First of all they examined the corral. There was not a trace of Ayrton. Had the unhappy man been dragged away by his former accomplices? Had he resisted, and been overcome in the struggle? This last supposition was only too probable. Gideon Spilett, at the moment he scaled the palisade, had clearly seen some one of the convicts running along the southern spur of Mount Franklin, towards whom Top had sprung. It was one of those whose object had been so completely defeated by the rocks at the mouth of the Mercy. Besides, the one killed by Harding, and whose body was found outside the enclosure, of course belonged to Bob Harvey's crew. As to the corral, it had not suffered any damage. The gates were closed, and the animals had not been able to disperse in the forest. Nor could they see traces of any struggle, any devastation, either in the hut, or in the palisade. The ammunition only, with which Ayrton had been supplied, had disappeared with him. "The unhappy man has been surprised," said Harding, "and as he was a man to defend himself, he must have been overpowered." "Yes, that is to be feared!" said the reporter. "Then, doubtless, the convicts installed themselves in the corral where they found plenty of everything, and only fled when they saw us coming. It is very evident, too, that at this moment Ayrton, whether living or dead, is not here!" "We shall have to beat the forest," said the engineer, "and rid the island of these wretches. Pencroft's presentiments were not mistaken, when he wished to hunt them as wild beasts. That would have spared us all these misfortunes!" "Yes," answered the reporter, "but now we have the right to be merciless!" "At any rate," said the engineer, "we are obliged to wait some time, and to remain at the corral until we can carry Herbert without danger to Granite House." "But Neb?" asked the reporter. "Neb is in safety." "But if, uneasy at our absence, he would venture to come?" "He must not come!" returned Cyrus Harding quickly. "He would be murdered on the road!" "It is very probable, however, that he will attempt to rejoin us!" "Ah, if the telegraph still acted, he might be warned! But that is impossible now! As to leaving Pencroft and Herbert here alone, we could not do it! Well, I will go alone to Granite House." "No, no! Cyrus," answered the reporter, "you must not expose yourself! Your courage would be of no avail. The villains are evidently watching the corral, they are hidden in the thick woods which surround it, and if you go we shall soon have to regret two misfortunes instead of one!" "But Neb?" repeated the engineer. "It is now four-and-twenty hours since he has had any news of us! He will be sure to come!" "And as he will be less on his guard than we should be ourselves," added Spilett, "he will be killed!" "Is there really no way of warning him?" Whilst the engineer thought, his eyes fell on Top, who, going backwards and forwards, seemed to say-- "Am not I here?"
