Many players acquire faith enough to play for the back of the hole by using a cleek or an iron for short putts, and they then maintain that these clubs have the quality of keeping the ball true to its line. The putter will do the same thing if used with equal confidence, and that without the risks of either lofting or of those due to using an awkward, ill-balanced club, which an iron or cleek with its face turned in undoubtedly is.
If there are few who play for the back of the hole in ordinary circumstances, there are fewer still who do so when the only line is curved. If there is a moundlet which will cause the ball to diverge to the left, few go to the right just enough to make up for this. They set themselves to dribble the putt very far to the right, giving the unevenness of the ground as much say in the matter as they can. Anybody will play boldly along the top of a ridge when the hole is at the end of it, but most men prefer, to the detriment of their putting when it is on the side of one, to climb high up and drop down, to running quickly along the lower slopes.
In putting there is much to think about, and much more not to be thought of. With long putts, the great stumbling-block is the strength. Before taking his stance the player knows his distance from the hole and the nature of the ground. One glance more after he has done so is sufficient to assure him that he is aiming in the right direction. Looking back and forward between the ball and the hole will tell no more about the distance, but will only distract him from applying the force proportionate to it. For short putts which ought to be holed, the same holds good, except that starting the ball in the exact line is, or ought to be, now more a difficulty than the strength. Some fix upon a spot to play over before addressing the ball, others after; the most diffident get their caddy to point it out when they are about to play. But, however it is come at, there should be no hesitation. There is the line now for strength and accuracy. To take another look at the hole, to think ' Perhaps I am not aiming quite straight,' will certainly prove fatal. You will give an involuntary pull or push, or dribble hesitatingly up to the lip. But with faith in your line, your stroke delivered, you will look up and likely see the ball disappear down the middle - like a rabbit, perhaps, on account of the determined energy of your faith - perhaps by the side (a hole is very large if played at boldly), on account of some bias in the around not noticed, and best unnoticed, but down all the same.
When a putter is waiting his turn to hole-out a putt of one or two feet in length, on which the match hangs at the last hole, it is of vital importance that he think of nothing. At this supreme moment he ought studiously to fill his mind with vacancy. He must not even allow himself the consolations of religion. He must not prepare himself to accept the gloomy face of his partner and the derisive delight of his adversaries with Christian resignation should he miss. He must not think that it is a putt he would not dream of missing at the beginning of the match, or, worse still, that he missed one like it in the middle. He ought to wait calm and stupid till it is his turn to play, wave back the inevitable boy who is sure to be standing behind his arm, and putt as I have told him how - neither with undue haste nor with exaggerated care. When the ball is down, and the putter handed to the caddy, it is not well to say, 'I couldn't have missed it.' Silence is best. The pallid cheek and trembling lip belie such braggadocio.
