It is possible on a gentle slope, if the snow is shallow, to use the skis like skates, striking out with each alternately.

This needs little explanation. You have merely, while running straight downhill, to lift one ski—say, the right—and put it down again pointing outwards from the other at a widish angle, their heels being close together.

The moment the right ski touches the snow, give a vigorous push backwards and to the left with the left ski, at the same time throwing the weight of the body well forwards and to the right over the right foot. While sliding on the right ski, bring the left forward and hold it close to the other, but clear of the snow. You are then ready to make a fresh stroke by putting down the left ski and pushing with the right.

A series of such movements leaves a track as in [Fig. 43], a.

You will find it difficult at first to throw the weight sufficiently forward and outward at each stroke, especially if, instead of putting down the ski on which you are about to slide exactly level with the other, as you should do ([Fig. 43], b), you put it farther forward (c). This difficulty will cause each stroke to become shorter and shorter until it is impossible to continue the movement.

Fig. 43.

In practising, hold the ski which is off the snow parallel with and close to the other one until you are ready to make the next stroke, and slide on each foot at least far enough to make sure that your balance is perfectly steady on it.

It has already been explained how, by striking out to one side only, one can change one’s direction—for, of course, the action of stepping round is precisely the same as that of skating—and how one can in this way steer or stop oneself in breakable crust.
