t as did the enchanters of old in the books of
chivalry, darkening the water with the ink stored in their glands.

Ferragut continued to pass slowly along the Aquarium between the two
rows of vertical tanks,--stone cases with thick glass that permitted
full view of the interior. The clear and shining walls that received
the fire of the sun through their upper part, spread a green reflection
over the shadows of the corridors. As they made the rounds, the
visitors took on a livid paleness, as though they were marching through
a submarine defile.

The tranquil water within the tanks was scarcely visible. Behind the
thick glass there appeared to exist only a marvelous atmosphere, an air
of dreamland in which drifted up and down various floating beings of
many colors. The bubbles of their respiration was the only thing that
announced the presence of the liquid. In the upper part of these
aquatic cages, the luminous atmosphere vibrated under a continual spray
of transparent dust,--the sea water with air injected into it that was
renewing the conditions of existence for these guests of the Aquarium.

Seeing these revivifying streams, the captain admired the nourishing
force of the blue water upon which he had passed almost all his life.

Earth lost its pride when compared with the aquatic immensity. In the
ocean had appeared the first manifestations of life, continuing then
its evolutionary cycle over the mountains which had also come up from
its depths. If the earth was the mother of man, the sea was his
grandmother.

The number of terrestrial animals is most insignificant compared with
the maritime ones. Upon the earth's surface (much smaller than the
ocean) the beings occupy only the surface of the soil, and an
atmospheric canopy of a certain number of meters. The birds and insects
seldom go beyond this in their flights. In the sea, the animals are
dispersed over all its levels, through many miles of depth multiplied
by thousands and thousands of longitudinal leagues. Infinite quantities
of creatures, whose number it is impossible to calculate, swim
incessantly in all the strata of its waters. Land is a surface, a
plane; the sea is a volume.

The immense aquatic mass, three times more salty than at the beginning
of the planet, because of a millennarian evaporation that has
diminished the liquid without absorbing its components, retains mixed
with its chlorides, copper, nickel, iron, zinc, lead, and even gold,
from th
