I don't know who they are, sir, but it's something. Let's get
away, sir, fast as we can."

"Which way?"

"I d'know, sir, anyways as aren't near them."

"Why, it was a couple of birds of some kind."

"What! them snorky bill birds?" said Billy, alluding to the hornbills.

"Yes, I expect it was one of them, or a kingfisher."

"Birds!" said Billy in tones of disgust. "I never heerd no bird laugh
at you when you was in trouble. I'm thinking as there's things in this
here place as it wouldn't be nice to meet."

"I daresay there are, Billy; but these were birds."

"Birds! Hark at him! Would a bird shout to you to walk?"

"It didn't. It was a sort of croak."

"If we stops here I shall feel as if I'm going to croak, Mr Mark, sir.
Why, them things made me feel cold all down my back."

"Nonsense! Come, shout again!"

Billy shook his head.

"Shout, I tell you. We don't want to stop here all night."

to them. Let's get away, sir, do."

"What do you mean, then?" persisted Mark. "Do you think there are
goblins in the wood?"

"Something o' that sort, sir, but don't speak out loud. They might
hear, and not like it."

"But goblins out here wouldn't understand English," said Mark laughing;
but all the same it was rather a forced laugh, for the little sailor's
evident dread was infectious.

"I wouldn't laugh if I was you, Mr Mark, sir. Come along."

"Shout," cried Mark, ashamed of the shadow of cowardice which had begun
to envelop him, and he gave forth a loud "Ahoy!"

Ha--ha--ha!

Wauck!

The same two responses, but decidedly closer; and as Billy gripped the
lad's arm again they heard from out of the darkest part of the jungle
close by a peculiar chuckling, as if some one were thoroughly enjoying
their predicament.

"Did yer hear that?" whispered Billy, whose sun-tanned visage was now
quite pallid and mottled with muddy grey.

"Yes, I heard it, of course," said Mark, fi
