few seconds, it is true, those 'being filled with anguished anxiety, and wrought with danger, but it flew! Twenty years later! In twenty years youthful science has developed in the subject of aviation with astounding rapidity, and today aviation has be- come an industry. Flights of hours and hours, oceans spanned by glorious flights, and the earth spanned innumerable times. Perhaps the most important item in connection with the airplane--in fact, the heart-is the power plant. The comparative efficiency of the modern power plant 1ieS in the perfected four-cycle explosion motor, using gasoline as fuel. Of this type of engine We have two types-the water-cooled and air-cooled. Of the two, however, the general trend of usage is toward the latter. VVhy? This is explained by the elimination of the water-cooling system-fre- quently a source of motor trouble in water-cooled motors-which saves the necessity of having bulky cowlings, resulting in the increase of the all-around performance of the plane. It may cause some wonder as to the reasons that cause the army to maintain the usage of water-cooled motors. One is this: Water-cooled motors have the ability to stand a greater amount of rough usage. This usage may consist of high altitude or hedge-hopping, but it is a terrible strain on the motor. Another reason is that more power can be built into a water-cooled engine without disturbing the streamline structure of the plane. The air- cooled power plant is more adapted to a steady climate, since it depends on the temperature of the air for cooling. Frederic Singer, A 9. Model Builders Seventy-nine

THE BATTLE ROYAL Place: Drafting Room, Time: After School. CHARACTERS Pencil, T-Square, Ruler, Book, Desk, Compass. Ding-a-ling, rang the bell for the last time that day. I say there old T-Square, said the Pencil, that proves I'm the most useful article in the class. They wore an inch off of me today. Uh, peeped up the inches of the Ruler sarcastically. If it had not been for me you wouldn't have been touched. . Wire draws all these straight lines anyway? just look at my slender body, brags the T-Square. You fellows seem to forget that Pm the one that holds you up all day, and keeps you off the floor, joined the tired desk. What about me ? cries the poor little book, carelessly thrown on the floor face down, I teach the boys how to use you properly. If it were not for me you would be useless. Well, if you fellows will ever get through arguing I will say some- thing, says the compass coolly, Hyou fellows seem to forget that the pupil has the biggest share in the use of us, he learns how to rule off a piece of paper, to print important things. ' We would be helpless and useless without his interest and ability to direct us all the other shop work would be greatly handicapped. Austin Casselbery, B9. Bud Lester, B9, ' REALM OF MYSTERY I am the room of mystery and wonders, and to you, many of my secrets will be revealed if' you will be so kind as to step into my shop. Perhaps the high sounding technical terms that frequently are heard when electricity is mentioned have seemed too deep for you to fathom. If that is the case, just step into my den and I will explain them to you. As you first step into my control I seem to hypnotize you, by all my buzzes and strange sounds. You hear the crunch of the drill digging its way into a piece of strap iron, and the weird voices of the gas heater of the soldering irons, or the occasional buzz of some one of my enthusiasts trying -out his finished circuit. I am still a thing of mystery, slowly being revealed to man, and per- chance I will reveal one of my mysteries to you if you are seriously interested in my progress. Some of our boys are interested in some of the more deeply scientific phases of electricity such as sound in radio, short Waves, heat, television, and others. ' Austin Casselbery, B9. ' . Bud Lester, B9. A FIELD FOR PROBLEM SOLVING Witl1out'a doubt within the next three decades ultra short waves are ordained to overshadow everything that has yet been done in the recent career of our modern radio. VVith the highest frequencies, short Waves display qualities so unexplainable and in many cases so sudden, that we shall stand in astonishment at the phenomena. Eighty
