FIFTEEN MINUTES OF RADIO EACH DAY
BY JOSEPH CALCATERR4,
Radio Editor of Popular Science Monthly

a reduction gearing in the form Of a
large gear fastened to the shaft of
the condenser. a small gear meshine
with this large gear and turned by a
separate knob attached to it allowed
the operator to make the fine adjust
ment, because of the fact that it re-
quires many complete turns of the
knob attached to the small gear to
turn the condenser shaft to which the
large gear was attached, through a
complete revolution.
Another common form makes use
OF an extra rotary plate turned by a
separate small knob so that the rough
adjustment can be obtained by ad-
plates: which are fastened together,
and the final adjustment made with
the extra leaf or plate.
Two Methods Combined.
In still another vernier variable
condenser the two methods. are COM
bined to give a really micrometer ad-
5ustment. In this type an extra leaf
is used. The edge of this leaf, how
ever, has gear teeth cut into it and
a small gear attached to a separate
knob meshes into this separate leaf
gear. The result is that a very large
reduction is obtained, first by the
extra leaf method and then by the
gear method.
The advantage of the simple gear
type over the separate leaf type lies
in the fact that there is no series re-
sistance Of the type that sometimes
exists in extra leaf condensers whose
extra leaf members do not make very
good contact with the main set OF
plates.
Many other manufacturers have
used application of friction and
eccentric gearing to produce the
small movement of plates of con-
densers or shafts of variocouplers and
variometers, necessary to give fine
adjustments.
A more recent development has
been the design of special dials in
which a gear reduction motion is in
corporated. Such devices produce a
very small motion of the shaft to
which they are attached.
There also are various cheap but
emcfent attachments which can be
fastened on the panel and placed in
contact with present dials to give a
reduction movement.

The Development of Vernier
Adjusters.

The Importance of vernier adjust
ments in the tuning of circuits OF
receivers cannot be overestimated
Such adjusters maks it possible to
get the fine adjustments necessary to
tune the local stations in to best ad-
vantage. In attempting to receive
distant stations hey often make the
letters and announcements of the
stations and hearing merely a mum
BILE that cannot be understood.
Fans who receive a station whose
call letters they do not know, but
which they have reason to believe is
a distant station, can attest to the
exasperation which they have felt
after vainly trying to clear up recep-
tion sufficiently to enable them to
get the call letter of the station. In
many cases the use of a vernier ad-
1uster would have made 1T possible to
tune the circuits to a sufficiently fine
point to receive the station clearly.
The first instrum ent which responded
to the call of fine adjustments was
the vernier rheostat. Many arrange
mentS, such as a continuous variable
resistance wire with a slider arranged
to make contact over the whole
length of the wire; combination of
resistance elements, one to give the
Vbugh adjustment and the other to
give a fine adjustment; the various
types of carbon and graphite COM
preston types giving a fine, even ad-
justment over the entire resistance
range, and other similar types were
the result of concentrated effort to
produce a rheostat which gave the
fine adjustment required when soft
detector tubes of the UV-200 type
were used.
Vernfer Loses Popularity.
With the coming of hard tubes of
the UV-201A, C-301-A, UV-199 and
C-2ss types, which are not very criti-
cal in filament temperature adjust
ment, the vernier rheostat has more
or less dropped out of the limelight.
1t was not long before designers
became aware of the benefits to be
derived from devices which enabled
the operator to make very minute
adjustments Of the capacity and in
ductance constants in the various
circuits OF a receiver.
The variable condenser has come
IN for its share of attention and many
Interesting and ingenious arrange
ments have been developed to permit
fine adjustments on this instrument.
One of the first methods used to make
the fine adjustments was the use of

made a startled rise, but he struck

across the snow trying to rise in the
air again. AS his teeth crunched
through the tender flesh and fragile
bones, he began naturally to eat

with a sudden shock Of suspicion.
Faint, strange sounds came from
within. They were sounds not made
by his mate, and yet they, were re-
motely familiar. He bellied cauti-
ously inside and was met by a warn
ing snarl from the she wolf. This
he received without perturbation,
though he obeyed it by keeping his
distance: but he remained interested
in the other sounds-faint, muffied
sobbings and slubberings.
His mate warned him irritably
away, and he curled up and slept
in the entrance When morning came
and a dim light pervaded the lair,
he again sought after the source of
the remotely familiar sounds. There
was a new note in his mates warn
ing snarl. 1t was a jealous note. and
he was very careful in keeping a
respectful distance. Nevertheless, he
made out, sheltering. between her
legs against the length of her body.

had happened many times, yet each
time it was as fresh surprise as
ever to him.
His mate looked at him anxiously
Every little while she emitted a low
growl. and at times. when it seemed
to her he approached too near the
growl shot up in her throat to a
sharp snarl. OF her own experience
she had no memory of the thing
happening; but in her instinct, which
was the experience Of all the mothers
of wolves, there lurked memory
Of fathers that had eaten their new
born and helpless progeny. 1t mani
tested itself as a fear strong within
her, that made her prevent One Eye
from more closely inspecting the cubs
he had fathered.
But there was no danger. Old One
Eye was feeling the Urge of an i'm
pulse that was, in turn, an instinct
that had come down to him from all
the fathers of wolves. He did not
question it. nor puzzle over it. 1t

and it was the most natural thing In
the world that he should obey 1T by

family and by trotting out and away

the stream divided, its forks going
off among the mountains at right
angle. Here, leading up the left fork,
he came upon a fresh track. He
smelled 1t and found 1t SO recent that
he crouched swiftly and looked in the
direction in which it disappeared.
Then he turned deliberately and took
the right fork. The footprint was
much larger than the one his own
feet made. and he knew that in the
wake of such trail there was little
meat for him.
Half a mile up the right fork, his
quick ears caught the sound Of gnaw-
ing teeth. He stalked the quarry and
found 1T to be a porcupine, standing
upright against a tree and trying
his teeth on the bark. One Eye ap-
preached carefully but hopelessly
He knew the breed, though he had
never met it so far north before; and

tunity, and he continued to draw
near. There was never any telling

The Lair.
For two days the she-w wolf and One
Eye hung about the Indian camp.
He was worried and apprehensive, yet
loath to depart. But when, one
morning. the air was rent with the
report or rifle close at hand, and a
bullet smashed against a tree trunk
several inches from One Eyes head.
they hesitated no more. but went off
on long. swinging lope that put
quick miles between them and the
danger.
They. did not go far-a couple of
days Journey. The she-wolfs need
searched had now become inpera-
tive. She was getting very heavy
and could run but slowly. Once, in
the pursuit of a rabbit, which she
ordinarily would have caught with
ease, she kave 'over and lay down
and rested. One Eye came to her:
but when he touched her neck gently
with his muzZle she snapped at him
with such quick f1erceness that he
tumbled over backward and cut a
escape her teeth. Her temper was
now shorter than eter; but he had
become more patient than ever and
more solicitous
And then she found the thing for
which she sought. 1t was a few
miles up a small stream that in the
summer time flowed into the Mac
kenzie, but that was frozen over and
frozen down to it's rocky bottom-a
dead stream of solid white from
source to mouth. The she wolf was
trotting wearily along, her mate

She turned aside and trotted over to

storms and melting SHOWS had un-
derwashed the bank and in one place

She paused at the mouth of the
cave and looked the wall over care

other, she ran along the base of the
wall to where its abrupt bulk
merged from the softer-lined land
scape. Returning to the cave, she
entered its narrow mouth. For a
short three feet she was compelled
to crouch. then the walls widened and
rose higher in a little round cham

The porcupine rolled itself into a
ball, radiating long, sharp needles
in all directions that def1ed attack.
In his youth One Eye had once
shifted too near a similar, apparently
inert ball Of quills, and had the tail
flick out suddenly in his face. One
quill he had carried away in his muz-
ZIe, where it had remained for weeks,
a rambling flame. until it finally
worked out. So he lay down in a
comfortable crouching position, his
nose fully a foot away. and out Of
the line of the tail. Thus he waited,
keeping perfectly quiet There was
no telling. Something might happen.
The porcupine might unroll. There
might be opportunity for deft and
ripping thrust of paw into the tender,
unguarded belly.
But at the end of half on hour he
arose, growled wrathfully at the mo-
tionless ball. and trotted on. He had

past for porcupines to unroll, to

Poison Bait Effective
to Control Field Mice

BY far the most satisfactory way
of controlling field mice is by the use
of poison. The biological survey has
developed several formulas for pre-
pairing bats and directions for dis
tributing them which have been found
very effective when carefully followed.
Wherever valuable trees or plants are
to be protected it is highly desirable
to maintain at all times supply of
effective poisoned bait. This may be
accomplished through the use of bats
with moisture-resistant coatings ex-
posed in suitable containers, or sta
tiOns. When properly placed such
bats will not only destroy the resi-
dent mice but will account for all
mice that may move in from time to
time. This method of poisoning is
being followed in many eastern or
chards with very gratifying results
and makes for both efficiency and
economy.

than in the South. In the former re-

main thing Is to keep the room tenn

The general practice among South

North involves, In the absence of suit

things: Either getting the seed pota-

consequent sprouting before planting,
or the risk Of having the seed chilled,
