nt, Turnbull would at once
seize the opportunity to institute a search for the cave; and he knew,
further, that--since the man was undoubtedly possessed of tolerably
complete information, including, probably, a map of the island--he must
sooner or later make his appearance in the neighbourhood; he therefore
selected a spot where, himself unseen, he could command a view of the
ground over which the fellow must almost inevitably pass, and sat down
to patiently await developments.

At length, after Leslie had been in ambush for nearly three hours, he
saw Turnbull approaching among the trees, carrying what appeared to be a
map or plan in his hand, which he consulted from time to time, with
frequent pauses to stare about him as though in search of certain
landmarks. As the burly ruffian drew nearer, Dick took a revolver from
his pocket and finally scrutinised it to make absolutely certain that it
was in perfect working order. Slowly the fellow approached, muttering
curses below his breath at the unevenness of the way and the
unsimilarity of the landscape with that described in the document which
he carried. Presently he went, stumbling and execrating, close past the
spot where Leslie remained concealed, and the latter at once rose to his
feet and followed him noiselessly, at a distance of some fifteen paces.
In this fashion the two men covered a distance of about a quarter of a
mile, when Turnbull once more paused to consult his map.

At the same moment Leslie halted, and, levelling his revolver at the
boatswain's head, said--

"It is no good, Turnbull; you will never find the place without my help.
No, you don't! Throw up your hands. Over your head with them, quick,
or I'll fire! Do you hear what I say, sir? Well, take that, then, you
obstinate mule, as a hint to do as you are told in future!"

And as Leslie spoke he pulled the trigger of his revolver, and sent a
bullet through the man's left arm, shattering the bone above the elbow.

For, with the sound of Dick's voice, Turnbull had faced about, and, with
a bitter curse, made as though he would plunge his hands into the
side-pockets of the pilot jacket that he was wearing. As the shot
struck him he gave vent to another curse that ended in a sharp howl of
anguish as he flung his uninjured arm above his head.

"What the blazes are ye doin' of?" he yelled in impotent fury. "D'ye
know that you've broke my arm?"

"Sorry," remarked Dick, nonchalantly, "but you _w
