Having made a raft from wood taken from the giant mushroom
with rigging consisting of a mast made of two staves lashed
together, a yard made of a third, and a sail borrowed from
stock of rugs, they set sail from the harbour - Port Grauben,
named after Axel's fiancee. With a north-westerly wind
them along at about three miles an hour, silvery beams of
reflected here and there by drops of spray, produced luminous
points in the eddy created by the raft. Soon all land was lost
view. Five days out to sea, they witnessed a terrifying battle
between two sea monsters. One having the snout of a porpoise,
head of a lizard, and teeth of a crocodile - an Ichthyosaurus.
the other, the mortal enemy of the first, a serpent with a
turtle's shell, the Plesiosaurus.
