Successful drawing lessons by radio la the lAtest development In the ex periment to use broadcasting for classroom Instruction being con ducted by the Oakland public schools, co-operating with Kelt), the General J-eltrle Pacific coast station. Children assembled under normal classroom conditions In eight differ ent schools in the city have just com pleted a course of six drawing les sons. The problem assigned was to create an original design for a Christ mas card using the Christmas tree for a decorative motive and actually produce individual work In response to suggestions issuing from loud speakers. Greater Originality. Exa mination of the papers turned In reveal the fact that by radio greater originality is accomplished than when lessons are conducted in person by the teacher before the class. As a result, it was stated, teachers will find an inspiration to try other subjects, apparently as im possible as drawing seemed, in the tests to find out how to use radio in public school work. In sharp contrast to other lessens broadcast by KGO, when children only listened to lectures without re sponding, the course just completed was designed to bring * type of re sponse which could afterward he col lected and judged. Children In the eight schools selected to take part were seated at desks with ample spare between, and care was exer cised to maintain the uncrowded classroom atmosphere throughout the lessons. The first lesson of the series re quired paper, pencil, paste and a small dark circle of cardboard about one inch in diameter, on each pupil's desk. Teacher at Microphone, Tn the studio of KGO miles sway from the schools, at a given time, the radio teacher spoke her instruc tions before the microphone. She be gan by briefly suggesting the Christ mas spirit and the beauty of its ex pression in art. Then, she proposed to her invisible pupils that they set about creating Christmas greeting cards for their ' ' nds. They were requested, how r. to conform to the general principles of proportion, massing and values, which are accepted as funda mental in the art of design. Step by step in the next lesson the radio teacher explained how to cut a Christmas tree tn black paper silhouette, rightly proportioned to fit Into the background already pre pared. Great enthusiasm was shown. Some, of the trees, cut out of pa per, were long and slim, some were pointed with Gothic grace, some wide spread and protective, some exagger ated for an effect of humor, some containing many fantaatlc branches, and some were smooth in outline as though burdened with snow. I.ed by the suggestions of the radio teacher the various kinds of trees were criti cured by students themselves. Finishing touches were added when there came over the air the com mand: "Place candles on your happy t.ee!" After a pause, with joyous humor which was irresistible, the radio voice continued, "Sow light them.'" Hundreds of pencils, like a flash, went to work. Halos were drawn around the candles, or little thin streams of smoke were made to trail upward across the designs. From the Instruction "put a candle on your happy tree," and from other suggestions given by the radio voire, It was found, when the papers were collected «r,d examined, that there was scarcely a duplication In decorat ing the tree. HOOKUPS REDUCE AMPLIFIER NOISES ^^Wany radio fans find they have dis agreeable noises In their receiver* when using two steps of amplification. This 1* found to he especially true when two transformers of a high ratio era employed. There are three ways of reducing the noises. The first Is hy shunting the primary of the second step trans f rmer with a fixed condenser or re sielhrire, the capacity or resistance be ing governed by the ratio of the trans former. if two transformers having a ratio of five to one are used the correct cnpaclty will he In the neigh borhood of .001 mfd. The second method Is by shunting the secondary of the second stage transformer by a high resistance, the correct value again being determined by the ratio. The third method of reducing the noises Is the same as the second, only n small condenser Is used In place of a resistance. The latter method Is, however, not the best, ss It tends to reduce the volume of the overtones, which are essential for good repro duction. Nfw Record for Amntrur*.

How to Construct Hoyt Augmentor; Coil and Circuit Data for Three and Four-Tube Sets Are Explained By A. J. FAR AON. There have been so ‘many request* for roll winding information and com plete circuit data on the augmenta tion system of signal amplification, that in order to satisfy these requests It has been deemed advisable to go into the constructional details of one of the preferred forms of this circuit's application before completing the de scription of the several methods of accomplishing this result. The circuits to he recommended for the forms of slgnaf augmentation thus far presented are preferably of the three and four-tube combinations, as shown In the illustrations here with. The four-tube combination is particularly adaptable for those tier sons who are excessively troubled with interference, or for those who de sire to play the distant broadcasting stations while the locals are on the air. On the other hand, the three tube combination will prove very satisfac tory for those broadcast listeners who only desire to play the locals, with out having Interference between them, or who desire distance after the locals have gone off the air. This last statement must not be taken too liter ally, however, for some very remark able selective distance work has been done with the three-tube outfit while the locals were all at work. For ex ample. at a distance of 25 miles from Newr York, the three-tube augments tatlon set has been regularly playing from 25 to 25 stations per evening, all, of course, on the loud speaker and with good volume. The foregoing re marks have been intended as a sort of a guide to assist the builder to de termine the type of set he may rare to construct. Hg- I. Three-tube agumentor receiver, having two stage* of audio frequency amplifica tion, one of which is combined with the augmentation tube. therefore Is only to be used In ron junction with the four-tube set. and the builder who only desires to build the three-tube receiver need not wind this part of the roil. In that rase it is only necessary to follow the roll dimensions as shown on the draw ■inas. leavinK off the primary entirely. The antepna. In the rase of both the three and four-tube seta, should antenna coil should be made by the complete elimination of the broadcast ing station which interferes to the greatest degree when tuning to dis tant stations varying from three to five meters from the locals. While it is not the purpose of this series of articles to specify equip ment of a particular make, it Is Im perative, nevertheless, for the sue Ing purposes are 13-plate TT. ft.

So specification is given for this coli as it will vary slightly—foi synchronism in tuning calibYation— depending on the antenna, and It is de sirable to add or remove a few turns until the dials all tune alike.

For the last radio stage, either of these transformers functions nicely, as, of course, will many others. Wiring Diagrams. Wiring diagram for the three-tube receiver Is shown In Fig. 1, and that for the four-lube set Is Illustrated In Fig. 2. These two diagrams are self explanatory, and should any doubt arise In the mind of the builder as to their more simplified theory, he Is re ferrrd to the two preceding articles on augmentation which hate appeared In this paper, under the dates of Dr ■•ember 13 and 3a, respectively. The only substantial change in the dta grams of today over those schematic diagrams which appeared In the previ ous Issues Is In the addition of s stage of audio frequency antpllflcatlin and In the method of antenna connection. In the matter of tubes. It Is recom mended that 201A or 301A types be employed, although the detector tubo may lie a 200 type If the builder so desires, In which case the proper plate voltages must be used. But, as the rheostat setting Is not at all rrlll cal In this circuit, the hard tubes may ha employed to advantage, and one liieistat for all of the tnlws will then suffice.

If underground radio transmission and reception can be perfected it Is believed it will lie valuable in saving the lives of entombed miners. If min e* a entrapped underground could re ceive from a surface station they could Is* 1 ept Informed of the progress of i lie rest lie parties In some cssps. even direi led to different parts of the mine wheie their rescue could he facilitated or fresh air supplied. "There are four chief factors that affect electromagnetic field Intensi ty," says the report, "namely, dis tance, wave length or frequency of carrier, efficiency of transmitting an tenna and attenuation. Of these at trnuaflon is of particular significance In underground radio communication. ‘.attenuation Is dependent u,Mn two f.’.ci’OTS—namely, the decrease in cur rent due to the geometrical spivndir? out of the electromagnetic wc.es in space, and to the absorption of waves in passing through the strata." RADIOPHONE SAVES LETTERS neveland, O., Jan. 9.—Practical use of the radio telephone for private con versation between individuals has been demonstrated by Donald H. Johnson of Kuclid Beach Park, this city.' For two years he has employed the radiophone for a dally chat with his father, l)r. William H. Johnson of Collins, O.. about 70 miles distant. These ronversations were carried on in broad daylight with the same reliability of a private telephone. tu issue one or two cautions, together, perhaps, with a suggestion for cor re«*tion of dimensional error In locat frig the augrnentor or booster coll. The augrnentor coupler has been de signed around standard dimension tub ing. and In fact there are on the market one or two makes of varlo couplers which can be purchased and rewound for this circuit. The side view, showing the three windings on the stator, is shown in Fig. 3 at “A/* Tills member of the coupler is made of a 1 3 4 inch length of three (3 Inch outside diameter tubing —bakelite.

C.—Urban and rur al radio fans are beginning to demand dally weather reports and time sig nals /rom neighboring broadcasting stations, and It is believed that event ually at least one station in every lo cality will have to broadcast both lime signals and local weather fore casts. Complaints that certain sta tions do not broadcast either time sig nals or weather reports, or that no station in a certain locality pfts these essential reports on the air, are be ginning to come into the department of commerce and the weather bureau. Neither governmental office has any thing to do with the matter put on by private broadcasters, and yet the government is anxious to serve all fane who desire such data. WJAX Is Under New Ownership Station Acquired by Goodyear Tire Company; to Be WEAR. Radio atation WJAX, Cleveland, which has been operated for the laat two yeara by tne Union Trust com pany, has been sold to the Goodyear Tire and Rubber company, which will take charge of the broadcasting im mediately. The call letters are to be changed to WEAR, In announcing the purchase of the station, officials of the Goodyear company stated that the broadcasting from WEAR would be on a larger scale than in the past, with programs of the finest music obtainable. The Union Trust company will con tinue to broadcast twice daily market and produce quotations, weather re ports and financial news, but the re ports will be more condensed than In the past. These reports will be broad cast between 11:30 a. m. and noon, and from 3:30 to 4 p. m. An unusually elaborate program la being arranged for the evening of January 15, when WJAX will present Its farewell and WEAR Its first pro gram. RADIO V << our tray of lUriin Digest.)

The next Victor concert will he given on the night of January 15, with Mrue. Frances Alda and Miguel Fleta as the principals. These artists have acquired fame on both the opera and concert stage and their programs will include music in which they have appeared at their h# st during their distinguished ca reers. The first of these radio recitals under the auspices of the Victor com pany was given on January 1, with John McCormack and Lucrezia Bori participating, assisted by other Vic tor artists. It was announced at the offices of the American Telephone and Tele graph company that more than 21,000 messages have been received thus far from radio listeners in, all of them urging a continuance of the classic recitals. The messages have been received from nearly every state in the union and from several points In Canada, some of them from men and women who are In isolated places. There p.lso is a great number of messages from those physically afflicted. 3 CONTINENTS ARE HEARD IN AFRICA Receiving the radio signal* trans mitted from three different conti nents and at considerable distances in the course of one evening s re repTion is an exceplional accomplish ment for a radio amateur. Clifford C. H. Frazier, manager White's South African Cement com pany, Whit’s station, South Africa, in sist* that In addition to receiving the local stations at Johannesburg and Capetown. Africa, he also listened In to station 51,0 in Kngland, a distance of more than 2.000 miles, and to the program broadcast from the Westing house station, KDKA in Pittsburgh, a distance of 8,300 miles by air line. This is believed to be tha most southern place in South Africa so far recorded that has listened to an American broadcasting station. Old Rusty Saw Gives Radio Pans Good Mu-ic Rerrien Springs. Mich., Jan. 8.— That it is possible to obtain the sweetest strain of music from the tooth-edge of an old saw was proved recently when E. G. Johanson, vio linist. at broadcasting station KFGZ, "The Radio Lighthouse, played sev eral familiar tunes on an old rusty carpenter saw. Letters have been coming in ever since, commenting on this Unique musical instrument. As far as if is known, this is the first time that a saw solo has ever been delivered over the air.
