Wai/e/nefer There are several methods of eali- brutlnj: receiving sets, but some of these are not accurate. In most meth ods there are pitfalls into which, If t the experimenter is not very careful, he will fall. Some of these pitfalls will be pointed out and a method given to avoid them. The most accurate method Is the “zero beat” for oscillating receivers. The'application of this method to the “single circuit” and “Relnartz” types of receivers will be taken up In detail. The calibration of the noriregenerntlve and neutrodyne types will be taken np also. Besides a wavemeter, which may be purchased for from $15 up to $200, a “laboratory oscillator” is needed, and a buzzer, preferably of high pitch. This *»jCOmpletes the equipment. The accu- r. ?y of the results obtained will then '’.pend first on the accuracy of th% wavemeter used and secondly on the accuracy of your own readings. The diagram of the connections will 'be seen in Fig. 1. Any vacuum vtube which happens, to be at hand, :n the size of a UV199 up, may be useuX^Tl*^ size of the B battery may be anything from 22 volts up; 45 volts is satisfactory for most tubes, how ever. The Abbottery Is whatever size the tube norm a Fly requires. No grid leak Is necessary. N T H :1 Is 40 turns on a 3V*-lnrh or 4-inoliXube. This Is shunted by C-l of ,OOOfN<o .001 mf. capacity. This will make an oscilla tor easily covering the range from 2(H) to 540 meters, even with the .<HK>5>Hm- denser, and considerably higher win the .001 condenser. A calibration for the single circuit receiver must be taken for a particu lar antenna. If It is changed the cali bration is useless. During the cali bration of this set the tickler must be kept ju^t barely beyond the point where the set 4s oscillating, L e^, the “boiling point.” This is determined by listening for a sharp click as the tickler is increased. To make sure It is oscillating touch the grid of the detector. Two clicks should be heard, one when the finger touches and one when it leaves. '"' , | Set the inductance switch at the lowest wavelength tap and the con denser at 0 or 10 degree setting. In crease or decrease the “tickler” until it just “spills over” into oscillation. Then turn C-l of the oscillator until you hear a whistle. When this whistle is heard you are not exactly on the same wavelength us the oscil lator, but very close. Now turn the condenser Ol back and forth until you get a point where there is no whistle, but that on either side of which you do get a whistler You have now adjusted the oscillator to ex actly the wave your tuner Is set for. (Remember, not the whistle, but the point between two like whistles, Is the resonance point.) Now bring the wavemeter up to the oscillator and turn It until you get the maximum de flection of the galvanometer. Keep the wavemeter as far away as you can and still get a deflection of the gal vanometer. If doing this causes a whistle in the receivers, reset the os cillator and wavemeter and take simul taneous readings of wavelength, switch and condenser settings. Take readings through every ten or ;onty degrees of the condenser dial 'aeh inductance tap, always keep ing the tickler Just at the verge 6T osclllatlo - STRAIGHT -LINE DAY DRESSES; KNITTED FROCKS FOR GIRLS N EXT to the tailored suit In Im portance, rank those simple and.

Some of these fine spring days little daughter will most likely come rushing into the house declaring, “It Is too^varm to wear my coat.” Of course one cannot blame any little girl for this burst of enthusiasm, for has not all nature cast off the mantle of" winter? But what Is mother to do? Mm JC'- it £>•4 f y ■■ for^ Simple Non-Microphonic Socket Mounting Plan A simple method* of mounting a UV- I9U socket on sponge rubber so that the bulb can be inserted in an inacces sible place without holding the socket with the other hand Is here described. It Is accomplished by cutting a piece of sponge rubberv(bath sponge) in a disk inch thick and the diameter of the socket base; then cut two recesses in opposite sides S inch wide and deep as at A in the drawing. Get a ten-cent tube of para dry rjibber ce ment from the nearest garage, place the socket without the rubber In posi tion on the set where It is to be per manently located and mark the two holes that are in the base for fasten- sUl... Then draw a circle around the base. ijbfr*''the two holes and.place a brass bolt with head on the under side and out the upper- side so that the bolt will stick* about th Inch or J/j inch above the baseboard, but will- net touch the socket by Vi of an inch when the rubber is placed between. Scrape or roughen the underside of the socket and inside of the circle so ' that the cement kvlH hold well, and wet the rubber onlboth sides ^wet the socket and place in position, as shown In the drawing. Lay a light weight on top of the socket so as to compress the rubber about Vi inch. ‘ Be sure that the brass bolts are directly in the center of the holes in the’base of the socket. Let It stand until dry. When using,. Insert bulb, and on pressing Good SpringxContact Will Help Amateurs By JAMES BARR I think you will find the\followlng scheme of great benefit to iihl ama teurs. I have always had trouble In winding variometers or varioeouplers, but Just how I could attach the inside winding or secondary coil so. that I could turn it through 300 degrees, if necessary, was a 'problem. In the old All-Day Dresa of Satin Crepe. between, there Is chance for even greater diversity. The all-day dress in any of these fabrics adheres to the slim-and- straight mode, following the lines of the figure closely but allowing the in- i troduction of smart details for tin; ! sake of variety. Fullness nt the sides, shaped flounces, panels, plaitings and tiered skirts, bloused bodices, sashes, different neck treatments and" varied sleeves are among the thfngs that con tribute individually to frocks ol this There are e'en^dn the best of regu lated spring seasons unwary shifts of cold and hent, winds and rains, sun shine and shadow and little girls have such a way of catching cold at this time of the year. With knitted dresses In fashion as charming as is shown In this picture why he In a quandary? Frocks qf this type knitted of soft woolen yarns are ideal for play and school time. They protect, yet are not cumbersome; are “comfy” and practical. The frock here pictured is knitted of red wool with .white bandings on the skirt. White braid forms the collar binding and the tie. This season’s knitted outerwear for children is fashioned nfter the style of their elders. That is, the same sweater models one sees In the knit ted department for grownups are re produced In miniature for children. Tfie tuxedo sweater Coat, for Instance, and slipover with nebkline and color variations look like pocket editions of big sister’s very own. An especially attractive and desir able model in HUlputlan size is knit ted of downy brushed wool bordered with plain stitch, or else with revers of the same. It has long sleeves, tailored pockets and comes especially in camel color, gray or white. Sptngt mntr FltxiWt wires Shtff »r toutotrtf.

If any length of service is desired, the drain must be light, for dry cells simply cannot furnish even a moderately heavy cur rent for more than a few minutes. They will .“polarize” quickly If more than the safe current Is drawn, and the voltage will fall off considerably. The batteries must then be discon nected and aHowed to stand for a short time. Two ordinary six-inch 'dry cells should be allowed for one WD11 or WD12, while three are satisfactory for one, two, or three UV199’s.^ Under ordinary conditions, they will then be useful for six weeks or two months. If the set Is operated infrequently, they undoubtedly will last longer.

Pinkham’s Veg* etable Compound a Trial First Fairvi ew, S. Dakota.—“A year 1 was sick in bed for three weeas an< doctor said I would not be any better without an opei^tion. I had bearing- down pains and sick headaches, with pains in the back of my neck. I felt tired all the time, down-hearted, and got poor and pale and was scarcely able to do anything at all for some time before I took to my bed. The doctor said one of my organa waa out of place and caused all my troubles. I was too weak and run-down to think of an operation and as one of my neighbors told me about Lydia EL' Pinkham’s Vegetable Compound, I began taking it. I have received great relief from it and recommend it very highly. It cannot be praised too much in cases of female weak ness.”—Mrs. O. M. Ring, Box 106, Fairview, South Dakota. New Jersey Woman Writes Camden, New Jersey. — “I take great pleasure in writing you this tea- timonial. I was a greaCsufterer of woman’s ailments and doctors told me l8 years ago that I must have a serious operation to remove some of my organs. I refused to have it done and took a full course of your medi- icines for six months, then after the full course I took a bottle of Lydia E. Pinkham’s Vegetable Compound every week or two. also Lydia E. Pinknam’a Blood Medicine every Spring. I am well and stout and stfiO have my organa they wanted to re move. It was while I was in the ital that I heard your medicines by other patients there. I isve recommended them to my friends and to my own family. You may use this testimonial far and near, from the smallest paper to the largest, and I will gladly answer let ters from women who wish to know what the Vegetable Compound has done for me and what it will do for them if they give it a fiir trial.” — Mrs. J.

Through neglect, some female trou bles may reach a stage where an operation ia necessary, but most of toe common ailments are not surgi cal ones; they are not caused by serious displacements, tumors or growths, although the symptoms may appear the same.
