"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.
"Captain Harding," said he, "I must go; I can bear the journey.I must go."Gideon Spilett approached Herbert; then, having looked at him,--"Let us go, then!" said he.
The question was quickly decided whether Herbert should be carried on a litter or in the cart which had brought Ayrton to the corral.The motion of the litter would have been more easy for the wounded lad, but it would have necessitated two bearers, that is to say, there would have been two guns less for defense if an attack was made on the road.Would they not, on the contrary, by employing the cart leave every arm free? Was it impossible to place the mattress on which Herbert was lying in it, and to advance with so much care that any jolt should be avoided? It could be done.
The cart was brought.Pencroft harnessed the onager.Cyrus Harding and the reporter raised Herbert's mattress and placed it on the bottom of the cart.The weather was fine.The sun's bright rays glanced through the trees.
"Are the guns ready?" asked Cyrus Harding.
They were.The engineer and Pencroft, each armed with a double-barreled gun, and Gideon Spilett carrying his rifle, had nothing to do but start.
"Are you comfortable, Herbert?" asked the engineer.
"Ah, captain," replied the lad, "don't be uneasy, I shall not die on the road!"While speaking thus, it could be seen that the poor boy had called up all his energy, and by the energy of a powerful will had collected his failing strength.
The engineer felt his heart sink painfully.He still hesitated to give the signal for departure; but that would have driven Herbert to despair--killed him perhaps.
"Forward!" said Harding.
The gate of the corral was opened.Jup and Top, who knew when to be silent, ran in advance.The cart came out, the gate was reclosed, and the onager, led by Pencroft, advanced at a slow pace.
Certainly, it would have been safer to have taken a different road than that which led straight from the corral to Granite House, but the cart would have met with great difficulties in moving under the trees.It was necessary, therefore, to follow this way, although it was well known to the convicts.
Cyrus Harding and Gideon Spilett walked one on each side of the cart, ready to answer to any attack.However, it was not probable that the convicts would have yet left the plateau of Prospect Heights.
Neb's note had evidently been written and sent as soon as the convicts had shown themselves there.Now, this note was dated six o'clock in the morning, and the active orang, accustomed to come frequently to the corral, had taken scarcely three quarters of an hour to cross the five miles which separated it from Granite House.They would, therefore, be safe at that time, and if there was any occasion for firing, it would probably not be until they were in the neighborhood of Granite House.However, the colonists kept a strict watch.Top and Jup, the latter armed with his club, sometimes in front, sometimes beating the wood at the sides of the road, signalized no danger.
The cart advanced slowly under Pencroft's guidance.It had left the corral at half-past seven.An hour after, four out of the five miles had been cleared, without any incident having occurred.The road was as deserted as all that part of the Jacamar Wood which lay between the Mercyand the lake.There was no occasion for any warning.The wood appeared as deserted as on the day when the colonists first landed on the island.
They approached the plateau.Another mile and they would see the bridge over Creek Glycerine.Cyrus Harding expected to find it in its place;supposing that the convicts would have crossed it, and that, after having passed one of the streams which enclosed the plateau, they would have taken the precaution to lower it again, so as to keep open a retreat.
At length an opening in the trees allowed the sea-horizon to be seen.But the cart continued its progress, for not one of its defenders thought of abandoning it.
At that moment Pencroft stopped the onager, and in a hoarse voice,--"Oh! the villains!" he exclaimed.
And he pointed to a thick smoke rising from the mill, the sheds, and the buildings at the poultry-yard.
A man was moving about in the midst of the smoke.It was Neb.
His companions uttered a shout.He heard, and ran to meet them.
The convicts had left the plateau nearly half-an-hour before, having devastated it!
"And Mr.Herbert?" asked Neb.
Gideon Spilett returned to the cart.
Herbert had lost consciousness!
