An organized war is being waged UNLESS YOU PASS TEST OF SCIENCE against tuberculosis throughout the civilized world Much has been spoken and written on the subject. It is not the purpose of this campaign to frighten the people. Instead, it brings assurance and hope. The disease can be conquered as soon as the people generally Join in this campaign. Not much consideration lias been given to this subject in Utah because The musical registering mechanism A ihe semicircular of the ear. canals. K The organ of corll. C The cortian cells. has at last standardized the It has minutely analyzed all the facts that go toward the making of a perfect tone such as Caruso or Eames delights with and thereby gains much money. The new standardization can determine in an hour whether any person really has any chance to become a great opera singer and tell it absolutely, finally and definitely. But It has another purpose. Just as there are mute inglorious Miltons, so, without doubt, there are girls and boys with all the possibilities of the greatest stars of grand opera locked in their throats. The new scientific method of determining the quality of voices will serve to bring out these musical wonders of the future. A singer, to put it as briefly as possible, has to produce a perfect tone. Any person who can produce and control a series of perfect tones may make Migreat grand opera singer. "Science has discovered the production of these tones is fixed absolutely by nine processes. x These nine links, if perfect, make the p?MR ojger. s Jhe The first of these accurate perception by the eye of the note that is the symbol of the tone to be produced. The' second link is the carrying of the note by the optic nerve and its receipt by the sight center in the cortex of the brain. It exists there as "a visual image. From this sight center g it has to pass to the center of the brain for necessary communication to the throat. But in its transformation from the visual image to the sound stimulus it has to pass through what are called memory centers. In other words, it would do the singer no good whatever simply to perceive the note. The note is nothing but a symbol of the sound. And here the memory must be called into play because the look of the note must be changed into the sound of the note, and nothing can, of course, do this but memory of what the symbol means in terms of sound. These are the third and fourth links in the chain. From the sound center the impulse to reproduce it travels down to the vocal chords and the muscles controlling them. These factors must be not only perfectly adapted to produce the sound, but the Impulse between the sound center, No. 5, and the throat, No. 6, must be absolutely true. If it is not, the note that has beep seen, accurately perceived and accurately transmitted to the sound center will not be at all the same note when it issues from the throat. It is here that so many singers fail. At the same time, the other factors in voice production the lips, tongue and so on, No. 7 are brought into play. The note is then emitted. The singer must know that he or she has emitted exactly the right note in its accurate pitch. The sound travels back to the ear, is carried by the car to the auditory centers of the brain. This is the checking up. The ninth link is the perception of rhythm, or what musicians call "time. Time is the harmonious? intervals between notes. This faculty is controlled by the semicircular canals in the ear, which also control equilibrium. When musical notes are read and the image transmitted by the process just described into sound an impulse also goes from the nerves of the semicircular canal up to the sound center, where it arrives simultaneously with the image of the note from the sound center. Both tonal and time impulses then go along the nerves to the vocal chords. It Is, indeed, just like sending two messages at once over the same telegraph wire. This is, in a nutshell, the actual mechanism of what makes the voice of a grand opera singer. SCIENCE voice. nrhnks Me second-emittin- The canals that control rqulllb-roiu- n and rhythmic conccpllon.

It makes no difference what your actual age is, you have what is now known as a mental age somewhere between 6 months and 25 years or thereabouts. Among school children it has long been noticed that some, much older than others in point of years, were a good distance behind them mentally. The idea was evolved that if children, imbeciles and criminals could be given simple tests to determine exactly how far advanced they were mentally a good deal of trouble could be saved in children by placing them In the proper grade at school, in imbeciles to determine exactly what would be best for their welfare, and in criminals to determine the responsibility in a moral way for their crimes.. Thus, if a criminal were found to be only 8 years old mentally, then the proper way to treat him, no matter what hi actual age happened to be. wAuld be the way a boy 8 years of age committing the saiye crime would be treated. jj( j Tests applicable to different normal ages were worked out by patient psychologists and others. Binet has a good many tests that have been modified by experience into what are known generally as the Binet tests. They run all the way from recognizing a hand waved In front of the eyes for a tiny infant to remembering sequences of numbers and describing the various articles seen in a picture but for a moment, for older ones. It is the endeavor of some humane societies to have a law passed to test all criminals, and that, if found of small mental age, they shall not be punished in the ordinary way. It has also been suggested that our own civil service use these tests instead of the oftentimes absurd examinations now -- used. of the comparative small amount of tuberculosis whi(h exists here. But unless vee bestir ourselves we may soon awake to the knowledge that other states, by giving recogriiation to the problem, have passed us In the race, Moreover, we are, by our indifference, permitting the waste of valuable lives. Men and women are dying from tuberculosis all about us. One death from tuberculosis occurs in our state about ectry second day. And the most of these are residents and not transients. The prevention of tuberculosis requires merely the careful observance of simple rules of health and sanitation. The person who takes proper care of his own body and insists that those alout him observe the same rules, is comparatively safe no matter how often he may be brought into contact The careful conwith the disease! sumptive is not a source of danger to others. The cure of tuberculosis is neither difficult nor expensive if begun In time. Treatment in a sanitarium is Usually best and perhaps the state Should provide such an institution. But the cure can be successfully taken at home. The Utah Public Health association, 120 J3. First South street. Salt Lake City, will send instructions for the prevention and cure of tuberculosis to any who will ask for them. WOULD END FOUNDATION. Albany, N. Y., March 30. Bills havo been introduced in the state assembly and senate to repeal the charter of the Rockefeller foundation. The measure, its sponsors said, is the culmination of futile attempts to obtain an official Investigation of the Rockefeller institution. It is proposed by the authors of the bills to have a public discussion at a legislative hearing. The foundation secured a charter from this state after the congress of the United States refused to charter it. LAUNDRY WORKERS WIN STRIKE. Fresno, Cal., March 30. The Laundry Workers union has won its strike against the Fresno steam laundry which broke an agreement two years ago. Union officials state that the organization has won a complete victory and all employees will join the union. The struck plant was picketed almost continuously during the strike, despite police interference and the arrest of pickets. HUTTON WORKERS LOSE FINGERS. Poughkeepsie, N. Y., March 30.

The strikers were unorganized when ihey asked for an increase of i cent a gross. They have since organized and now demand recognition of their union. PACKERS DEPEND ON NEGROES, Chicago, March 30. It is stated that the large influx of southern negroes to this city is caused by the offer of stockyards interests to guarantee lodging and food for one week to the negroes, who are replacing European immigration. It is predicted that Chicagos colored population will have Increased by 100,000 before the first of April, and that already the new ar rivals are living six In a room, PROFITS OF 52,2(17,000. Philadelphia, March 30. Last year the Pennsylvania railroad cleaned up a profit of $52,276,000, a gain of $9,851,-00- 0 over the year 1915. This years profits is divided into sinking funds, reserve funds, profit and loss funds and other funds so that the actual amount earned, according to the railroad's bookkeefing system, is a mere 5$ per cent on the investment. President Rea believes this is insufficient, and says the necessity for higher rates is daily becoming evident. Tube culois Consumption is tuberculosis of the lungs, the most common form of tuberculosis. There are several facts about tuberculosis which every person should know for his own safety and the protection of his family. Tuberculosis is the most destructive of all human diseases. It kills 160,000 persons each year in the United States. It costs ilie United States over five hundred millions dollars a year in loss of life and labor. Tuberculosis may attack any person, anywhere, unless proper precautions are taken. Our climate is no guarantee against infection, although it makes protection easier. Tuberculosis can be prevented. It is not necessary for any one to contract the disease. Doctors and nurses in tuberculosis sanitariums never become consumptives. Tuberculosis can be cured if the disease is discovered soon enough and TOM SHEE BIN 125 W. First South St. . |
