's done it!"

"Being obliged to try and use it," cried Jack quickly.

"That's got something to do with it perhaps, sir, but that isn't
everything. It was that soaking last night, and then the stewing in
that hot sand. It took all the rest of the trouble away. Now then,
only let me get a chance at one of these chaps, and I'll try how he
likes arrow. I'll 'arrow his feelings a bit."

"But are you sure your arm is quite strong again?" cried Jack joyfully.

For answer Ned swung his left round the speaker's waist, lifted him from
the ground, and held him up with ease.

"What do you say to that, sir? But there, come along, I want to get
something to eat. I feel horrid, and begin to understand how it is that
some of the people out here eat one another."

"Don't keep on talking such absurd stuff, Ned," cried Jack, half
angrily, half amused; for in the early stages of suffering from hunger
there are symptoms of a weak hysterical disposition to laugh.

"But I'm so hungry, sir!"

"Well, push on, and we may get a chance at a big bird of some kind. But
suppose we should shoot one--we might--these arrows may be poisoned."

"Wouldn't matter, sir. They say cooking kills the poison. Which way
now?"

"Keep bearing to the right up the mountain, but always well within
shelter. We must not be taken again."

"Good-bye to the wild bananas that grow below," muttered Ned; and he
pressed on eagerly, but keeping a sharp look-out all the while, and
whenever an opening had to be crossed, setting the example of going down
on all fours.

"Won't do though to keep like this, sir," he said; "why, they'd shoot at
us at once for wild beasts of some kind. But do look here, sir! Ain't
it wonderful--ain't it grand? My arm feels as if it had been bottling
up all its strength, and to be readier than ever now. Oh, if we could
only see something to shoot at."

But saving small brightly-plumaged birds, they encountered nothing to
tempt the venture of an arrow, and at the end of what must have been
quite two hours, when the cave of the lava flow was left far behind, and
several hundred feet lower, Jack dropped upon his knees beside a lovely
little pool, into which trickled through the rocks and stones a
thread-like stream of the clearest water.

"No, no, sir, don't drink--it's bad. Cold water when you're hot, and on
an empty stomach."

"But I'm so thirsty, Ned, and it looks so tempting."

"I'm ever so much thirstier, sir. Look h
