"That is not admissible," replied the engineer. "But to continue. Have you understood how Top was able to discover your retreat five miles from the cave in which I was lying?"
"The dog's instinct—" observed Herbert.
"Singular instinct!" returned the reporter; "since notwithstanding the storm of rain and wind which was raging during that night, Top arrived at the Chimneys, dry and without a speck of mud!"
"Let us continue," resumed the engineer. "Have you understood how our dog was so strangely thrown up out of the waters of the lake, after his struggle with the dugong?"
"No! I confess, not at all," replied Pencroft; "and the wound which the dugong had in its side, a wound which seemed to have been made with a sharp instrument; that can't be understood either."
"Let us continue again," said Harding. "Have you understood, my friends, how that bullet got into the body of the young peccary; how that case happened to be so fortunately stranded, without there being any trace of a wreck; how that bottle containing the document presented itself so opportunely, during our first sea-excursion; how our canoe, having broken its moorings, floated down the current of the Mercy and rejoined us precisely at the very moment we needed it; how after the ape invasion the ladder was so obligingly thrown down from Granite House; and lastly, how the document, which Ayrton asserts was never written by him, fell into our hands?"
As Cyrus Harding thus enumerated, without forgetting one, the singular incidents which had occurred in the island, Herbert, Neb, and Pencraft stared at each other, not knowing what to reply, for this succession of incidents, grouped thus for the first time, could not but excite their surprise to the highest degree.
"'Pon my word," said Pencroft at last, "you are right, captain, and it is difficult to explain all these things!"
"Well, my friends," resumed the engineer, "a last fact has just been added to these, and it is no less incomprehensible than the others!"
"What is it, captain?" asked Herbert quickly.
