"What is the matter with Dingo?" asked Mrs. Weldon.

"We must, indeed, find out," replied the novice. "Perhaps it is Negoro
coming back."

At once Hercules, Bat, Austin, and Dick Sand took their way to the
mouth of the river.

But, arrived at the bank, they neither saw nor heard anything. Dingo
now was silent.

Dick Sand and the blacks returned to the grotto.

The going to sleep was organized as well as possible. Each of the
blacks prepared himself to watch in turn outside. But Mrs. Weldon,
uneasy, could not sleep. It seemed to her that this land so ardently
desired did not give her what she had been led to hope for, security
for hers, and rest for herself.
