GRAND OPERA Mil iiijlmMm .VKW YORK. MBLf 11B lllllllllllllllllllllHllllllllllll,) nr rTTmrrr SKN FRAVCI5CO Y WIRELESS IKil How the Acting and Singing of Great Artists May Yet Be Seen and Heard Simultaneously in Hundreds of Theatres Throughout America. G RAND opera by wireless Is n possibility of (he near future, according to a prediction matio by II. Gernsbnck. editor of Radio Amateur News, who bases his statement on a ro cent report from Chicago to the effect that grand opera music had been transmitted by wireless telephone for over 100 miles. Scnsitivo micro phones placed on tho stage of the opera house caught the sound waves; tho impulses then being tepped up in the usual manner by nnans of a transformer were then led into an amplifying vacuum tube. Here tho current was impressed upon (ho radio telephone transmitter in successive stages and then sent out over the aerial on top of the opera house. Wireless amateurs all about tho surrounding country were thus able for tho first time to hear grand opera. "Anyone with suitable radio apparatus can listen in' to the mucic without much trouble," declares Mr. Gernsback. "No matter on what wavelength tho music would be rendered, every wireless man would find a way to listen to it without serious inconvenience. "During the next few years it will bo a com mon enough experience for an amateur to pick np his receivers between 8 and 11 o'clock in tho evening and listen not only to the voice of such tars as Caruso, Totrazzini, McCormnck and others, but also to the orchestra music as well, which is picked up by the sensitive transmitters along with tho voice of the stars. The surprising thing 13 that it is not being done now. "The reason probably is duo to the fact that as yet no means has been found to reimburse tho opera companies for allowing everyone to listen in. Whilo of course listening to tho music is not ns satisfying as witnessing the performance in person, still many music enthusiasts would rather stay home listening to the music alone than to witness the performance) itself. To your true, dyed-in-thc-wool opera fiend the performanco is of secondary importance, tho music always com ing first. "Hut we must give a thought to the manage ment, which cannot subsist on an empty opera house if everyone could listen in to the actual rendering of tho opera without paying for the privilege. Needless to say that tho producers would soon find themselves bankrupt. For this reason we cannot expect that grand opera by wireles.i will be an accomplished fact until some means has been found to reimburse the producers, and, a? every wirelc33 man knows, this is very difficult to do." Mr Gernsback suggests as probably the only logical way out of this difficulty fpr a grand opera company would bo to advertise in the news papers, stating that no grand opera via radio would be given unless a certain amount of reve nue were guaranteed by radio subscribers before "radio performances" would be given. This would mean that probably 10 out of 100 radio station?, amateurs and otherwise, would pay monthly or yearly dues to sustain the management, which then would not have to care how many wero listening in. This is the only practical solution. As for technical difficulties, Mr. Gernsback says, there are, of course, none. All that is nec essary for the producing eompany !s to Install a high-class wireless telephone outfit which cn be bought on tho market right now and which Is immcaiatcly available. The rest is up to tho wire less fraternity, which has nothing elso to do but listen in. How this Is done Mr. Gernsback de scribes as follows: 1 At the receiving end, tho futuro up-to-date radio opera enthusiast will, of course, have a first-class receiving outfit, using vacuum tubo am plifiers, and a loud talker such as depicted in tho right half of the accompanying illustration. Then it will bo n simple matter to listen to Caruso himself, though he be a thousand miles distant. Ilis voice will come out loud and distinct nnd tho amateur's family will be enabled to "listen in" to their hearts' content. There is still another novel schemo recently originated by Mr. Gernsback which he also de scribes in Radio Amateur News. The underlying idea is not only to give grand opera by wireless, listen to the music and to the singers only, but actually to see the operatic stars on the screen as well. This is how it can bo readily accomplished by moans which are avail able today, and without the slightest technical difficulty. By way of example, the writer takes the opera "Aida," filmed in its entirety. This may mean a four or five film feature. Tho opera will be filmed just like any other photo-play. The stars, singers, players, tho chorus, or chestra, conductor, etc, are then assembled In a moving picture studio and in front of them is tho usual screen. The opera "Aida," which had been filmed before, in now repeated on the screen whilo the entire cast follows the screen picture closely. Each performer, every star, every member of tho choru3 has his or her own microphone in which he or she sings the regular score, watching closely the film-play as tho action is unreeled on tha screen. The moving picture opera through tho film operator keeps time with tho singers, and GRAND OPERA BY SYNCHRONIZED MOVIES AND RADIO The Grand Opera Stars Will Sing (o the Accompaniment of Their Own Film Opera in New York, While the Identical Opera 13 Shown In Thousands of Moving Picture Theatres All Over the Country at the Same Moment. By Means of Loud Talkers Placed in the Movie Houses, the Voices of the Singers Could Then Re Heard In Theatres All Over the Country. All the Moving Picture Operator Has to Do Is to "Keep Step" with the Incoming Music. the singers themselves must keep exact time with the performanco as it is unrolled on the screen before their eyes. In as much as the identical cast has been filmed, it will not bo difficult for them to keep time with their own performance, as may readily be imagined. In other wonte, says Mr. Gernsback, when a singer sees his own figure appearing on tho scroen ho will know ex actly how and when to sing into tho microphone in front of him. All of the microphones go to the wireless tele phone fetation located in the radio room above, and there are, of course, sensitive microphones In tho studio which pick up the sounds from the orches tra as well. All sounds are then stepped up through tho usual amplifiers and are then led How BIRDS Carry Their FEET When on the WING I T is not surprising that airmen have tried to learn flying from the birds, although thero is one essential difference be tween these .(and all "fly ing creatures) and the air-., plane, in that tho for mer's planes are also their propellers, while in tho latter the pianos are mere ly supports to an object pulled or pushed along by propeller. "There is, however, a time when the conditions o bhd and airplane are the same: that Is. when the bird ceases to flap and tho airplane's englnos stop, when both resort to a gilding motion, held up by tho restslai.co of the air to tholr supporting crxDW ftXTm HEAD OUT WOODPECKER MEAO AhD FEET BOIH OUT GAM MET MCAU lh GULL a quito independent Four Ways Birds "Stow Their Lumber." planes.

A "CRADLE" Used for REPAIRING AUTOMOBILES NOT so very long ago somebody wrote a song about "getting out and getting under." Someone promptly suggested that the song was the result of the extensive automobiling ex perience its author may have had at one time or another when he was confronted by an emergency in which he had to effect repairs to the parts of the mechanism located under tho car. This has always meant scrambling benpnth tho car lying on one's back to work in a very awkward position, with grease and other things falling on one's face and even in one's eyes. This is, appar ently, not to be avoided when repairs of this na ture have to be mado on the road, but when it hap pens in the garage it seems that there should b somo substitute for tho good old game of "get An Automobile in Position in the Cradle That Is Ready to Be out and get under." To be sure, the pit is found in an occasional repair establishment; but this has to go in when the garage is built or its cost is excessive, nnd it is only a haif-wav relief. There would seem to be a wide field for Rome simple apparatus that would enable a workman to get at the under side of the car. Such n device has been invented by L. C. Nicoson of Alexandria, Ind. It is described in tho Scien tific American as consisting sim ply of a cradle into which the car can bo run and in which it can then be tilted to any desired an gle. It is very plain from tho accompanying illustration show ing the outfit in action that in tho last-named respect it is far su perior to nny pit or elevated track. No lunger is it necessary to work above one's head in tink ering with tho bottom of the dis abled car which easily enn bo turned to any convenient anglo and so worked at from tho most advantageous position. If the car is wanted in a horizontal posi tion it can quickly bo so placed with the added convenience that the owner is then able to work at it from above, instead of break ing arms and neck to work from below. The track on which tho cir cular member rolls should be noted, as well as tho chain and sprocket by means of which thi rotation is accomplished. Tho car is run upon tho longitudinal tracks by means of skids or an in clined runway, and is hold in po sitton against tho rolling by chains which pass nbout tho wheels and make them fast to these tracks. "Tho sort of bird that the airplane ought to taka lessons from is tho vul ture," says Mr. Frank Finn, the well known Eng lish ornithologist, in de scribing in the London Graphic tho four different ways that birds "stow their lumber" or carry their feet while flying. "The vulture's life is one con tinual patrol, and a patrol performed with the minimum amount ot tngtne work. You never seo a vulture Happing Ub wings excopt when flying low; once well mounted it Is the most mechanical looking object In nature describing endless circles In thp blue, with rigidly outstretched and motion less wlims. It Is obviously nccopsary that so largo a bird, whose mpal aro few and very far botween, rhould havp evolved some method ot patrolling without expenditure of vital force. "Apropos of bird and alrplano, a question has recently come up as to stowage ot lumbor In flight. Tho foreparts and feet of birds when on tho wing lire simply so much dead weight, and It is Inter esting to note that of tho four posslhlo ways of itoins this awa all aro practised by birds, and that sourers aro to lio found in all four sections. Crows and all their little relatives of tte 'passer ine' group sparrows, swallows, etc. draw their heads back to the shoulders and tuck up their feet In front, and It Is well known that crows can soar quite wWl If thoy like; albatrosne3, gulls and birth of piej draw In tholr heads but stretch out ihpir foot an'i their xoarlng powers are notorious; stork?, cranes, pigeons, ducks, gannets, etc., tlretch out both head and feet, and thp first two Hoar quite well, whilo tho common pigeon may often lie Been to volplane for many yard3. "The fourth possible pose, with head stretched out and feet drawn up, Is very rare, being appar ently con lined to woodpeckers and toucans, and to tho barbcts, which form the link between them." Into the high-power vacuum pliatrons, whicl finally amplify tho original Bound several milliot times. These impulses are then sent out over thi usual aerial located on top of the house and an shot out all over the country instantaneously. Five hundred to one thousand miles away snd for that matter all over the country everj moving picturo house will have been supplier with the identical film at the stated performance it having been announced days ahead that th grand opera "Aida" will be given at such ant! such an hour. Of course, where the distances are large, th hour of rendering tho opera will vary. Thus, foi instance, if Caruso were singing in New York and a performance would start at 8 o'clock in tho evening, New York time, it would start in San Francisco at, 4 o'clock in the evening, as a matineo. duo to the difference of time. In an much as such performances would probably only be held onco u month, people would not mind to inconveniencu themselves duo to slight difference of time. F.very moving picture house will have its re ceiving apparatus with its usual amplifiers and anywhere from six to one dozen loud talkora scattered through the house. Exactly at the stated time the moving picture operator will be gin grinding away tho opera has begun. Simul taneously the distant orchestra will begin play ing, filling the house with music. When the actual performance begins, it will be an easy matter for the operator to keep time with tho incoming music. All he needs to do ii to grind fuster or slower, and in as much as Ca ruso with his performers in New York is watch ing the identical film, the distant operator will have no trouble to have the music keep time with his tilm. If he finds that he runs ahead for onu second, he can readily slow up the next and vica versa. With a little practice it will be easy foi the distant operator to time himself perfectly, thub giving patrons of his house an ideal per formance. From a financial standpoint, Mr. Gernsback say3 that it would be good business for tho oppra company, as well as for tho moving picture houses, both of which would thus derive a new Income running into the hundreds of thousands without hardly any expense whatsoever. He esti mates that a grand opera with an outlay of from 51000 to $3000 could buy its high-power radio telephone outfit, while every livu picture house throughout the country would be able with an ex penditure of less than ?500 to buy its necessary radio telephone equipment and this cost would only be initial, because nothing except burnt-out vacuum tubes need bo replaced and thore Is prac tically no coRt of up-keep. Cultivating CAT-TAILS as a New Source of FOOD WHEN you wero a child did you ever maka torches of the cat-tall plants by soaking them a long time In kerosene? That wai fun but not especially useful. There is a new use for cat-tails which is more practical. It haj recently been discovered thnt tho roots of tho common cat-tail found In swampy soil furnish an excellent Hour much liko wheat or corn flour, about 5500 pounds of which arc said to be yielded from one acre. Food chemists have found, says Life Exten- ion Institute, that this Hour contains overy ele ment .of nourishment found in grain flour. It ia the underground stems that supply the flour and the process of stripping them is not unliko that of peeling potatoes and quito ns easy. Tho starchy portion is then released nnd can bo sifted into a flour which lut3 been mado Into excellent biscuit nnd puddings, in the opinion of bravo pioneers who dared to eat them. "Bravo" they were, because to try nny new thing requires cour. age. Most people would hesitate, feeling, half. afraid to try cat-tail flour biscuits. "It Is only a weed" you are probably saying as you rend this. And yet there is nothijg new in this process of turning weeds into food. Foi 30,000 year? man has gradually been working out agriculture, changing from a creaturo thai searched over rocks and in wootls for all his food to a creature that cultivated food in stationarj places. Long before there was written history ol nny kind man had developed an abundance ot nourishing vegetablo food and ho is constantly adding to the variety of his supply. Potatoes are an American product and won not cultivated in Europo before tho 18th century. Beets ns a source of sugar were not known untii quito recent times. Tomatoes used to bo though' poisonous. Parhups in the near future we shal bo passing fields of cultivated cat-tails waving the breeze and eating cat-tail flour pie crust over meal for desert. Newnpnpor IValnro SrnliM-, 0!0.
