He had no idea of the time, to his great chagrin, for in his haste to
obey the forged summons to the flying track he had forgotten to bring his
watch. In fact, in his hurry, he had slipped into an old coat, the
pockets of which contained nothing more useful to him than a packet of
chewing gum. He slipped a wad of this into his mouth to "keep him
company" as he expressed it to himself, and grittily went forward.

The wood ended presently, and he found himself in a field with woods on
all three sides, except that on which the swamp impinged. Little as he
liked the idea of plunging into pathless woods, with nothing to guide him
but the stars, as he glimpsed them through the trees, there was no help
for it. Go on he must. Crossing the field rapidly he soon reached the
border of the tangle and entered its black shadows. Keeping as straight a
line as he could he hastened forward, and to his great delight, soon saw
that the trees were beginning to thin out, and that beyond lay,

"Hooray, I'm bound to strike a road before long now," thought Roy

He had not gone more than a few paces, however, when through the trees he

Gradually, as he stood still among the trees, the sound drew closer.

"Ghosts in story books always clank chains," thought Roy, to himself.
"Now if I believed in such things, I----"

He stopped short abruptly, as, from behind a clump of brush in the
direction from whence the clanking had proceeded, there suddenly emerged
a tall form all in white.

"Good gracious!" cried Roy, considerably startled by the sight of this
sudden apparition. "I do believe----"

But at the sight of the white form he had involuntarily given a backward
step. Without the slightest warning he felt the ground suddenly give way
under his feet, and his body shot down through space.

Down, down he shot, a hundred mad thoughts twisting dizzily in his head.

All at once his progress was arrested. Before he could realize what had
happened he felt a flood of icy cold water close over his head and a
mighty ringing and roaring in his ears.

But Roy was used to diving, and he automatically, almost, held his breath
till he shot to the surface again. Then he extend
