yed 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 coniferae, to which, in New Zealand, the natives give the
name of 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 northwest rose Mount Franklin, which concealed
a great part of the horizon.

But Herbert, from the height of his observatory, could examine all the
yet unknown portion of the island, which might have given shelter to the
strangers whose presence they suspected.

The lad looked attentively. There was nothing in sight on the sea, not
a sail, neither on the horizon nor near the island. However, as the bank
of trees hid the shore, it was possible that a vessel, especially if
deprived of her masts, might lie close to the land and thus be invisible
to Herbe
