Holiday gift from my daughter. 1950 publish date. Lots of good stuff.
“The technique of the turn on a single slalom ski is quite different. As you approach the turn, straighten both knees and transfer your weight so that about half of it is on the foot in the rear binding. Then, when you want to turn abruptly, lean to the side and even further backward. Your rear foot can be used to bank the ski more or less, as required.”
