S. Public Health Service announced that it had completed arrangements to expand the medical aid service to American seamen byprescribing by Eadio for any sailor -who might be taken ill at sea and to make application for aid. The range of diseases and mishaps for which aid has been envoked during the first year has been amazing. The list includes many of the common ailments. Many of the diagnoses were made on board ship because sailors are resourceful in meeting emergencies. When the patient grows better and the captain's apprehension is relieved the case usually drops from observation. Weeks afterwards, perhaps, the interested hospital receives direct information as to what occurred later. All in all. Eadio has been pushing ahead in lines little known to those who just listen in for entertainment. High School Instruction by Air Possibilities Suggested as a Result of Experiment WHAT are the possibilities of the Radio in school teaching? Is it going to be feasible to select the best, teachers and have them broadcast their instruction throughout the city and country? We have correspondent courses of all kinds and as impersonal as they are, since they lack contact with the instructor, they are very successful and are being extended. A Radio course now comes within the realm of a possibility. No doubt high school examinations will be the first thing to be broadcast. It will give thousands of students the benefit of a single lecture. Just picture the superintendent of the future sitting at his office desk listening in upon the recitations or tests. Recently as an experiment a test was made in a high school where the instructor broadcast his lesson from a broadcasting station to the class room. The officials at the Board of Education were listening in all the time. The experiment was a success. Standardization Needed Efficiency and Appearance Should be Considered THE time has arrived to take stock again and to ascertain what standards are good, what standards are unsatisfactory, and what additional ones will be required to bring Radio up to date. Where potent reasons stand in the way of standardization it is well to consider the desirability of making such concessions on the part of the patent owners as may be necessary to the mutual advantage of the public, the manufacturer, and the military. It is not necessary that the various manufacturers approve a standard in efficiency and appearance of equipment, or improvements to aid in salesmanship, but it is highly desirable that standardization be required as regards interehangeability of accessories and moving parts to a certain degree, and above all that a standard of quality be adopted so that the service will not be a laughing stock to the detriment of the trade and the interest of the nation. Summer Reception Slight Changes Are Needed for Summer Outfits ALL that is said about static does not dampen the ardor for the out-of-door enthusiast who has become a Radiophan during the past winter. Indications of an active summer with the ether waves are quite evident. Information gleaned from last summer's operation of sets then available has been used to devise outfits that are far ahead of the 1922 model in scope and efficiency. There will be a greater number of portable sets with super-regenerative characteristics. In this class fall the Armstrong and the Flewelling. These sets are compact, they admit of a certain amount of rough handling, and they do receive if properly* assembled and tuned up. Furthermore, they operate on a small collapsible loop with or without ground or with neither antenna or ground. Such sets are ideal for the hobo vacationer. Another change will be noted in the sets arranged for the permanent camp. While multi-stage amplifiers will magnify the music to an amount loud enough for dancing it is probable that these camp sets will be equipped with more phones and fewer loud speakers. Audio frequency amplifies the stray sounds more than the desired sounds, hence for purest tones the set using phones and less amplification will be preferred. RADIO INDI-GEST LEM STEBBINS SWOONS AS HE TUNES IN RADIOKNUPS EPISTLE BULLETIN As this issue goes to press Mr. Stebbins has just regained consciousness and has been heard to murmur, "I'll bet he was kiddin.' " By Pisces Parvum Squedunk, Minn. — Lem Stebbins, inventor, agriculturist, postmaster and local constable, is now confined at the local Quick Service (Veterinary) Hospital suffering from a severe attack of brain fever complicated with static. Mr. Stebbins was found on the steps of the post office last Monday morning when Judge Tibbitts called for his mail. A letter, was found clasped in his right hand and it was necessary to amputate three fingers to remove it. This letter which is believed to be the cause of the entire trouble was as follows: CENTRAL HOSPITAL FOR HARMLESS INSANE Sophopolis, Ind., 456, Padded Lane. Mr. Stebbins: It is with great pleasure that I take this method of letting you know that I am a thorough convert to the use of your hook-up. I rigged it up last night in my quarters and had hardly had it in operation for over five minutes until I got supper, in addition I got several other things which space and modesty forbids me to mention. Yours radiofrantically, Sliphen Burst. The Stebbins' Sooper Degenerative EM-IO BOOKS Key to Parts and Connections MS-1, Marcelled coil; JIS-2, Waterwave coil; 3, Nothing; 4 and 5, Connections to 110 or 1% volt D. C. generator that has A.

(Due to Lem, Stebbins' touch of static we have to disappoint you by only running Vie drawing of his circuit. — Indi.J QUESTIONS AND ANSWERS Dear Indigest: I am still in the crystal set category but ankshus to learn and seeing the letter from Alagonquin Tonsils III, in No. 3 Vol. 5, am deeply interested. Will you pleese advize if it is necessary to use a gas pipe antenna in order to receive the illicit licore from the American Rum Running League? Also where should I attach a fauset in the thing? Would it be O. K. to shunt a spigut across the phones, or does this go in the ground pipe? — Malt St., St. Louis. A — We are at present experimenting but have not tuned in a thing. We don't think they are broadcasting but have heard rumor they intend to observe dry night Mondays. As to hook-up would suggest a bung starter (can be obtained from any local antique store) in place of the tickler coil. Dear Indigest: — I would like to ask one question of your Q. & A. department. I have made a crystal set of the resistance tuned type also adding the Flewelling principle but I can not get my crystal to oscillate in the proper manner. Could you tell me my trouble. Tours truly, — Radio Bunk. A. — We recommend you try the Stebbins Sooper Degenerative. Shake well before using. Hen, You Move Us to Tears Sir: This is to compliment you on your most excellent column, and your removal of the rest of the paper one column to the right of you. In the words of Henry Ford, "Sic Semper Tyranus, Nox Vomica, Acetanilide, FOB Detroit." Were it possible for you to put aside your humble modesty for one moment and publish my effusion, I would be excrutiatingly flattered by having my contribution accepted for the first time out of forty-two attempts. — Henry the Ninth. We Threw Ours Away the Night of Pagliacci Dear Sir — Hurrah, Hurrah! They've gone an' did it themselves. We thot for a long time we would have to do it. Then we decided we would attempt pacific persuasion to tell them to do it. Finally we decided we would have to throw our set away 'cause they wouldn't do it, and now— THEY'VE DID IT! Hurrah! What's that? You don't know? The Am. Sy. of So-Called Authors, etc., have took jazz off the air. Wheeee! — Opery Oriville. Al's Versatile — He Can Draw 'Em Any Old Way Dear Indigest: In Al Brown's cartoon, page 10, May 5, I see the bird has on a black vest in the first picture. In the third picture it is striped and in the last it is GRAY. Canyu beat it? — Voice of the West.

West of Pacific) A Few New Sweet Tunes for His Ears Condensed By DIELECTRIC If the broadcasters adhere to the new schedule provided to eliminate much of the interference that has almost ruined Eadio entertaining we should be able to pick and choose from among the many stations sending out varied programs. The results of the recent conference bid fair to boost broadcasting to a new high level and to encourage those hesitant ones to invest in a receiving set. DX fans will benefit greatly by the new ruling. The popular movie star "Dug" Fairbanks gave permission to Station EPO in San Francisco to broadcast a complete "Robin Hood" program. "Dug" owns the rights to this play and evidently was unafraid of reducing the gate receipts by so doing. WJZ has on several occasions been used to broadcast acts of plays direct from the theaters and so far as I am able to learn the attendance at these houses was subsequently as large, if not larger, than before listeners in were invited. We called attention to the use of Radio in detecting latent power of hearing in those supposedly mutes, and now your attention is called to the remarkable results obtained by Dr. Winslow, a New York specialist, who is accomplishing great things with the aid of Radio in restoring hearing to the partially deaf. He hopes to be able to put aside his surgical instruments and effect cures with Radio alone. More and more is the practical phase of this science emphasized. The experiment made from station WGR in Buffalo, N. Y., whereby an airplane was directed by broadcast instructions points to a new field for using receiving sets. It proves the practical asset Radiophony may be to those engaged in flying either for pleasure or profit. Upon reaching rather high altitudes the reception was poor, but this feature is being investigated by Radio experts. Advice may be given as to location, landing conditions, etc., which would be quite a help. We in this country have been enjoying our Radio concerts while speeding along in railway trains and the novelty of the thing has worn off to some extent. In Canada, however, the first such experience was had quite recently when the WinnipegVancouver train reported hearing concerts from several States of the Union besides Canadian stations. The Canadian Pacific railway company has the honor of first successfully receiving broadcasting on board its express train. Radio has been made a part of hospital equipment in several instances. One of the latest to be recorded is that at the Fordham Hospital in New York City. A man was brought there for an operation which permitted of administering a local anaesthetic. While the four surgeons were engrossed in their work, the patient was noticeably enjoying some jokes that came through the headset provided for his amusement. Both the operation and the Radio reception were entirely successful. It is evident that the proposal to install receiving sets in hospitals for the entertainment of the patients, and in quarters occupied by ex-service men, is receiving increased attention. The men who. fought in the World War and are now in the Boise Barracks are enjoying the use of a five hundred dollar set presented to them by the War Mothers of Idaho. Better follow suit, if you have not already done so. You will be more than repaid by the genuine appreciation shown by these men. Another huge transmitting plant is in course of construction near Miami, Fla., which it is estimated will be the second largest in the United States. It is beingbuilt by the Tropical Radio Telegraph Company for the purpose of handling South American, Central American and West Indian business at a cost of about two hundred thousand, dollars. Not so long ago there were sceptics who scoffed at the idea of Radio being used extensively for commercial purposes. How about ti BAUfflVt
