<h3>Trapped!</h3>
<p>It was, as Rick said, time for action and not for words. He and Scotty
set out to track down every possible shred of evidence. They armed
themselves with flashlights, and Rick made sure he had his pocket lens,
and they started out.</p>
<p>The first stop was in the field, to locate the places where last night's
ghostly party had paused.</p>
<p>As the boys walked across the field toward the plane, Rick wondered
aloud. "What did the ghost want with the plane?"</p>
<p>"Sabotage?" Scotty asked.</p>
<p>"Maybe. But if so, why?"</p>
<p>"Because he was afraid of what we might see from the air, maybe."</p>
<p>Rick considered. "It could be, I suppose, but we've examined the whole
area from the plane. I didn't see anything suspicious or particularly
interesting."</p>
<p>"Not a thing," Scotty confirmed. "But it might be a good idea to take
another look."</p>
<p>"Okay. We can do it later this afternoon. Now, according to what I
remember, the first stop the ghosts made was right about here. Let's
work like hunting dogs and see what we can turn up."</p>
<p>Rick dropped his handkerchief on a clump of bachelor's-buttons for a
marker, then he and Scotty walked in ever-widening circles, scanning the
ground for any trace of the ghosts.</p>
<p>Scotty's keen eyes saw the first sign, a heelprint in a bare place in
the grass. The boys examined it. "Doesn't match anyone's shoes," Scotty
said. "Not of our gang. Leather heels, a little worn, run down on the
outside edge. You can see the nail marks. No rubber heels would make
those marks."</p>
<p>There were other prints, now that they were searching closely. Clearly,
three men had walked the field last night. But nowhere did they find a
clue to what the men had searched for. There was no raw dirt, no
impressions left where something had been removed.</p>
<p>"Fact," Rick stated. "Three men were here."</p>
<p>Scotty laughed. "This does not mean there were not also three ghosts who
left no tracks."</p>
<p>Rick had to laugh, too. "Now what do we do?"</p>
<p>"Look in the upland cornfield."</p>
<p>They started the survey of the cornfield directly above the mine
entrance, where they had first seen the three ghosts. Tracks were
visible almost at once.</p>
<p>"We're lucky," Scotty said. "Even with the weeds between the rows
there's enough bare ground so we can do some real tracking. Let's see
how the tracks run."</p>
<p>As Scotty had predicted, the tracking was much easier. A few yards into
the cornfield they came to a gap where a few seeds had failed to
germinate or the plants had died. It was a bare space, sparsely grown
with weeds.</p>
<p>Scotty pointed to the three sets of tracks, and put his own feet in one
set, while Rick did the same with another set. From the position of the
third set it was clear that the three men had faced each other.</p>
<p>Rick said excitedly, "They paused and bent over. But over what?"</p>
<p>They scrutinized the ground minutely. It seemed normal enough. There was
absolutely no sign that the earth had been disturbed.</p>
<p>Rick picked up a handful of soil and examined it. "Dirt," he said.
"Plain dirt. Why was it so interesting to the spooks?"</p>
<p>"Try your lens," Scotty reminded him.</p>
<p>Rick did so. The lens showed the usual combination of mineral and
organic matter of various sizes and colors. "I can't see anything
unusual," he reported. "Maybe the lens isn't powerful enough. I'll take
a sample and look at it under the microscope later." He found a scrap of
paper in his wallet and folded a bit of dirt into it.</p>
<p>"Let's continue," Scotty urged.</p>
<p>They worked their way across the cornfield, following the tracks. Twice
more they found places where the ghosts had paused to confer about
something, or examine something.</p>
<p>Then, at the edge of the cornfield, they lost the tracks in a rank
growth of weeds. Probably the ghosts had trampled the weeds last night,
but they had sprung up again and left no trace of the passage.</p>
<p>Scotty took the lead. "I'll show you where the car was parked."</p>
<p>They traveled through alternate weeds and hay to where the hilltop
dropped away rapidly to a valley about three hundred feet below. This
marked the end of the igneous outcropping in which the lead mine was
located, Rick guessed. The hill was steep, and overgrown with blackberry
bushes.</p>
<p>"I got caught a thousand times in as many feet last night," Scotty
commented. "It's easy by day, but don't try it by night." He led the way
through clear spaces between the thorny patches, always going downhill.</p>
<p>It wasn't long before Rick saw the road, if it could be called that. It
was two ruts with grass growing between them.</p>
<p>"Doesn't look like U.S. Highway Number 66," he remarked.</p>
<p>"There's a man who thinks it is," Scotty replied.</p>
<p>Rick looked to where his pal pointed. The Frostola man was approaching
on his scooter. The sound of the little motor was just audible, and
Rick's first impulse was to duck, but Scotty said, "Too late. He saw us
just as we saw him. Let's walk down to the road and make it casual."</p>
<p>They did so, and the peddler approached, bumping over the uneven
surface.</p>
<p>"Howdy," he greeted them. "Where does this road go?"</p>
<p>"We don't know," Scotty replied.</p>
<p>Rick added, "We're strangers in the area."</p>
<p>"I'm pretty new myself," the man said cheerfully. "Saw this road and
thought there might be a settlement where I could find some new
customers."</p>
<p>"We don't know of any," Rick said.</p>
<p>"Looks like I might as well go back to town, then. Want a lift? You can
hang onto the step behind me."</p>
<p>"No, thanks," Scotty replied. "We're staying just over the hill."</p>
<p>The Frostola man turned his scooter wagon, gave them a wave, and went on
his way back toward town. The boys watched until he drove out of sight.</p>
<p>"There's an optimist," Scotty said. "Follows a pair of ruts, hoping to
find civilization at the other end."</p>
<p>Rick grinned. "He certainly likes this part of Virginia. There's one
thing about peddling Frostola here—"</p>
<p>"What's that?"</p>
<p>"No customers to bother you. It's easy to commune with Nature."</p>
<p>"Aye-aye. Does he look like a nature lover to you?"</p>
<p>"Now that you mention it, I've seen people who fitted the part better.
We scared him away, that's for sure. But what was he doing here?"</p>
<p>Scotty considered. "If he wanted to reach the mine area without people
noticing him, he could park his scooter here and walk over the hill."</p>
<p>"He could," Rick agreed. "But why would he want to reach the mine area?"</p>
<p>"Not to sell Frostola. That's for sure."</p>
<p>"Uh-uh. My guess is he has to reset the Blue Ghost."</p>
<p>"Reset it?"</p>
<p>"Sure. Think about it. The projector can't go on operating forever when
a clock reaches nine, can it? It must need servicing and resetting."</p>
<p>"And loading with methyl chloride to squirt at us?"</p>
<p>"Too true." Rick had wondered about that. "But how does the chemical
squirter work? Where is it? The projector must be close to the Blue
Ghost, if the chemical came from the same place."</p>
<p>Scotty laughed. "You don't discourage easily, do you? We tried to find a
projector beam the other night, remember? What did we get for it? A
squirt in the face. No projector, no nothing."</p>
<p>"There has to be a projector, or an imagemaker of some kind," Rick
insisted, "unless you're admitting the ghost is real."</p>
<p>"Where would it be located?"</p>
<p>"Very close, I'd guess. Hidden somewhere near the spring pool, batteries
and all. It has to be, and I think we'd better spend some time looking."</p>
<p>"Starting where? Don't tell me—it has to be the mine."</p>
<p>Rick was already walking back up the hill toward the cornfield. "There's
no other underground location in which a projector could be stored, is
there? So let's get at it."</p>
<p>"Glad we brought flashlights," was Scotty's only comment.</p>
<p>They hiked in silence to the cornfield, pausing now and then among the
corn plants to examine footprints. Thanks to the rain that had left the
ground soft, there were plenty of them, but they told the boys no more
than they already knew.</p>
<p>At the top of the hill above the mine they paused to survey the scene.
Belsely was hauling a load of rock through the field near the plane,
using his tractor and a stoneboat. The boys knew he was busy building a
stone fence. He saw them and waved. They waved back, then went down the
hill to the spring and its basin.</p>
<p>Again they examined the entire location with great care, and Scotty
probed seams in the rock with his jackknife blade. The entire hillside
in this location was cracked and seamed and the rock face above the
basin was rough and irregular. Rick wondered if there had ever been an
earthquake in the neighborhood or whether the settling of the earth into
the mine has caused the cracking.</p>
<p>"Nothing here," Scotty said. "At least nothing I can see. We'll have to
try the mine itself."</p>
<p>They had replaced the boards at the entrance, simply pushing the nails
back into the holes from which they had come. They pulled the boards
aside and saw footprints—and not their own!</p>
<p>"Visitor," Scotty said with excitement.</p>
<p>Rick noted the size of the tracks. "And a big-footed one, too. Makes our
tracks look small."</p>
<p>Scotty pointed. "He came out again, whoever he was. Let's see how far he
went in."</p>
<p>The tracks told the story clearly and quickly. The visitor had gone in
about twenty feet, and had then returned to the outside. One glance told
the boys why.</p>
<p>The mine was timbered, with uprights and overhead beams spaced about
every ten feet. Where the visitor had stopped, the mine timbers were
supporting a big piece—or many pieces—of the rock overhead. Rick
guessed that the heavy rain, working through cracks, had loosened a
section and let its weight fall on the overhead crosspiece. It was also
clear that the timbers would not support the weight for very long. They
were rotten, and wet with the constant seepage of water.</p>
<p>"Must have been one of the Sons of the Old Dominion who wandered in for
a look," Rick suggested. "He saw it wasn't safe and went right out
again."</p>
<p>"Something like that," Scotty agreed. "And it isn't safe. Those timbers
would go if anyone breathed hard at them."</p>
<p>"Then let's not breathe hard," Rick said.</p>
<p>"Meaning that we're going in, anyway."</p>
<p>Rick pointed out, with what he thought was complete logic, that the
timbers had held the roof up since the rain, and that collapse surely
wouldn't take place in a minute or two. He concluded, "And if we're
going to find any kind of clue to a projector, it has to be in this mine
somewhere."</p>
<p>"Then let's not linger," Scotty said. "And for Pete's sake don't stamp
your feet when you go by the timbers. A little vibration would send them
down for sure."</p>
<p>Rick asked, "What were the wind and the laughter the last time we were
in here?"</p>
<p>"Imagination," Scotty replied. "Let's keep it under control this time."</p>
<p>"I'm with you. And ghosts don't blow out flashlights, so let's go."</p>
<p>They moved cautiously past the unsafe place, lights probing the tunnel
walls for a sign of anything unusual or worthy of attention. Now and
then they reached a bay where ore had been taken out, or a jog in the
tunnel where the miners had lost the ore vein temporarily. They reached
the spot of their penetration into the mine on their last visit and
found the remains of their torches.</p>
<p>"No change. Thought they might have been chewed by ghosts," Scotty
commented.</p>
<p>"Newsprint doesn't taste good," Rick replied. "Do ghosts have teeth?"</p>
<p>"Nope, just an icy breath. Do you remember any smell, by the way? When
we got hit in our faces?"</p>
<p>"Something sort of sweet?"</p>
<p>"Yes. I wasn't thinking about smelling, and I didn't notice especially,
but I sort of recall a nice odor."</p>
<p>Rick thought he remembered it, too. "We'll look up methyl chloride in
the dictionary," he promised. "That will tell us if it has an odor."</p>
<p>The mine took a sharp turn. "They lost the vein here and had to chew out
some rock to find it again," Rick pointed out. "Notice everything is on
one level? Must have been just one vein. It ran out and the mine closed
down."</p>
<p>"Looks that way," Scotty agreed. "How far have we come?"</p>
<p>Rick hadn't kept track, but he estimated they were perhaps halfway under
the hill. "This must end somewhere," he said. "Notice there isn't any
water at all, not even seepage? I'm still baffled by that spring and the
pipe."</p>
<p>They traversed another hundred yards in silence, flashlights constantly
scanning the mine. There was nothing out of the ordinary, no sign of
ghost, projector, or even of human visitation for dozens of years.</p>
<p>"We're on another wild-goose..." Rick began. He never finished, for
sound suddenly reverberated through the mine, the sound of rock crashing
downward.</p>
<p>Both boys turned and ran back toward the entrance, afraid of what they
would find. Long before they reached it, billowing clouds of dust told
them what had happened.</p>
<p>Their racing legs confirmed it as they came to a stop against rock that
choked the tunnel from top to bottom.</p>
