THE STEMMING TURN

I must here apologise for the extreme ambiguity of ski-ing terminology,

which, however, as I did not invent it, I have not the moral courage to

try to improve. The term "stemming" may be used in several different

senses. In its narrowest sense it means holding the skis in the [V]

position and braking with _one_ of them. More broadly it means braking

with _both_ in the [V] position. It also means braking with the skis in

Telemark position. In fact in its broadest sense it means any sort of

braking except side-slipping with the skis parallel.

In this sense almost any method of turning on skis might, as we shall

see later, be called a "stemming" turn. The expression "stemming turn,"

however, is generally used in a special sense to denote a turn during

which the skis are held in the [V] position with the feet nearly level.

By means of a "stemming turn" you can, as you already know, turn

_uphill_ or stop when traversing; you can also do so from a direct

descent. You can, moreover, turn _downhill_ from a traverse until

you face in the opposite direction and run off on a new tack.

This turn is effected by putting the skis in a more or less wide

[V] position, and either simultaneously or immediately afterwards

_weighting_ and slightly advancing the one that is to be outermost

in turning. To show how in this as in all turns the various factors

of side-slipping, with the weight variously distributed, combined

steering action of both skis, edging, &c., come into play according

to circumstances, it will be necessary to describe in detail the two

different uses of the turn.

For practising these turns find a moderate slope and snow in which

it is easy to stem when running straight downhill; a much trodden

practice-ground is the very thing.

_Uphill Turn to the Left._--You already know how to turn uphill from

a traverse by stemming; the following way of doing it is slightly

simpler. Traverse to the left at an easy gradient in normal position,

weight on right foot. When you want to turn, draw the upper ski a

little to the rear (Fig. 31, _1_) and then push the heels wide apart,

straightening both legs and putting all the weight on the lower heel

(Fig. 31, _2_ and _3_). As the lower ski begins to turn uphill, bring

the other one smartly to its side again in normal position.

This is much the same thing as stopping when stemming with the lower

ski, as described above (page 121), but is rather simpler, for the

uncomfortable crouching position necessary when stemming with the lower

ski is avoided, there is no shifting of the weight from one ski to the

other, and the preparatory movement of drawing back the upper ski can

perfectly well be made simultaneously with the actual turn.

[Illustration: FIG. 31.--Uphill stemming turn to left. The blackened

parts are those which should be weighted.]

To make an uphill stemming turn when running across a slope in normal

position is rather a clumsy process, and it is quite unnecessary to

spend much time in practising it, for an uphill turn from a traverse

can be made more easily and effectively by the Christiania swing, in

the way already explained, or the Telemark, which will be described

later. Just make sure, however, that you _can_ turn uphill in this

way from a traverse in either direction, and then try the turn from a

direct descent, as follows.

Run straight downhill in the stemming position with the weight equally

on both skis and the feet as wide apart as possible, taking care that

the legs are quite straight at the knee, and rigid (Fig. 32, _1_).

[Illustration: FIG. 32.--Uphill stemming turn to left.]

In order to turn to the left (most people find it easiest to learn to

turn to this side first) you have simply to throw all the weight on to

the heel of the right foot and turn the body to face the point of the

right ski. You will begin to turn to the left, and as you do so the

left foot will involuntarily fall slightly to the rear (_2_), when the

steering action due to the relative position of the skis will help the

turn.

If you keep all the weight on the heel of the right foot you will go on

turning until the right ski points slightly uphill, when you will come

to a standstill (_3_). As you do so, be sure to bring the inner ski

quickly to the normal position.

This is extremely simple, and, if you keep both legs quite straight and

the feet wide apart, you can hardly fail to do it correctly.

The mistake you are most likely to make is that of letting the left

knee bend as you begin to come round. If it does so the left ski will

get on its outside edge, and, instead of continuing to skid round, will

only run in the direction in which it is pointing, so that if it does

not run across the other (Plate XXV.), and throw you down,[8] you will

find yourself running obliquely across the slope, stemming with the

right ski only instead of turning uphill and stopping.

It is not sufficient, however, to keep the inner leg straight, for

unless at the same time you keep nearly all weight off it, either the

left ski will get in front and you will begin to face downhill again,

or it will get too much on to its inside edge, and will at least

prevent you from finishing the turn, even if it does not trip you up.

As soon as you can turn to the left in this way, learn to turn to the

right, of course substituting "right" for "left" and "left" for "right"

in the directions.

If, while running straight downhill, you turn and come to a standstill

in the way I have described, you will, when you have stopped, find

yourself a certain distance to one side or the other of your original

course.

This may not always be convenient; you may, for instance, want to stop

while running down an icy road, fenced on each side, and so narrow that

you have only just room enough to stem, and would run into the fence if

you swung to one side in stopping.

In a case of this sort you can turn suddenly and stop in your tracks in

the following way:--

Suppose you are running straight downhill in the double-stemming

position; when you want to stop, give a vigorous push with one

foot--say the left--and so throw all your weight _suddenly_ right

outwards on to the heel of the right foot, turning the body quickly

well round to the left as you do so. If this is done with force and

decision the right ski skids round quickly to a horizontal position,

and as it does so, the left ski comes into the air, is lifted smartly

round, and brought down parallel with and close to the other one. You

then find yourself at a standstill, facing to the left across your

original track, but without having moved to one side of it (Fig. 33).

Just at first you may fail to do this properly through giving a timid,

jerky push with the left foot instead of a steady thrust. This will

prevent your weight from going sufficiently outwards over the right

ski, and the left ski will come to the snow again before you have had

time to lift it round to the side of the other one and before that one

has had time to skid round to right angles with your course. After a

very few trials, however, you should be able to do it correctly, and

you will then find that no great force is necessary, and that the

movement need not even be made particularly quickly provided it be done

with a free swing. In order to give the push you must, of course, bend

the inside knee slightly.

[Illustration: FIG. 33.--Uphill stemming turn to left. The blackened

parts are those which should be weighted.]

Provided the inner ski is brought _parallel_ to the outer one, it

does not matter if it comes to the snow again _before_ the latter has

skidded round to right angles, for then the turn can be finished with

both skis side-slipping together--that is to say, the turn can begin as

a stemming turn and finish as a Christiania, a most useful combination

which is beginning to be known by the dreadful name "Stemmiania," which

I only quote in order to record my dislike for it.

This way of making the turn is practically instantaneous, and is so

convenient that when you have once learnt it you will hardly ever use

the one I described first. By means of it you can stop suddenly when

moving at a very fair rate, especially if you stem hard with both skis

well edged inwards just before making the turn.

Practise this movement without skis at first, and then at a standstill

with skis, on the most slippery snow you can find, trying to make the

outer ski spin right round to right angles.

These uphill stemming turns enable you to stop yourself wherever

the quality of the snow and the gradient allow you to hold the

double-stemming position while running straight downhill. It is no use

attempting to make them on very steep slopes or in snow into which

the skis sink deeply; in either of these cases you will have to stop

yourself by means of the Telemark or Christiania swings, described

later.

I need hardly say that if you merely wish to alter your course and not

to stop yourself, you can finish the turn at any point. You either

wait until the outer, weighted ski is pointing in the direction you

want to go, and then bring the other ski parallel to it in the normal

position and run on at full speed; or, if you still wish to brake, you

turn rather farther until the inner ski is in line with your intended

course, and then shift the weight partly or entirely to that one and

run on stemming.

_Downhill Turn to the Left._--A turn made in a downward direction in

order to join one tack to another when descending a hill in zigzags is

often called an "S" turn, on account of the shape of the track left by

a number of these turns made in alternate directions (Plates XXVI.,

XXXIII., XLII.).

Any downhill turn, therefore, whether made by the stemming turn or

by any other means, can be called an "S" turn. A good many people,

however, having never seen a downhill turn made by any other means

than the stemming turn--or at least the awkward manoeuvre which the

average runner imagines to be the stemming turn--believe "S" turn

and stemming turn to be synonymous.

As will be seen later on, a downhill or "S" turn can quite well be

made by means of the Telemark or Christiania swings, the "S" having no

reference whatever to stemming.

To avoid confusion, I shall not use the term "S" turn at all, but only

speak of a downhill turn.

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.

[Illustration: FIG. 34.--Downhill stemming turn to left (3, 4, and 5).

The blackened parts are those which should be weighted.]

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.

You can start a downhill turn, like an uphill one, from the normal

position while running across a slope, and under these conditions the

turn is, as in the case of the uphill one, rather less easy; this time,

however, it is extremely important to be able to do it, for this is by

far the most useful application of the stemming turn, and you can in

this way, provided the snow be suitable, join one tack to another on

a slope of any steepness, where it would be impossible to run straight

downhill in double stemming position.

Suppose you wish to start a downhill turn to the left while running at

a gentle gradient across a slope in the normal position (_i.e._ with

the weight on the left foot and the right foot in front), the first

thing to do is to turn the right knee and ankle inwards so as to lift

the outer edge of the ski as much as possible. Then, keeping the point

of the right ski ahead of the other, push its heel uphill and out to

the position of _2_, Fig. 35, B, at the same time weighting the _toe_

of the _left_ foot and slightly flattening that ski, which will then

begin to point downwards and give the other more room to turn. As

they turn downwards push their heels wide apart and throw your weight

quickly outwards so that a final thrust of the left leg sends it _full

on to the right heel_ just as you face straight downhill. Almost

simultaneously lift the left ski round to the side of the other and

finish the turn with the skis parallel.

As you lift the inner ski turn (not _lean_) the body inwards just

enough to face squarely towards the point of the outer ski.

If you turn slowly there will be an interval between the pushing round

of the outer ski and the final thrust of the inner leg during which the

skis will be equally weighted. If you turn sharply while running fast

the checking of the outer ski's speed as it comes broadside on will

throw the weight on it at once and lift the inner ski without an effort.

[Illustration: FIG. 35.--Downhill stemming turn to left (two methods).

The blackened parts are those which should be weighted.]

It is also possible to make the turn by putting the weight on the outer

ski _before_ it begins to stem at all, and making it turn downhill by

pressing on the toe (as in Fig. 35, A). I used to think this method the

easier of the two, but have changed my mind about it, and can only

apologise for leading people astray.

Up to this point you have been practising on moderate slopes only, but

it is on steep slopes that you will generally have to use the downhill

stemming turn, and it is on steep slopes that you should practise it

the instant that you can do it neatly on a gentle one.

You will then find a difficulty that has probably not bothered you much

so far. On a steep slope, as you begin to turn downhill, the increase

of speed is sudden and considerable, and if you do not compensate for

this by throwing the weight more and more forwards, the skis will shoot

from under you, and you will sit down.

Don't, however, begin leaning downhill _too soon, while still facing

across the slope_, for that will throw the weight on to the inside

(lower) ski. Simply lean as far forwards over the front of your skis as

possible, so that as they turn downhill your weight will be well over

them.

The difficulty of leaning forward sufficiently on a steep slope is

partly due to the tendency to stand with the weight vertically above

the feet, as one would do when _walking_ downhill. The very best plan

for overcoming this difficulty, and one which will make it infinitely

easier for you to perform the turn quickly and correctly, is to keep

your eyes fixed on the ground at your feet while you are turning, and

to imagine that it is almost or quite level. You will then naturally

hold yourself at right angles to the slope no matter how steep that may

be.

You will find this downhill turn of very little practical use on a

steep slope until you can make it quite shortly and sharply; for if you

make a long curve, the pace increases so much in the middle of it that

you are almost sure to lose control, and fail to finish the turn, even

if you do not fall down.

The reason why to lift round the inner ski at the middle of the turn is

safer than to keep it on the snow throughout is because the curve is

thus considerably shortened.

The act of suddenly throwing yourself very far forward over the front

of your skis as you face downhill will make them hang back a little

for an instant--all the more so for the fact that at this point the

stemming action of both is at its maximum--and at this moment it is

easy to give a push with, and then to lift round, the inner ski.

Be careful, in lifting the ski round, to bring it down again exactly

parallel to the outer ski; for the inner one, if it comes down pointing

_towards_ the outer one, will instantly run across it and upset you;

while if pointing _away_, it will run uphill and draw your feet apart

with a jerk that will probably have the same result.

Although, as I have said, you should turn the body a little in

throwing the weight outwards, it is no use attempting to lean or swing

it the way you _want_ to go. You must simply throw it forwards and

_outwards_--that is, rather _away_ from where you want to go. If you

lean the way you want to go you will simply put weight on the inner

ski, which will then either trip you up or make you run away straight

downhill instead of finishing the turn. Indeed, paradoxical as it

may sound, you should, in a sense, try _not_ to turn; manoeuvre your

skis as I have directed, and _try to keep a straight course, turning

sideways as you do so_, and you will probably come round without

difficulty.

The faster you are running at the moment of beginning the turn, the

more difficulty you will at first have in making it.

You had better, therefore, when learning it, run at a gradient which

will only just allow you to keep moving smoothly (I am speaking of

the gradient of your course across the slope, _not_ of the gradient of

the slope itself), otherwise, before beginning the turn, you may be

inclined to stem with the lower ski in order to check the pace, and,

when the lower ski is put in stemming position before the other is

pushed round, there is a tendency for the weight to get too far back

in the effort of starting the turn, which then misses fire. If you are

bound to slow up before you begin the turn, do so by side-slipping with

both skis and turning a little uphill (_i.e._ make a slight Christiania

swing) as described in the last section, p. 131.

On an icy and steep slope it is, of course, especially necessary to

make the turn very sharply if you are not to lose control in the middle

of it. You can do this by running very slowly before turning, and then

quickly putting the upper ski far round, and simultaneously weighting

it by means of what is practically a _jump_ from the other ski, which

comes into the air almost before the first is weighted, and is brought

down parallel with it almost instantly. This is well worth practising

assiduously, for it makes all the difference to the safety of a turn on

very steep and icy ground.

Do not be contented until you can make a short, sharp turn (both to

right and left, of course) with perfect steadiness, on the steepest

slope you can find. For although on steep slopes a Telemark or

Christiania swing is the best way of making an _uphill_ turn, there is

no means so reliable as the stemming turn for turning _downhill_, no

matter how steep the slope, _provided the snow is hard, or that, if

soft, it is shallow_. It is almost useless, though, to attempt it in

deep soft snow. At the best you will probably only get halfway round

with an uncomfortable effort, and then the inner ski will be forced

back, and come round after the other in Telemark position, in which, as

you will find later, it might just as well have started.

At the worst you may be tempted to drag yourself round with the stick

in the position shown in the photograph (Plate XXVIII.).

This position, which, I hope, is becoming less fashionable, is the

very essence of incorrectness and awkwardness, and is an infallible

sign either of poor nerve or of bad teaching. Here the weight falls

principally on the inside ski and the stick, instead of entirely on

the outer ski, while the skis are held parallel, or nearly so, instead

of in the [V] position. The general position is a crouching one with

the knees bent, instead of an erect one with straight and rigid legs;

except for a feeble stemming action of the outer ski, which is too much

edged, the turning effect is entirely due to the drag of the stick.

Those who make use of this method generally refer to it as a stemming

turn, "S" turn, or Alpine curve, using either of these terms in

contradistinction to the terms "Telemark" and "Christiania," evidently

under the impression that an "S" curve can only be made by stemming,

and that by means of the Telemark or Christiania it is only possible

to turn uphill and stop. The only correct title for this manoeuvre is

"stick turn."

When I say that this method is awkward and incorrect, I do not merely

mean that it is ugly, for I suppose that to the unsophisticated eye its

attitude is no more ugly than the exaggerated straddle of the correct

stemming position. There are two strong reasons for considering it

execrable in style and utterly to be avoided.

In the first place it is a waste of energy, because it takes a

considerable muscular effort to make a turn in this way, even when

the snow is easy, and an exhausting one when it is not; while by

substituting correct methods one can always turn without the smallest

strain. The second objection to it is that it is inefficient, for by

turning in this way it is impossible to make a short curve, especially

in deep soft snow; and until a runner can turn sharply in snow of any

quality and on a slope of any steepness (I do not say at any speed), he

by no means can be said to have proper control of his skis. I do not

for a moment deny that it is the easiest way of turning, in the sense

that it is the one requiring the least skill. But any one who knows

what can be done by correct methods, who has ordinary nerve, and who

does not look on ski-running solely as a means of locomotion, for which

a technique demanding the minimum of skill is the one to be preferred,

will shun the "stick turn" as he would the pestilence.

Finally, let me remind you once more that in stemming--and this holds

equally good whether you are turning or going straight ahead--the skis

should never be quite flat; their outer edges must be lifted a little

even when the snow is easy, rather more so when it is not (see p. 83).

To be quite accurate I ought to have said the skis must not be _kept_

flat, for obviously they must during a downhill turn each pass through

the flat position, since their edging, on the tack before the turn, is

the reverse of what it is on the tack that follows it. This change of

edge, as a matter of fact, constitutes one of the difficulties of the

turn. The outer ski makes the change easily enough, for the outer ankle

(which is bent inwards in order to start the turn) does not have to

alter its position while the change of edge takes place. But the inner

ski, if kept on the snow throughout the turn, is by no means easy to

manage at the moment that the change has to be made. This ski remains

on its inside edge until nearly the end of the turn, and if allowed to

remain so for a moment too long is very apt to catch on this edge and

run across the other or refuse to come round, especially on a steep

slope, if (as he should have done) the runner has made a very wide

straddle when facing straight downhill.

This difficulty is entirely avoided when the turn is finished by the

_lifting_ of the inner ski (the change of edge then taking place, so to

speak, in the air). Indeed, although this lifting of the ski may sound

somewhat acrobatic to any one who has not tried it, it is really quite

the reverse. It needs far less adroitness than does a neat and steady

finish of the turn with the ski kept on the snow, and is, in fact, not

only the quicker and more effective, but also considerably the easier

and safer of the two methods.

The runner can only make a true stemming turn when going at a moderate

pace. By finishing it as a Christiania, however, he can turn either

uphill or downhill when going much faster. In fact the sooner the skis

are brought parallel, the greater the pace at which the turn can be

started; at very high speeds only a trifling preliminary stem being

either necessary or safe.

_Short Directions for a Downhill Stemming Turn to the Left_

From normal running position, right foot leading, left weighted.

Bending and turning inwards right knee, ankle, and foot, push heel

of right ski outwards and forwards to the widest possible stemming

position--its tip close to but ahead of the other's--at the same time

slightly flattening the _left_ ski and pressing on its _toe_. As the

skis turn downwards push their heels wide apart, quickly shift your

weight forwards and outwards, and, with a push from the inner ski,

throw it _full on the right heel_ as you face straight downhill--at the

same time lifting the left ski quickly round to the side of the other

and finishing the turn with the skis parallel.

When moving slowly this is to be done in two motions; when moving fast,

in one continuous one.

Fix the eyes on the tips of the skis and try to lean in that direction

only, not inwards.

_N.B._--The latter half of this turn is, of course, really an uphill

one, separate directions for which are therefore unnecessary.
