CHAPTER XIII

The Night Watchers

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.

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.

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.

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.

Now use of the grounds was restricted to affairs of long standing that

it would be inconvenient to change or to cancel.

That was a definite effect, he admitted to himself. But who could profit

by it?

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.

Only, why roam the fields?

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.

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.

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?

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.

Scotty spoke in a whisper. "What makes dogs bark at night?"

"Maybe a fox," Rick replied.

"Or a ghost?"

Rick sat bolt upright. "Maybe!"

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?"

Rick looked at the luminous dial of his watch. It was past midnight. "No

chases ending in quarries?"

Scotty's chuckle was low. "No chases. Listen a minute!"

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.

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.

"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.

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.

"Going spook hunting?"

"Yes, sir," Rick replied softly. "We're going to see why the dogs are

barking."

"No chases," the scientist warned. "If you should see anything, stay

away from it. Watch from a respectful distance."

"We will," Rick promised.

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.

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.

"Let's get to the tree belt," Scotty said in a whisper. "We can watch

both fields from there."

"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.

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.

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.

Scotty put his lips to Rick's ear. "Look around the tree, on top of the

mine in the upland cornfield. Be very careful."

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!

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!

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.

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.

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.

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.

"They must be heading for the field where the plane is parked," Rick

guessed. "We want to keep an eye on them."

"That we will," Scotty assured him. "Follow me, old son. We're making

real progress tonight!"

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.

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.

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."

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.

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?

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!

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.

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?"

"Jethro Collins?"

"Nope. It's Hilleboe. Dr. Miller's next-door neighbor!"
