n a golf ball over thirty yards farther than the limit which his learned parent had shown to be obtainable. Naturally, Professor Tait had to reconsider his statements, and he then arrived at the conclusion that there must have been in the drive of his son, which had upset his calculations, some force which he had not taken into consideration. He soon came to the conclusion that this was back-spin, and he dealt with this matter of back-spin, which is a matter of extreme importance to golf, in a mos

This is more particularly so when it is a matter of back-spin, but it is equally true of the pulled ball or the sliced ball. Both of these proceed for a considerable distance bef

In experimenting with such a stroke as this, and in such a manner as this, it should be evident that there should have been no restriction whatever as to the player's trajectory.

It may indeed be that Professor Thomson has been unfortunate enough only to have read articles wherein an erroneous explanation of the well-known phenomena of the flight of the ball is given. Be that as it may, there can be no doubt that the explanation which has been given of the causes of swerve has been adequate and accurate, and

practical point of view, to send a golf ball away without spin from the face of a driver as it is from the pouch of a catapult. The catapult is a machine, and it is a certainty that it can be made to propel a golf ball without any initial spin whatever. A mac

In fact, even if a golf ball were driven by a machine which did not impart to it any initial spin, it is almost a certainty that that ball would not have proceeded far before it had acquired sufficient motion to justify one in technically calling it sp

This, obviously, is most unscientific. If the nose of the ball is the point that is farthest in front, I cannot say too emphatically that

is matter, and it is one which is calculated to mislead people who would otherwise understand the matter quite clearly, so we shall drop Professor Thomson's idea of giving the

n they are on one side of the boat they have to face the wind, on the other side they have the wind at their backs. Now, when they face the wind, the pressure of the wind against them is greater than if they were at rest, and this increased pressure is exerted in all directions and so acts against the part of the ship adjacent to the deck; when they are moving with their

passengers circulating round the deck of a ship, and his golf ball would receive a serious blow. In stating a matter which is of sufficient importance to be dealt with before such a learned body as the Royal Institution of Great Britain, it is well to be accurate. If Professor Thomson had

question of impact with the ball, clouded the issue. At page 12 of his remarkable lecture he says: "So far I have been considering under-spin. Let us now illustrate slicing and pulling; in t

ectric battery which causes negatively electrified particles to fly off the barium and travel down the glass tube in which the platinum strip is

ce of the club was vertical. Now this does not happen with the slice at golf, for the very good reason that if one so applied one's club, the ball would not rise from the earth. The club which produces the slice is always lofted in a greater or less degree, and quite often the natural loft is increased by the player designedly laying the face back during the st

s the axis of spin will be inclined backward. It seems likely, also, that as the axis of spin is inclined backward and the ball is rising, there will be some additional friction at the bottom of it which would not be there in the case o

leaves the axis of rotation inclined backward, but sometimes inclined also slightly away from the player, but it is obvious that even if the ball had, as Professor Thomson thinks it has, rotation about a vertical axis, which is the rotation of a top, such rotation would, on landing, tend to prevent the ball running, for, as is well known, every spinning thing strives hard to remain in the plane of its rotation, but the slice is more obstinate still th

arts to the ball a spin around an axis which lies inward towards the player. This means that the pull goes away to the right, and then swerves back again towards the middle of the course if properly played, and

ry boy who has played with such a top will be familiar with the fact that when the spin is dying away from the top, it rolls about un

the earth, but from this very simple explanation it will be perfectly obvious to anyone who gives the matter the least consideration that not only is the axis of

I cannot help thinking that Professor Thomson in saying that in such a ca

inety per cent of cases, the club is not moving in a horizontal direction-in fact, it would be hardly too much to say that it never moves in a horizontal direction. It is nearly always moving either upwards or downwards in a curve at the moment it strikes the b

tter of that many people who are far beyond beginners, to trust the loft of the club to raise t

cing the back-spin which so materially assists the length of the carry. There can, of course, be no doubt that loft does assist a person in producing this back-spin, or, as Professor Thomson calls it, under-spin, but to nothing like the extent which is imagined by the worthy Professor. The beneficial back-spin of golf is obtained by striking the golf ball before the head of the club has reached the lowest point in its s

m the loft of the club, shows us a club face with a loft much greater than that of a niblick, and proceeds to demonstrate from this loft, which it is unn

ain how the beneficial back-spin of golf is obtained. Such a club as he shows might be useful for getting out of a bunker, but it certainly would be of no use whatever in practical golf for driving. As every golfer knows, the face of the driver is, comparatively speaking, very upright, and firing a ball at a wall built a

l stroke, and that is the stymie stroke introduced into the game by me, and which I have hereinbefore fully described. This stroke shows us conclusively how the power goes mostly into elevation instead of into propulsion. It is an absolute answer, if on

lub were at rest and the ball were shot against it horizontally from left to right. Evidently, however, in this case the ball would tend to roll up the face, and would t

o obtain the beneficial back-spin of golf with a club having a vertical face, and being at the moment of impact in a vertical plane, but in order to do this it would be necessar

understand that by using the high tee for a low ball they are enabled to cut down beyond the ball more than they could do if the ball were lying on the ear

ng blow, there is in the blow much more of the forward motion than the downward, so that all the ordinary principles with regard to getting the ball up into the air, apply with equal force to this stroke as to any other, and it is a matter of prime importance that the ball must be struck below the centre of its mass-that the loft of the club must

k, it leaves the club with a very great amount of back-spin. The hands are always forward of the ball at the moment of impact in this stroke when it is properly played. It stands to reason that this, to a certain extent, decreases the loft of the club with which the stroke is played. The result is that the ball goes away on the first portion

on the air, it is lessened by the fact that the upper portion of the ball is revolving or spinning backwardly towards the player. The result of this is that the ball is g

he ball will run along the course. It stands to reason that it would require an enormous amount of back-spin to stay with the ball during the period of its low flight, to lift the ball then to the highest point in its trajectory near the end of its carry, to stay with it still in its descent, and then to be strong enough to resist the shock of landing so as to check the run of the ball. The

the line of flight. Both of these, I may say, are absolutely impossible in golf. He shows a slice in Fig. 29 which would be much more likely to result in a

the moment of impact, but as I have shown the slice is not produced by the arms being pulled in at the moment of impact. It is produced by the club head travelling across the ball at an angle to the intended line of flight of the ball. Professor Thomson shows the slice in this case by diagram, and correctly, bu

oposition is so simple that although I give his indicating letters

as would be produced if the arms were pulled in at the end of the stroke, the effect of the impact now will be the same as if the club were at rest and the ball projected along R S, the ball

but we need not waste any further time going into that matter. We can

r a certain distance across the direct line of flight to the hole, and during the time that they are thus travelling together the club is imparting spin to the ball and influencing its direction, so that instead of th

correct from a golfing point of view. It is quite evident that before we could accept as authoritative the explanations which have been

trated-in a leader, invited Professor Thomson to make good his assertions, but he has not been able to do so. One can understand fallacious matter being published under the names of professional golfers when one knows quite well that the ma

so far as regards obtaining extra distance by driving a low ball with back-spin, whose properties I have already fully described, there is nothing whatever

on the flight of the ball in the case of many other shots, and the peculiarities of different trajectories can generally be traced to this cause after a very little t

It is quite evident to me that Braid is falling into the same error as that which was originally made

great difference in the comparative trajectories of the two balls. In the case of the short one there is no resistance to gravity, and consequently, in order to get any sort of flight at all, the ball must be directed upwards when it is hit from the tee, or, to use a scientific term, there must be "initial elevation." This may be only very slight, but it is quite distinguishable, and in fact a player, who is only at the beginning of his practice, and has little knowledge of the principles of the game,

solutely a matter of science, we do not expect such loose statements as these. I should probably have passed this remark, but for the fact that it is emphasised by the statement that in order to get any sort of flight at all the ball must be directed upwards when it is hit from the tee

s is quite wrong, for the blow should be at least in a horizontal direction, which practically it never is, and preferably in the line of the arc formed by the club head in its travel through the air on its downward path. The latter case, of course, would produce back-spin, and a considerable amount of it. The former would probably produce slight back-spin, but a v

t is evident that Professor Tait was under the impression, in which, as I have stated before and now emphasise, he has been followed by Professor Sir J. J. Thomson, that the beneficial back-spin in golf is obtained by the loft of the club. There can be no doubt whatever that if a golf ball were struck a blow by a golf club having any considerable degree of loft and proceeding at the moment of impact in a straight line, the result would be to impart some degree of

tring being just below the middle of the ball, so that when it was let go it would impart a certain amount of under-spin to it. When he shot the ball in this way he made it fly straight to a mark that was thirty yard

We can then proceed to notice the really important remark made that "the amount of beneficial spin is seriously diminished by even a trifling upward concavity of the path of the head during the ten-thousandth of a second occupied by the blow." It seems to me that this last statement is absolutely accurate, and it is the thing which I have always contend

ave a delusion to the effect that the ball is at its highest point in the middle of its flight-that is to say, they think that just about half-way between the point from which it was hit and the point at which it will touch the ground again, the ball is at its highest, and after that commences to fall again. In this belief when they have, say, a 140 yards' carry to make, they will reckon that their ball must then be coming down very fast towards the turf, having been at its highest, some 50 or 60 yards before. They may

back-spin, but in the case quoted by Braid there is nothing whatever to show that the ball has been played in such a mann

cont

that it begins to fall rapidly. This is chiefly the result of the under-spin which is given to it when it is struck by the driver in the proper way, and it shows the importance of under-spin to the golfer, for if there were none, then all our courses would have to be shortened, hazards brought closer to the tee, and the pr

a considerable number of diagrams to show that too much back-spin is bad in the drive, but as I have already pointed out, although this is very well in mere theory, it does not work out in the slightest degree in golf. It is easy to take light balloons and give them back-spin and show that it influences their trajectories to such an extent that they will go behin

proc

or too little according to results, and knowing also that in either case excess or otherwise was due to faulty stance or swing-most frequently this-or both. In the present case of this high trajectory,

ent it left the face of the club, so that any attempt whatever on his part to measure the respective rates of spin of the different flight of these balls must be received with very great caution. As a matter of fact the rate of spin of the golf ball at the moment it leaves the club in a well-played drive with back-spin would be immeasurably fas

carcely theoretically possible in golf, and it is practically impossible. I will give an example taken from practical golf which wi

velop that slice in a pronounced manner at, say, half to two-thirds of its carry, which is quite bad enough for a slice. We frequently see in such a case, particularly on a windy day, and even on a still one, the great power which the spin has to deflect the ball from the line to the hole. It must be remembered that in this curve the spin is assisted by gravity-the ball

the slice could be turned upwards there would be no possibility whatever of the ball showing such a thing as a curl backwards towards the hole, which is shown by Professor Tait and, following him, by Professor Thomson. This is clearly so in any slice which is not an extremely exagge

case of the shorter shots with iron clubs, as may be understood after a very little consideration of the circumstances. It is the excessive under-spin that is given to the ball by the angle at which the face of the club is l

bit of "upward concavity" which Professor Tait says, and truly says, is the enemy of back-spin. The fact is that very little under-spin, or, as I always prefer to call it, back-spin, is obtained from the loft of the club unless the blow is delivered as the club is travelling downward. That is the whole essence of the secret of back-spin, but it is not mentioned by Professors Tait or Thomson, or by James Braid. Any attempt whatever to obtain back-spin from

e a glimmering of

ems to be a great advantage of having the faces of iron clubs grooved or dotted that it helps the club to grasp the ball thoroughly while

much a club were laid back it would be impossible to play these shots properly if no under-spin were given to the ball," thus stating explicitly that something more remains to be done

to in this chapter on the science of the stroke. Spe

ime and space of impact are so short that follow-through is of no real account, after all, in the making of the drive. When the follow-through is properly performed it shows that the work was properly done during that half an inch of the swing that was all-important. If the follow-through were short and wrong it would indicate that the work during the impact was wrong too. What it comes to is this, that it is impossible for any man to swing his club round with so much force and regulate exactly what he will do, and be conscious of the fact that he is doing it as he regulated, dur

o consciously perform anything which will affect the flight of the golf ball during impact. Braid has insisted upon this in other places, and it should quite settle any idea which many people have, of juggling with the golf ball d

to here specifically is in connection wi

low-through. He knows from instruction and experience that if all these things are properly done the ball will go off well; and what it amounts to is that th

er's mind at all is that which leads up to impact, for it is obvious that if that has been correctly performed, one need not trouble much about the follow-through, as that will come quite naturally. Also we will observe that Braid says here "control being exercised over each." This, of course, includes the follow-through over which Braid now speaks of exercising control, but it will be fresh in our min

However, a ball that ducks for this reason nevertheless gets some benefit from this over-spin when it does come down, for the spin acts in just the same way as "top" does in the case of a billiard stroke, that is to say, it makes the ball run more.
