ko, who just at dusk had come
stealing back out of the jungle, and kept close to him and out of Billy
Widgeon's reach.

Weary as he was, Mark found it a difficult task to go to sleep. Nothing
could have been more comfortable than his bed, the soft dry sand fitting
in to his shape so as to give rest to his tired muscles, and the
pleasantly cool night breeze that floated through the leaves of the tall
palms breathed upon his sun-scorched cheeks. Now and then there was the
hum of mosquitoes, but they did not molest him; and as he lay listening
to the distant boom of the surf and watched the great twinkling stars he
now and then nearly lost consciousness, and the tall columns of the
cocoa-nut trees took the shape to him of the supports of the old
four-post bedstead at home.

Then he would start into wakefulness again and listen, fancying that he
heard rustling sounds from the jungle inland, and as he raised his head

But all was silent, and he was obliged to confess that it was fancy as

the one side and the darker sky over the mountain a few miles away.

The stars shone very brightly here, too, and every now and then there

but now and then there was a flash which seemed as if the sky opened and
displayed the shapes of the clouds, and these were like mountains, or
might be the mountains themselves as far as he could tell.

Still sleep would not come, and he turned again and again till he grew
more hot and weary, and began to think at last how delightful it would
be to go down to the edge of the sea, undress, and bathe in the cool
sparkling water.

Very nice, but there were drawbacks. He did not know what strange
creatures might be roaming about in search of prey, and he had often
read that the lagoons about the tropic islands were infested with
sharks.

Then he began to think over their future in this strange place, not with
any feeling of dread, for there was a delightful novelty in the idea of
exploring this unknown island; of building their own houses, maki
