the connecting arm D, ard the whole
assembly is kept in its normal posi-
tiun by a spring assembly, which con
meets the arHature aSse mUly with the
supporting framework.
The free end of the lever y is CON
nected with the center of the mica
diaphragm II at the center point g.
Normally with direct current
flowing through the winding r, an
electromagnetic is formed with its
north pole at m" and a south pole a
s. or vice versa depending on the
direction in which the current is fiow-
ing.
II the poles form as shown. the IN
end of the electromagnetic will be at
tracted toward the pole OF the per-
mans mt magnet S BY the attraction Of
the unlike poles and the repulsion of
the unlike poles.
Degree Of Attraction.
The degree TO which 1t is attracted
depends on the amount of the current
flowing in the plate circuit, and con-
sequently through the winding, and
its movement is limited by the spring
adjustment which tends to keep II at
It's normal position.
Since the armature is rigidly con-
nccted with the lever +, which is. in
turn, connected with the center of the
mica diaphragm II. any movement Of
the armature causes a movement of
the diaphragm and the production Of
sound waves in the horn which is at
tached to the mouthpiece /.
Through the lever action 4 small
movement OF the arnature causes a
comparatively large movement OF the
diaphragm, giving greater volume
with no danger OF rafting.
The diaphragm assembly is very
much like the type used in the phono-
graph reproducer, type which has
been found unusually efficient.
Figure shows the appearance of a
loudspeaker in which the principle
has been used.

The internal construction OF the
phone type Of loudspeaker limits the
amount al power which can be APP
piled TO it without causing serious
distortion and noise.
The usual result of applying too
much euarEy is to cause the dia-
phragm Of the phone to strike the
polepieces of the magnet with the re-
sultant noise anr rattle which it
causes.
In most OF the common types Of
phones, there is contant pull
on the metal diaphragm because
of the attraction Of the da-
permanent magnet. The amount Of
this pull Is varied by tho action of
the plate current impulses which flow
through the coils Of wire wound
around the polepicccs causing the
diaphragm vibrations which result
in the production of sound waves.

KAHN AND VIRGIN

NEW ORLEANS, La., March IT, Cotton was strong and higher during the first half of the day but lost all It's gains and a little more in the afternoon. Good cables, bad weather, forecast of more bad weather, reports of good spot demand from good authorities and of delayed preparations were the uplifting influences. Recent sellers appeared to be good buyers on and after the open ing and the public seemed to be taking more interest in the market, largely as a result of the delay in preparation and bad weather outlook. The market, however, quieted down as soon as shorts got filled up and later lapsed into dull nes. Weakness in the stock market due mainly to progress of the bonus bill and smallness of outside buying stimulated sellers to activity in the afternoon and the market was called upon to take more selling in a few minutes than it could. It sold off 73 points for the old crop and 50 points for the new during the process of ab- sorptidn but rallied pretty well just be- fore the close. Sentiment appears to have shifted largely to the selling side again as a result of the action of the market and more pressure is likely. The weather outlook seems to be un- favorable and preparations too back ward to espouse the short side. We believe buying on the breaks Is the best policy.-Fenner and Beane.

CORN AND0ATS
 SWING UPWARDS
Blizzard Weather Helps
 To Curtail Sowing Of Oats

CHICAGO, March 17.-Corn and oats took a decided swing upward in price today and helped to rally the wheat market. Blizzard weather likely to cur tail the movement of corn and to de- lay the seeding of oats was the chief stimulating factor. All grain closed firm, corn < to 1Ac91Sc net higher; E to 1hc up and wheat showing hc to sc advance; May, $1.06h to $1.06% and July $1.07S to $1.0719. In pro- visions the outcome was to 7c decline.
 Highest prices of the day in the corn market and in oats and wheat as well came just before the close, evidence having developed that selling in ex- pectance of fall in values had been considerably overdone. The fact that a liberal increase of the foreign visible supply total failed to have much effect toward depressing the corn market did a good deal to make sentimen. cnange in favor of the buying side. From the outset two commission houses were pur- chasers on standing orders to take ad- vantage of downturns. Besides, there Was d uearlh or l1quidating saies. Rural offerings meanwhile were small and with oats showing independent strength the last hour of corn trading was largely losers rush to buy grain back.
 In the wheat market some purchas- ing was based on possibilities of a better foreign demand resulting from assumed likelihood of a reparations settlement. Some advances in quota tions at Liverpool counted also as a bullish influence here. On the other hand widespread snowfalls were deem ed a benefit of the domestic winter crop and were an evident weight on values.
 Provisions were easier owing to big receipts of hogs here. 74O00 head the year.

STOCK LETTERS

NEW YORK, N. Y., March 1!.- Bonus bill legislation and cutting Of Pan American dividend in half caused some unsettlement In prices at the open ing and many issues suffered sharp breaks extending from fractions to three or four points.
 Strength in the rails helped to stem the flood of selling and such stocks as Chesapeake and Ohio. Erie, South ern Railway were In good demand. The industrial list was spotty with Kelly Springfield, Sewart- Warner and Coca Cola showing the greatest weakness. American Can, Baldwin and Stude- baker sold off but the decline did not go far. On the other hand Industrial Alcohol showed further signs of accum- mutation while Pan American only opened down about one pc1s~ Shd held firm thereafter. National Lead advanc- ed on light volume about 4 points.
 About midday another sharp drive against industrials caused almost Il of them to recede rather violently. The higher grade issues declined with the rest. Rails and oils were not disturb ed so much and gave a fairly good account of cthemselves. Motors were under pressure all day. The sagging tendency continued throughout the afternoon, finally causing further de- clines in United States Steel, Stude- baker and the other leaders. Stop or ders were caught and while there were a few fractional rallies from 'the low points the days activities were all in favor of the bear party.-Fenner and Beane.
The Birmingham age-herald., 1924-03-18
GRAIN LETTERS

CHICAGO, H., March 17.-Wheat displayed from undertone with buying by shorts and spreaders but, early weakness in corn had a depressing in- fluence and prevented any important advance. There were no indications of important liquidation at the same time, very little of the buying suggested new investment interest. United States wis., ible decreased 75o.0oo bushels for the week. Weather favorable for winter wheat with additional snow and rain reported, but unfavorable for spring wheat because of low temperatures and lack of moisture over the northwest. Government report on intended spring crop acreage will be issued sometlme after the close tomorrow.
 Corn-Turned strong late as early sellers covered and found that rest ing orders on the early decline had taken much of the surplus out of the pit. Cash basis steady to hc easier belt and a slowing up of the move ment was expected to result. United States visible increased 2,595,000 bushels for the week. Mill feeds are in slow demand.
 Oats--Strong commission house buy ing developed late and the market showed considerable firmness. Selling was scattered. Cash market relatively steady to Ac better. United States visible increase 10000 bushels for the week. Seeding of the new, crop has been delayed and present weather with fairly general snows are expected to further retard getting crop into the ground.-Fenner & Deane to Kahn & Virgin,
The Birmingham age-herald., 1924-03-18
COTTON LETTERS

NEW ORLEANS, March 17.-Cotton bulged about 40 points in the early trading on a strong showing by Liver pool, more bad weather and favorable foreign news. But drygoods reports continued favorable, but the stocks mar ket turned easier during the afternoon causing our market to weaken consid- erable.
 The morning high presented an ad- vance of more POO points on the near position from the recent lows. Good exports at 47,0o0 bales for the day, and belated reports of improved drygoods demand in Worth street were not enough to stop the selling. There was a report of considerable acreage up around Brownsville, but this was thought to be aggregated. The report of improved demand in Worth street was discredit- ed by the heavy selling.
 The government report on weevil sur vey was expected today but midday wires said it would not be issued until after the close. This report may be several days coming. Some fairly large accounts were reported liquidated dur ing the morning which had a bearish effect.
