The waiter gave him a long glance. "And your drink, sir?"

"Water," said Jerry. "Cool, refreshing water, preferably with a small

piece of ice."

The waiter favored the trio with another unflattering look and went to

the kitchen.

"This is a gyp place," Penny declared indignantly. "I can't understand

why anyone would come here. The waiters all seem to be French."

"Oh, all head waiters speak French," Jerry replied. "You can't tell by

that. I'd say they were German myself."

Penny studied the cafe employees with new interest. She noted that the

head waiter kept an alert eye upon the entire room, but particularly he

watched their table.

Soon the three orders of ham sandwiches were brought by the waiter. The

young people ate as slowly as they could so they would have an excuse for

remaining as long as they desired.

"What time is it, Jerry?" Penny asked anxiously.

"Ten after nine," he answered, looking at his watch.

A bell jingled, and the young people knew that another customer had

arrived. Craning their necks to see around the palm tree, they watched

the dining room entranceway. In a moment a young man entered and was

greeted by the head waiter. Jerry and the girls stared, scarcely

believing their eyes.

"Why, it's Burt Ottman!" Penny whispered.

"And exactly on the dot of nine-fifteen," added Louise significantly. "He

_must_ be the person who lost that billfold!"

CHAPTER

12

_JERRY'S DISAPPEARANCE_

Without noticing Jerry and the girls, Burt Ottman walked directly to a

table at the other side of the dining room. He spoke to the stranger whom

Penny and Louise had followed, and sat down opposite him.

"Ha! The plot thickens!" commented Jerry in an undertone. "Obviously our

friend and Burt Ottman had an appointment together."

"This is certainly a shock to me," declared Penny. "I'd made up my mind

that Burt had nothing whatsoever to do with the dynamiting. Now I don't

know what to think."

"He must be the saboteur," Louise said, speaking louder than she

realized. "We picked up the billfold along the river and it undoubtedly

was his."

"He denied it," replied Penny. "However, when I spoke of The Green Parrot

I noticed that he seemed to recognize the name. Oh, dear!"

"Now don't take it so hard," Jerry comforted her. "The best thing to do

is to report what we've seen to police and let them draw their own

conclusions."

"I suppose so," Penny admitted gloomily. "I had hoped to help Sara and

her brother."

"You wouldn't want to protect a saboteur?"

"Of course not, Jerry. Oh, dear, it's all so mixed up."

So intent had the young people been upon their conversation that they

failed to observe a waiter hovering near. Nor did it occur to them that

he might be listening. As Jerry chanced to glance toward him, he bowed,

and moving forward, presented the bill.

"Howling cats!" the reporter muttered after the waiter had discreetly

withdrawn. "Will you look at this!"

"How much is it?" Penny asked anxiously. "We only had three ham

sandwiches."

"Two dollars cover charge. Three sandwiches, one dollar and a half. Tip,

fifty cents. Grand total, four dollars, plus sales tax."

"Why, that's robbery!" Penny exclaimed. "I wouldn't pay it, Jerry."

"I can't," he admitted, slightly abashed. "I only have three dollars in

my pocket. Then I'll have to buy my hat back from the checkroom girl."

"Louise and I haven't any money either," Penny said. "Thirty-eight cents

to be exact."

"Thirty-three," corrected her chum.

"Tell you what," said Jerry after a moment of thought. "You girls stay

here and hold down the chairs. I'll go outside and telephone one of the

boys at the office. I'll have someone bring me some cash."

Left to themselves, the girls tried to act as if nothing were wrong.

However, they were very conscious of the waiter's scrutiny. Every time

the man entered the dining room with a tray of food, he gazed

suggestively at the unpaid bill.

"I'd feel more comfortable under the table," Penny commented. "Why

doesn't Jerry hurry?"

"Perhaps he can't find a telephone."

"Something is keeping him. We're going to become conspicuous if we stay

here much longer."

The girls fumbled with their purses and sipped at their water glasses

until the tumblers were empty. Minutes passed and still Jerry did not

return.

After a while, Burt Ottman's companion left the dining room. The young

owner of the boat dock waited until the older man had vanished, and then

called for his check. If the bill were unusually large he did not appear

to notice, for he paid it without protest and likewise left the dining

room.

"Louise, I don't want to stay here any longer," Penny said nervously. "I

can't understand what's keeping Jerry."

"Why not go out to the foyer and look for him."

"A good idea if we can get away with it," Penny approved. "I judge

though, that if we start off, the waiter will pursue us with the bill."

"Couldn't we just explain?"

"We can try. Anyway, it will be interesting to see what will happen."

Before leaving the table, Penny scribbled a hasty note which she left for

Jerry on his plate. It merely said that the girls would wait for him in

the foyer. Choosing a moment when their own waiter was occupied at

another table, they sauntered across the room and out into the hall.

"That wasn't half as hard as I thought it would be," chuckled Penny. "But

where's Jerry?"

The foyer was deserted. Noticing a stairway which led to a lower level,

the girls decided that the telephones must be located below. They started

down, but soon realized their mistake for no light was burning in the

lower hall.

"We're not supposed to be down here," Louise murmured, holding back.

"Wait!" whispered Penny.

At the far end of the dingy hall she had glimpsed a moving figure. For

just a second she thought that the young man might be Jerry. Then she saw

that it was Burt Ottman.

"What do you suppose he's doing down here?" she speculated. "He seems to

be familiar with all the nooks and crannies of this place."

Burt Ottman had not seen or heard the girls. They saw him pause at the

end of the hall and knock four times on a closed door. A circular

peep-hole shot open and a voice muttered: "Who is it?"

The girls heard no more. Someone touched Penny on the shoulder from

behind. With a startled exclamation, she whirled around to face the head

waiter.

"So sorry, Mademoiselle, to have frightened you," he said blandly. "You

have taken the wrong stairway."

"Why, yes," stammered Penny, trying to collect her wits. "We were looking

for the public telephones."

"This way please. You will find them in the foyer. Just follow me."

Penny and Louise had no choice but to obey. They wondered if the head

waiter knew how much they had seen. His expressionless face gave them no

clue.

"We were waiting for our friend," Louise remarked to cover her

embarrassment.

"The young man who escorted you here?"

"Yes," nodded Louise. "He went to telephone and we haven't seen him

since."

The waiter had reached the top of the stairs. He turned and looked

directly at the girls as he said: "The young man left here some minutes

ago."

"He left!" Penny exclaimed incredulously. "But the bill wasn't paid."

"Oh, yes, the young gentleman took care of it."

"Why, Jerry didn't have enough money," Penny protested, unable to grasp

the situation. "You're sure he left the cafe?"

"Yes, Mademoiselle."

"And didn't he leave any message for us?"

"I regret that he did not," the waiter replied. "As young ladies without

escorts are not permitted at The Green Parrot, I suggest that you leave

at once."

"You may be sure we will," said Penny. "I simply can't understand why

Jerry would go off without saying a word to us."

The head waiter conducted the girls to the exit, bowing as he closed the

door in their faces. Rather bewildered, they huddled together on the

stone steps. Rain had started to fall once more and the air was

unpleasantly cold.

"We certainly got out of that place in a hurry," Louise commented. "If

you ask me, it was a shabby trick for Jerry to go off and leave us.

Especially when he knew we didn't have the price of a taxi."

"Lou," said Penny soberly, "I don't believe that Jerry did desert us."

"But he disappeared! And the head waiter told us that he left."

"Something happened to Jerry when he went to telephone--that's certain,"

replied Penny, thinking aloud.

"Then you believe he was forcibly ejected?"

"No one could have tossed Jerry out of The Green Parrot without a little

opposition."

"Jerry's quite a scrapper when he's aroused," Louise agreed. "We didn't

hear any sound of scuffling. What do you think became of him?"

"I don't know and I'm worried," confessed Penny. Taking Louise's arm, she

guided her up the stone steps to the street. "The thing for us to do is

to get home and tell Dad everything! Jerry may be in serious trouble."

CHAPTER

13

_A VACANT BUILDING_

Hastening to a main street, Penny and Louise waited many minutes for a

bus. Finally as a taxi cruised past they hailed it, knowing they could

obtain cab fare when they reached home.

"Let's go straight to my house," Penny said, giving the driver her

address. "Dad should be there by this time. I know he'll be as worried

about Jerry as we are."

A few minutes later the taxi drew up in front of the Parker home. Lights

burned in the living room and the girls were greatly relieved to glimpse

the editor reading in a comfortable chair by the fireplace.

"Dad, I need a dollar sixty for cab fare!" Penny announced, bursting in

upon him.

"A dollar sixty," he protested, reaching for his wallet. "I thought you

and Louise went to a picture show. What have you been doing in a

taxicab?"

"I'll explain just as soon as I pay the driver. Please, this is an

emergency."

Mr. Parker gave her two dollars and she ran outside with it. In a moment

she came back with Louise.

"Now, Penny, suppose you explain," suggested Mr. Parker. "Has walking

become an outmoded sport or are you trying to save wear and tear on rayon

stockings?"

"Dad, Louise and I never went to the Rialto Theatre," Penny said

breathlessly. "We've been at The Green Parrot!"

"_The Green Parrot!_"

"Oh, we didn't go alone," Penny explained hastily as she saw disapproval

written on her father's face. "We telephoned Jerry and had him accompany

us."

"How did you learn the location of the place?"

"We heard a man give the address to a taxi driver, and followed in

another cab. Dad, we saw Burt Ottman there!"

"Interesting, but it hardly proves that he is a saboteur."

"He arrived at exactly nine-fifteen," Penny resumed excitedly. "After

talking with that man we followed, they both left the dining room, though

not together. We saw Burt go downstairs and knock on a door which had a

peephole."

"Did he enter?"

"I don't know," Penny admitted. "Louise and I weren't able to see. Just

as things were getting interesting the head waiter came and politely

escorted us out of the building."

"Why didn't Jerry bring you home?"

"That's what I'm getting at, Dad. Jerry just disappeared."

"What do you mean, Penny?"

Together the girls told him exactly what had happened at The Green

Parrot. Mr. Parker promptly agreed that it would not be like Jerry to

leave the cafe without an explanation.

"Something has happened to him!" Penny insisted soberly. "Dad, why don't

you call the police right away? It wouldn't surprise me one bit if The

Green Parrot is a meeting place for saboteurs! There's no telling what

they may have done to Jerry!"

By this time Mr. Parker had begun to share the alarm of the girls.

Getting abruptly to his feet, he started toward the telephone. Before he

could take down the receiver, the bell jingled. Answering the incoming

call, a peculiar expression came over the newspaper owner's face. After

talking for a moment, he hung up the receiver and turned toward Penny.

"That was Jerry," he announced dryly.

"Jerry!" Penny became confused. "But I don't understand, Dad. Is he being

held at The Green Parrot?"

"Jerry is at home. He called to ask if you and Louise arrived safely."

"Well, of all the nerve!" Penny cried indignantly. "Just wait until I see

him again!"

"Not so fast," advised her father. "There seems to have been a little

mix-up. After Jerry left the dining room to telephone, the head waiter

told him that you girls had decided not to wait."

"And he told us that Jerry had gone!" Louise cried. "I wonder why?"

"Because he wanted to get rid of our entire party!" Penny declared. "All

the time we were in the cafe that head waiter seemed to keep his eye on

us. Dad, what did Jerry do about paying the bill?"

"He was told that he need not settle it--that he could pay later."

"Well, it's all very peculiar," Penny said with a sigh. "I'm glad Jerry

is safe, but I still maintain we were hustled out of that place."

"No doubt you were," agreed her father. "I'm curious to see the

cafe--especially that door with the peep hole."

"I'll take you there," Penny offered eagerly.

"Not tonight," Mr. Parker declined, yawning. "Tomorrow morning perhaps."

Penny had to be satisfied with the decision, though she yearned for

immediate action. After Louise had gone to her own home, she mulled over

the situation, discussing every angle of it with her father.

"Why do you think Burt Ottman was at the Parrot?" she tried to pin him

down. "Would you say he's one of the plotters?"

"I have no opinion whatsoever," Mr. Parker responded somewhat wearily.

Penny did not allow her father to forget his promise to visit The Green

Parrot. The following morning she awoke early and at the breakfast table

reminded him that they had an important appointment together.

"I should be at the office," Mr. Parker said, glancing at his watch.

"Besides, the cafe won't be open at this hour."

"The manager should be there, Dad. You'll be able to talk to him and

really look over the place."

"We can ask a few questions--that's all," Mr. Parker corrected. "One

can't walk into an establishment and start searching."

"Let's go anyway," pleaded Penny.

More to please her than because he hoped to uncover vital evidence, Mr.

Parker agreed to make the trip. With Penny at the wheel of the family

car, they drove to the street where The Green Parrot was situated.

Parking not far from the entrance to an alley, they walked the remaining

distance.

"This is the place," said Penny, pausing before the familiar building.

"Why, what's become of the cafe?"

Bewildered, she stared at the doorway where the painted parrot sign had

swung. It was no longer there and the Venetian blinds had been removed

from the window.

"This place doesn't have the appearance of a cafe," said Mr. Parker. "Are

you sure you have the correct address, Penny?"

"Why, yes, I know we came here last night. But the sign has been

removed."

Descending the stone steps, Penny pressed her face against the uncovered

windows. Only a large, empty room confronted her astonished gaze. All of

the tables and chairs had been removed, even the palm trees and

decorations.

"It's deserted, Dad!" she exclaimed.

Mr. Parker came down the steps to peer through a window. Bits of colored

paper and menu cards still littered the floor. Testing the door, he found

it locked.

"This certainly is strange," he remarked thoughtfully. "Let's inquire

next door."

Penny and her father chose to enter a bakery which adjoined the building.

A stout woman in a white apron, who was arranging frosted cakes in a

showcase, favored them with a professional smile.

"Good morning," Mr. Parker greeted her, removing his hat. "Can you tell

me what has become of the cafe next door?"

"Are you from the police?" the woman asked quickly.

"No, I'm connected with the _Star_."

"Oh, a reporter!" assumed the woman, and Mr. Parker did not correct her.

"I thought maybe you were from the police. Yesterday I saw a man watching

The Green Parrot and I said to my husband, Gus, 'The cops are going to

raid that place.'"

"And did they?" interposed Mr. Parker.

"Not that I know of. The outfit just moved out. And a queer time to be

doing it too, if you ask me!"

"When did they leave?"

"The van pulled up there about two o'clock last night. They were loading

stuff in until almost dawn."

"Can you tell me where they went or why they moved out?"

"No, I can't," the woman replied with a shrug. "Like as not they were

afraid the police were going to raid 'em. I'm telling you that place

deserved to be closed up."

"Just what went on there?"

"I never was inside the place, but some mighty queer acting people seemed

to be running it. Why, I've seen men go in and out of there at four

o'clock of a morning, hours after the cafe closed up."

"Foreigners?"

"I couldn't rightly say as to that. My husband, Gus, thinks a lot of

gambling went on. Anyway, I'm glad the outfit's gone."

Unable to learn more, Penny and her father left the bakery and walked

toward their parked car. The information they had gained was not likely

to prove very helpful. Obviously, The Green Parrot had closed its doors,

fearing an investigation. Whether it had moved elsewhere or gone out of

existence, they could not know.

"The call that Jerry, Louise and I paid there last night may have had

something to do with it," Penny remarked. "I know the head waiter was

eager to be rid of us."

As Mr. Parker and his daughter walked slowly along, several persons ran

past them toward an alley. Approaching its entranceway, they saw that a

throng of people had gathered not far from the rear exit of The Green

Parrot.

"Wonder what's wrong back there?" speculated Mr. Parker, pausing.

"Probably an accident of some sort."

"Let's find out," proposed Penny.

She and her father joined the group of excited men and women in the

alley. They were startled to see a young man sprawled face downward on

the brick pavement. A garbage collector jabbered excitedly that he had

found the victim lying thus only a moment before.

Mr. Parker pushed through the circle of people. "Has anyone called an

ambulance?" he asked.

"I'll send for one, Mister," offered a boy, hastening away.

Mr. Parker bent over the prone figure.

"He ain't dead is he?" the garbage man asked anxiously.

"Unconscious," replied the newspaper man, his fingers on the victim's

wrist. "A nasty head wound. I'd say he either fell or was struck from

behind."

Carefully Mr. Parker rolled over the limp figure. As he beheld the face,

he stared and glanced quickly at Penny.

"Who is he, Dad?" she asked, and then she saw for herself.

The young man was Burt Ottman.

CHAPTER

14

_TEST BLACKOUT_

As Mr. Parker covered Burt Ottman with his overcoat, the young man

stirred and opened his eyes. He gazed at the newspaper owner with a dazed

expression and for a moment did not attempt to speak.

"Take it easy," Mr. Parker advised.

"What happened to me?" the young man whispered.

"That's what we'd like to know. Were you struck?"

"Don't remember," Ottman mumbled. He closed his eyes again, but aroused

as he heard the shrill siren of an approaching ambulance. "Don't let 'em

take me to a hospital," he pleaded. "Take me home."

The ambulance drew up in the alley. Stretcher bearers carefully lifted

the young man.

"I'm all right," he insisted, trying to sit up. "Just take me home."

"Where's that?" asked one of the attendants.

Burt Ottman mumbled an address which was on a street not far from the

boat dock he operated.

"We'll take you to the hospital for a check up," the young man was told.

"Then if you're okay, you'll be released."

Deeply interested in the case, Mr. Parker and Penny followed the

ambulance to City Hospital. There, after an hour's wait in the lobby they

were told that Burt Ottman had suffered no severe injury. A minor head

wound had been dressed, and he was to be released within a short while.

"What caused the accident?" Mr. Parker asked one of the nurses. "Did the

young man say?"

"He couldn't seem to remember what happened," she replied. "At least he

wouldn't talk to the doctor about it."

Overdue at the _Star_ office, Mr. Parker could remain no longer. However,

Penny, whose time was her own, loitered about the lobby for an hour and a

half until Burt Ottman came down in the elevator. The young man's head

was bandaged and he walked with an unsteady step as he leaned on the arm

of a nurse.

"I'll call a taxi for you," the young woman said. "You're really in no

condition to walk far, Mr. Ottman."

Penny stepped forward to offer her services. Her father, knowing that she

might have use for the car, had left it parked outside the hospital.

"I'll be glad to take Mr. Ottman home," she volunteered.

The young man protested that he did not wish to cause anyone

inconvenience, but allowed himself to be guided to the waiting

automobile.

As the car sped along toward the riverfront, Penny stole quick glances at

Burt. He sat very still, his gaze on the pavement ahead. She half

expected that he would offer an explanation of the accident, or at least

ask a few questions, but he remained silent.

"You took rather a hard blow on the head," she remarked, seeking to lead

him into conversation.

Burt merely nodded.

"Dad and I were astonished to find you lying in the alley at the rear of

The Green Parrot," Penny went on. "Don't you remember how you came to be

there?"

"Mind's a blank."

"You must have been struck by someone," Penny said, refusing to be

discouraged. "Can't you recall whom you were with just before the

accident?"

"What is this, a third degree?" Burt asked, and only a faint, amused

smile took the edge from his question.

"I'm sorry," Penny apologized.

"It doesn't matter what happened to me," Burt said quietly. "I just don't

feel like talking about it--see?"

"Yes."

"I don't mean to seem unappreciative," the young man resumed. "Thanks for

taking me home."

"You're very welcome, I'm sure," Penny responded dryly.

The car drew up in front of the home where Burt and his sister lived. A

pleasant, one-story cottage rather in need of paint, it was situated high

on a bluff overlooking the river.

As Burt stiffly alighted from the car, the cottage door opened, and Sara

came running to meet him.

"You're hurt!" she cried anxiously. "Oh, Burt, what happened to you?"

"Nothing," he answered, moving away from her encircling arms.

"But your head!"

"Your brother was hurt sometime last night," Penny explained to Sara.

"Just how, we don't know. My father and I found him lying in an alley at

the rear of The Green Parrot."

"The Green Parrot--that night club!" Sara gazed at her brother in dismay.

"Oh, Burt, I was afraid something like this would happen. Those dreadful

men--"

"Now Sara," he interrupted brusquely. "No theatricals, please.

Everything's all right." Giving her cheek a playful pinch, he wobbled

past her into the cottage.

Sara turned frightened eyes upon Penny. "Tell me exactly what happened,"

she pleaded.

"I honestly don't know, Sara. My father thought someone must have struck

your brother from behind, but he's not told us a thing."

"I just knew something of the sort would happen," Sara repeated

nervously.

"What do you mean?" inquired Penny. "Does your brother have enemies who

would harm him?"

"Burt's been trying to find out who framed him in the bridge dynamiting.

He won't tell me much about it, but I know he's been trailing down a few

leads."

"Isn't that work for the police?"

"The police!" Sara retorted bitterly. "Their only interest is in piling

up more evidence against Burt!"

"Your brother knows the identity of the saboteur?"

"He won't tell me, but I think he does have an idea who blew up the

bridge."

Penny scarcely knew whether or not to accept Sara's explanation of her

brother's activities. Unquestionably, the girl believed that he was

innocent of all charges against him. For one not prejudiced in his favor,

there were many factors to be considered. Why had Burt denied losing the

leather billfold? And with whom had he kept the Tuesday night appointment

at The Green Parrot?

"If your brother has any clue regarding the real saboteur, he should

present his evidence to the police," Penny advised Sara.

"He'll never do that until he's ready to appear in court. Not after the

way the police treated him."

Penny realized that nothing was to be gained by discussing the matter

further with Sara. Offering a few polite remarks to the effect that she

hoped Burt would soon recover completely from his injury, she drove away.

Later, in repeating the conversation to her father, she declared that she

could not make up her mind regarding Burt Ottman's guilt.

"The case does have interesting angles," Mr. Parker acknowledged. "I

talked to the Police Commissioner this morning about The Green Parrot.

The place long has had a reputation for cheating customers, and lately

it's been under suspicion as a rendezvous for anti-American groups."

"That would fit in with what the bakery woman told us. What became of The

Green Parrot, Dad? Have the police been able to trace it to a new

location?"

"Not yet. The cafe may not open up again, or if it does, under a new

name."

For two days Penny divided her time between school and the river. As the

water remained too rough for safe sailing, she and Louise spent their

spare hours painting and cleaning their boat. Upon several occasions they

called at the Ottman Boat Dock. Burt never was there, but Sara assured

them that her brother had completely recovered from his recent mishap.

"Did he never tell you how he was struck?" Penny inquired once.

"Never," Sara returned. "I've given up talking to him about it."

With the river high, the girls had no opportunity to visit Old Noah at

his ark. However, Sara told them that she was quite certain Sheriff

Anderson had not succeeded in getting rid of the old fellow and his

animals.

"The ark is still anchored up Bug Run," she laughed ruefully. "I know

because a steady flow of blue bottles has been floating down here!"

"Do you always read the message?" Louise inquired.

"Not always," Sara replied. "Frequently I do because they're so crazy."

Since his arrest and subsequent release from jail, Burt Ottman had seldom

been seen at the boat dock. Harassed and overburdened, Sara endeavored to

do the work of two people. She ran the motor launch, taking passengers up

and down the river. She rented canoes and row boats, and looked after

repair work which came to the shop. If she felt that her brother was

shirking his duties, she gave no inkling of it to the girls.

"When does Burt's trial come up?" Louise remarked to Penny late Thursday

night as they walked home from the Public Library. "Next week, isn't it?"

"Yes, the twenty-first," her chum nodded. "From all I can gather, he'll

be convicted, too."

"I feel sorry for Sara."

"So do I," agreed Penny. "At first I didn't like her very well. Now I

know her brusque manner doesn't mean anything."

The girls were passing a drugstore. In the window appeared a colored

advertisement, a picture of a giant chocolate soda, topped with frothy

whipped cream. Penny paused to gaze longingly at it.

"That's a personal invitation addressed to me," she remarked. "How about

it, Lou?"

"Oh, that same picture has been in the window for months," her chum said

discouragingly. "You can't get whipped cream unless you steal it from a

cow."

"Well, how about a dish of ice cream then? I'm horribly hungry."

"That's your natural state," teased Louise, pulling her on. "If we stop

now, we'll be caught in the test blackout."

"Is there one tonight?"

"Don't you read the papers? It's to be held between nine and ten o'clock.

And it's ten after nine now."

"I think it might be fun to be caught out in one--just so long as it's

not the real thing."

"I want to get home before the street lights are turned out," Louise

insisted. "In fact, I promised Mother I'd come straight home when the

library closed."

"Oh, all right," Penny gave in reluctantly.

The girls began to walk faster for they were many blocks from their own

street. Now and then they met an air raid warden and so knew that the

time for the test blackout was close at hand.

"Louise!" Penny suddenly exclaimed, stopping short.

"Now what?" the other demanded. "Don't you dare tell me you've left

something at the library!"

Penny was staring at a man who only a moment before had come through the

revolving doors of the Hotel Claymore.

"See that fellow!" she said impressively.

"Yes, what about him?"

"He's the head waiter at The Green Parrot."

"Why, you're right!" Louise agreed. "For a minute I didn't recognize him

in street clothes."

"Let's follow him," Penny proposed as the man started down a side street.

"Maybe we can learn the new location of The Green Parrot."

"Oh, Penny, I told Mother I'd come straight home."

"Then I'll follow him alone. I can't let this opportunity slip."

Louise hesitated, and then, unwilling to have Penny undertake an

adventure alone, quickly caught up with her.

"There's no telling where this chase will end," she complained. "That man

may not be going to The Green Parrot."

"Then perhaps we'll learn where he lives and police can question him."

As Penny spoke, a siren began to sound. A car which was cruising past,

pulled up at the curb and its headlights went off. All along the street,

lights blinked out one by one.

"The blackout!" Louise, gasped. "I was afraid we'd be caught in it. Now

we'll lose that man, and what's worse, I'll be late in getting home!"

CHAPTER

15

_A DRIFTING BARGE_

Upon hearing the shrill notes of the air raid siren, the man whom Penny

and Louise followed, quickened his step. Hastening after him, the girls

turned a corner and came face to face with an air raid warden.

"Take shelter!" he ordered sternly. "The closest one is across the

street--the basement of the Congregational Church."

Penny started to explain, but the warden had no time to listen. Waving

the girls across the street, he watched to see that they actually entered

the shelter.

"I guess he thought we weren't very cooperative," Louise remarked as they

followed a throng of persons downstairs to the basement. "These blackout

tests really are very important."

"Of course," agreed Penny. "It's a pity though that our friend, the

waiter, couldn't have been sent into this same shelter. Now we'll lose

him."

For nearly twenty minutes the girls remained in the basement until the

All Clear sounded. As they returned to the street level, lights were

going on again, one by one. Pedestrians began to pour out of the

shelters, but the girls saw no one who resembled the waiter.

"We've lost him," sighed Penny. "I guess we may as well go home."

"Let's hurry," urged Louise who was glad to abandon the pursuit. "Mother

will be worried about me."

At the Sidell home, Penny turned down an invitation to come in for a few

minutes. As she started on alone, she paused and called to her chum who

was on the porch: "Oh, Lou, how about a sail early tomorrow morning?"

"Isn't the river too high?"

"It was dropping fast this morning. The current's not so strong now

either. Let's get up bright and early."

"How early?" Louise asked dubiously.

"Oh, about seven o'clock."

"That's practically the middle of the night," Louise complained.

"I'll come by for you at a quarter to seven," Penny said, as if the

matter were settled. "Wear warm clothes and don't you dare keep me

waiting."

The next morning heavy mists shrouded Riverview's valleys and waterfront.

Undaunted by the dismal prospect, Penny proceeded in darkness to the

Sidell home. There, huddling against the gate post, she whistled several

times, and finally tossed a pebble against the window of Louise's room. A

moment later the sash went up.

"Oh, is it you, Penny?" her chum mumbled in a sleepy voice. "You surely

don't expect to go sailing on a morning like this!"

"The fog will clear away just as soon as the sun gets up. Hurry and climb

into your clothes, lazy bones!"

With a groan, Louise slammed down the window. Ten minutes later she

appeared, walking awkwardly because she wore two pair of slack suits and

three sweaters.

"Think we'll freeze?" she inquired anxiously.

"You won't," laughed Penny, giving her a thermos bottle to carry.

By the time the girls reached the dock, the rising sun had begun to

scatter the mist. Patches of fog still hung over portions of the river

however, and it was impossible to see the far shore.

"Shouldn't we wait another hour?" Louise suggested as Penny leaped aboard

the dinghy.

"Oh, by the time we get the sail up the river will be clear," she

responded carelessly. "Toss me the life preserver cushions."

While Penny put up the mainsail, Louise wiped the seats dry of dew. Her

fingers stiff with cold, she cast off the mooring ropes, and the boat

drifted away from the dock.

"Well, the river is all ours this morning," Penny remarked, watching the

limp sail. "That's the way I like it."

"Where's the breeze?" demanded Louise suspiciously.

"We'll get one in a minute. The headland is cutting it off."

"You're a chronic optimist!" accused Louise. Wetting a finger, she held

it up. "I don't believe there is any breeze! We'll just drift down stream

and then have to row back!"

"We're getting a little now," said Penny as the sail became taut. "Hold

your fire, dear chum."

The boat gradually picked up speed, but the breeze was so unsteady that

the girls did not attempt to cross the river. Instead, they sailed in

midstream, proceeding toward the commercial docks. The mists did not

entirely clear away and Penny began to shiver.

"Don't you wish you had one of my sweaters?" asked Louise, grinning.

Penny shook her head as she reached to pour herself a cup of steaming

coffee from the thermos bottle. Before she could drink it, a large, flat

vessel loomed up through the mist ahead.

"Now don't try to argue the right of way with that boat," Louise advised

uneasily.

"Why, it's a barge!" Penny exclaimed, bringing the dinghy about. "I do

believe it's adrift!"

"What makes you think so?" Louise asked, staring at the dark hulk.

Penny maneuvered the dinghy closer before she replied. "You can see it's

out of control. There's no tow boat anywhere near."

"It does seem to be drifting," Louise acknowledged. "No one appears to be

aboard either."

Realizing that the large vessel would block off all the wind if she

approached too close to it, Penny kept the dinghy away. The barge, almost

crosswise to the current, was floating slowly downstream.

"How do you suppose it got loose?" Louise speculated.

"Saboteurs may have cut the hawser."

"The big mooring rope _has_ been severed!" Louise exclaimed a moment

later. "I can see the frayed end!"

Penny came about again, tacking in closer to the drifting vessel.

"That certainly looks like the barge Carl Oaks was hired to guard," she

declared with a worried frown. "Can you read the numbers, Lou?"

"519-9870."

"Then it is his barge!"

"He must have deserted his post again."

"In any case that barge is a great hazard to other vessels," Penny

declared, deeply troubled. "Not even a signal light on the bow or stern!"

"Oughtn't we to notify the Coast Guards?"

"We should, but while we're reaching a telephone, the barge may ram

another boat. Why not board her and put up signal lights first? In this

fog one can't see a vessel many yards ahead."

"It doesn't look possible to climb aboard."

"I think I can do it," Penny said, offering the tiller to her chum.

"Here, take the stick."

"You know what happens when I try to steer," Louise replied, shrinking

back. "I'll be sure to upset. The wind always is tricky around a big

boat."

"Then I'll take down the sail," Penny decided, moving forward to release

the halyard.

The billowing canvas came sliding down. Penny broke out the oars, and

maneuvered the dinghy until it grated against the hull of the barge.

"Even a trained monkey couldn't get up there," Louise declared, staring

at the high deck.

Penny rowed around to the other side of the barge. Discovering a rope

which did not give to her weight, she announced that she intended to

climb it.

"You'll fall," Louise predicted.

"Why, I'm the champion rope climber of Riverview High!" Penny chuckled,

thrusting the oars into her chum's unwilling hands. "Just hold the dinghy

here until I get back."

"Which shouldn't be long," Louise said gloomily. "I expect to hear your

splash any minute now."

Penny grasped the dangling rope. With far more ease than she had

anticipated, she climbed hand over hand to the deck of the barge. Once

there she lost not a moment in lighting signal lamps at bow and stern.

The task accomplished, she was moving amidships when she thought she

heard a slight sound from within the deck house. Pausing to listen, she

called:

"Is anyone here?"

There was no answer, but distinctly she heard a scraping noise, as if

someone were pushing a chair against a wall.

"Someone _is_ in there!" Penny thought.

Darting across the deck, she tried the door of the cabin. It had been

fastened from the outside. Fumbling with the bolt, she finally was able

to push it back. The door swung outward.

For a moment Penny could discern no one in the dark, little room. Then

she saw a man lying on the floor. A gag covered his mouth and his hands

and feet were tied with cord.

The prisoner was Carl Oaks.

CHAPTER

16

_DANGER ON THE RIVER_

Throwing the door open wide to admit more light, Penny darted into the

cabin. Bending over the prisoner, she began to untie the cords which

bound his wrists.

"I'll have you free in a minute, Mr. Oaks," she encouraged him.

The cords had been loosely tied. Undoing the knots, she next pulled away

the gag which covered his mouth.

"What happened, Mr. Oaks?" she demanded. "Who did this to you?"

The old watchman sat up, stretching his cramped arms. He did not reply,

but watched Penny intently as she loosened the thongs which bound his

legs. Getting up, he walked a step or two across the cabin.

"Tell me what happened," Penny urged impatiently. "Don't you feel able to

explain?"

"I'm disgusted," Mr. Oaks returned. "Plumb disgusted."

"I don't doubt you feel that way," agreed Penny. "This barge is floating

in mid-channel, a hazard to incoming and outgoing vessels. We'll have to

do something about it."

"I'm through with this job! I didn't want it in the first place!"

"That's neither here nor there," Penny replied, losing patience. "Suppose

you stop grieving over your bad luck for a minute, and explain what

occurred."

"Well, it was about midnight when they sneaked aboard."

"The men who attacked you?"

"Yes, there were three of 'em. I was in the cabin at the time, reading my

newspaper. Before I knew what was happening, they were on top of me."

"Did you recognize any of the men, Mr. Oaks?"

"No."

"What did they look like?"

"It was dark and I didn't see their faces."

"How were they dressed?"

"Didn't notice that either," Mr. Oaks returned grumpily. "I was too busy

tryin' to fight 'em off. They trussed me up and then cut the barge

loose."

"Saboteurs!"

"Reckon so," the old watchman nodded.

"Well, what will we do?" Penny asked, scarcely able to hide her growing

irritation. "It's still foggy on the river. I've put up signal lights,

but an approaching freighter might not see them in time to change her

course."

"There's nothing more to be done," Carl Oaks responded with a shrug. "The

Coast Guard boat will come along after awhile. I'm not going to worry

about it--not me! I'm done with this lousy job, and you can tell your

father so."

"My father can bear the shock, I think," Penny answered coldly.

Thoroughly disgusted at the indifferent attitude of the watchman, she ran

out on deck. Looking down over the side, she saw Louise waiting anxiously

in the dinghy.

"Oh, there you are!" her chum cried. "I thought you never were coming!"

Penny explained that she had found Carl Oaks lying bound and gagged

inside the deck house. As the old watchman himself came up behind her,

she could say nothing about his indifferent attitude.

"I wondered how you got out to this barge," Oaks commented, gazing down

at the dinghy. "You can take me to shore with you."

"Isn't it your duty to remain here until relieved?" Penny asked.

"I resigned, takin' effect last night at midnight," Oaks grinned. "I've

had enough of Riverview. I'm getting out of this town."

Penny faced the watchman with flashing eyes.

"My father obtained this job for you, Mr. Oaks. You'll show very little

gratitude if you run off just because you're in trouble again."

"A man's got a right to do as he pleases!"

"Not always," Penny corrected. "Saboteurs are at work along this

waterfront, and it's your duty to tell police what you know."

"I didn't see the men, I tell you! They came at me from behind."

"Even so, you may be able to contribute information to the police. In any

case, you'll have to stay here until relieved--"

"Penny!" interrupted Louise from below. "There's a boat coming!"

The steady chug of a motor could be heard, but for a moment the swirling

mists hid the approaching vessel. Then a pleasure yacht, with pennants

flying, came into view.

"It's the _Eloise III!_" Penny cried, recognizing the craft as one

belonging to Commodore Phillips of the Riverview Marine Club.

Waving their arms and shouting, the girls tried to attract the pilot's

attention. To their relief, the yacht veered slightly from her course,

and the engines slackened speed.

"Yacht ahoy!" called Penny, cupping hands to her lips.

"Ahoy!" came the answering shout from Commodore Phillips. "What's wrong

there? Barge adrift?"

Penny confirmed the observation and requested to be taken aboard.

Although she was not certain of it, she believed that the _Eloise III_

was equipped with a radio telephone which could be used to notify Coast

Guards of the floating barge.

Leaving Carl Oaks behind, the girls rowed to the yacht and were helped

aboard. Commodore Phillips immediately confirmed that his vessel did have

radio-telephone apparatus.

"Come with me," he directed, leading the girls to the radio room.

The Commodore sat down beside the transmitting apparatus, quickly

adjusting a pair of earphones. Snapping on the power switch, he tuned to

the wave length of the Coast Guard station. While the girls hovered at

his elbow, he talked into the radio telephone, informing the Coast Guard

of the floating barge and its position. The message, he explained to

Penny and Louise, would be received in "scrambled speech" and

automatically transformed into understandable English by means of an

electrical device.

"How do you mean?" inquired Louise, deeply puzzled.

"Nearly all ship-to-shore radio telephone conversations are carried on in

scrambled speech," the Commodore replied. "Otherwise, eavesdroppers could

tune in on them and learn important facts not intended to be made

public."

"But you spoke ordinary English into the 'phone," Louise said, still

perplexed.

"The speech scrambler is an electric circuit which automatically

transposes voice frequencies," the Commodore resumed. "The words are made

unintelligible until unscrambled by a similar device at the receiving

station. For instance, if I were to say 'Mary had a little lamb,' into

this phone, anyone listening in would hear: 'Noyil hob e ylippey ylond.'

Yet at the receiving post, the message would be unscrambled to its

original form."

"I wish our telephone at home was fixed that way!" Penny declared with a

laugh. "Wouldn't some of the neighbors develop a headache!"

Having been informed that a Coast Guard cutter would proceed at once to

the locality, the girls felt relieved of further responsibility. As

Commodore Phillips said that he would stand by with his yacht until the

cutter reached the scene, they finally decided to return to shore. Once

well away from the yacht they raised sail and tacked toward their own

dock.

"I hope the Coast Guard gives Carl Oaks a good lecture," Penny remarked,

turning to gaze back at the slowly drifting barge. "Why, he wasn't one

bit concerned what might happen to other vessels!"

"I never did like him," said Louise with feeling. "He complains too much.

Was it his fault that the barge was cut adrift?"

"Not according to his story. Three men attacked him while he was in the

deck house. Of course, he couldn't have been too alert."

"Carl Oaks wouldn't be!"

"There was one rather peculiar thing," Penny said slowly. "It never

occurred to me until now."

"What's that?"

"Why, Mr. Oaks' bonds were very loose. If he had tried, I believe he

could have freed himself."

"That does seem strange," agreed Louise. "You don't think he allowed

those saboteurs to board the barge?"

Penny brought the dinghy around, steering to avoid a floating log.

"I wouldn't know," she replied soberly. "But I'm glad we forced Mr. Oaks

to wait for the Coast Guard. I hope they question him until they get to

the bottom of this affair."

CHAPTER

17

_A STOLEN BOAT_

The mists were lifting as Penny and Louise sailed slowly past the Ottman

Dock toward their own snug berth. Sara, in blue slacks, a red bandana

handkerchief over her head, was trying to start a stubborn outboard

motor. Glancing up, she called a greeting, and then asked abruptly:

"Say, what's that barge doing out on the river? It looks to me as if it's

adrift, but I can't see well enough to tell."

Penny and Louise, eager to impart information, brought the dinghy to a

mooring at the floating platform. Sara listened with interest as they

revealed how they had boarded the barge, released Carl Oaks, and then

notified the Coast Guard.

"Neat work!" she praised. "That Carl Oaks! He's one of the most shiftless

men I ever knew. He doesn't deserve to hold a job."

Penny glanced about the dock, searching for Burt Ottman.

"Your brother isn't here?" she remarked absently.

"No, he isn't," Sara replied, rather defiantly. "If you think he had

anything to do with that barge--"

"Why, it never entered my mind!" Penny exclaimed.

"I'm sorry," the older girl apologized. "I shouldn't have said that. I

don't know why I'm so jumpy lately."

"You have a great deal to worry you," said Louise sympathetically. "And

you work too hard."

"I'll be all right as soon as Burt's trial is over. He's not here this

morning--" Sara's voice broke. "In fact, I don't know where he is."

Louise and Penny said nothing, though the remark astonished them.

"Burt was out all last night," Sara spoke and then seemed to realize that

her words easily could be misinterpreted. She added hastily: "He's been

trying to gain evidence which will prove his innocence."

"You mean your brother went away yesterday and failed to return?" Penny

asked after a moment.

Sara nodded. "He's on the trail of the real saboteurs, and it's dangerous

business. That's why I'm so worried. I'm afraid he's in trouble."

"Have you talked to the police?" Penny inquired.

"Indeed, I haven't."

"Didn't your brother tell you where he was going when he left home?"

"No, he didn't. He keeps things from me because he says I worry too much

now."

"I suppose he never explained what happened at The Green Parrot?"

"He said he couldn't remember. Oh, everything's so mixed up. I try not to

think about it, because when I do my head simply buzzes."

Once more Sara tried to start the balky engine, and this time her efforts

brought success.

"Thank goodness for small favors!" she muttered. "Now I've got to go out

on the river and look for our stolen boat. Hope no one runs off with this

place while I'm gone."

"You've not had another boat stolen?" Louise asked in surprise.

"I figure that's what happened to it. Late yesterday afternoon a man came

here and rented our fastest motorboat. That's the last I've seen of him

or it."

"Didn't you report your loss to the Coast Guards?" inquired Penny.

Sara answered with a trace of impatience. "Of course, I did. They

searched the river last night. No accident reported, and no trace of the

boat."

"The man might have drowned," Louise offered anxiously.

"It's not likely. If he had gone overboard, the boat would have been

found by this time. No, it's been pulled up somewhere in the bushes and

hidden. Last year one of our canoes was taken. Burt found it a month

later, painted a different color!"

"Didn't you know the man who rented the boat?" questioned Penny.

"Never saw him before. He was tall and thin and dark. Wore a brown felt

hat and overcoat. I noticed his hands in particular. They were soft and

well manicured. I said to myself, 'This fellow doesn't know a thing about

boats,' but I was wrong. He handled that motor like a veteran."

"The man didn't look like a waiter, did he?" Penny asked quickly.

"You couldn't prove it by me."

Penny groped in her mind to recall a characteristic which definitely

would describe the head waiter of The Green Parrot. To her chagrin, she

could think of only one unusual facial characteristic, a tiny scar on his

cheek. She did remember that the man had worn a large, old fashioned gold

watch which might have been of foreign make.

"Why, the fellow who rented the boat did have such a watch!" Sara cried

when Penny mentioned the timepiece. "I didn't notice the scar. What is

his name?"

"Louise and I never were able to learn," Penny replied with regret. "The

Green Parrot has closed its doors, so I don't know how you can get in

touch with him."

Sara sighed. Placing an oar, a bailer, and a can of gasoline in the boat,

she prepared to leave the dock.

"I'll be lucky if I ever see the fellow again," she commented. Hesitating

a moment, she asked diffidently: "Don't suppose you girls would like to

go along?"

Penny and Louise wondered if their ears had betrayed them. It seemed

beyond belief that Sara actually would invite them to accompany her.

"Why, of course, we'd like to go," Penny accepted, before her chum could

find her voice.

Scrambling out of the dinghy, the girls made it fast to the dock and

transferred to the other boat. Sara opened the throttle, and they shot

away, leaving behind a trail of churning foam. Out through the slip they

raced, rounding a channel buoy at breakneck speed.

"You can certainly handle a boat," Penny said admiringly.

"Been at it since I was a kid," Sara grinned. "I could cruise this river

blindfolded."

They passed the floating barge, observing that a Coast Guard cutter was

proceeding up river to take it in tow. Turning upstream, Sara swung the

boat toward shore.

"Keep close watch of the bushes," she directed the girls. "If you see

anything that looks like a hidden boat, sing out."

At low speed they crept along the river, watching for marks in the sand

which might reveal where a craft had been pulled out of water. Once,

venturing too close in, Sara went aground and had to push off with the

oars.

"It doesn't look as if we'll have any luck," she remarked gloomily. "The

boat's probably so well hidden, it would take a ferret to find it."

They kept on upstream toward the Seventh Street Bridge, a structure much

in use since the more modern Thompson's Bridge had been closed to auto

traffic. Penny, watching the stream of vehicles passing above, remarked

that Riverview commerce would be paralyzed should anything occur to

damage it.

"The Seventh Street Bridge now is the only artery open to the Riverview

Munitions Plant," Sara added. "I understand it's being guarded day and

night. By a better watchman than Carl Oaks, I hope."

Without passing the bridge, the girls turned downstream, searching the

opposite shore. Before they had gone far, Sara beached the boat on a

stretch of sand.

"It was along here that Burt found our canoe last year," she explained.

"If you don't mind waiting, I'll get out and prowl around a bit."

"Aren't we near Bug Run?" Penny inquired.

Sara pointed out the mouth of the stream which was hidden from view by a

clump of willows.

"If you expect to be here a few minutes, Louise and I might pay Old Noah

a flying visit," Penny said eagerly. "We're curious to learn what has

happened to him."

"I'll be around for at least half an hour," Sara replied. "Take your

time."

Penny and Louise set off along the twisting bank of Bug Run. Approaching

the vicinity of the ark, they noticed many corked blue bottles caught

amid the debris of the sluggish stream.

"I'll bet a cent and a half that Old Noah still is on the old stamping

grounds!" Penny remarked. "Sheriff Anderson probably hasn't found a way

to get rid of him. Why, unless a regular deluge floods this stream, the

ark never could be floated out to the main river."

"The sheriff could put Old Noah in jail."

"True, but a great many people would criticize him if he did."

A moment later the girls rounded a bend and saw the ark in its usual

setting. A long clothes line had been stretched from bow to stern, and

wet garments fresh from the wash tub, flapped in the breeze.

"Well, Noah is still here," chuckled Penny. "He's run up the white flag

though! Or should we say the white flags!"

On the deck of the ark, Old Noah was so busy that he failed to note the

approach of the two girls. He stood in the center of a ring of soiled

clothes, laboring diligently over a tub of steaming suds.

As the girls reached the gangplank, a dog from inside the ark began an

excited barking. Startled, Old Noah glanced up. Unnoticed by him, his

long white beard slipped into the soapy water and he rubbed it vigorously

on the washboard.

Scarcely able to control a giggle, Penny followed her chum aboard the

ark. As Old Noah kept on scrubbing his beard she could not resist asking:

"Excuse me, but aren't you washing your whiskers by mistake?"

Surprised, the old man straightened to his full height. Squeezing the

dripping beard, he carefully wrung it out. Next he produced a comb from

his loose fitting brown pantaloons, and painstakingly unsnarled the

tangles. Then turning to the girls, he greeted them with his usual

dignity.

"Good morning, my daughters. I am glad you kept your promise to visit me

again."

"Good morning, Noah," responded Penny, trying not to laugh. "We thought

we would drop by and see if you were still here. I remember Sheriff

Anderson said he was going to call on you again."

The old man's weather beaten face crinkled into deep wrinkles. "Ho, ho!

So he did, but he reckoned without the Might of the Righteous. I was

watching for him when he came."

"I hope you didn't mistreat him," Penny said uneasily.

"When I observed his approach I untied my two hounds, Nip and Tuck, and

hid myself in the forest. He was gone when I returned to the ark."

"Likewise, part of his anatomy, I suppose," commented Penny.

"Nip and Tuck did cause a commotion," Old Noah acknowledged, "but they

did him no harm. When he went away the sheriff left a cowardly note

tacked to a tree. It said he would return to dispossess me. Before that

happens, I will blow this ark to Kingdom Come!"

"How will you do that?" inquired Penny, rather amused.

"With dynamite."

"Do you have any aboard the ark?"

Old Noah smiled mysteriously. "I know where I can lay my hands on all

I'll need. When I was hiding in the woods yesterday, I saw where they

keep it."

Penny and Louise glanced quickly at each other. While it was possible

that Old Noah was talking wildly, the mention of dynamite made them

uneasy. If it were true that he had come into possession of such a cache,

then obviously it was their duty to report to the authorities.

"Who hid the dynamite?" Penny asked.

"I do not rightly know," replied Old Noah. "It may have been those

strangers who were pestering me last night. They came to my ark and were

very nosey, asking me about this and that."

"Not officers?"

"They had no connection with the Law, speaking of it with great

contempt."

"How many men were there, Noah?"

"Two."

"And they came by car?"

"Bless you, no," replied Noah wearily. "They arrived in a motorboat. Of

all the pop-poppin' you ever heard! It almost drove my animals crazy."

"After they talked to you, the men went away again in their boat?"

"They started off, but as soon as they had turned the bend they switched

out the motor. I wondered what they were up to, so I sneaked through the

bushes and watched."

"Yes, go on!" Penny urged eagerly as Old Noah interrupted the narrative

to wash another shirt. "What did the men do?"

"Why, nothing," answered the old man. "They just pulled the boat up into

the bushes and went off and left it."

"The boat is still there?" Penny demanded.

"So far as I know, my daughter."

"Will you show us where the boat is hidden?" pleaded Penny. "And the

dynamite cache too!"

"I am very busy now," Old Noah said, shaking his flowing locks. "I have

this pesky washing to do, and then, there's all the animals to feed."

"Can't we help you?" offered Louise.

"I thank you kindly, but it would not be fit work for young ladies. If

you will return tomorrow, I gladly will guide you to the place."

Penny and Louise tried their powers of persuasion, but the old man was

not to be moved. In the end they had to be satisfied with a description

of the site where the motorboat had been hidden. Old Noah stubbornly

refused to tell them more about the cache of dynamite.

Finally, the girls said goodbye to the master of the ark, and hastened

toward the river to join Sara. They were greatly excited by the

information they had obtained.

"Old Noah may have talked for the fun of it," Penny declared as they

struggled through the underbrush. "If not, I think we've stumbled into an

important clue--one which may have a bearing on the bridge dynamiting

case!"

CHAPTER

18

_PENNY'S PLAN_

Sara was waiting beside her boat when Penny and Louise came running along

the muddy shore. Without apologizing for being so late, they excitedly

related their conversation with Old Noah.

"Say, maybe that hidden motorboat is mine!" the girl exclaimed. "What did

it look like?"

"We didn't take time to search for it," Penny replied. "We knew you would

be waiting so we came straight here."

"Let's see if we can find it," Sara said, starting up the engine.

"Noah's animals don't like motorboats," Louise chuckled. "I suggest we do

our searching afoot."

"All right," Sara agreed readily, switching the motor off again. "Lead

and I'll follow."

Penny and Louise guided their companion to the mouth of Bug Run and

thence along its slippery banks to a clump of overhanging willows.

"According to Old Noah's description, this should be the place," Penny

declared, looking about. "No sign of a boat though."

Sara took off shoes and stockings and waded through the shallow, muddy

water. Whenever she came to a clump of bushes, she would pull the

branches aside to peer behind them.

"Old Noah may have been spoofing us," Penny began, but just then Sara

gave a little cry.

"Here it is! I've found it!"

Penny and Louise slid down the bank to the water's edge. Behind a dense

thicket, a motorboat had been pulled out on the sand. The engine remained

attached, covered by a piece of canvas.

"Is it your boat, Sara?" Penny asked eagerly.

"It certainly is!" She spoke with emphasis. "The hull has been repainted,

but it takes more than that to fool me."

"Any positive way to identify it?"

"By the engine number. Ours was 985-877 unless I'm mistaken. I have it

written down at home."

"What's the number of this engine?"

"The same!" Sara cried triumphantly after she had removed the canvas

covering and examined it. "This is my property all right, and I shall

take it back with me."

"Old Noah spoke of two strangers who came here last night by boat," Penny

said thoughtfully.

"The fellow who stopped at the dock probably picked up a pal later on,"

Sara commented, trying to shove the boat into the water. "My, this old

tub is heavy! Want to help?"

"Wait, Sara!" Penny exclaimed. "Let's leave the boat here."

"Leave it here! Now that would be an idea! This little piece of floating

wood represents nine hundred and fifty dollars."

"I don't mean that you're to lose the boat," Penny hastened to explain.

"But if we take it now, we never will catch the fellow who stole it."

"That's true."

"If we leave the boat here we can keep watch of the place and catch those

scamps when they come back."

"They may not come back," Sara said, without warming to the plan.

"Besides, I've no time to do a Sherlock Holmes in the bushes. I have my

dock to look after."

"Louise and I could do most of the watching."

"Well, I don't know," Sara said dubiously. "Something might go wrong. I

never would get over it if I lost the boat."

"You won't lose the boat," promised Penny. "It's really important that we

catch those two men, Sara. From what Old Noah said, they may be connected

with the bridge dynamiting."

"What makes you think that?"

"Because Old Noah found a cache of dynamite somewhere near here."

"He won't tell us its location," added Louise.

"If it should develop that the men are saboteurs, we might learn

something which would help your brother's case," Penny said persuasively.

"How about it, Sara?"

"I'd be glad to risk the boat if I thought it would help Burt."

"Then let's leave it here. We can watch the spot night and day."

"And what will your parents have to say?"

Penny's face fell. "Well, I suppose when it comes right to it, Dad will

set his foot down. But at least we can watch during the day time. Then if

necessary, we might report to the police."

"Let's leave them out of it," Sara said feelingly. "If you girls will

remain throughout the day, I'll stand the night watch."

"Not alone!" Louise protested.

"Why not?" Sara asked, amused. "I've frequently camped out along the

river at night. Once I made a canoe trip the full length of the river

just for the fun of it."

"Louise and I will stay here now while you return to the dock," Penny

declared. "Better call our parents when you get there and break the news

as gently as possible."

"What will you do for lunch?"

"Maybe we can beg a sandwich or a fried egg from Old Noah," Penny

chuckled. "We'll manage somehow."

"Well, whatever you do, don't leave the boat unguarded," Sara advised,

starting away. "As soon as it gets dark I'll come back."

Left to themselves, Penny and Louise explored the locality thoroughly.

Not far away they found a log which offered a comfortable seat, and they

screened it with brush.

"Now we're all ready for Mr. Saboteur," Penny said. "He can't come too

soon to suit me."

"And just what are we going to do when he does arrive?"

"I forgot to figure that angle," Penny confessed. "We may have to call on

Old Noah for help."

"Noah will be busy doing a washing or giving the goat a beauty

treatment," Louise laughed.

The sun lifted higher, and steam rising from the damp earth made the

girls increasingly uncomfortable. As the hours dragged by they rapidly

lost zest for their adventure. Long before noon they were assailed by the

pangs of hunger.

"If I could catch a bullfrog I'd be tempted to eat him raw," Penny

remarked sadly. "How about chasing up to the ark? Noah might give us a

nibble of something."

"Dare we go away and leave the boat?"

"Oh, it's safe enough for a few minutes," Penny returned. "The idea of

staying here wasn't such a good one anyhow. What if those men should

never come back?"

"This is a fine time to be thinking of that possibility!"

Moving quietly through the woods, the girls came to the ark. They could

hear the hens cackling, and as they called Old Noah's name, the parrot

answered, squawking: "Polly wants a cracker."

"You've got nothing on me, Polly," said Penny. "Where's your master?"

The old ark keeper was nowhere in evidence. Nor were the girls able to

board the boat, for the gangplank had been removed.

"Now if this isn't a situation!" Penny exclaimed, exasperated. "It looks

as if we're going to starve to death."

After lingering about the ark for a few minutes, they returned to their

former hiding place. By this time they were so sorry for themselves that

they could think of nothing but their discomfort. Belatedly, they

recalled that Sara had smiled as she went away.

"She knew what we were up against staying here!" Penny declared. "Figured

us for a couple of softies, I bet!"
