V. and rotor form are preferably ^poaked In paraffine, but this Is not | i^esgentlaL Begin winding the card- ( t>oard tube, starting % inch from one through a sumii noie, as shown, If.- / *n(* wind on 88 turns of the No. 28 Wire, keeping the turns cloee to- Jfether but not touching. Then, / -; faring the wire across the tube as $hown In Fig. 37, leaving a space of .j -One inch bare and continue to wind v 1 <*m another 80 turns of wire. In ;; r i.. Winding, take off three taps -tfrorn each section, one at every „ y. * twelve turns, beginning at second turn K'f _Jfrom top and leaving two turns at bottom of winding as shown in Fig. 37, ?T, T, T, finally passing the end ' through a hole as shown. The whole v should then be covered with paraffine, or It may be shellacked, although * fcheilac will decrease its efficiency and paraffine will serve every purpose. In ^ the center, at the bare space which has been left, a ^4 Inch hole should Jbe bored as shown In the cut. The t>ext step Is to wind the rotor form, which is done by winding on twenty- ' Iflve turns of No. 20 wire (starting through a fine hole as shown) which * jforms the "tickler" coil Fig. 38, A, - • and leaving the two ends of the wire about 6 inches long and running the last end through a hole to hold it Then, at the other end of the rotor, wind on forty-two turns of No. 28 "wire to form the secondary Fig. 88, ^1, and leaving free ends of wire about 6 inches long. Through the center of .the rotor-form, a hole should be bored hi inch in diameter as shown. The next step is to mount the coupler, which is done as follows: In the fibre panel, bore a % inch hole two Inches from the top and 8% Inches from one side. Fig. 39. In -. the lower corner, place a switch with !slx contact polpts A, and on the right * I. Jhand side drill sijc 3-16 inch holes f Jfor binding posts B. Then make and place the shaft In the rotor, secur- , tng it by glue, sealing wax or by jneans of nuts, according to your Anechanical ability, and attach the two * {>arts to the panel, fitting a dial and knob to shaft and mounting the panel on the base. In connecting up, the primary, secondary and tickler wires are connected to the six binding posts and the ft* tap-offs sathe primary i^«r coll are connected to the switch cootacts as shown In the cut with one of the primary wires in the switch post. Then, when the coupler Is to be set up, the aerial is connected to one of the primary posts, the ground to the other, the secondary posts 4re connected with the grid circuit and the tickler posts to the plate and receiver circuits, ail of which is shown in the diagram Fig. 40. A variometer may be made In a very similar manner, using two cardboard tubes, one about four Inches In diameter and three inches long; the other three inches long and about three and three-quarters Inches In diameter. The dimensions should be such that the small tube can turn freely, without touching, within the larger tube and the smaller the space between the two the better; but yon must remember to allow for tbe thickness of tbe wire to be wound upoa the inner tube. First, measure carefully the exact centers, so that wben a shaft fastened to the inner tube or rotor is passed through the larger tube, the inner one will rotate freely and evenly without touching or increasing the space. The entire efficiency of the variometer depends very largely upon the accuracy with which this Is done. Starting with a small hole about % inch from the outer edge of the smaller tube, wind on about twenty turns of No. 24 double-coated, cotton-insulated copper wire, being careful to keep the turns separated. Then skip a space of about an Inch, as shown in Fig. 41, and wind on another twenty turns, finally running the wire through a hole, fastening both ends with a drop of glue or sealing wax and, leaving five or six inches of free wire at each end. Starting the same way, wind the larger tube In exactly the same manner and being sure to wind in the same direction. When all are wound, mount the smaller tube on a shaft inside of the larger tube, fastening shaft by glue or sealing wax dropped on from inside, and mount as shown in Fig. 42. Finally, connect one end of the stator wire to one end of the rotor wire, leaving plenty of free wire to allow rotor to revolve, and lead the other two ends to binding posts, as shown, being sure to keep that to the rotor loose to allow free movement. The shaft to rotor should be equipped with knob and dial as shown in tbe cut and the whole mounted on a fibre or bakellte panel on a proper SIMPLE CRYSTAL DETECTOR RECEIVING SET A veiV simple and effective little Bet (Fig. 43) under favorable conditions and with a good aerial, will pick up the broadcast music, signals and other sounds from stations at considerable distances. No specific r%uge ' for this or any other set can be given, for the efficiency of any set depends upon a great many conditions and influence The length and height of aerials, the proximity of high bulld- , ings, electrically charged cables or wires, the perfection of Insulation of v aerial, adjustment of instruments; all 5 affect the range of a receiving set (and, in addition, there are climatic «nd other conditions to be taken into .^consideration. * ; In the diagram A represents the aerial, which should tye a single *\ire as nearly 150 feet In length as possible and as high as it can t>e placed. B Is the ground which ahould be made by scraping a spot on gas, water or radiator pipe and ' soldering the wire in place. C is a Variable condenser In the ground lead, and for this set should be about .0005 microfarads. D is the crystal detector, E the telephone head set and F a -variometer. The variable condenser and variometer may be purchased ready-made 'from any dealer in radio supplies and while they may be made at home yet It is far more satisfactory and Just about as cheap to purchase the stock instruments. The same Is true of the crystal detector and head set. You «hould, however, be careful in selecting the galena crystal to be used with ; ?^uch an outfit as this mineral varies greatly In its sensitiveness. The best plan is to purchase a pound or two of the crystals and test a number of pieces by means of a buzzer. You will probably find that while some crystals are absolutely useless others are fair and a few are very sensitive. To make up such a set is very simple, as the various parts are merely connected with Insulated copper wire, as shown In the figure, using binding posts which may be purchased for a few cents. The whole may then be mounted on a piece of fibre-board or bakellte or it may be set up on a neat board or block and enclosed In a case with a hinged cover. Such a set, Including j all connections, wires, insulators for aerial, etc., should not cost over $20, and will be found far superior to many ready-made sets costing much more. Crystal Detectors and How te Make One.--The crystal detectors used in sets such as described are of various forms. Fig. 44, but in all the principle is the same and they all consist of a crystal cup or bolder, bindingscrews and an adjustable contact of fine wire. They are not expensive instruments and it Is usually easier and cheaper to purchase them ready made than to make them, but they are very easy to construct and any boy can make a practical detector In a few hours. One of the simplest Is shown in Fig. 45, and consists merely of a fiber base, a strip of brass about 1-16 or 1-8 Inch thick bent in the form shown; a brass plate which can be moved from side to side on a pivot, to hold the crystal; a line coiled wire and binding-posts. The plate holding the crystal is connected with one post and the brass strip holding the wire to the other post. If possible, use platinum wire for the contact, hot this is not essential. jjMany "Gobs" Radio Fans t Among the thousands of radio fknS fn America today are hundreds, perliaps thousands, of former "gobs" who jsailed the flowinp main and who struggled In the old days to get near :lie bulletin boards at the scuttlebutt, here radio messages were posted on te sliips that served- as army transirtsJ.

A set of this type should be mounted In a box Ml than 1 ft »my uac mCa t UAltUHI iCClitlug toward white when summer comes on. But the vogue, asserts a fashion writer in the New York Times, for that color this year Is much more than a natural tendency. It Is a passion. It is a fad. It is a necessity, indeed, if you wish to be classed st all In the circles of smartly dressed women. And who does not, pray tell? This summer the evening dresses are white, tbe afternoon dresses are white, the morning dresses are white, the suits are white, the coats are white, the capes are white. There Is no article of attire that escapes the general mode. And really there are more stunning things being done la white than have been made la all the other colors put together. Travelers returning from Paris bring back the news that everything la white there, too. One society woman drew from her trunk ot Parisian White Suit of Homespun, Marmot Trimming on Collar and Cuffa, clothes no less than four dresses of all white. "Well," she said, "what else could I do? They had nothing but white, and the French designers were out to' despise you if you dared to choose anything else In the way of color." Wben you are stricken with the pervading tendency of white you will find all sorts of compensation, for there are beautiful things to be had In that medium. And, it seems, that the color. If It may be called a color, has stepped away from the field of suitability only for certain types. Indeed, there is about it an adaptability to all types of which jot^ woqld hardly have «nyt. The Color Problem . There Is much value In tbe way that white is handled and tbe question is whether to relieve It with a touch of black or color or whether to leave it with nothing but Its own blank surface to make it notable. Then there is the problem of the quality of material, for there is ail the difference In the world between the thick, woolly white and the thin, silky white. One type can stand one and another type looks well In nothing but the other. It is on this ground that you must make yoor decision, and to that end 'it Is MlFy TO Wudy yourselr TtxM 131 rely new angle and learn just what you can stand In tbe way of white and just what will throw you into the back^roUftd, as it were. An evening dress of white which, though this particular model came from Parte, Illustrates a fashion which Is most successful and popular right here. It is made of white moire and this particular model has its edges and its bouffant side drapery faced with cloth of silver. There are a stiffness and a pertness about tbe draping of this heavy silk which are entirely new and which havS reached a rare degree of smartness. And when it is done in white it 's most particularly effective. One cannot make a mistake by choosing a dress of this character. And, if one should live to regret the day of purchase, there is alw&ys the dye shop, which will transform It for you In the twinkling of an eye; ot perhaps U woald be more accurate to say. at the end of six weeks. The white suit has reached the racme of its expression and. for city or country wear, it is the thing of the {moment. The thrilling thing Is to see how msny different styles are applicable to white and how many varying materials adapt themselves to the mew Idea. There is one, for instsnce, an outfit made of a white homespun woolen material with the roughest sort of surface. Then the trimming is {done with bands of marmot fur, making a delicious contrast and a most effective spotting of decoration. The coat of this suit is one of the incwcr Sun with its bioused long .fwaist and its open sleeves. Nothing «bout its line Is exaggerated, and yet |it /conforms entirely to sll the demands of the new silhouette. You will sflnd that, more and more, suits will jbe made with coats or Jackets cut Rafter this style and that women will $>e liking to wear them for the reason Jthat they indicate so pleasantly all of jthe smartest lines established by the fashion of the season. The hat worn with this salt is made <tof a soft white felt that Is so shaped Bthat It flops picturesquely about the face. Then it is trimmed with a thick roll of dull brown velvet that chimes in with tbe color In the salt's trimming of fur. All Sorts «f White Suit* There are all sorts of white salts to be found In the shops, snd many of them carry a large degree of smartness. There are those made of Jersey, those constructed out of the heavier varieties of white silk, those made from tweeds and twills and flannels. Then there are other white suits made after the popular Idea of a combination of materials. There will be a homespun jacket, for example, and that will be worn with a plaited silk skirt. Or you will find a white flannel sleeveless Jacket combined with a onepiece silk dress made from that crtsn variety of shantung silk that makes such Interesting summer frocks. Again there will be a flannel skirt and a silk coat. ' There are myriads of one-piece dresses made in white. Especially the linen ones are good and, as the season advances, surely more and more of them will be seen. There are coat dresses made of heavy white linen with rolling revers collars and large pearl buttons to set off the smartness of their lines. There ;ire others made of this same material which are supplemented by soft little collars of tucked organdie and net, with frilled and lacy trimmings kept always very narrow and unpretentious in style. Sometimes there will be a little color Introduced Into the belt, though not always. There are dashing little red patent leather belts and black ones that are very interesting. **Tanlac has restored my health and built me up fourteen pounds In weight," said H. W. Morrison, 4768 Thrush Ave., Sit. Louis, Mo., agent for the National Life Insurance Co. "Two years ago my stomach west wrong and I could not eat anything without suffering agony afterwards from heart palpitation and shortness of breath. Some nights I was In so much misery my wife had to get up and try to get me some relief. My health got to be so poor I had to stay In bed for weeks at a time. "What Tanlac has done for me Is nothing short of wonderful. I now eat anything I want, sleep fine, snd am working full time every day; in fact, I'm In splendid health.

But always the teacher pleaded with the student and often said: "You will suffer some great inconvenience, if not actual tragedy, some time, by reason of this refusal of yours to study orthography!" Yet still the student was obdurate, and said "blah." One day, after the obdurate student had grown to manhood, he poisoned himself eating oysters in "Orgust."

But they are a new sort of ruffle. They are narrow and plaited and massed together, making a neat 'sort of frHllnes8 rather than a careless sort, if you understand the distinction. The organdies that are coming from Paris sre lovelier than they ever have been, for they are redolent of new touches that make for charm plied upon charm. There Is one which has a rather narrow skirt for Its founda- ,tion, but *he nature of the materials keeps 't held out in a stiffness that can only be had by using organdie. Then the skirt is trimmed with seven rows of tiny frills In groups of three. Not only that, but the frills are mads by shaping them into petals that run along one right after the other. Above the groups of ruffling there are groups of handmade tucks, of course. Then on the bodice the same Ides of trimming is carried out and the armholes <tre left plain with no sleeves to carry on their interests.

White hats are enormously good, and it Is probable that you will see more and more of them making rbeir appearance upon the streets, even of the city.

TO MAKE CREPE PAPER HATS •haps Is Obtained Sams as With 8traw Braid, Using Buckram Frame or Hat Form. Tw>o folds of crepe paper, any ahade, a tube of paste and silkateea or other soft thread to match the paper used, are all tbe materials naeessary. Cut the crepe paper Into strips three, Inches wide, varying the width if a wider or narrower braid is preferred. Roll the strips up and pin or fasten them with rubber bands, to prevent tangling. (To cut the paper evenly, draw it from the cover the desired width and cut through the fold with sharp shears, using the edge of the cover as a guide.) Fold each strip lengthwise through the center and then again so tbe raw edges do not show, making tbe strip about one-half inch in width. Braid the three strips carefully, stretching as tbe braiding Is done. Begin at the center of the crown snd saw on the underside, sewing each strip under the edge of the preceding one. joining the ends of the strips with paste when more braid is needed. Shape just as would be done with straw braid, using a buckram frame o»* a hat for a form to prevent draw* ing the braid in sewing.
