GENERAL HINTS

Ski-jumping to the ordinarily constituted person who tries it for

the first time is extremely alarming. Although when the whole of the

hillside is of the same steepness he may from the starting-point see

something of the lower part of the slope, the exact spot on which he

will land is nearly always hidden from the jumper until just before he

reaches the edge of the platform, and even from that point it is still

invisible if the platform is built back from the edge of a steep slope.

When the lower part of the jumping-hill is steeper than the upper,

as it nearly always is, the platform, seen from above, appears to be

projecting over the edge of a cliff.

This at first gives all but exceptionally bold spirits an irresistible

desire to shrink back on approaching it, and it usually takes one

some time to overcome this desire, even after realising that there is

practically no danger at all. Even when the jumper feels no fear his

natural disinclination to make his spring until he can see where he

is going to land will for some time tend to make him defer the "Sats"

until too late.

The instinct to shrink back is, at any rate at first, the principal

difficulty in ski-jumping, and I think you will find that the best

way to overcome it is, in a sense, to give way to it--that is, to

start under conditions which are as little alarming as possible and to

increase the difficulty by very slow degrees.

Begin by making very short jumps on a quite moderate slope, no steeper

below than above the platform, which must be quite low and long.

The fact of the slope being a gentle one does actually add to the

difficulty of standing, but only to a very slight extent if the

platform is quite low; and this form of hill is so much the least

alarming, that I advise you to choose it for your first attempts.

Then make the same kind of jump on a fairly steep slope.

Then build your platform, still quite low, rather back from the edge of

as steep a slope as you can find, the slope above it being a moderate

one. Begin here with quite small jumps, and gradually start farther and

farther back until you can make, with fair certainty of standing, as

long a jump as the form of the hill and platform will permit; taking

care, of course, that the lower slope is of ample length, _and that

there is no sudden change of angle where it joins the level_, for this

causes really bad falls.

After this you can make things more difficult for yourself in various

ways, such as increasing the height of the platform, or building it

at the very edge of a steep slope instead of rather back from it, or

making it point upwards so as to form a "squirt jump."

"A squirt jump" on a moderate slope is excellent practice. The

considerable difference in angle between the platform and the

alighting ground makes it necessary for the learner to throw himself

well forward in making the "Sats," and the fact that he drops from a

good height on to comparatively flat ground makes the shock sufficient

to compel him to bend his knees and take the Telemark position on

landing. Only jumps of a few yards should be made in this way, however.

The shock is too great for safety if the drop is a really long one.

On no account allow yourself to forsake easy hills for more difficult

ones until on the former you can make your jumps _in perfect style,

correct to the smallest detail_.

It is only by acquiring an absolutely perfect style that you can make

anything but the smallest and easiest jumps with any certainty of

standing, and for this reason the only way to gain confidence is to

improve your style.

It may be a fine moral discipline to force yourself over jumps of an

alarming size from the very first, but it will not make you a better

jumper; for if you are very nervous you will be able to think of

nothing until the jump is finished, and so will learn nothing and have

no better prospect of standing at the twentieth jump than at the first.

After a course of this it is not unlikely that the last state of your

nerve will be worse than the first.

It is a good thing to jump occasionally on big hills almost from the

first if you can do so without feeling very nervous, but do not give up

small jumps until your style is perfect, otherwise it never will be.

In Norway the style of the jump is considered as important as, if

not more so than, its length. At a competition a jumper receives

marks according to the manner in which he performs each stage of

the jump--the approach, the "Sats," the flight through the air, the

landing, the rest of the run, and the swing at the finish. Under

certain circumstances even a fall is not considered greatly to a

jumper's discredit. If, for instance, a man makes a jump in good style

and is evidently steady on landing, but, after running a few yards,

loses his balance on a bad bit of ground, he may score higher than a

man who jumps rather farther and finishes without falling, but does

so in very bad style. I do not mean to say that merely dribbling over

the edge in a graceful attitude is encouraged, for to jump as hard as

possible is part of good style, and to receive any consideration a

jump must, as to length, be within reasonable distance of the maximum

allowed by the form of the hill and platform.

Those who jump farthest, however, almost invariably jump in the best

style, and a very long standing jump in really bad style is sure to be

a fluke; so that in rewarding the most accurate jumpers the Norwegians

probably reward those who in the aggregate have jumped the greatest

distances, whatever their performance on any single occasion may be.

I agree, however, with Mr. Richardson in thinking that this system is

likely to lead to too much stress being laid on the purely ornamental

side of style, and that on the whole it would be much better to

consider only the length of the jump and whether the jumper stands or

falls on landing. Always bearing in mind, then, that it is only a means

to the end of jumping as far and of landing as steadily as possible,

do your utmost to improve your style, watch for faults, and get other

people to criticise you as well. Check at the outset any tendency to

acquire any of the following bad habits:--

In the crouching position before the "Sats":

Separating your feet or knees; only bending slightly, instead of

crouching quite low.

In the "Sats":

Making a feeble, timid effort, and not straightening out completely,

instead of springing smartly and vigorously to an erect position, with

body and legs in a perfectly straight line.

In the air:

Bending at the hips or knees; separating the skis, not keeping them

parallel and in the same plane; letting their heels drop; not keeping

the feet level; not bringing the knees together before landing.

Landing:

Landing with the skis apart, or edged outwards, or not parallel, or

with one more ahead than the other; letting their heels touch the snow

first; landing with straight legs (or very bent ones); not dropping

into Telemark position.

There is a method of jumping known in Norway as the "traekke op," in

which, during the flight through the air, the feet are drawn up as

close as possible to the body, which is bent forward. This diminishes

the resistance of the air and perhaps slightly increases the length of

the jump, but is considerably more difficult than the upright method,

because it has a greater tendency to make the jumper land leaning

backwards, or with the knees and feet separated so that the skis are

pointed apart, or with the legs so much bent that they are liable to

collapse from the shock.

In Norway this method is generally considered less good style than the

other.

If you wish to try it you had better make the "Sats" in the ordinary

way, straightening out completely before you begin to draw up the legs,

and almost completely again before landing. Be sure also, in lifting

the feet, to raise the toes well in order to avoid any risk of plunging

the points of your skis into the snow on landing.

It is very good practice for the balance to make jumps in this way

when you cross small undulations in the course of a run, or even when

the ground is quite smooth. You will then, of course, have to draw up

your feet the moment you leave the ground. Be careful, by holding your

_knees_ together, to keep your skis from pointing outwards as you land.

An expert when running fast can in this way jump a low fence or, to be

precise, an obstacle 2 feet or so high.

In spite of all that I have said about the necessity for taking it

gradually, and keeping off big hills at first, you need not be afraid

of hurting yourself much, no matter how far you may jump, provided the

hill and platform be properly arranged, for in that case an accident

is almost impossible. You are far more likely to meet with one when

running at a comparatively low speed on tour, if the snow is soft and

deep.

To be able to jump even moderately well will enormously improve your

running generally, and will give you a confidence and dash that can

hardly be acquired in any other way.

It is an excellent plan for the beginner to practise all the motions

of jumping while running down a slope, without any platform, and at

first without even a change of gradient. Make a mark on the ground;

run towards it, crouching; make the "Sats" as you reach it, springing

into the air if possible; drop into Telemark position, and straighten

up again. Practise this until on a slope where there is a slight change

of gradient you can make a jump of 3 or 4 yards steadily, and you will

find things come much easier when you try from a platform.

Finally, let me remind you of the childish plan that I have already

advocated, of pretending that you want to go faster than you are

actually moving. You can now pretend that you want to stay in the air

as long as possible--unless you really want to, which is unlikely at

first.

The man who wants to make a long jump is much more likely to stand than

the one who merely wants not to fall.

_Short Directions for the Jump._--Run in normal position until within

about 15 yards of the platform's edge (not so close if running very

fast), then bring your feet level and, _keeping your knees pressed

together_ and well forwards, crouch down as low as possible. When the

hands can touch the ankles draw them right back.

Just before reaching the edge of the platform make the "Sats" by either

of the following methods:--

1. Without raising the heels or moving the feet or legs below the

knees, swing your arms forward and upward and straighten yourself

smartly until your body and thighs are in a line with the lower part

of the legs. You will then, if you have moved from the knees only, be

leaning well forward.

2. Swinging the arms as before, spring vigorously almost straight

upwards from the platform, giving the body a slight forward tilting

motion as you do so, and straightening out completely from head to

foot, but this time raising the heels and finishing the spring from the

toes.

On completing the "Sats," hold the erect position during the flight

through the air, keeping the feet level and close together and the skis

parallel to each other and to the slope below.

Just before landing press the knees together, and, as you feel your

skis touch the snow, but not until then, drop into Telemark position.

The moment you feel steady straighten up again, finish your run in the

normal position, and swing or jump round.
