twice the diameter Of the wire used
in winding it.
The next step is to find the length
of the circumference of the tube you
are going to use and the circumfer-
ence of the tube of the desired diam
eter. The length of the portion you
will have to cut from the larger tube
to obtain one of the desired diameter
is equal to the difference between the
two circumferences.
You can find the circumference of
each tube by multiplying the outside
diameter of each by 3.14.
By subtracting the smaller circum-
ference from the larger one you will
find the length of the arc which must
be cut from the larger tube in order
to bring it down to the smaller size. SO
that when the two cut edges of the
tube are brought together the diam
eter of the finished tube will be of the
size desired
After the length is scribed on the

BARBADOS BANS RADIO,
Use of Receiving Sets Prohibited
by Law

The use Of radio receiving sets by
individuals in Babados has not devel-

MARKET FOR RECEIVERS,
Two Broadcasting Stations Now
Operating in Bilbao.

In Bilbao two broadcasting stations
were recently put into operation. a
good market for receiving sets, chiefly
OF the crystal type, resulted. Most OF
the radio apparatus on this market is
of British and French origin, due prin-
cipally to the fact that local dealers
prefer TO carry a limited stock and
make frequent small purchases. This
practically prohibits the radio dealers
in Bilbao from purchasing their sup
plies in distant markets
That this situation does not obtain
throughout the entire kingdom is evi.
denced by the fact that during the
first quarter of 1925 Spain was the
leading European market for Ameri
can radio manufacturers. During that
period shipments of radio apparatus
from the United States to Spain to-
tailed S10S,370.

are showing more confidence in the fu-
ture by purchasing for later delivery.
The grain trade was not surprised
by the Government wheat estimates Of
July /. which showed that Spring
wheat had gained, while Winter wheat
had lost.
Big Corn Crop Surprises.
The corn estimates were a distinct
surprise. They showed the third
largest crop in the history of the coun-
try. a crop in excess of 5000, 600, 900
bushels.
The corn market had evidently ad-
justed itself to these predictions partly
because of the small carryover from
the previous year and partly on ac-
count of the speculative idea that the
season is at hand when the corn crop
ordinarily deteriorates.
Non-Ferrous Metals Up.
Higher prices were reported for the
non-ferrous metals-copper, zinc and
tin. The hide and leather market was
stronger and more active In the iron
and steel trade closer balance was
established between output and con-
sumption and, therefore, prices were
Steadier.
The steel situation is undoubtedly
on the mend, and this is beginning to
show in the market movement of the
steel stocks. But there are still the
statements for the second quarter to
get out of the way, and these are not
expected to be favorable
The European exchanges have done
little during the course of the last
week. 1t may be that the American
loans to France and to Italy have
been used for supporting purposes. al
though there is no clear proof of this
being the case.
Foreign Exchange Better.
But at all events the situation has
been improved decidedly by the frank
acknowledgement on the part of the
new French government of the fact
that there could be no real balancing
of the budget until the war loans to
Great Britain and the United States
were taken care of and until the
financing of the short-term bonds was
provided for.
With Italy the position is still OBJ
scure. How much the recent decline
in the Ira has been due to political
uncertainties and how much to eco-
nomic uncertainties remains a ques-
ton. Both factors in all likelihood
Italy has done more than other coun-
tries to overcome the inflationary
tendency and thereby to help the value
of the paper currency.

BY STUART p. WEST.

Special Dispatch to The Star.
NEW YORK, July 11.-During the
week just passed prices on the stock
exchange made a new high record.
They stood at $T0.32 on the average,
which meant a gain of S7.44 a share
since the first of the year. These
stock records were accompanied by
new high prices for United States
Treasury loans and for one or two or
the Liberty issues.
The high prices were not due to any
change in money conditions. The
money market did what was expect

stood at the beginning of the last week

Bond Break Is Surprise.
Why bond prices should have re-
acted the way they did in the middle
of the week was a matter of surprise.
Runlors regarding a change of per-

have been responsible for the selling

pointed rather to lower than to higher
money quotations.
Week End Opinion Divided.
The week ended with opinions di-
vided concerning the stock market.
Some thought that operations for the

in the same manner that they have for

stress upon the breaking ex-
pansion in brokerage loans and upon
the extended position of the specula-

Thus, while 2,0T5,0 persons left
the farms last year, 1896, 900 returned
to them, and these, with the natural
increase of births over deaths of
497 900, reduced the loss in farm popu-
lation to 1000.
Although the balance is still in
favor of cityward migration, the fig

How to Make Tubes of Any Desired
Diameter.

It is often necessary IN radio to get
materials of special size to suit con-
ditions. In many cases the special
size is not available, and the cost in
money and delay of having special
piece made is more or less prohibitive.
Under such circumstances your in
genuity must be used to find whether
it is possible TO adopt or change stand
ard material to suit your special re
quirements.
Tubing used to wind coils of various
sizes and shapes is a case IN point.
In many cases it is desired to have
tubes that fit snugly into one another
either for winding concentric windings
or for any other purpose when a tube
slightly smaller than another is de-
sired.

size available being too small, some
means must be used to find something
