<h2>CHAPTER XVIII</h2>
<h3>A STARTLING DISCOVERY</h3></div>
<p>The cook had supplied the radio boys with a
lavish hand, but their long walk and the swim
had given them ravenous appetites, and by the
time they finished there was little left of the
lunch. Even this little was soon disposed of by
the bright-eyed birds that ventured close in pursuit
of the tempting bits. By sitting as still as
statues the boys succeeded in enticing the little
fellows almost within arm’s length, and derived no
little amusement at the evident struggle between
greed and caution.</p>
<p>But soon the last crumb was gone, and after
a short rest the lads began to think of returning
to camp. They did not want to go back by the
same road over which they had come, however,
so decided to follow the shores of the lake until
they should find some other path. This was, of
course, a roundabout way of getting home, but
they had the better part of the afternoon before
them, and were in no particular hurry.
<span class="pagenum"><SPAN name='page_152' name='page_152'></SPAN>152</span></p>
<p>“Come on over to the north,” suggested Joe.
“I think there is another trail in that direction.”</p>
<p>“Yes, and I imagine the walking is better,” put
in Herb.</p>
<p>“Say, you don’t want to go too far out of the
way,” came hastily from Jimmy. “We’ve got to
walk back remember.”</p>
<p>“Forward it is!” cried Bob. “Come on, Jimmy,
you’ve got to walk off that big lunch you stowed
away.”</p>
<p>“Gee, if I walk too far I’ll be hungry again
before I get home,” sighed the stout youth.</p>
<p>“Wow! hear Jimmy complain,” burst out Joe.
“He hardly has one meal down than he’s thinking
of another.”</p>
<p>To find another trail was not as simple a matter
as it had seemed, and they must have traveled
over two miles before Bob’s keen eyes detected a
slight break in the dry underbrush that might
denote a path such as they sought. They found a
dim trail leading in the general direction in which
they wished to go, and set out at a brisk pace,
even Jimmy being willing to hurry as visions of
the loaded supper table floated before him.</p>
<p>Gradually the path widened out, as others ran
into it, until it became a fairly well-defined woods
road. It was thickly strewn with last year’s soft
and rotting leaves, and the boys made little sound
in spite of the rapidity of their pace. Bob and
<span class="pagenum"><SPAN name='page_153' name='page_153'></SPAN>153</span>
Joe and Herb were striding along in a group,
Jimmy having dropped behind while he fixed
a refractory shoe lace, when suddenly Bob halted
abruptly and held up a warning hand. The
others, scenting something amiss, stopped likewise,
looking inquiringly at Bob.</p>
<p>Silently he pointed to a spot slightly ahead of
them and several paces off the road. Even as
the others gazed wonderingly, Bob beckoned them
to follow and slipped silently into the brush that
lined the road.</p>
<p>On the other side stood a big tree, its trunk and
branches sharply outlined against the clear sky.
At the base of this tree, with his back toward
them, stood a man. Now, the surprising part of
it all, and that which had caused the boys to proceed
so cautiously, was the fact that the man
wore headphones and was evidently receiving a
message of some kind. Fastened to the tree was
a box, which evidently contained telephonic apparatus.
At first the boys thought he must be
listening at an ordinary telephone, but the fact
that he had no transmitter indicated that he was
listening in on a radio receiving set.</p>
<p>The boys had hardly reached their place of concealment
when the man turned sharply about,
darting furtive glances here and there, evidently
in search of possible intruders. The boys
crouched lower behind the bushes and prayed
<span class="pagenum"><SPAN name='page_154' name='page_154'></SPAN>154</span>
fervently that Jimmy would not arrive before the
man had gone. The fellow was of fair size, with
a deeply tanned face, and wore a moustache.
Fortunately, after they had been watching him a
few minutes, he removed the earphones, placed
them in the box, and, after locking it, started into
the woods, following a dimly marked footpath.</p>
<p>It was well that he left when he did, for not two
minutes later Jimmy came puffing along, looking
anxiously for the others. He stopped in amazement
when he saw his friends emerge from the
bushes, and was about to raise his voice in vehement
questionings when Bob leaped at him and
clapped a hand over his mouth.</p>
<p>“Be quiet!” he hissed into his ear. “There’s
some funny work going on here, and we want to
find out what it is.”</p>
<p>Thus admonished, Jimmy was released, and in
low tones the others told him of what they had
seen and showed him the box fastened to the tree.
While they were about it, they made a hasty
search for the antenna, and found it strung close
to the trunk of the tree, extending from the top
almost to the roots. After this discovery they
hurried after the man with the moustache, fearful
lest they should lose his trail.</p>
<p>It was no easy matter to follow the dimly
marked path, for it passed at times over stony
<span class="pagenum"><SPAN name='page_155' name='page_155'></SPAN>155</span>
ground and big boulders, where often it took much
searching here and there before they picked up its
continuation.</p>
<p>“We may be taking all this trouble for nothing,”
said Bob, after one of these searches.
“Maybe he’s just a lumberman receiving instruction
by wireless from his employers. Big business
firms are using radio more and more for
such purposes.”</p>
<p>“I didn’t like the way he kept looking about
him, as though he had something to conceal,” objected
Joe. “It can’t do any harm to see where
he goes, anyway. We may find out something
important.”</p>
<p>“His hands weren’t those of a lumberman,” observed
Herb. “Those hands never saw rough
work nor, judging from the man’s face and manner,
honest work. Come on, fellows.”</p>
<p>Accordingly the boys followed the difficult trail
with untiring patience, and at last their perseverance
was rewarded. The path widened out into a
little clearing, and at the further side of this was
a rough log cabin. The little shack had two small
windows, and with infinite caution the boys approached
until they could see into the nearest one.</p>
<p>The interior was rudely furnished with a heavy
table and two crudely fashioned chairs, while in
<span class="pagenum"><SPAN name='page_156' name='page_156'></SPAN>156</span>
the corner furthest from them two bunks had
been built, one above the other. In another corner
was a compact radio transmitting set.</p>
<p>At the table was seated the man with the
moustache, intently studying a notebook propped
up before him. From this he made notes on a
sheet of paper, scowling at times like one engaged
in a difficult task. At length he shoved back his
chair, rose to his feet, and, striding across the
little shack, carefully placed the notebook under a
board on a shelf. Luckily he was so absorbed in
what he was doing that he did not even glance
toward the window where the radio boys were
observing his every motion.</p>
<p>But Bob now judged that they had seen enough,
and he wished to run no unnecessary risk of detection.
At a signal from him they made for the
underbrush at the edge of the clearing, where they
could command a view of the door, and waited to
see if the mysterious stranger would emerge.</p>
<p>In a few minutes the door opened and the man
stepped out, stopping to fasten it securely behind
him. Then, with a quick glance about the little
clearing, he made for the path leading to the main
road and in a short time the sound of his going
died away.</p>
<p>The boys waited a few minutes, thinking that
possibly he might return for something forgotten,
but no further sound came from the path. At
<span class="pagenum"><SPAN name='page_157' name='page_157'></SPAN>157</span>
length they ventured to approach the deserted
cabin.</p>
<p>The door had been fastened with a heavy padlock,
but this was not sufficient to deter the radio
boys. Searching through their pockets for some
implement with which they could undo the lock,
Jimmy discovered a stout fish-hook, and after
they had ground off the barbs against a flat stone
this made an ideal tool. With it Bob probed about
in the interior of the padlock, and at length, with
a sharp click, it sprung open. Ordinarily he
would not have done this, but he had every reason
to believe that he was dealing with a criminal and
that he was justified in the interest of law and
order in taking steps that would prevent any
further depredations against society.</p>
<p>“More ways than one of killing a cat,” remarked
Bob, as he pushed open the heavy door
and entered the cabin. “We’ve got to know
what’s in that notebook before we leave this place.
Let’s have a look.”</p>
<p>The boys quickly brought the book from its place
of concealment and carried it to the table, where
they bent eagerly over it as Bob turned the pages.</p>
<p>“It doesn’t look like sense to me,” complained
Jimmy. “I never saw such a lot of fool words
jumbled together.”</p>
<p>“Yes, but something tells me there’s method in
this madness,” said Bob, his brows knit as he
<span class="pagenum"><SPAN name='page_158' name='page_158'></SPAN>158</span>
concentrated on the problem before him. “Say,
fellows!” he exclaimed, as sudden excitement
gripped him, “do you remember those nights we
were listening to our big set and we heard the
mysterious messages? They were just a lot of
words, and we couldn’t make anything out of
them at the time.”</p>
<p>“You bet I remember!” exclaimed Joe. “I
think I could even tell you most of the words.
Why, there’s some of them in that book, right
now!”</p>
<p>“Exactly,” replied Bob, nodding. “I remember
them, too, and this must be the key to the code.
My stars, what luck! Let’s see how close we can
recall the words we caught, and then we’ll see if
we can make sense of them with the help of this
key.”</p>
<p>“I’ll tell you the words as I remember them,
and you check me up,” suggested Joe, and this
they accordingly did.</p>
<p>Between them they managed to get it straight,
just as they had heard it, “Corn-hay-six-paint-water-slow-sick-jelly.”</p>
<p>“I think that’s right,” said Bob. “Anyway,
we’ll see if it comes right with the key. You read
the words, Joe, and I’ll find them in this notebook
and you can write them down. Shoot the
first one.”</p>
<p>“Corn,” said Joe.
<span class="pagenum"><SPAN name='page_159' name='page_159'></SPAN>159</span></p>
<p>Bob hunted rapidly down the columns of code
words and their equivalents, and soon found the
one he was after.</p>
<p>“Motor truck,” he read out.</p>
<p>“That sounds promising!” exclaimed Joe.
“The next word I’ve got is ‘hay.’ What’s the
answer to that?”</p>
<p>“Silk,” said Bob, after a shorter search this
time.</p>
<p>“Six,” read Joe.</p>
<p>“Castleton Road!” exclaimed Bob, his voice
shaking with excitement as he traced down the
columns of words. Herb and Jimmy were also
excited; especially the former, as he realized better
than the others how serious a loss the theft
of his father’s truckload of silk had been and
now thought he saw some clue in this message that
might throw light on the whereabouts of the
stolen goods.</p>
