“Neb has sent him to us,” said the reporter.

“Then,” replied the engineer, “he must have some note on him.”

Pencroft rushed up to the orang. Certainly if Neb had any important matter to communicate to his master he could not employ a more sure or more rapid messenger, who could pass where neither the colonists could, nor even Top himself.

Cyrus Harding was not mistaken. At Jup’s neck hung a small bag, and in this bag was found a little note traced by Neb’s hand.

The despair of Harding and his companions may be imagined when they read these words:—

“Friday, six o’clock in the morning.

“Plateau invaded by convicts.

“Neb.”

They gazed at each other without uttering a word, then they re-entered the house. What were they to do? The convicts on Prospect Heights! that was disaster, devastation, ruin.

Herbert, on seeing the engineer, the reporter, and Pencroft re-enter, guessed that their situation was aggravated, and when he saw Jup, he no longer doubted that some misfortune menaced Granite House.
