"Whatever can this be?" she asked in mystified tones. Miss Judy was not
in the tent.

"Open it," commanded Agony.

Sahwah slit the envelope with the knife that she always kept hanging at
her belt, and pulled out a sheet of rough, brown paper, on which was
drawn the picture of a girl bound fast to a tree by ropes that went
round and round her body, while a band of Indians danced a savage war
dance around her. Underneath was printed in the same large red letters
as those which adorned the outside of the envelope:

BE DOWN ON THE DOCK AT SUNDOWN
WITHOUT FAIL PREPARED TO UNDERGO
THE ORDEAL WHICH ALL
DWELLERS IN THE ALLEY MUST
SUFFER BEFORE BEING WELCOMED
INTO THE INNER
CIRCLE OF ALLEY
SPIRITS.

WARNING: MENTION NOT THIS SUMMONS
TO A LIVING SOUL OR AWFUL
WILL BE THE CONSEQUENCES.

SIGNED: THE TERRIBLE TWELVE.
P.S. BRING YOUR BATHING SUITS.

"What on earth?" cried Hinpoha in bewilderment.
