<h3>The Night Watchers</h3>
<p>Rick couldn't sleep. He kept trying for a comfortable position, but the
hitherto excellent bed suddenly seemed full of lumps. His pillow
wouldn't behave, either. It seemed determined to lump up and deprive him
of sleep.</p>
<p>His body was tired enough, but his mind kept worrying the problem of the
Blue Ghost endlessly, going over incidents and details, searching for a
meaning, a clue that would lead to a conclusion.</p>
<p>What was the reason for the Blue Ghost? If he could only figure that
much out the rest would follow naturally. If the assumption that the
ghost was man-made was correct, there had to be some reason for the
apparition.</p>
<p>So far as he knew, the ghost had had only one effect, and that was to
reduce drastically the use of the picnic ground in front of the old
mine. According to the Millers, the grounds were in constant use most
years, with family parties, group affairs, and young people spending
considerable time in swimming, eating, ball games, and all the other
amusements of people who sought the coolness of trees and water to
escape the Virginia summer heat.</p>
<p>Now use of the grounds was restricted to affairs of long standing that
it would be inconvenient to change or to cancel.</p>
<p>That was a definite effect, he admitted to himself. But who could profit
by it?</p>
<p>There was only one possible clue, and that lay in the midnight prowlings
of the Blue Ghost and his varying number of companions. Turning the
picnic area into a forbidding place, a haunted ground, would give the
ghost and friends ample opportunity to roam the upper and lower fields
without interference.</p>
<p>Only, why roam the fields?</p>
<p>Somehow, the radioactive dust in the cement bags must tie into it, but
Rick couldn't imagine the connection. He thought of a secret uranium
strike and rejected it. Empty bags pointed to something gotten rid of,
not something gained by a discovery.</p>
<p>The thought was intriguing. If he assumed the bags had arrived full,
what had happened to the contents? He tried to think of uses for the
powdered ore and couldn't. Even if he could imagine a secret processing
plant to extract the uranium for some purpose, there wasn't enough. A
sufficient quantity of ore to provide even a gram of uranium metal would
mean literally thousands of bags and they had found less than a dozen.</p>
<p>Of course there was the cart Belsely had seen. Rick couldn't credit the
farmer's notion that the ghost soldiers had been collecting ghost bodies
of the long-dead. But what had the cart been doing? The very idea of a
cart led to the idea of something too heavy to be carried without
mechanical aid. What? Bags of radioactive ore dust?</p>
<p>He was still tossing in his bed and chewing the data fine when the dogs
began to bark. He listened. The barking was far away, probably a mile or
more. There were farms on the road to town, and probably all of them had
dogs.</p>
<p>Scotty spoke in a whisper. "What makes dogs bark at night?"</p>
<p>"Maybe a fox," Rick replied.</p>
<p>"Or a ghost?"</p>
<p>Rick sat bolt upright. "Maybe!"</p>
<p>Scotty swung to a sitting position on the side of his bed. "I've been
listening to you twisting and turning for an hour. If you're going to
keep me awake, it might as well be useful. What say we go look?"</p>
<p>Rick looked at the luminous dial of his watch. It was past midnight. "No
chases ending in quarries?"</p>
<p>Scotty's chuckle was low. "No chases. Listen a minute!"</p>
<p>Rick held his breath, and heard what Scotty's keen ears had detected.
There was the sound of a car somewhere far away. He couldn't tell the
direction, but he was sure it was not the road from town because the
bedroom windows opened on the town side of the farmhouse.</p>
<p>The night was clear and still, and sounds would carry great distances.
The car might even be on the main highway, about five miles away.</p>
<p>"Let's get going," Rick said softly. He fumbled for his clothes on the
chair at the foot of his bed and dressed quietly. Scotty was doing the
same on his own side of the room.</p>
<p>They checked flashlights, then started down the stairs. The treads
creaked noisily, as is the case in old houses, and Dr. Miller's voice
stopped them.</p>
<p>"Going spook hunting?"</p>
<p>"Yes, sir," Rick replied softly. "We're going to see why the dogs are
barking."</p>
<p>"No chases," the scientist warned. "If you should see anything, stay
away from it. Watch from a respectful distance."</p>
<p>"We will," Rick promised.</p>
<p>Outside, the night was lighted only by stars and a crescent moon. Trees
were dark shapes against the lighter darkness of the night as the boys
made their way through the orchard. They headed for the plane, intending
to stop at the edge of the orchard to reconnoiter.</p>
<p>The field before them stretched dark and empty to the trees along the
creek, except for the angular bulk of the plane. Rick watched and
listened with every sense alert. Insects hummed now and then, but that
was all.</p>
<p>"Let's get to the tree belt," Scotty said in a whisper. "We can watch
both fields from there."</p>
<p>"Okay." Rick led the way at a half trot that covered ground rapidly. In
a few minutes they were across the creek and among the trees. They
slowed their pace, stopping now and then to listen. The dogs were still
barking, but the noise came from far away, on the other side of the hill
in which the mine was located.</p>
<p>Scotty took the lead as they approached the picnic grounds. He was
noiseless as a shadow, and Rick tried hard to step exactly in his
footprints to avoid any noise.</p>
<p>Using the great oaks for cover, Scotty moved to the picnic grounds,
among the tables and stone cooking pits. Suddenly he took Rick's arm and
squeezed. Rick stopped instantly, ready for whatever action was
indicated.</p>
<p>Scotty put his lips to Rick's ear. "Look around the tree, on top of the
mine in the upland cornfield. Be very careful."</p>
<p>Rick moved into position, then with extreme caution he peered around the
protecting tree. The first thing he saw on the hill was the Blue Ghost,
not in his apparition form, but as the human-headed light they had
chased. Then he realized that he was also seeing a form under the light,
a human shape silhouetted faintly against the dark sky!</p>
<p>He choked back an exclamation. There were two other shapes, unlighted,
but clearly human. This was what the tenant farmer had seen! But what
were they doing in the cornfield? In a moment it became clear. The three
were coming his way!</p>
<p>Scotty squeezed his shoulder and pointed up. Rick realized suddenly that
they were hiding behind the oak in which they had watched unsuccessfully
for the Blue Ghost. He jumped for the lowest branch and quickly hauled
himself into the protecting foliage. Scotty was close behind him.</p>
<p>Through openings in the foliage they saw the Blue Ghost make his way
down the hillside with his two companions, saw the three pause at the
basin in which the ghost made his public appearances. Rick shuddered as
he heard soft, ghostly laughter. He was convinced that he watched three
men, but the memory of the bitter, burning cold on his face was still
too fresh and green not to feel a reaction.</p>
<p>The ghostly trio continued down the slope to the picnic grounds and
turned to the road that led to the bridge. Rick would have given much
for enough moonlight to see details, but he could see only the three
vague shapes. He thought the figure with the softly lighted apparatus on
his head carried something in one hand, but he wasn't sure.</p>
<p>Not until the trio passed out of sight behind the trees did the boys
descend from the tree, then they paused for a whispered consultation
that couldn't have been heard three feet away.</p>
<p>"They must be heading for the field where the plane is parked," Rick
guessed. "We want to keep an eye on them."</p>
<p>"That we will," Scotty assured him. "Follow me, old son. We're making
real progress tonight!"</p>
<p>Scotty led the way through the tree belt to the bank of the creek. He
paused in the trees long enough to be sure the ghost trio had crossed
the creek, then picked positions behind the earthworks erected by
Confederate soldiers long ago.</p>
<p>Rick watched the ghosts—for he thought of them by that useful term even
though he now knew they were mortal—as they walked slowly across the
field. He saw them pause, and saw the dark figures shorten as they bent
over. He took a bearing on the spot, using the dim shape of his plane
for one reference and the bridge for another. He thought he could locate
the position again by daylight.</p>
<p>In a moment the three moved on again, while Rick watched, puzzled. He
felt Scotty move and put his head close to hear what his pal had to say.
"They had to come from somewhere, and I suspect it was by car. They
didn't come up the road to town, so they must have used the road in the
valley on the other side of the hill. I'm going to take a look. If
there's a car there, I can at least get a license number. You watch 'em.
If I'm not back by the time they cross to this side, don't worry. I
won't get caught. Just go on home and wait for me."</p>
<p>Rick whispered an okay, and Scotty melted into the night with the
noiseless skill that Rick so much admired. Then he turned his attention
to the ghosts once more.</p>
<p>Rick counted five stops in various parts of the field. After the last
one, the trio turned, recrossed the bridge, moving briskly, climbed the
hill, and disappeared into the cornfield. Mission accomplished,
apparently. What had the mission been?</p>
<p>According to Belsely, this happened each time, except for the occasion
when a cart had been used. What were they hunting? Or, if they weren't
hunting, what were they doing? Rick felt frustrated. To be so close, yet
to be unable to see anything but vague shapes in the darkness!</p>
<p>Tomorrow he and Scotty would search both fields in an effort to find
what the Blue Ghost sought, or to try to figure out what he and his
friends were doing.</p>
<p>Scotty caught up with him as he was crossing the field by his plane. The
dark-haired boy was triumphant. "They had a car, all right, and the
registration was in a container on the steering wheel. I've got all the
dope. Probably I shouldn't have done it, but I sneaked a quick look at
the name. Can you imagine what it is?"</p>
<p>"Jethro Collins?"</p>
<p>"Nope. It's Hilleboe. Dr. Miller's next-door neighbor!"</p>
