We have so far only been considering the effect of the spinning of the ball in the case of long shots with wooden clubs. As a matter of fact, and as suggested at the outset, it has also very great influence on the play in the 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 laid back, and the peculiar way in which the stroke is played, that make the ball rise so quickly and so high in the case of a short pitched approach, and then make it stop comparatively dead when it comes to the ground again.

It is obvious here that Braid is under the impression that the loft of the club is largely responsible for the back-spin in the approach shots, but this is quite an error, for not one player in a hundred does apply back-spin to his lofted approaches unless he has been specially taught how to do it, for, curiously enough, the more lofted the club is, the greater chance is there that the player will at the moment of impact impart into his stroke that little 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 the loft of the club will be practically useless. It must be obtained by the method of playing the shot, and the only way to obtain it effectually is to hit the ball before the club has arrived at the lowest point in its swing. By this means, and this means alone, is it possible to obtain the beneficial back-spin of golf, and I cannot say too often or too emphatically that anyone who trusts to the loft of the club to produce back-spin will be disappointed.

Braid seems to have a glimmering of this, for he says:

However much a club were laid back it would be impossible to play these shots properly if no under-spin were given to the ball, and it seems 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 this under-spin is being imparted to it, so that the full amount is given to it, and none is wasted through the ball slipping on the face.

This is unquestionably sound mechanics. But even here, although Braid is so close to the heart of the matter—although he says, as I have shown repeatedly in many places, that "however 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 produce back-spin than merely to hit the ball with a lofted club,—he does not get really to the essence of the stroke and show that it must be played by the club as it is descending.

There is a very important matter which Braid refers to in this chapter on the science of the stroke. Speaking of the follow-through and the impact, he says:

One or two other calculations that were made by Professor Tait may be briefly mentioned at the close of this chapter, each of them seeming to convey an idea to the golfer. The first is, that owing to the speed at which the ball leaves the club, the total length of time during which ball and club are in contact with each other is between one five thousandth and one ten thousandth of a second, and the total length of that part of the swing when the two are together—the length of impact—is half an inch. It has been pointed out that it by no means follows from this that because the time 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, during such a short space of time as from one five thousandth to one ten thousandth of a second. That is quite clear. What the golfer has to do, then, is to make sure that his swing is right at the beginning, that is, in the back-swing and the down-swing, and also in the follow-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 the beginning being right and the end being right, control being exercised over each, the middle is right also, though in this case there is no control over it.

This quotation emphasises strongly the fact which I have always insisted on, that the matter of impact with the golf ball is an incident in the travel of the head of the club, and that it is practically impossible for the player to 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 during impact, but it is a remarkable thing to see James Braid claiming that at the moment of impact there is "no control over" the swing although there is both in the downward swing and the follow-through! I need not criticise this.

The point, however, which I wish to refer to here specifically is in connection with the follow-through. Braid says, finally:

What the golfer has to do, then, is to make sure that his swing is right at the beginning, that is, in the back-swing and the down-swing, and also in the follow-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 the beginning being right and the end being right, control being exercised over each, the middle is right also, though in this case there is no control over it.
