various points and indentations noted
on the previous day were passed, they seemed to display fresh beauties,
and Jack, full of animation, kept on calling his father's or the
doctor's attention to the manifold points of interest.

"Oh!" he cried at last, "if people only knew what they would see if they
travelled they would never care to stay at home."

"Yes," said Sir John dryly, "if they only knew."

They reached the beautiful glen at last, where the two springs--hot and
cold--sent their waters into the shadowed pool, Jack being now forward
with Edward, who, as an excuse for being well to the front in anything
fresh which might arise, made a point of keeping close behind his young
master with the glass, which he handed to him from time to time.

Now it was to sweep the sea beyond the glittering, misty edge of the
reef, where a rainbow showed brilliantly from time to time; now to look
up through a deep gash at the summit of the great volcano, which curved
upward till its crater was lost in a cloud of vapour. Every now and

And still the yacht glided on in perfect safety hour after hour, with

"Well, pigs make a short, sharp, barking noise sometimes," said the
doctor, whose attention had been taken by the man's words. "No, they're
not pigs, Jack," he said, as he brought his glass to bear well upon the
little cluster of animals running here and there among the trees, and
ending by darting down upon the sands to stare at the yacht. "Dogs, by
all that's wonderful. Here, Meadows, Bradleigh, what do you make of
these?"

"Mongrel wild dogs," said the captain, after a glance; "descendants of
some that have been left by a passing ship."

"Why, we may find cows, sheep, and goats yet," said the doctor.

"Very likely goats," replied the captain, "but I doubt whether we shall
find the others."

Every mile they passed spread fresh beauties before them, the rugg
