much less intense light of the Sun; partly, perhaps,
to that absorption of the blue rays by the atmosphere,
which diminishes, I suppose, even that light which
actually reaches the planet. But uncultivated
ground, except on the mountains above the ordinary
range of crops or pastures, scarcely exists in the
belt of Equatorial continents; the turf itself, like
the herbage or fruit shrubs in the fields, is artificial,
consisting of plants developed through long ages into
forms utterly unlike the native original by the skill
and ingenuity of man. Even the great fruit trees
have undergone material change, not only in the size,
flavour, and appearance of the fruits themselves,
which have been the immediate object of care, but,
probably through some natural correlation between,
the different organs, in the form and colour of the
foliage, the arrangement of the branches, and the
growth of the trunk, all of which are much more regular,
and, so to speak, more perfect, than is the case either
here or on Earth with those left to the control of
Nature and locality, or the effects of the natural
competition, which is in its way perhaps as keen among
plants and animals as among men. Martialists have
the same delight in bright colours as Orientals, with
far greater taste in selection and combination; and
the favourite hues not only of their flowers, tame
birds, fishes, and quadrupeds, but of plants in whose
cultivation utility has been the primary object, contrast
signally, as I have said, with the dull tints of the
undomesticated flora and fauna, of which comparatively
scanty remnants were visible here and there in this
rich country.
Presently we came within sight of the river, over
which was a single bridge, formed by what might be
called a tube of metal built into strong walls on
either bank. In fact, however, the sides were
of open work, and only the roof and floor were solid.
The river at this, its narrowest point, was perhaps
a furlong in breadth, and it was not without instinctive
uneasiness that I trusted to the security of a single
piece of metal spanning, without even the strength
afforded by the form of the arch, so great a space.
The first object we were to visit lay at some distance
down the stream. As we approached the point,
we passed a place where the river widened considerably.
The main channel in the centre was kept clear and
deep to afford an uninterrupted course for navigation;
but on either side were rocks that broke the river
into pools and shallows, such as here, no less than
on Earth, form the favourite haunts or spawning places
of the fish. In some of the lesser pools birds
larger than the stork, bearing under the throat an
expansible bag like that of the pelican, were seeking
for prey. They were watched and directed by a
master on the shore, and carried to a square tank,
fixed on a wheeled frame not unlike that of the ordinary
carriage, which accompanied him, each fish they took.
I observed that the latter were carefully seized,
