ong," for its nostrils were
open at the upper part of its snout. The enormous animal rushed on the
dog, who tried to escape by returning towards the shore. His master
could do nothing to save him, and before Gideon Spilett or Herbert
thought of bending their bows, Top, seized by the dugong, had
disappeared beneath the water.

Neb, his iron-tipped spear in his hand, wished to go to Top's help, and
attack the dangerous animal in its own element.

"No, Neb," said the engineer, restraining his courageous servant.

Meanwhile, a struggle was going on beneath the water, an inexplicable
struggle, for in his situation Top could not possibly resist; and
judging by the bubbling of the surface it must be also a terrible
struggle, and could not but terminate in the death of the dog! But
suddenly, in the middle of a foaming circle, Top reappeared. Thrown in
the air by some unknown power, he rose ten feet above the surface of the
lake, fell again into the midst of the agitated waters, and then soon
gained the shore, without any severe wounds, miraculously saved.

Cyrus Harding and his companions could not understand it. What was not
less inexplicable was that the struggle still appeared to be going on.
Doubtless, the dugong, attacked by some powerful animal, after having
released the dog, was fighting on its own account. But it did not last
long. The water became red with blood, and the body of the dugong,
emerging from the sheet of scarlet which spread around, soon stranded on
a little beach at the south angle of the lake. The colonists ran towards
it. The dugong was dead. It was an enormous animal, fifteen or sixteen
feet long, and must have weighed from three to four thousand pounds. At
its neck was a wound, which appeared to have been produced by a sharp
blade.

What could the amphibious creature have been, who, by this terrible
blow had destroyed the formidable dugong? No one could tell, and much
interested in this incident, Harding and his companions returned to the
Chimneys.

Chapter 17

The next day, the 7th of May, Harding and Gideon Spilett, leaving Neb to
prepare breakfast, climbed Prospect Heights, while Herbert and Pencroft
ascended by the river, to renew their store of wood.

The engineer and the reporter soon reached the little beach on which the
dugong had been stranded. Already flocks of birds had attacked the mass
of flesh, and had to be driven away with stones, for Cyrus wished to
keep the fat for the
