I consider that these experiments prove beyond a shadow of doubt, as I personally never doubted, that the ordinary bramble-marked golf ball will not run truly unless it has a considerable amount of force behind it, and that for short puts, and particularly on anything like a fast green, it is a most treacherous ball. Sir Ralph Payne-Gallwey says:

All this goes to prove that, although a ball may be of inaccurate make, it keeps its line to near the end of its course when hit hard along the ground, as for instance, in a long running up approach to the hole from the edge of a putting green. It is also clear that a ball with an incorrect centre of gravity will very seldom run true off the putter if the ground is hard, fast and smooth and the distance it is required to travel is only a few feet. For this reason manufacturers should consider the accuracy of a ball for short puts—accuracy that can only be gained by making it a perfect sphere with its centre of gravity in the exact centre of the ball; for short puts must lose many more matches than short drives.

As Sir Ralph Payne-Gallwey truly says, with a badly balanced ball the easiest of short puts may fail, especially on a downward slope, though the player rarely suspects that his ball and not his skill is to blame.

It is not, as I have already pointed out, only the question of the badly balanced ball which is of such vital importance in short puts, but it is the question of the untrue running of the ball marked by excrescences; also there is the equally important matter, which I have referred to, of the untrueness of the ball marked by excrescences in coming off the face of the putter. I am firmly convinced that there is no more perfect marking for a golf ball than that used for the old guttie ball, that is a marking by indented lines, but even here I believe that equally good results, both in flight and run, would be obtained if the gutta-percha ball were marked in a similar manner but with fewer lines.

Some of Sir Ralph Payne-Gallwey's conclusions are important. He suggests that a golfer should carefully test a ball before using it in an important match, and this is, unquestionably, from a scientific point of view, a very sound and good suggestion. I have already indicated his method of testing a ball for its centre of gravity, and I have shown how the ball may be tested for its spherical shape. There is no necessity to apply any test whatever to the ball in so far as regards its marking. There is one maxim with regard to that—avoid anything in the shape of a golf ball marked by excrescences.

Sir Ralph Payne-Gallwey's advice to golfers with regard to the balls need not be given here in full, valuable as I believe it to be in the main. But there is one matter which is worth repeating. He says:

Select a ball with as smooth a cover as you can find, for though all golf balls require to be roughened in order to steady their flight, those most deeply scored travel the shortest distance, and are most affected by a head or side wind.

This is very sound and important advice, and it should receive the attention not only of golfers, but of the golf ball manufacturers, for even those balls which are now marked by indentation are, in my opinion, too freely marked, and I am inclined to think that the dimples on the golf balls which are so marked, are, if anything, too large and too frequent. I think it is extremely probable that the balls which are so marked would fly and run better than they do now if they were marked by lines as the old guttie was marked, but with fewer of these lines. Probably if they were marked with one-third of the number of lines which were used on the old guttie, we should have a perfect flying and running ball.

Before closing this chapter on the make of the golf ball, it will be interesting to refer once again to the results obtained by Sir Ralph Payne-Gallwey when throwing the smooth ball from his machine and also when having it driven by Edward Ray. He obtained results similar in all respects to those which George Duncan and I obtained when trying "The Ruff." It is very curious indeed that so far there have not been any definite scientific experiments made to show exactly where the serviceable degree of roughness ends and the prejudicial begins, though much has certainly been done since I started the controversy about the relative merits of a smoother ball.

Some golf ball makers have gone so far as to produce a dimple ball with a small pimple in the dimple. This, in effect, reduced the dimple to a ring, and these balls have been found to fly and run very well, but all that has been so far done has been a matter of experiment, of rule of thumb work. I do not think that there is a firm of golf ball makers in England which is in possession of a proper mechanical driver. We are assured that at least one firm in America is in possession of such a machine, but so far as I am aware there is no efficient machine of such a nature in England. This is very remarkable, as with such a machine a firm of golf ball manufacturers could obtain results which would probably give them a big advantage over their competitors.
