent palms that fringed
the gulf, which by reason of its narrow mouth had the semblance of a
lake, all had disappeared, giving place to a vast waste of sea, the
transparent waves of which, as still demonstrated by the sounding-line,
had ever the same uniform and arid bottom.

In the course of the day the schooner rounded the point where, five
weeks previously, Cape Blanc had been so conspicuous an object, and she
was now stemming the waters of what once had been the Bay of Tunis. But
bay there was none, and the town from which it had derived its name,
with the Arsenal, the Goletta, and the two peaks of Bou-Kournein, had
all vanished from the view. Cape Bon, too, the most northern promontory
of Africa and the point of the continent nearest to the island of
Sicily, had been included in the general devastation.

Before the occurrence of the recent prodigy, the bottom of the
Mediterranean just at this point had formed a sudden ridge across th
