F ' , 1 I Q? 'W' ' Mounting Butterflies When it comes to the transmission of these waves, there is a fairly large amount of experimenting that has been done, but even in this field there is an unlimited amount of work to be performed, as yet, before it will be practical. When the frequency is below one meter, short waves begin to function as heat waves and the reception is no longer useful unless the transmitter and receiver can communicate with each other for making the proper transmitting adjustments, - It is quite certain an entirely new science will be developed by means of these new laws which have important therapeutic values, cancer research, botanical research and many other important developments will take place. The most abstract fiction writer would refuse to predict developments for fear that his predictions might prove too calm. At these extremely high frequencies the difference of a few cycles may form a thing not wanted by the experimenter and cause a disaster. It will take many years of hard research to unravel the many new obstacles that lie before him. The research man will demand a new class of instruments and apparatus, to make possible the proper measurements. All these various .difficulties found are not the kind that stop an experi- menter, for the more difficult the obstacles the faster they will draw the attention of the minds that are delighted in solving problems of this kind.

Neved Ending Wonders It has been predicted that we have not yet lifted the cover of the possibilities of these marvelous frequencis, but it sems certain that all the astonishing projects that radio has presented during the last decade Will be incomparable with those yet unknown and unsolved that shall be unearthed during the next thirty years. In various ways the theory of radio is fairly well known today, but there are unfounded facts that are yet without interpretation. Many gaps occur in the physiological and psychological effects that take place in our modern radio laboratories. The subjects are open for the proper improve- ment to any one who wishes to experiment with them, and there may be some unsurpassed possibilities of utilizing these forces, yet unknown to us for practical' use. ' VV hile experimentations with short waves below five meters are taken into consideration, it should only be attacked! by those not only Well versed in the facts known about radio but in the science of physics as Well. This is an important factor for the reason that ultra short Waves are apt to become injurious when handled by those unacquainted with their effects. For instance, it was found during a laboratory test that on certain fre- quencies short waves could produce fever heat by means of vacuum tube oscillation. In addition when the tube current was turned off the fever quickly subsidedg in other Words, it was found' to be controllable, which means that heating of our homes by radio is possible. It may be found necessary when workingwith low Waves that research men will have to wear special protective clothes and' masks resembling those now used by X-ray and radium workers. ' Eighty-one

SUBJECTS OF INTEREST In our Science Classes, We have the opportunity of choosing some subject in which we are interested and developing it in any way that we wish. Sometimes We arrange exhibits, or give demonstrations to illustrate the topic we have decided upon, but usually we gather information from many sources and write it in the form of a book, drawing pictures or finding illustrations to make our books more interesting and attractive. Among the subject we have chosen to work out have been the following: NATURE STUDY-Bird Life, Butterflies and Their Life Histories, Wild Flowers of California, Insect Enemies to Man, Forestry, Life in the Sea, lVIicroscopic Forms of Plant and Animal Life, Fungi-Their Value to lVIan and the Harm They Do, Termites and How to Control Them, Breeding of Goldfish. lVI1s'1'AL WORK-How to Make Castings of All Kinds. PHYSICS-Communication From the Beginning to the Present Day, Sound Vibrations as Shown by Many Musical Instruments, Time-How and Why We lVIake Our Timepieces and Calendars. CI-ITEIVIISTRY'-'II'1Ol'gZIl'liC and Organic Chemistry. ELECTRICI1'YiAI1 Explanation of the Simples Rules for a Beginner, How We Use Electricity in Our Homes, Wliat We Know About Electricity and Wliat the Future Holds for Us. ARCHAEOLOGY-How the Egyptians Built Their Pyramids, The Mayan People-Their Art, lldathematics, Astronomy and Buildings. TRANSPORTATION-Rocket Planes, The Development of Means of Transportation, A History of Railroads, Boats. AVIATIQN-A History of the Development of Aviation, How a Modern Airport Is Operated. SPEED-Racing Cars and Planes. PLANT FER'r1I.IzERs-A collection of 30 specimens of the newest com- mercial fertilizers, where they come from and how they are made. F IREARIXISLFTOITJ the earliest time to the present, PAl,EON'l'OLOGY-L8 Brea Pits, Fossils and What They Tell Us. Foons-Their Value and How to Prepare Them. CLOTHING-Fabrics, XfVl1CI'C They Come From and How Made. Pmzcrous S'roNEs-Minerals- A Collection of Rocks. RADIO-Higll Frequencies, Short VVaves, Amateur Sending. ASTRONOMY-A Study of the Stars and Planets of the Solar System. EXPERIMENTING IN THE LABORATORY In our science laboratory our teacher directs us in the methods used by scientists. She performs many experiments for us and we are permitted to make many for ourselves. Some of the older boys and girls demonstrate for the younger children. Through the laboratory windows we can keep an eye on our fish pool and see that a proper balance between plant and animal life is kept. VVe study plants and apply our knowledge in the care of our garden. The exeriment illustrated here represents a hot water heating system. The purpose is to demonstrate the method of its working. The materials used are three lengths of glass tubing, two short pieces of glass tubing, three ring-stand clamps, one large ring-stand, one large test- Eighty-three
