g bats, owls and all sorts of flying nocturnal
creatures. The side walls had been covered with gorgeous autumn foliage,
palms and potted rubber plants stood all about, and last, but by no means
least, there was a long table laden with goodies and more pumpkin
decorations. The room was a fitting scene for goblin's revels.

A barn dance had just begun, when down through the gym pranced
Tweedle-dum _and_ Tweedle-dee, and so identical were the figures that no
mortal being could have told one from the other had they chanced to
become separated. But this they seemed to have no intention of doing.
Together they went through the figures of the pretty fancy dance,
prancing, twirling, advancing, retreating; arms clasped or held above
each other's heads, feet twinkling in perfect time, heads nodding, eyes
dancing through the peepers of their little black half-masks, lips
smiling to reveal faultless teeth.

In two minutes everybody was asking:

"Who _is_ it? Who _are_ they? How _can_ they look so exactly alike? We
didn't know there were two girls in the school who matched so well, and
who could do everything so exactly alike."

But neither Tweedle-dum nor Tweedle-dee enlightened the questioners.
Indeed, neither spoke one word, signs having to answer to all queries.

Presently the musicians struck up a hornpipe, when away they went in the
jolliest dance eyes ever looked upon, and would have absorbed all
attention had not a new diversion been created just then.

During their prancing, Sally, in her Will-o'-the-Wisp costume, had been
darting in and out between the tall potted plants and bowers constructed
of Autumn leaves, her luminous tatters fluttering and her dancing light
blinding every dancer into whose face she flashed it.

Just as Tweedle-dum and Tweedle-dee were in the height of their
performance she darted from her bosky nook and flitted down the room,
closely followed by a tall Jack o' Lantern with his pumpkin light. No one
in the room was so tall. Who could it be? There was just one person in
the school who might look as tall if so disguised and that was Miss
Stetson, but even the liveliest imagination could hardly fancy Miss
Stetson in that guise. Moreover, Miss Stetson could never have pranced
with such supple grace as this dancing Jack was prancing after the
Will-o'-the-Wisp. No, it could not be Miss Stetson.

Towering above the nimble little Will, Jack cavorted, swung his lantern
and by signs indicated his desir
