d her eyes and only opened them when she found that
she was stationary again. She had no idea of where she was, nor of how
far she had fallen.

"Bob?" she called timidly at first, and then in terror. "Bob!"

"Look behind you," said Bob's familiar voice.

Betty turned her head, and there was Bob, grinning at her placidly. His
cap was gone and several buttons were ripped bodily from his mackinaw,
but he did not seem to be injured and when he pulled Betty to her feet,
that young person found that she, too, was unhurt.

"What happened?" she asked. "Where are we?"

"The bobsled balked," explained Bob cheerfully. "Guess it knew where we
were heading for better than I did. Anyway, you and I took a double
header that was a beauty. If you want to see where we came down, just
look up there."

Betty followed the direction of his finger and saw a trail gashed in the
snow, a trail that twisted and turned down the steep, forbidding sides
of a frowning gorge. Was it possible that they had fallen so far and
escaped injury?

"Know where you are?" asked Bob, watching her.

Betty shook her head.

"I must have been away off the road," explained Bob. "Betsey, you and I
are standing at the bottom of Indian Chasm."

CHAPTER XXV

THE TREASURE

Indian Chasm!

Betty stared at Bob in dismay. Afterward she confessed that her first
thought was of Indians who might capture them.

"Indian Chasm," repeated Bob firmly. "Come on, Betty, we mustn't stand
here. If you once get cold, there's no way to warm you up. We must walk,
and try to find a way out."

Betty stumbled after him, her mind a bewildered maze. She could not yet
grasp the explanation that Bob, turned about by their spill in the
hollow, had followed an old trail instead of the hill road. The trail had
led straight to the border of the chasm.

Bob ploughed along, head bent, a heavy sense of responsibility keeping
him silent. He knew better than Betty the difficulties that in all
probability lay before them.

He glanced back at Betty, wearily toiling after him.

"Want to rest a moment?" he suggested. "Sit on that rock till you begin
to feel chilly."

Betty accepted the suggestion gratefully. She was very tired and she was
hungry. Her rubbers had been torn on the stones she had encountered in
her fall and her shoes were damp.

"What a funny rock," she said idly.

It was a huge slab that had once been a part of another huge rock
which still stood upright. Some
