It is remarkable, when one considers the vast number of scientific men who play golf, how little attention has been directed by them to the form and make of the golf ball. Many golfers are under the impression that the golf ball which is now used represents the limit of man's inventive genius. Probably the leading maker of the best feather ball in the days before the guttapercha ball was known would have thought the same. As a matter of ascertained fact the vast majority of golf balls which are made to-day are imperfect in a variety of ways. There can be no doubt whatever that the ball which is marked by what are commonly called pimples, or bramble marking, is a most imperfect production.

If one were to suggest to a billiard player that it would improve the run of the balls if they were covered with little excrescences similar to those which are on many golf balls, he would be pitied or maltreated, yet Mid-Surrey greens are not many removes from a billiard table, and putting is quite half the game of golf, as I think has been remarked by a great number of people, but is nevertheless not sufficiently considered by golfers, especially in the matter of choosing golf balls.

It is not necessary, in considering the question of the golf ball, to bore people, as is usually done, with the history of the evolution of the golf ball, from the time when prehistoric men used a knuckle bone or something like that, right down through the feather ball period up to the present time. It will not be necessary for me to go back any further than the period of the gutta-percha ball. Most golfers will remember that the guttie was not a perfectly smooth ball; it was marked with grooved lines running round it. These crossed each other at various angles, producing, generally speaking, squares, although, naturally, some of the markings, where the lines did not cross at right angles, were irregular, but the principle of the marking was by indentation.

The bramble marking, or marking by excrescence, is an idea which has obtained a hold more recently, and it is certain, from a practical and scientific point of view, that it is a very imperfect marking.

It is a curious thing that in golf, where a very great amount of accuracy is demanded, particularly when one is playing a short put on a fiery green, the ball should be, so far as I am aware, the only ball which is deliberately constructed on principles which if applied to a billiard ball would make the ball what billiard players call "foul," that is, a ball which runs untruly.

It is unquestionable that sufficient thought has not been given to this matter. Very few people understand that it is practically impossible to place a ball with bramble markings on a perfectly true surface so that it will remain in the exact place where it was put, even if it were deposited on this spot by mechanical means. It is not hard to understand that this is natural when we remember that a golf ball which is marked by the excrescences called pimples or brambles comes to rest on a tripod of excrescences, and indeed it sometimes requires to find a base of four of these excrescences before it settles down.

Any thinking golfer will be able to understand very easily that this must make for instability, and he will see clearly what it means when a ball is rolling very slowly. Let us imagine, for instance, that a golfer is playing an approach put of twenty yards. It is evident that while the main force of the blow is behind the ball it will enable it to overcome much of the untrueness of the ball, but it is equally apparent that as the force is dying away at the critical time when one wishes the ball to run truly on its course to the hole, it is most prone to waver. It is at times like this that the golfer blames the "beastly green," whereas if he knew as much as he should about the make of a golf ball he would know that he had only himself to thank for playing with such an extremely imperfect thing as the golf ball which is marked by excrescences.

It is of course clear that on a putting-green the ball with excrescences sinks into the turf, and whilst it is running with any considerable force behind it, it makes for itself what may be termed a trough to run in, which is equivalent in depth practically to the hole which the ball would make when lying at rest on the green. This is the only thing which saves the ball marked with excrescences from being a much worse failure than it is. It is, however, when one comes to put with it over a hard, keen, or bare green that its wonderful imperfection is shown.

Many golfers, on account of the fact that an ordinary putting-green does assist this imperfect ball to this extent, are inclined to maintain that the ball is sufficient for the needs of golf. They forget, of course, that a ball with these excrescences must necessarily be more inaccurate off the face of the putter than would be a ball marked by indentation, for when a ball is marked by indentation, either of the dimple pattern, which has come into vogue more recently, or of the lines which were used in the old days, it undoubtedly will run more truly than if marked by excrescences, for the reason that the indentation is bridged in such a manner that it is not felt to the same extent as is an excrescence.

I may illustrate this by applying the marking of an old guttie to a billiard ball. Let us consider for a moment that the billiard ball has been marked by having lines sawn in it similar to those on a gutta-percha ball; these lines would not affect the trueness of the running of a billiard ball to a very great extent. But let us, on the other hand, imagine that instead of lines being sunk in the ball, these lines had been put in a network on the ball, so that they were raised from the surface of the billiard ball. It is obvious that such a ball would be absolutely impossible, and it would be an extremely foul-running ball.

There is another point to be considered in connection with this matter of marking by indentation or by excrescences. It would be almost a matter of impossibility to stand a ball marked by excrescences so that it balanced on the point of one of the pimples. On the other hand it would be perfectly natural for a ball marked by a dimple of corresponding diameter to the base of the pimple, to come to rest on the "ring" formed by that dimple. We have already seen that the ball marked by excrescences requires three or four of those excrescences to rest on before it becomes stationary. Roughly, therefore, the instability of the ball marked by excrescences is at least three times as great as that of the ball marked by indentation, and if we contrast the ball marked by excrescences with the ball marked by the old gutta-percha marking, the difference would probably be very much greater against the bramble marking.
