t, and flew swiftly over three thousand miles
of ocean till they came to another island not quite as large as the
first. It was four thousand five hundred miles long by something less
than three thousand wide, and was therefore about the size of Africa.
It had several high ranges of mountains and a number of great rivers
and fine harbours, while murmuring, bubbling brooks flowed through its
forest glades. There were active volcanoes along the northern coast,
and the blue, crimson, and purple lines in the luxuriant foliage were
the most beautiful they had ever seen.

"I propose," said Bearwarden, "that we christen this Sylvialand." This
Cortlandt immediately seconded, and it was so entered on the charts.

"These two islands," said Bearwarden, "may become the centres of
civilization. With flying machines and cables to carry passengers and
information, and ships of great displacement for the interchange of
commodities, there is no limit to their possible development. The
absence of large waves will also be very favourable to sea-spiders,
which will be able to run at tremendous speeds. The constancy in the
eruptions of the volcanoes will offer a great field to Jovian
inventors, who will unquestionably be able to utilize their heat for
the production of steam or electricity, to say nothing of an
inexhaustible supply of valuable chemicals. They may contain the means
of producing some force entirely different from apergy, and as superior
to electricity as that is to steam. Our earthly volcanoes have been
put to slight account because of the long intervals between eruptions."

After leaving Sylvialand they went westward to the eastern of the two
crescent continents. It was separated from the island by about six
thousand miles of ocean, and had less width than the western, having
about the proportions of a three-day crescent, while the western had
the shape of the moon when four or five days old. They found the
height of the mountains and plateaus somewhat less than on the eastern
continent, but no great difference in other respects, except that, as
they went towards the pole, the vegetation became more like that of
Scotland or a north temperate region than any they had seen. On
reaching latitude fifty they again came out over the ocean to
investigate the speckled condition they had observed there. They found
a vast archipelago covering as great an area as the whole Pacific
Ocean. The islands varied from the size o
