But true efficiency is more than this. It is securing' the greatest result with the least con sumption of energy and at the LOWEST COST. A Tacuum tube Y4th a radium electrode would be tore .efficient than one with a Oorium filament, for it would re- ' quire no filament battery supply. Jfut such a tube would cost an immense fortune and hence it would not fall within our defini tion of ; efficiency, , There are, however, more practical methods of 'reducing radio sets operating costs, which in some cases may re sult In savings amounting to 75 XZLSSS&V annum. : v , Tubes and Batteries Chief Upkeep ' tfbvipttsly," the two items which Contribute most to the upkeep ex pense a radio set are the tabes ai'dlbd' batteries.

To one uninitiated1 in this process, it may appear a difficult operation, but it is,1 in practice, a very simple mat ter. Through! the use of a "C" battery or by taking advantage of the voltage drop across the fila ment rheostat,! a substantial sav ing In B battery current may be effected. Let j us see what this amounts to. I it.:. As we have seen, our receiving system has for its general object, to produce the greatest variations In plate current possible with a given signal. Whether these 'var iations take place about a small or large plate current is immater ial, so long as they are faithful reproductions I of the broadcast program. . j 1 . i :, The Immediate cause of varia tions in the plate current is vary ing voltages on the grid of the tube. As the grid voltage falls the plate current falls proportion- j ately likewise, when the grid be comes more positive, the plate current Increases. . Use Most Economical Size of B Battery ; v. ' . r 1 ... j Tvo factors enter into the cost j of B battery manufacture. - One i Is materials; i the other is the me-chanK-ajt wrjrirsMy? ' w-Mf is of ''OlrJ?'p governed by labor i-os-ii. '' ObrionVy,- tbe.-tarser the size, of B battery, the greater the cost of materials. On the other hand, the number of operations in, making the smallest 4 'volt B battery is approximately the same as that i encountered in making the largest size of 4 volt B bat tery. Consequently there is a considerable saving effected In the purchase of a larger size battery, when a smaller one does not give economical service. It is not pos sible, however, to prescribe bat teries of a certain size for sets having a certain number of tubes, because one factor entirely in the control of the user enters into the question. That point is the num ber of hours per week the set is used.; j One important factor in the life of a battery is the current drain to which it is subjected. Radio Cells are designed for small cur rent drains over an extended per iod. A table given herewith in dicates the current drain per tube for the various plate voltages and grid potentials usually employed, as determined by the C battery. Multiply it by the number of tubes in your set and you can readily calculate the B battery drain. This will serve as a rough index to B battery selection. ? irtrafr !!( Cm r re t ( Ml 11 lnaprea - , ifi B Battery VqHc Tb Grid Volu t2H era 80 1 .? t-74 WTM1.C-11 nd 9 11 15 VD-12.C-13 iH -.J 1 i . i.ts trv-i9 JKi 1 i t 4 C4S9 uv-wo d 1 .71 c-soo !

One enthusiastic i listener en thusiastic when not purchasing new B batteries found it neces sary to buy three sets of a small type of vertical battery per year costing $1.75 each. His plate voltage being 90, he was spending $25 a year. By substituting two large batteries costing $7.50, in dications at the end of the ninth month are that they will last fully 1 or 12 months. This simple step made him permanently enthu siastic about radio. What One User Saved Some time ago, a case of waste ful upkeep came to my attention, which is well worth. " citing. Radio had proved so troublesome that the owner of this set had about decided to give up radio. Hardly a week passed that he did not need a new tube or new B batteries, or to recharge his- A battery. When I told him that I used a six tube set at least two hours daily and that B batteries lasted at least six months and tubes a year, he was astounded. My friend had a! self contained receiver of very excellent con struction, f It employed four UV 201 A tubes, one radio, detector and two audio. At a voltage of 5.0 on the filament, its current drain was 10 milliamperes. Through the addition of a C bat tery, reduction of filament voltage from 5.0 ; to 4.0, not only was quality 6r reception greatly im proved, but B battery drain re duced to a mere 2 milliamperes. This saving of 75 per cent not only effected B battery upkeep cost, but also tube renewals and A battery erpense. Those who find radio expen sive should answer these ques tions: j 1. Am ' I using minimum fila ment voltage? 2. Am -I taking advantage of the savings possible through the use of a C battery? 3. Am I using the minimum plate voltage which will give a satisfactory signal? 4. Am I using the most econ omical size of B battery? i 5. Am ; I buying a battery of reputable' make? ' . If your answer to all of these questions is in the affirmative. you can buy a new receiving set every year out of your savings.

Now every in fdlcation points to a reversal of the order. Instead of .more elab orate super-receivers to pick-up and magnify I weak signals, ' the trend is toward super-broadcasting with power increased so that dis tant signals I can be brought In by even the simplest receivers. The development of transmis sion during the fyear will be along three well-defined lines, two of which will involve super-power. The third is national broadcasting through the interconnection . of broadcasting stations by means of telephone land wires. All thre systems will be experimental jn character at first, proceeding ac cording to recommendations ' of the Third National-Radio Confer ence in Washington, AD C. Thus the use of super-power will ".be subject to immediate cancellation, should the fears of those who say It will tend to create a monopoly of the air materialize... The first plan under the super power scheme Involves the erec tion of high-powered broadcasting stations at points removed from any thickly populated area.

The third system is the Inter- ccnectlon of all existing broadcast ing stations by means of a i net work of land telephone wires. Another Important development in broadcasting that , wjll affect every radio an during the coming year Is the rezonlng of the coun try, which will be divided Into six broadcasting zones instead of five. Under this plan the northwestern Atlantic states will have stations operating on the same wave length as stations in Pacific .Coast states. This can, be done without inter ference because of the. great dis tance between the stations and also because there! is a "time dif ference of three hours between the two coasts. ; An increase In the broadcast wave-length band to Include wavea down to 200 meters and up to 550 meters means that the radio fan who Is buying or building a new set should make sure that it will tune. 1 COS HATCHERY T MEN TO OHIZE They Will Meet at Seattle on the 29th, to Make Ar--rangements for This For several years the outstand ing national organization of poul trymen has been the Baby Chick, association. It was through this association that express rates and parcel post? shipping of baby chicks were made possible. Each year a few of the coast hatchery men have journeyed to the east or middle west to attend the an nual meeting of this national as- HISTORIC OXFORD sociation and have returned en thuaed with the organization's ac complishments. Many have ex pressed the desire of organizing a coast association that would af filiate with the internationl. Now the opportunity is here and should be taken advantage of by all who are Interested in the baby chick business. Mr, Jay Todd, manager of the Queen Hatchery, Seattle, has. at the request of Mr. H. H. Knapp. president of the . Interna tional association, called a meet ing of the hatchery men In Seat tie on the 29th of December for the purpose of forming a coast baby chick association, to affiliate with the International. Mr. Knapp is now on the coast and. will at tend the meeting to assist with the organization. The meetine is called for 10 o'clock in the assem bly room -of the Fry hotel, Seattle Washington. 1 LONDON, Dec. 20 England's first venture in silver fox farming Is to get under way shortly, and already 20 pair of foxes have been brought here from Canada and Installed on a plot of ground near Oxford. The 40 animals, which will be used for breeding purposes, i are valued at $40,000. The promoter of the enterprise,, a former Cana dian army officer, believes that the climate of England is Ideally suited to the rearing of silver foxes, and hopes to expand; his farm to Include several hundred foxes within the next year or so.

Patrick chief of the air service of the United States army, believes that air craft trans portation systems for passengers, mall and goods can, under proper conditions, compete for Bafety and reliability with the standards of railway train service or even sur pass them. lie made that state ment thi3 afternoon to the 18th annual convention of the Associa tion of Life Insurance Presidents In urging life Insurance companies to give consideration to the grant ing of insurance at regular prem iums on the lives of travelers by air and the operators of aircraft. declaring also that such Insurance would greatly aid the development of air transportation. General Patrick, who" learned to "fly when about 60 years old, often uses the air ship to save time in the trans action of his official duties. "When invited to address , this meeting I must confess that I was somewhat cheered -and elated by the knowledge that an association of insurance men was at last will ing to take some kind of a chance on an aviator. For my part I am going to venture the bold state ment that before very long air traffic, air transportation, will be on. a par with other transporta tion insurance risks; otherwise history will have reversed Jtself. Speaks on Development, "i want to touch for just a mo ment upon the military phase of the development and use of air craft. The experience of the World war has convinced all who have studied the matter that in future wars aircraft will play an impor tant or possibly a decisive part; that the only adequate and effec tive defense against an air attack is an air force of your own; and hence such an air force properly equipped, highly trained, muet be part of our military establish ment. So far as our national safety is concerned, it is my firm opinion that an adequate air force is the best peace insurance policy that this country can obtain. "Aircraft as weapons of war fare yearly become more swift, more powerful, more destructive; but it Is in aircraft aa agents of commerce, carrying the1 world's goods and transporting the peo ples of one community to another, that the deeper significance lies. Lower Premiums : "Inevitably the time will come ihen the life insurance companies 11 be willing to grant insurance at regular premiums on the lives of travelers by air and the operat ors of aircraft. Thia would greatly aid the development of air trans portation and I hope that this as sociation will give careful consid eration to such an important mat ter.

This involved the consideration of many factors, among them the Improvement of the equipment, laying out and marking air routes and the creation of proper facili ties along them. With landing fields at proper intervals, many of the risks of flying would be elim inated. - i ' -.
