ge up the animal with great stones, after
which the two hunters returned to Granite House, following the beach,
which the tide had left uncovered. Herbert, wishing to surprise
Pencroft, said nothing about the "superb specimen of a chelonian"
which they had turned over on the sand, but, two hours later, he and
Neb returned with the cart to the place where they had left it. The
"superb specimen of a chelonian" was no longer there!

Neb and Herbert stared at each other first, then they stared about
them. It was just at this spot that the turtle had been left. The lad
even found the stones which he had used, and therefore he was certain
of not being mistaken.

"Well!" said Neb, "these beasts can turn themselves over, then?"

"It appears so," replied Herbert, who could not understand it at all,
and was gazing at the stones scattered on the sand.

"Well, Pencroft will be disgusted!"

"And Captain Harding will perhaps be very perplexed how to explain
this disappearance" thought Herbert.

"Look here," said Neb, who wished to hide his ill-luck, "we won't
speak about it."

"On the contrary, Neb we must speak about it," replied Herbert.

And the two, taking the cart, which there was now no use for, returned
to Granite House.

Arrived at the dockyard, where the engineer and the sailor were
working together Herbert recounted what had happened.

"Oh! the stupids!" cried the sailor, "to have let at least fifty meals
escape!"

"But, Pencroft," replied Neb, "it wasn't our fault that the beast got
away, as I tell you, we had turned it over on its back!"

"Then you didn't turn it over enough!" returned the obstinate sailor.

"Not enough!" cried Herbert.

And he told how he had taken care to wedge up the turtle with stones.

"It is a miracle, then!" replied Pencroft.

"I thought, captain," said Herbert, "that turtles, once placed on
their backs, could not regain their feet, especially when they are of
a large size?"

"That is true, my boy," replied Cyrus Harding.

"Then how did it manage?"

"At what distance from the sea did you leave this turtle?" asked the
engineer, who, having suspended his work, was reflecting on this
incident.

"Fifteen feet at the most," replied Herbert.

"And the tide was low at the time?"

"Yes, captain."

"Well," replied the engineer, "what the turtle could not do on the
sand it might have been able to do in the water. It turned over when
the tide
