"Very astonishing if they are still here," replied the reporter, "but not astonishing at all if they are here no longer!"
"So you think that these people have already quitted the island?" returned Herbert.
"It is more than probable, my boy; for if their stay was prolonged, and above all, if they were still here, some accident would have at last betrayed their presence."
"But if they were able to go away," observed the lad, "they could not have been castaways."
"No, Herbert; or, at least, they were what might be called provisional castaways. It is very possible that a storm may have driven them to the island without destroying their vessel, and that, the storm over, they went away again."
"I must acknowledge one thing," said Herbert, "it is that Captain Harding appears rather to fear than desire the presence of human beings on our island."
"In short," responded the reporter, "there are only Malays who frequent these seas, and those fellows are ruffians which it is best to avoid."
"It is not impossible, Mr. Spilett," said Herbert, "that some day or other we may find traces of their landing."
"I do not say no, my boy. A deserted camp, the ashes of a fire, would put us on the track, and this is what we will look for in our next expedition."
The day on which the hunters spoke thus, they were in a part of the forest near the Mercy, remarkable for its beautiful trees. There, among others, rose, to a height of nearly 200 feet above the ground, some of those superb coniferæ, to which, in New Zealand, the natives give the name of Kauris.
