new and that have a of startling appearance is a matter of illustration An interest general this fact is presented in the Journal of Heredity by A D Shamel physiologist of the United States Department of Agriculture who describe a pink-fruitlemon These pink lemons are oblong to shape of medium size rough or ridged in texture and have thin rinds The is abundrag is tender and the juice ant but usually lacking somewhat la acidity The lemon have a striped appear ance usually with alternate green and white areas This appearance is corr- -' lated with a ridged condition th ridges being usually green in color while the depressed spaces are whit The very thin rinds and rough appearance of the fruits as well as th relatively low yields of the trees makes this strain of very doubtful commercial value but it is rather widely planted in some citrus growing areas of th Southwest solely for ornamental purposes Last year Mr Shamel noticed a typical variegated lemon among a collection of citrus fruit sport that was presented as a feature of a general exhibit of California fruits Upon examination this variegated lemon was rind found to have a and flesh The- parent tree from which this pink lemon was picked waa located in a small planting of citrus tree in the grounds of tne Winter home of Mr D W Field at Burbank California THE Type to Penetrate Outer Space and Explore the Headens

practical application I E Mouromsteff who waa in charge of the development work done In the laboratories of the Westinghouse Electric and Manufacturing Company points out that the difference between radio waves and light waves is quantitative not qualitative In other words they are identical in every character Istic except wave length Mr Mouromt-lef- f aayi that there is more difference between long and short radio waves than there is between short radio waves and long light waves To illustrate this he explains that the longest radio wave in use is 100000000 times as long as the shortest radio wave ever produced whereas the shortest radio wave is only 1000 times as long as loud-speak- er The Smallest Real House tU HE bouse shown in the accompanying illustration may not be the moit

Believed to Be Capable of Piercing the Earth’s Atmosphere and Shooting Through Outer Space 35 Million Mile to Mara the longest visible light ray Hence ha concludes radio waves are merely “dark light" Visible light waves those between the long red and the short violet constitute a very small percentage of tha total range just ae audible sounds are a small fraction of all existing noises Many of these have wave lengths or frequencies much too high or too low to set up corresponding vibrations in in the human ear drum the scientist explains “Nature has been kind to impoe these limitations on our eyes and “Cerears" say Mr Mouromtseff tainly all would be chaos and confusion if we could see and hear everything On the other hand science would bo seriously handicapped if it had not perfected instruments and apparatus to detect the invisible and inaudible “At different times certain people have interested themselves in the possibilities of communication with possible Inhabitant! of Mars If anything of this sort is ever to be accomplished it will probably have to be done by means of ultra short radio waves" Some 25 years ago certain known facts of radio communication convinced Dr A E Kennelly professor of electrical engineering at Harvard and Professor Oliver Heaviside English scientist that there must be a sort of cushion or atmospheric layer 100 or more miles from the earth's surface This has since been known as the layer “Of course it is a theory just as atoms and electrons were created by theory to explain certain phenomena" resumes Mr Mouromtseff “but we are certain that not only heat and light waves can penetrate something like the Heaviside layer but that all radio poison-iv- y Irritations msy be bad from an easy and simple method which Is described In Popular Mechanics bv a scientist of John Hopkins University Ivy poison it is explained is in the form of an oil and that the dissolving and removal of the oil before it can be absorbed into the skin is the most effective cure The method is to prepare a hundred er so pinches of absorbent cotton fill a saucer with alcohol of seventy-fiv- e per cent or greater strength dip the cotton into the alcohol and sop up the poisonous oil throwing each pinch away as soon as used and being careful not to allow the alcohol to dry on the skin The alcohol should be frequently changed About fifty applications are usually sufficient for a small patch of poison The first thirty applications should After not be rubbed merely sopped that It Is well to rub with the wet cotton each time At last rub vigorously to bring the dissolved poison out of the pores and to break any small blisters that already may have formed The more extensive the poison patch tha more swabs will be needed and the more treatments with relatively varying degrees of pressure are necessary Fifty swabs are sufficient for a patch the sue of a silver dollar iELIEF of y J I ed Alcohol as a Cure for Poison Ivy House of A Complete Three-StorRoom Built on a lot Only Ten Fret Wide " A or ‘dark light’ waves less than seven meters long will penetrate that layer and leave the earth “It is conceivable that the power wo have succeeded in getting into our beam is sufficient to pierce the Heaviside layer and travel the miles to Mars: It is possible that such email power may carry to such great distances because of the fact that practically all of the intervening space is really a high vacuum and does not therefore absorb the waves once they get through the earth’s atmosphere" Today Westinghouse engineers are talking on euch a beam from a radio station on top of the company’s research building to the roof of the more laboratory engineering than a mile away where a parabolic metal mirror gathers the waves and passes them through a special detector tube to an ordinary little radio receiving set where they are amplified and made audible Radio beams are identical with light beams except that they aro of different frequencies or wavelengths and invisible according to the In actual service comengineers waves munication on the radio-opticis dependable and almost immune to theft interruption and interference Its operation cannot easily be “jammed" or crippled by an enemy the beam must be found before its message can be detected and by means of reflecting surfaces it can be sent long distances In a searchlight the rays originate at one point reflect from a parabolic surface and pass out in a narrow beam In the newest achievement the waves reverse this process by striking the parabolic mirror where they are reflected to a short antenna and detector tube located at the focal point corresponding to the source of light in a searchlight Since intervening hills or al Making Music by Electricity realm of musical production being entered by new Instruments which are dependent on electricity for their tonal effects German inventors seem to have taken the lead in this field Among these electrical instruments for producing music is a device perfected by Dr Trautwein the Berlin scientist It resembles no existing instrument and can produce only one tone at a time but the possibilities It can are held to be considerable play by electric production and megaphone any desired tone or interval and besides can evolve new timbre that differ from those of any known instrument Moreover it can imitate existing Instrument Another electric instrument produces sounds of more novel curious and grotesque character The octave is divided into ten parts and strange intervals arise Two systems of electric pianofortes The plan of also have been devised Oskar Vierling is to transform the cusof a pianoforte tomary Into an electric production To accomplish this Mr Vierling has removed the heavy metal resounding board of the pianoforte and placed magnets near the strings designed to transform the mechanical vibrations of the strings into electric vibrations from which the modified and purified tone reaches the megaphone which finally makes it audible This eystera enables the inventor to give new posHe can sibilities to the Instrument also assimilate the pianoforte tone to that of th organ string or THE physicist of the University of Berlin Th tonal effect of the pianoforte th faculty of prolonging a tone and of making a crescendo or diminuendo Moreover the instrument can at the same time perform the services of a phonograph and of a radio and th effect is extraordinary and surprising Doubts however have arisen whether the Nemst pianoforte would be equally fit for playing music that depended upon color effects refinement of touch and pedal work buildings absorb both types of beams the engineers found a way to reflect the ultra short radio waves so this handicap could bo overcome It is believed that the ultra short wave will be adapted to many practical usee in the next few years and that it will prove of commercial value by supplementing radio and other present forms of communication EATTIER painting is a very still pursued in Mexico where the early Spanish conquerors found it in use and much to be admired An application of the idea is the subject of an invention
