Let us stick to the hook-ups that get the most of Radio impulses to the receiver rather than urging or even suggesting something that is far inferior in performance under slightly unfavorable conditions. Hook-ups, diagammatically, at least, are the cheapest part of the set and the parts required for a two-eireuit hook-up are little more than that for a single-circuit set, all things considered. It is quite necessary to guard against capacity effect in the single circuit, much more than in the two-circuit set, therefore the former is much harder to handle, and there is more internal and external capacity effects that are going to interfere and selectivity is not, it is generally conceded, as easily obtained as with the two-circuit set. There is rarely a week free from complaint from single circuit users about interference. The logical means to an end is to build a two-circuit set or if you have a single circuit change to a two-circuit. World's News by Air Great Demand for Information Is Now Supplied DEMAND for information is being satisfied by Eadio. That this demand is greater than it has ever been in the history of mankind is attested to by librarians, who point to the large number of scientific works being read today. It is part of the great progress made in scientific development in the last quarter century. Eadio has not been in the least progressive in this development. In fact, with the development of Eadio, all other sciences are being aided. For Eadio is being used as a means by which knowledge of the other sciences is being spread. Tune m on any broadcasting station and you will just as likely hear a lecture on the fundamental principles of the Einstein theory as you will on the latest developments in. the cure of cancer. Universities throughout the United States have enrolled their faculties toward the dissemination of information under their auspices. Eegular courses in certain subjects are being broadcast, and more are being planned. Concerts are giving Eadio listeners a wider knowledge and greateT appreciation of music. Plays, classic and modern, also help advance the education of the public by Eadio. Health lectures are regular events for Badiophans. So are lectures on child care, and on various other topics now and then are broadcasted. Growth of the Industry Almost Three Million Fans Now Have Sets OLD established manufacturers of Eadio apparatus of a year ago were wondering how they would dispose of their stock. Many dealers were just making a bare living at selling Eadio apparatus. Just about three hundred thousand Eadio amateurs scattered throughout the United States constituted the field for sales of Eadio goods and apparatus. Since then a great change has taken place. Old apparatus, instruments manufactured under patents fifteen years old, ordinary double slide coil crystal sets were becoming immediately popular. Now there aTe more than six hundred incorporated manufacturers of Eadio apparatus in the United States. It is impossible to estimate the number of dealers. There are almost three million fans who have bought and installed Eadio receiving sets. These sets receive music and other broadcast matter from some five hundred or more broadcasting stations located in every state in the Union. Every state but one has one or more stations, and some have as many as twenty. With the establishment of more solid Eadio regulations, with the advent of fair competition and intelligent manufacture of Radio apparatus of good design Eadio will still grow. RADIO INDI-GEST Here we arc in our new' home! How do you like us over in the center column? That is what we want to know. Do you Radioknuts want a whole column of Indigest or do you like it better at we were?

Personally we like it better here but ice hare it up to you, so write in and tell us what you think of it. — Indi. INDIGEST SCOOPS WORLD ON STEBBINS' DEGENERATIVE SET BULLETIN Squedunk, Minn. — In an interview with Indigest Stebbins says, "Gol darn, if it ain't the dad blamest shame the way most inventors hold onto they circuits. I intend to give the Sooper Degenerative to everybuddy that's got the nerve to use it." By Slatherty Simpson Armstrong, Logwood and Flewelling — and now comes Stebbins. The Radio Indigest has scooped the Radio world on one of the most deficient sets ever invented. It is with pride that we announce the series of articles "written exclusive for INDIGEST" by Lem Stebbins, inventor, postmaster, and constabule. of Squedunk, Minn., on his latest circuit "The Stebbins Souper Degenerative Set." Article I begins next issue with Mr. Stebbin's exclusive drawing of the set in INDIGEST. Watch for it! A Radio Shock One night, as the storm beat and blustered, I sat at my Radio set. And listened to lectures and concerts and talks. By guys I never had met. I had just heard a concert that came From Los Angeles over the wire; It was followed a few monments after, By a clergyman preaching "Hell Fire." I followed as closely as may be, But my senses would lag and shirk, And I drowsed as the clergyman ended, And then came to with a jerk. He had preached on sinners and sinning, And I felt like a blooming toff ; But he ended his lecture and then inquired, "How do you shut the d — n thing off.-'" —J. FOSTER MOORE. QUESTIONS and ANSWERS Q. & A. Department, Indigest — Dear Sir: Can you tell me whether I can buy, and who makes, the super-ultra panel stretcher? I have a 7x18 panel that I would like to stretch to a 10x20. Thank you horribly. — Lillian G. A. — It is against the policy of Indigest to advertise any Radioknut apparatus. Sorry. However you might try to borrow one from Al Brown he has one that he stretches his cartoons with. Q. & A. Deparment, Indigest, Dear Sir; Will you kindly tell me what are the present circulation figures of your asteamed paper Thanks for the answer, — Jimsie. A — At present we are the leading paper in the field and are now running 000,000,000,07 more copies than our nearest competitor, the radio digest. READERS' VIEWS We Shall Ask Arthur— We Shall Indi: Hah, Hah! Shhh! Not so loud. In looking over Mr. Mohaupt's article last issue of radio digest (April 28), page 11, I noted the title "Storage Batteries and Their Care," and then whatcha think? In the first column I note a cut of a glass arrangement with a rubber nipple attached. Ha, Hah! Very clever of that fellow Mohaupt. Yes, yes. Is he married? -WOR Listener In. EDITORIALS The music publishers of a certain society demand pay for their copyrighted material. Is this a mercinary motive or fair? — We think so too. INDIGEST has taken its stand and we feel that we are founded on the sound principles of Being Right. WE WILL NOT publish any copyrighted music of the authors, composers and music pub. assn. in our unfilched column, as we are founded on non -money-making principles and do not believe in grasping extortion (unless the assn. should wish at any time to pay us for doing the same). Until such time we ask that the Radioknuts, and all INDIGEST followers, stand by us in our just and honest views and refrain from whistling any and all songs published by the assn. Their latest number is "My Mammie Was Born in Ireland and Lives in Dixie Land — So That's Why I'm the Sheik of Schenectady." DON'T sing or whistle it! ! I! INDIGEST KINKS? SEND A DOLLAR— THERE are many little Indigest kinks worked out in the home that would hamper your fellow Radioknut and cause him much worry. Indigest is very much interested in securing such material and is willing to accept a dollar for each kink printed. Send a stamped envelope so rejected copy may be returned. Under no circumstances will the dollar be sent back. INDIGEST KINKS DEPARTMENT Deer Endi — i bot a radeeo set and my muther-in law wuz alius trying to listen in, sew i hooked the hed set to her dome during a thunder storm and now the old dame aint botherin me no more. This kink will wurk providing youre luky but you stand to loose a good set by having same burnt out. Enclose pleze find my dollur. — eZra HechT. Looking Ahead Indigest has scooped the world on the Stebbin's Sooper Degenerative Circuit. It is with pride that we announce the series of articles, to begin in INDIGEST, written exclusively for INDIGEST by the inventor. Reserve your copy of INDIGEST at your favorite news-dealer — 10c. GEE! THIS ISA SWELLEVENING FOR AWALK RADIO SUPPLIES! WONDER WHATSON THE AIR. TO-NITE? GOSH? BET I HISSED SOME GOOD PROGRAMS Condensed By DIELECTRIC One 's mental condition at the time of illness Teally has much to do with the rapadity of recovery. That may be according to Coue ; if it is, don 't belittle it on that account. A young lady is doing very well in the Montreal General Hospital in spite of having suffered a broken back and this is largely due to being able to listen in to concerts and other entertaining features over the Eadio. The usual procedure of broadcasting from a college was reversed when the authorities at Haverford College, Pa., used their receiving set a short time ago to bring a lecture to the student body. Lord Robert Cecil's lecture delivered in Philadelphia was broadcast through Station WFT and it was desired to have the students take notes on it. This is likely the first time that a class has been addressed by Eadio with the "prof" in another town. A church without a pastor need not necessarily be a church without preaching. If the members will purchase a receiving set and amplifier they may utilize the services of a minister supported by others. The Belmont Methodist Episcopal Church, of Belmont, Mass., installed just these things and when their regular pastor was away they carried on the services by employing the aid of Eadio. Instead of closing a weak church it might be made to thrive by this means. When Station WEAF sent out the songs of the college glee club contesting at Carnegie Hall, New York, we were asked to pass upon the merits of each and pick the winner. The singing by each of these clubs displayed careful training and excellent ensemble. Dartmouth received the first prize, Princeton second and Yale third. I'm glad the decision did not rest with me, because I was lost in the beauty of their combined voices. Eadio is fast becoming an economic asset to various fields of endeavor. I shall mention only one instance at this time. Where a large force of foresters were formerly needed to patrol a certain district in the neighborhood of Spokane that work is accomplished by one airplane. Patrolling these one million acres of timberland requires but two and one-half hours daily, whereas the former system required constant attention. The secret of it lies in the fact of the plane being equipped with Eadio. You see Eadio is an economizer, whether so used or in place of six seats at a concert hall. Eadio is one of the best publicity agencies available. The use for this purpose is coming to be more extensively recognized both in this country aud in Canada. There it is being used by the Calgary Board of Trade to reach probable tourists from every State in the Union and every province in Canada. Calgary and its environs will be extolled as exceedingly attractive points to visit with Eadio broadcasting as the medium setting forth this information. CHCGr is being used for this purpose and since it has been heard all over the United States the Canadians are expecting notable results. This is for the pessimist who views Eadiophony as a plaything and of but passing interest. When blizzards and cyclones destroyed means of communicating with adjacent territory by putting the telephone and telegraph lines out of commission, what was done? Why they waited until those lines were repaired. During the recent blizzard in the Middle West, which wrought havoc with the telegraph lines, what was done? Well, KYW got busy with their EADIO transmitting station and relayed whatever news was of importance to receiving sets tuned to their station. Without Eadio this could not have been done, but with it the storm's damage was mitigated.
