THE GLIDING AND SOARING SCHOOL 149 the air. If the machine rears up, push the stick forward a bit to bring it to the level again ; if its right wing dips, push the stick to the left ; if the nose dips, pull the stick towards you. All your movements must be quiet and efficient. As regards your lateral steering, better not worry about it at present, but if your machine goes into a turn, which you can easily tell by noting the position of your fixed point, then press the rudder-bar on the other side ; that is to say, if you find yourself turning left, push the right foot forward and vice versa. " But you must do everything smoothly and without any fuss, and you'll find this much easier than you think. Your instincts will help you far more than they do when you're steering a car. Now come along and have a shot at it." One of them takes his seat in the pupil's machine, which we have brought to a perfectly level spot. The wind for these first efforts must be only a gentle breeze, with a velocity not exceeding twenty feet a second. On either side of the launching rope are some three or four men, waiting to start. Before the novice takes off, I show him the neutral position of the control lever (" stick "). " Now press just the least little bit," I tell him, " no, that's too much. Ah, that's right." It is usual for the pupil to give the words of command at his first lesson. " Pull out " he cried, usually with some hesitation. The crew walk about eight steps. " Run," is the next instruction, but some pupils can get no further than that, and often I have to interpose with a hasty " let go," to prevent the rope breaking. To be a good teacher of soaring you must be able to divine the feelings and secret reactions of every pupil from the way his steering affects the planes. All teachers must practise the graphology of the air from the moment they give their first lesson. This affords plenty of opportunity for observation. One pupil does simply nothing at all, does not push the lever the least bit, but the machine flies perfectly. Five or six seconds his first flight lasts.
150 KRONFELD ON GLIDING & SOARING " How did you feel ? " I ask afterwards, and the man who two minutes before had been crouching in the machine, hardly venturing to touch the controls, replies : " I started nicely ; then came a gust from the right; I moved the rudder, noticed that I pushed it too far, adjusted it, pulled the stick a bit and steered sideways. Then I got ready to land/' It is extremely difficult to convince him that he has done none of these things, though he may have imagined himself doing them. " Have you ever dreamed that you are being pursued ? " I ask him. " You want to run, but you can't. You believe that you are exerting all your powers, but in reality you are doing nothing at all. That's what you and most beginners are like the first time you're in the machine." The next pupil pushes the stick a bit too hard when he starts, and the machine comes down with a bump after a flight of less than twenty feet. " First I saw everything blue around me," says the man, " then it all changed to green, and finally the machine crashed." He at least is honest. The most difficult pupil is the one that starts by doing everything wrong. The machine rears, but instead of pushing the stick forward, he pulls it. The machine continues to rear ; he pulls it further until it is almost standing on its tail. It hangs in the air for a fraction of a second, and then drops earthward like a ripe plum. No great damage is done as the fall is merely a matter of some twelve feet or so, because we always start our beginners on level ground, so that the worst that may happen is a broken wire or two, while man and machine are certain to escape serious injury. " What did I do wrong ? " asks the unlucky fellow. " I meant to push the stick over." He may be one of those persons who cannot grasp the simple action of the control lever, and to such a one you must try to explain matters in some other way. " Imagine that you are in a kayak or some kind of light boat," you tell him. " A high wave surges up before you ; what do you do to balance your boat ? " " I bend forward." " And on the same principle you bend sideways if the boat lists. If you can't learn it any
