This almost convinced me I could learn to ski properly from a book, for the collaboration provides both the expert and technical factual data and the presentation by one who defines himself as a ""tyro"" near enough to the problems of learning to know what is difficult, what must be explained in primer terms. He has made his text not only clear from the ""how-to"" angle, but entertaining reading. The method chosen is the Arlberg Method, which Mr. Spectorsky feels is basically sound, can be learned at slow speed and applied at high, and is especially adapted to the open slope downhill skiing which is most generally popular in this country. There is advice on how to use the book, on equipment and clothing. Every movement described is illustrated by photographs by Lloyd Arnold and drawings by S. Fleishman. Personally, I found the diagrams a little difficult to follow, but maybe it is like knitting instructions; when you start following them, the difficulties straighton themselves out.
