THIRTLETH EPISODE
BEHIND THE WATER DOOR.

Del Mar made his way cautiously
along the bank of little river at the
mouth of which he left the boat, after
escaping from the little steamer.
Quite evidently he was worried by
the failure to cut the great Atlantic
cable, and he was eager to see wheth-
er any leak had occurred in the or
ganization which, as secret foreign
agent he had SO carefully built up in
America
AS he skrted the shore of the
river, he came to a falls. Here he
moved even more cautiously than be-
fore, looking about to make certain
that no one had followed him.
1t was a beautiful sheet OF water
that tumbled with a roar over the
ledge of rock, then raced away swift
ly to the sea in cloud of spray
Assured that he was alone, he ap-
preached a crevice in the rocks, near
the falls. With another hasty look
about, he reached in and pulled a
lever.
Instantly most marvellous change
took place, incredible almost beyond
belief. The volume of water that came
over the falls actually and rapidly de-
creased until it almost stopped, drip
ping slowly in thin veil. There was
the entrance of a cave-literally hid
den behind the falls.
Del Mar walked in. Inside was the
entrance to another, inner cave, high
er up in the sheer stone of the wall
that the waters had eroded. From the
fnnr fn MT cd lad
Del Mar climbed it. then stopped just
inside the entrance to the inner cave.
For a moment he paused. Then he
pressed another lever. Almost imme-
diately the thin trickle of water grew
until at last the roaring falls complete
ly covered the cave entrance. 1t was
clever concealment, contrived by
damming the river above and arrang-
ing a new outlet controlled by flood
gates.
There Del Mar stood, in the inner
cave. A man sat at table, a curious
gear fastened over his head and cover
ing his ears Before him was a huge
apparatus from which flared a big
bluish-green spark. swapping and
cracking above the thunder of the
wires apparently up through cables
that penetrated the rocky roof of the
cavern and the river above.
1t was Del Mars secret wireless
station, close to the hidden submarine
harbor which had been established be-
meath the innocent rocks of the prom
ontory up the coast. Far overhead.
on the cliff over the falls, were the
antennae of the wireless.
How is she working?" asked Del
Mar.
Pretty WE'LL" answered the man.
mo interference queried Del Mar,
adjusting the apparatus.
The man shook his head in the mega
tive
We must get a quenched spark ap-
paratus," went on Del Mar, pleased
that nothing was wrong here. This
rotary gap affair is out of date. BY
the way. l want you to be ready to
send a message, to be relayed across
to our people. I've got to consult the
board below in the harbor first, how
ever. I'll send messenger to you"
Very well, SIR" returned the man,
saluting as Del Mar went out.
Out at Fort Dale, Lieutenant Wood
ward was still entertaining his new
friend, Professor Arnold. and had in
troduced him to Colonel Swift. the
commanding officer at the fort.
They were discussing the strange
events of the early morning, when an
orderly entered. saluted Colonel Swift
and handed him a telegram The
colonel tore it open and read 1t, his
face growing grave. Then he handed
1t to Woodward. who read;
