"Very astonishing if they are still here," replied the reporter, "but not astonishing 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; at least, they were what might be called temporary castaways. It is very possible that a storm may have driven them to the island without 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 whom 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, which, in New Zealand, the natives call Kauris.
"I have an idea, Mr. Spilett," said Herbert. "If I were to climb to the top of one of these kauris, I could survey the country for an immense distance round."
"The idea is good," replied the reporter; "but could you climb to the top of those giants?"
"I can at least try," replied Herbert.
The light and active boy then sprang on the first branches, the arrangement of which made the ascent of the kauri easy, and in a few minutes he arrived at the summit, which emerged from the immense plain of verdure.
From this elevated situation his gaze extended over all the southern portion of the island, from Claw Cape on the southeast, to Reptile End on the southwest. To the north-
