The territory of Womla may be divided into three zones, namely, a
central plain under cultivation, a belt of undulating hills, kept as a
park or pleasaunce, and a magnificent, nay, a sublime wilderness, next
to the crater wall.

The natural wealth of the country is very great. Some of its productions
resemble and others are different from those of the earth. We saw gold,
silver, copper, tin, and iron, as well as metals which were quite new to
us. Some of these had a purple, blue, or green colour, and emitted a
most agreeable fragrance. There are granites and porphyries, marbles and
petrifactions of the most exquisite grain or tints. Precious stones like
the diamond, ruby, sapphire, topaz, emerald, garnet, opal, turquoise,
and others familiar or unfamiliar to us, fairly abound, and can be
picked up on the shores of the lake. I presume that many of them have
been formed on a large scale in chasms of the rock by the volcanic fumes
of the crater.

What struck us most of all, however, was the prevalence of
phosphorescent minerals which absorbed the sunlight by day, and
glimmered feebly in the dusk. Professor Gazen seems to think that the
presence of snow and clouds, together with these phosphorescent bodies,
may help to account for the mysterious luminosity on the dark side of
Venus.

The vegetation is wonderfully rich, varied, and luxuriant. As a rule,
the foliage is thick and glossy; but while it is green to blackness in
some of the trees, it is parti-coloured or iridescent in others. Many of
the flowers, too, are iridescent, or change their hues from hour to
hour. The beauty and profusion of the flowers is beyond conception, and
some of the loveliest grow on what I should take for palms, ferns,
