it come
from there?"
"Does it matter? Val, do you suppose they could hear me if I pounded on
the wall at this side?"
"You haven't anything heavy enough to pound with."
"Yes, I have. This package thing that you found. It's quite heavy. Val,
we've got to let them know we're here!"
She crawled away, moving with caution lest she bring on another slide.
That reassuring _thud, thud_ still sounded. Then, after long minutes,
Val heard the answering blow from their side. Three times Ricky struck
before the rhythm of the digging was broken. Then there was silence
followed by three sharp blows. They had heard!
Ricky beat a perfect tattoo in joy and was quickly answered. Then the
_thud, thud_ began again, but this time the pace was quickened.
"They've heard! They're coming!" Ricky's voice shrilled until it became
a scream. "Val, we're found!"
A clod was loosened somewhere above them and crashed upon the wreckage.
Would the efforts of their rescuers bring on another slide?
"Be quiet, Ricky," Val croaked a warning, "it's still moving."
Then there came the sharp clink of metal against stone. "Val," called
Ricky, "they're right against the wall now!"
"Come back here, away from it. We--we don't want you caught, too," he

the rescuers or the second slide?
There was a vicious grinding noise from the walled end of the passage. A
moment later a blinding ray of light swung in, to focus upon them.
"Ricky! Val!"
Val was blinking stupidly at the light, but Ricky had presence of mind
enough to answer.
"Here we are!"
"Look out," Val roused enough to warn, "the walls are unsafe!"
"We're coming through," rang the answer out of the dark. "Stand away!"
Now that they could see, Val realized for the first time the danger of
their position. A jagged, water-rotted beam half covered with clay and
sand lay across him, and beyond that was a mass of splintered wood and
wet earth. A little sick, he looked up at Ricky. She was staring at the
wreckage. Her eyes were black in a white, mud-smeared face.
"Val--Val!" His name came as the thinnest of whispers.
"It isn't as bad as it looks," he said hurriedly. "Something underneath
