DAYLIGHT-SAVING THEME OF FIRST'RADIO DEBATE Hundreds of radio fans in Washing- ton and others in the eastern section of the United States listened 1n on.the first debate ever broadcasted by radio, which was held last night at statfon “WJH,” otherwise known as Wnite & Boyer Company. Those who heard the debate weré invited to act as Jjudges, and their decision will be an- nounced Iater. ’ The subject of the debate was “Re- solved, That daylight saving is an advantage.” C. L Kephart, represent- the Miller Debating Soclety o | National Univeraity Law School, up- held the affirmative and Thomas £. Rhodes of the Alvey Debating Soclety of the same institution, the negative. ‘Mr. Kephart contended that day- light saving would result in a great saving of fuel, that it was a success during the war and that it is of bene- fit to working' people, as it gives them more time for recreation and to spend with their families. Mr. Thomas de- plored the attempt by legislation to control the habits of the people, and declared that daylight saving is di- rectly inst the interest of the farmers He also maintained that daylight saving robs the public in general of the morning rest, which Is fihe sweetest hour of sleep One can AANERNAYN AALANNS AN LEAN / snmun dfi’lfillllli- REREER i S PALAISROVAL The Shopping Center—11th and G Sts.

However, condensers may be constructed in a few minutes, and are handy things to have about when experimenting with the making of sets. Every one who intends making or installing a radio 7. | apparatus should know how to con- struct these tmportant little devices. The simplest type of condenser consists of tinfoil and waxed paper, and is made as follows: Secure some waxed paper, which may be purchased already prepared or may be made by soaking heavy note paper In parafin wax; tinfoil, which must be free from tears or pressed out until free from wrinkles or creases. , From the waxed paper cut three strips, e: two inches in width, and two ai one- half inches long. With a sharp pencil mark smaller rectangles on ‘these, making the lines % of an inch from the edges so that the marks will form rectangles 3 inch wide and 1 inch long (figure 1), Next, cut two pleces of small sized, many stranded, flex- fble. insulated wire, each five or six inches in length. For half an inch on one egd of each plece carefully cut way thd insulation and untwist and flatten the fine wire strands, figure 1A. Place one of these pleces of wire on the strip of paper with the frayed and flattened wires inside the pencil mark at one end of the strip, figure 1B, and sgcure in position by a few drops of IMelted paraffin outside the pencil line. Then cut a strip of tin- foil one inch in length and half an inch wide and carefully place it on the paper with its edges even with the pencil marks. Place a drop of melted it in position and place a second strip of paper over it Place another strip of foil one inch long and half an fneh in widthy upon: this, using the pencil marks tb center it ure it with melted parafiin as you do the other strip. Place the second wire on this last flplua of paper with the frayed ends resting on the foil and secure it to the paper with drops of But be sure to have the wire at the opposite end of the foil from the first wire, figure 1C.. Then place the third strip of paper over all and fasten the edges of the three strips with melted paraffin. Care- fully roll the whole into a small cylinder d bind the ends firmly, with fine stfong thread, figure 1D. ‘Finish by -dipping in melted paraffin pet or thumb tacks.

If you prefer, you may make the condenser as directed up to the point of rolling it and then, instead of form- ing it into a cylinder, place it in a depression, cut in the panel the size of the condenser.

This contest will be for the making of the smallest set for re- ceiving code and of practical use— the set occupying the smallest space. For this the prizes will be, first, $50: second, $30: third, $20. One grand prize of §100 will be offered for the best loud speaker of the maker's own design throughout.

The bornite is usually pointed, while the zincite'is just a small mass held in a cup or clamp of some sort. A combination of silicon and antimony, in which the antimony {s somewhat pointed and rests with moderate pressure upon the silicon, is also used to some extent. This combination also functions without a local bat- ery. ~ In the case of the detectors requir- ing a local battery, means should be provided for varying the voltage ap- plied from the local battery.
