This possibly is an explanation | of the fact that the movies are begin- ning to pick up talent from the radio ranx My friend, the actor, told me of an- | | other actor—of the legitimate siage— | who was all_but dumb and helpless | when he tried to read his lines before the sound camera at a Hollywood studio. | It was as if the audience, which he | lways had faced, had constituted the eturn in an eleciric circuit.

His company has 1,000 drivers, travel- ing a combined total of 100,000 miles each day. The statistician figured from records on the subject that, attracting one motorist, one pedestrian, and im- pressing one of his passengers to the extent of taking one trip, by courteous driving each driver will increase his passenger list by $4,000 a year, making & total of $4,000,000 for the 1,000 drivers. Edward Yaroshek, who drives a bus in the South, was recently pronounced the world’s champion safety driver by the Atlanta Safety Council. He has been driving highway coaches for eight years at an average of 60,000 miles yearly. His only mishap was in bending a fen- der on a car which was parked, for which his company paid $5.65 in claims. Several other drivers had an entirely clear record, but the huge mileage driven by Yaroshek was equal to 20 times around the world, and he was selected as champion. SLOW-BURNING OIL DECREASES CARBON Method of Lubricating Combustion Chamber of Engine Is Tested. ‘Tests over a period of time under actual working conditions have proved that a small quantity of slow-burning non-carbonizing oil introduced into the combustion chamber of an internal- | combustion engine tends to reduce the accumulation of hard deposits of carbon and at the same time make it possible for a small quantity of oil to reach the extreme top of the combusion cham- ber walls, the valves and the valve guides, said Hugh Swartz at a recent meeting, in Seattle, Wash., of the Northwest section of the Society of | Automative Engineers. | Describing a new method of engine | lubrication, he said that the device for accomplishing these results automatical- ly controls the flow of oil from the lubricator by means of a vacuum regu- | lator incorporated in the line leading ! from the inlet manifold to the dash control and adjusted to admit air when- ever the v m set up in the line| exceeds 2 inches of mercury. From 115 to 2 inches of vacuum furnishes enough | energy to maintain a constant flow of | oil. ‘When the vacuum exceeds this, a thin copper disc on the regulator is automatically depressed sufficiently to admit enough air to restore the vacuum | tc 2 inches of mercury and so main- tain a constant oil flow to the oil-cun-; trol valve in the dash. Regardless of the varying speeds of the engine, this constant vacuum gives | a fixed and constant supply of oil to| deliver to the inlet manifold, he said. ‘When the engine is generating less than | the predetermined vacuum, the oil| ceases to flow. but instantly recom- | mences when the 2 inches of repres- sion is re-established. Thief Jailed and Sentenced 25 Minutes After Crime, | RABAT, Morocco, May 11 (P).— French justice, if slow at home, is | rapid enough in its protectorate of | Moroceo. An Arab caught in the act of robbing &t Morocco City was arrested haled be- | fore the dis t ma rate, awarded six_months' imprisonment and taken straight off to jail. The elapsed time between commission of the misdeameanor and the incar- ceration of the culprit was exactly 25 minutes. Bombay Fan Hears Inauguration.

This, my friend explained, was a_common occurrence, even with | experienced and competent actors. In director dug_out of some old properties a big cyclorama, showing a huge crowd, and placed it in | The psycholog- | ical effect of this was just sufficient | to get the actor off his dead center, or | —t0 use_another figure—to prime the | pump. Words and gestures began to flow and he made a passable perform- ance. In later appearances he became | a dependable self-starter. but he never | got over the curious inertia and help- lessness which come from the lack of an audience. New School of Artistry Seen. 1 Even Demosthenes had to have the | waves to talk to and I don't think the public in general realizes that a new school of artistry has been built up in adapting the human voice and person- | ality to the various mechanical sound | rigs of the last 40 years. In my youth | I remember hearing older persons say | they had difficulty in talking through | a telephone—that they felt a sort of a | panic, and had aifficulty in fetching | up words. It was the same way witn | the phonograph. Many artists have | told me that the hardest ordeal of their | lives was to speak or sing for disc recording. Television is on the way and scignce is more or less fusing the radio, talking picture and phonograph. There will be | more and more mechanization and the | ability to speak or act before a ruthless | little diaphragm, in a cold, white light, | will become an increasingly specialized | art. In some ways I think that this generation of pioneers in such artistry | is just in the beginning. Curiously enough, some of the quick- | est learners are second-rate performers | later on. In radio broadcasting, as ap- plied to announcers and artists, the best of the profession are those who have to fight the microphone to the end. Here is the point: A person who snaps in too casily gets to be part of the mechanism instead of a human personality, inci- dentally being amplified by a mechan- ical process. He falls into a rote habit of speaking and where it is necessary for him to improvise, as in broadcasting some political or sporting event, he is sure to fall back upon worn and trite expressions. The trouble is that the machine has conquered him and made him a part of it. It is as if his mind and voice were geared with cogwheels. Relaxation is Stressed. ‘The better artists, I have observed, are always resistant to this tendency and although they may speak with less ease and fluency than the others, they somehow manage to get through the microphone essential qualities of pen- sonality which vastly humanize the sound in the loud speaker. Of course, I do not actually mean that one should “fight the microphone.” Any experi- enced person, coaching a beginner, will tell him, first of all, to relax, and not to be afraid of the microphone. My point is that one should face the microphone with the illusion that he is facing a vast audience and that if he has any real artistry in his make-up he will find the cold little disc more disturbing to that illusion than in the case of one who is less of a person and less of an artist. Both talkie actors and radio perform- ers agree that there is a tendency GRADED TIP SYSTEM . FOR ITALIAN HOTELS Gifts to Employes Forbidden, but Amount Held Due Is Assessed in Guest’s Bill. ROME (#).—Under a new graded tip- ping system some Italian hotel em- ployes are collecting higher extras than they did when gratuities depended upon the bswu of mind of the departing guest. The new regulations abolish tipping. as such, bul compel hotel and boarding house keepers to add 10 to 15 per cent to the bills for room and board. This money is divided between the “visible” and “invisible” servitors, the former getting 88 per cent while the latter— working in kitchens and other.hidden departments of the hostelries—receive 12 per cent. ‘Then the share of each class is di- vided according to & system of “points” | for each job. In one establishment the total for 10 days was $2,000 and the head waiter had 20 “points” worth $5 each, making his “extras” amount to $10 a day. An ordinary, with 9 points, got $4.50 a day in addition to his small | salary. The system was evolved by a trade agreement between the hotel workers® union and the hotel keepers' associa- | tion. All establishments must post no- tices in four languages that tipping is forbidden. GERMAN SCIENTIST COMING TO AMERICA | Dr. Meissner, Radio Expert, to At- tend Engineers’ Institute in U. 8. Germany's leading radio scientist is coming to America to attend the 1929 convention of the Institute of Radio Engineers. Dr. Alexander Meissner, vice president of the institute, will be here this week to take a prominent part in the gath- ering. He has been a member since 1914.

It is pretty hard, for instance, to get much indi- viduality or fire into a reading of a FEWER LIGENSES GRANTED BY BOART !

If there is much of this to do, the reader will inevitably get into a state where he is hooked up so closely with the apparatus that no one can tell where the man ends and the machinery begins. Radio, of course, must be carefully safeguarded as to what is broadcast, but I am inclined to think that the out- standing broadcasters of the future will be men so informed and so assured in taste and intelligence that they will serve exactly as skilled masters of cere- monies—speaking extemporaneously and adanting their discourse lightly and easily to the occasion. It will be this ascendency of personality over the “robot” suggestion of mechanical speech which will bring radio. telephone and sound pictures to their fullest and bes artistic success.

Although the “standing room only"” | sign has been hung out for some time the petitions of prospective broadcasters arrive at the rate of 6 to 12 a wes Nearly all are from persons desiring to operate small stations serving local audlences, and a big majority come from localities where the broadcasting uota already has been filled. On the six channels reserved for the low power, local transmitters there are at present 243 stations, and in many sections reception is reported to be | extremely poor owing to heterodynes. Even if the quota under the equal allocation law were not exceeded. the addition of stations in these regions would serve only to increase inter- ference, engineers of the commissiop say. ‘The commfssion has been permitting the establishment of some new stations in remote areas where broadcasting facilities are comparatively inadequate. | There are sections of the geographi- cally large fifth zone, comprising the Rocky Mountain and Pacific Coast States, where the addition of many small stations would not cause serious intcrference with other stations oper- ating on the same wave lengths. Nevada has only one station, Wyo- ming has two, Utah three, New Mexico three and Arizona five. There are two obstacles, however, to a large increase broadcasters in that region. One is that the equal allocation law is based on population rather than territorial size, and the other is the lack of applications due to the belief that the venture would not be a financial success in a sparsely settled area.
