That evening a telegram was sent to Ayrton, requesting him to bring from the corral a couple of goats, which Neb wished to acclimatize to the plateau.Singularly enough, Ayrton did not acknowledge the receipt of the despatch, as he was accustomed to do.This could not but astonish the engineer.But it might be that Ayrton was not at that moment in the corral, or even that he was on his way back to Granite House.In fact, two days had already passed since his departure, and it had been decided that on the evening of the 10th or at the latest the morning of the 11th, he should return.The colonists waited, therefore, for Ayrton to appear on Prospect Heights.Neb and Herbert even watched at the bridge so as to be ready to lower it the moment their companion presented himself.
But up to ten in the evening, there were no signs of Ayrton.It was, therefore, judged best to send a fresh despatch, requiring an immediate reply.
The bell of the telegraph at Granite House remained mute.
The colonists' uneasiness was great.What had happened? Was Ayrton no longer at the corral, or if he was still there, had he no longer control over his movements? Could they go to the corral in this dark night?
They consulted.Some wished to go, the others to remain.
"But," said Herbert, "perhaps some accident has happened to the telegraphic apparatus, so that it works no longer?""That may be," said the reporter.
"Wait till to-morrow," replied Cyrus Harding."It is possible, indeed, that Ayrton has not received our despatch, or even that we have not received his."They waited, of course not without some anxiety.
At dawn of day, the 11th of November, Harding again sent the electric current along the wire and received no reply.
He tried again: the same result.
"Off to the corral," said he.
"And well armed!" added Pencroft.
It was immediately decided that Granite House should not be left alone and that Neb should remain there.After having accompanied his friends to Creek Glycerine, he raised the bridge; and waiting behind a tree he watched for the return of either his companions or Ayrton.
In the event of the pirates presenting themselves and attempting to force the passage, he was to endeavor to stop them by firing on them, and as a last resource he was to take refuge in Granite House, where, the lift once raised, he would be in safety.
Cyrus Harding, Gideon Spilett, Herbert, and Pencroft were to repair to the corral, and if they did not find Ayrton, search the neighboring woods.
At six o'clock in the morning, the engineer and his three companions had passed Creek Glycerine, and Neb posted himself behind a small mound crowned by several dragon trees, on the left bank of the stream.
The colonists, after leaving the plateau of Prospect Heights, immediately took the road to the corral.They shouldered their guns, ready to fire on the slightest hostile demonstration.The two rifles and the two guns had been loaded with ball.
The wood was thick on each side of the road and might easily have concealed the convicts, who owing to their weapons would have been really formidable.
