To avoid confusion, I shall not use the term “S” turn at all, but only speak of a downhill turn.

Fig. 34.—Downhill stemming turn to left (3, 4, and 5).

The blackened parts are those which should be weighted.

The best way to practise the turn at first is to run, as before, straight downhill in the double stemming position for a few yards, then throw the weight on the left ski as if you meant to turn uphill to the right and stop ([Fig. 34], 1 and 2), but just before the left ski points horizontally across the hill, transfer the weight to the heel of the right foot, and face round to the left a little.

You will find yourself beginning to turn downhill again—the left ski falling a little behind the other as you do so—and by keeping the weight on the right foot you will go round until you face across the slope in the opposite direction ([Fig. 34], 3, 4, and 5), when you can shift the weight to the left foot and reverse the process.

By repeating this you will descend the hill in short zigzags.

The important points are—(1) to hold the stemming position unaltered with the knees straight, the heels of the skis wide apart, and the tips close together; (2) to throw the weight well on to the outer ski; and (3) not to let the inner ski get in front.

The last half of the turn, from the point at which you are facing straight downhill, is, of course, really an uphill one, identical with what you have already learnt, and can be finished at any point in any of the ways already described.
