But we may borrow from the slope in another way than by running straight up it and straight down again. If we put cut on the ball, it will of itself be fighting against the hill the whole way, and though if the angle is at all pronounced it may not be able to contend against it without any extra borrow, much less will be required than in the case of the simple putt up the hill and down again.
In the first place, I may remark that we do not generally borrow from a slope "by running straight up it and straight down again." The path of the ball is generally, almost from the time it is hit, a curve, and a gradual curve, in which one sees to it that the ball is at its farthest from the straight line to the hole somewhere about midway to the hole. But this idea of putting cut on the ball with a putter, which is sufficient to hold the ball up against the hill for any appreciable distance, is practically a delusion. I can easily understand that if Vardon plays the cut put as he himself directs it to be played, that he thinks that cut administered to a ball by an ordinary putter may have a very great effect in holding the ball up against the side of a hill for a considerable distance, but this really is not so. Putting, however, as Vardon instructs one to put for obtaining cut, would in itself punch the ball up against the slope of the hill, and I can easily believe that anybody who plays the put like this, thinking that he is obtaining cut by so doing, will be under the impression that cut is a very useful thing for holding the ball up against the slope in this manner, whereas he is in effect simply punching the ball up against the slope—in other words, he is playing a put, which if the green were perfectly level, would be yards off his line to the hole and to the right of it.
Vardon goes on to say:
Now it must be borne in mind that it is a purely artificial force, as it were, that keeps the ball from running down the slope, and as soon as the run on the ball is being exhausted and the spin at the same time, the tendency will be, not for the ball to run gradually down the slope—as it did in the case of the simple putt without cut—but to surrender to it completely and run almost straight down.
There is a fundamental error here, for Vardon states that practically the spin on the put and the run on the ball will be exhausted at the same time, but it is an utter impossibility to calculate with any exactness whatever as to what happens in such a case. Vardon knows no more about it than any other golfer, and all that any golfer knows about this is extremely little, so that to advise anyone to attempt to hold his ball up against a slope by the application of cut with any ordinary putter, particularly a broad-soled putter, is to invite him to play his shot blindfolded.
Vardon does not mention the length of the put which he considers it possible to play with this cut, but in his diagram he shows a put which would conceivably be quite a long put, let us say for the sake of argument fifteen or sixteen feet, but the theory would be just as bad if it were much less. He says:
Our plan of campaign is now indicated. Instead of going a long way up the hill out of our straight line and having a very vague idea of what is going to be the end of it all, we will neutralise the end of the slope as far as possible by using the cut and aim to a point much lower down the hill—how much lower can only be determined with knowledge of the particular circumstances, and after the golfer has thoroughly practised the stroke and knows what he can do with it. And instead of settling on a point half-way along the line of the putt as the highest that the ball shall reach, this summit of the ascent will now be very much nearer the hole, quite close to it in fact. We putt up to this point with all the spin we can get on the ball, and when it reaches it, the forward motion and the rotation die away at the same time, and the ball drops away down the hill, and, as we hope, into the hole that is waiting for it close by.
Vardon may well say "as we hope," for the put described by him has no more chance of being brought off on a putting-green than Vardon has of winning another open championship from an aeroplane. To speak of putting a ball in this manner, and treating it with such magic that when it gets up by the hole the forward motion and the rotation die away at the same time, is not practical golf, but absolute moonshine, for it would be an utter impossibility to persuade any golf ball which has ever been made to receive from any known form of golf club sufficient cut to make it behave in the manner described. The theory of the thing on paper is to a very great extent right, with the exception that the cut described would require to be obtained by a club with a much greater loft than any ordinary putter; but it is evident that putting with putters such as those which Braid or Vardon use, it would be an utter impossibility to get cut on the ball which would stay with the ball during a long put and exert much influence in holding the ball up against any appreciable slope, for with these putters, which have not much loft, it is evident that any spin whatever which is imparted to them by drawing the putter across the line of run at the moment of impact will be mainly about a vertical axis which is, in effect, the spin of a top. It is evident that as the ball progresses across the green there will be a very strong effort indeed on the part of the ball, following its friction on the green, to wear down this vertical motion and convert it into the ordinary roll of a naturally hit put.
Even when one is putting with a highly lofted club and with a tremendous amount of drag on a perfectly flat green, the drag goes off the ball in a wonderfully short space of time, and here, of course, one is using a spin which is analogous to the drag of the billiard player, for it is pure back-spin which is fighting in the same plane the forward roll of the golf ball. Therefore it is reasonable to suppose, and indeed it is undoubted that the ball would be more likely to retain this pure back-spin for a much longer time than would the ball with the side-spin imparted by the putter, for the spin which is imparted by the putter does not directly fight the forward progress of the ball as it is spinning across the plane of the roll which the ball desires to take, whereas, as I have before pointed out, the ball played with drag is absolutely fighting the forward roll of the golf ball. It therefore would for a very short distance skid over the putting-green, but those who only theorise about these matters have a ridiculously exaggerated idea of the influence of drag on the golf ball.
I have made it very plain, and I cannot emphasise the matter too strongly, that any attempt whatever in long puts to use drag or cut of any kind is to be deprecated.
