ith the aid of two sheets, a needle and thread and a few pins, Mrs.
Medford had made some very ghostly garments for the girls, fitting them
with a skill which partly revealed and partly concealed the graceful
outlines of the wearers. Eyelets had been cut, and the general effect
was indeed striking.

"But the skeletons we saw?" questioned Frank.

"A little phosphorus produced them," explained Mrs. Medford. "I drew the
skeleton outlines on the sheets with phosphorus. Of course they'll be
visible only in the dark."

"Mrs. Medford, you're a wonder!" declared Hodge. "Now we're all right.
There'll be ghosts abroad in the Adirondacks to-night."

After a general inspection of their costumes, the party prepared to
start.

"Almost wish I had decided to go," confessed Browning. "But I'll stay
here and take care of Mrs. Medford."

"If you wish to go, I can take care of her," assured Warren Hatch.

"It's too late now," said Bruce quickly. "Besides that, it's quite a
walk over there, and I'd get tired of dancing in short order. I'll stay

surface of the lake.

From far away on the southern shore came the sound of music and they
could see the gleaming lights.

"Take care of those girls, boys," called Mrs. Medford. "If anything
happens to them I'll never forgive myself for letting them out of my

"Don't worry," advised Frank. "You may rest assured that they are quite
safe in our care. We'll guard them with our lives, but there is no
possibility of danger to-night."

Little he knew what would happen before the night passed.

CHAPTER V.

THE WOLVES.

The pavilion was brilliantly lighted. Hundreds of Chinese lanterns were
suspended from the beams and cross timbers. The musicians were hidden by
an arbor of green at one end of the floor. The floor itself swarmed with
dancers wearing all sorts of grotesque and beautiful costumes.

Amid the whirling throng two ghosts were waltzing, the partner of one
being a cowboy, while the right arm of a redskin encircled the waist of
the other.

The waltzing of these couples was the poetry of grace and motion. They
seemed to glide over the floor without effort of any sort. The ease of
their movements was admired by many.

"Isn't it delightful, Frank?" enthusiastically whispered one of the
ghosts; and her cowboy pa
