For one who seeks reception over short distances of about fifty miles a eet of this kind is more than satisfactory. There are many fans owning multitube receivers who still keep their crystal sets for local reception. The dear natural tones are a pleasant No change from the loud speaker. harm will result If you take a little snooze, for there are no batteries to run down gnd no tubes to turn out. Selectivity Limited. The principal objection to the crystal set Is the lack of selectivity. It lacks the power of the tube receiver to cut one station In and another out. If necessary tuning devices are used that are essential to make a crystal set selective, the resistance created seriously . Impairs the volume and shortens the range. The energy used In a radio set Is infinitesimally small. If all that is accumulated on the average antenna In a year's time were collected into one charge It would not be It . sufficient to light a flashlight bulb.

There are several methods that may be used to make a crystal set selective. hese are loose coupling of the Junlng inductances, the use of several Variable condensers, or adding a wave-tra- p arrangement Aside from being added expense these methods are not wholly efficient., One result Is obtained through the sacrifice of another. uninsulated If more convenient. The parts necessary to construct the set are as follows: One variometer (should have about 80 turns on both rotor and stator). One .001 variable condenser, about 43 plates. One variable crystal detector. One seven by nine panel. Baseboard, binding posts, screws, wire, etc. .boston Traveler. . Describes Simple fester for Circuit Continuity By F. E. MADDOX I have assembled a very simple test outfit made up from odds and ends around the work shop which helps considerably in determining whether purchased parts and laboratory odds and ends are defective or not. It has also been found useful in testing out radio sets for continuity of circuit, testing fixed and variable condensers for short circuits, Jacks and sockets for loose connections, and transformers for short circuits, open circuits Don't start your engine In the garage with all the doors and windows closed," warns Fred M. Rosseland, chief of the public safety division of the National Safety council. In calling the attention of motorists to the danger of automobile exhaust gases .In unventllated rooms. Although many cases of fatal carbon monoxide asphyxiation occur In private garages every year, especially in northern communities, still the hazard does not receive the attention .It deserves as a menace. Induoes Asphyxiation. "A running motor In a garage 10 by 10 by 20 feet with doors and windows closed will In five minutes produce enough monoxide gas to Induce asphyxiation," says Mr. Rosseland. If the engine continues to run, the mounts steadily toward a rapidly fatal amount. If It la necessary to run a motor for any length of time, take care to see that there Is sufficient ventilation to keep the air clear. The deadly carbon monoxide contained In the exhaust gas creeps upon one and does Its work without warning. The victim falls Insensible before he realizes that anything Is wrong. A slight dizziness Is the only warning. Exercise of a little fore thought In giving the garage sufficient ventilation while the engine is running will eliminate the danger." In case of carbon monoxide asphyxiation from automobile exhaust gases, immediate application of the prone pressure method of resuscitation la Immediately and absolutely necessary. Even a couple of minutes delay after breathing has stopped, may be fatal-- a quarter or half an hoar is almost always fatal. The next step after restoring spontaneous breathing Is to accelerate the elimination of carbon monoxide from the blood. Oarbon monoxide unites with the blood and Left in the displaces the oxygen. blood it attacks the brain with disastrous results to the victim. Extensive experiments carried on jecently by Dr. Ye n dell Henderson, of Yale university, Haggard and A. L. pd Dr g, Prince, showed that the only certain method of displacing the carbon monoxide was through the Inhalation of a mixture of oxygen and carbon dioxide. Most municipal gas companies are now equipped with the apparatus for reviving victims of carbon monoxX! ide poisoning. Preventive Measures. But preventive measures are much more to be desired than the use of resuscitation knowledge in bringing a victim of automobile exhaust gas back to consciousness," says Mr. Rosseland. In this case the open door Is the safeguard. If necessary to run your motor for any length of time within the garage, open doors and windows. Just remember this and pass the same information on to your friends. It may save a life!" Carburetor and Vacuum Tank Need Attention Spare the hammer. It la your worst enemy in the tool kit. Parts that fit, or that come apart, properly, seldom have to be hammered. When you think you have to use the hammer, that Is the time to make up your mind that yon aren't doing the job right, says a writer In an exchange. It's all right to tap a part when It 'wont come free, and when you are dead sure it should. But In that case use a wooden hammer, or strike with the wooden handle of your regular hammer if you havent got the safer kind. One trouble with hammering Is that youre sure to give yourself some new trouble. Youll either bend something or break It. When a shaft or a rod or a pin wont tap out easily there's something holding It, and the first Job Is to look for the snag. ..Heres where an oil can is more useful than the best of hammers, because it gets at the root of the trouble without damaging anything. If oiling fails maybe theres a rough spot somewhere that you could smooth off with a little emery paper or a fine file. A burred spot on a shaft that you are trying to tap out of a bearing will usually get worse If you hammer. There are more ways than ons of removing a part that sticks, and by this I mean that If you can't drive it out In another direction maybe you can free It by taking something else apart. You wont be wasting any time or effort If you find that the trouble is in the part that supports the part you thought was doing the sticking. - But spare the hammer. That's one point I always try to hammer home. England. An extragedy, reviving the question of Justification in the taking of life under special circumstances, occurred in the vicarage of Hungerton, Leicestershire. The vicar. Rev. William Bettison, after celebrating communion, returned to his study, from which shortly came the sound of a shot. The vicars sister, Miss Bettison, who, with her brother and a housekeeper were the only occupants of the vicarage, went to the study and found her brother lying on the floor. A sporting rifle was beside him, and there was a wound In his head. Miss Bettison went to the post office and telephoned a doctor who lived four miles distant. She then returned to the vicarage the study, refusand ing to permit anyone else to Leicester, traordinary come In. A little later another shot was heard inside the study and Miss Bettison came out. I asked him if he would live, and he did not reply, she said. I saw he was dying in agony, so I shot him to put him out of his pain. Miss Bettison was arrested. Later, after an examination, she was declared insane and taken to an asylum. GIRL FOUND DEAD BESIDE HER VIOLIN Manipulate Auto Lights by Knob on Steer Wheel Charms So Music Before Life.

While Helen Quinlln played the violin in her furnished room on the top floor at No. 122 West Seventy-eighth street, other lodgers gathered In the hall and listened. They agreed that Helen, who was twenty-two- , possessed great talent It was unfortunate that she should have to work for a living as stenographer in the offices of a biscuit company. Still, she had been in the city only four months, and perhaps her opportunity would come in time. Helens playing ceased. The hallway audience waited a while and dispersed after agreeing there was a great future in store for her. Next morning Allie Crutcher, ' the maid, was almost overcome by gas when she opened the door of Miss Qulnllns room. The maid called Mrs. Mary Hickey, proprietress, who summoned others. They found Helen dead on her bed, her violin at her side. Gas was pouring from a tube disconnected from a small stove. How it became disconnected is not known. Fete Reformed Criminal on Return to Home Minneapolis. A man who, as a confessed criminal and an undesirable, left Minneapolis 32 years ago by order of the police, recently returned, a convert to Christianity and a leader in welfare and criminal rehabilitation work. He Is John Callahan, superintendent of Hadley Rescue hall, New York, and chaplain of the Tombs prison. Driven from this city In its infant days as a convict, too crooked to tend bar and as a confessed thief, Callahan, on his return, found Minneapolis paying homage to him In almost unprecedented manner. He passed one week here, and was swamped with visits and messages from Minneapolis leading men and women. Callahan spoke before many of the leading local civic, business and church dubs in addition to Innumerable other gatherings. Faith in the Bible, Callahan told his audience, made me good and kept me good. He still carries the same little copy of the New Testament given him the night of his conversion.
