Don't refuse to play with one whose handicap is much greater than yours or press a game upon one whose handicap is much less.

Don't, when making a match, try to get greater odds by saying that your handicap is unfair.

Don't play for too large stakes, as it is apt to cause hard feelings and to lose a friend. 1 here is enough in the game itself to make it pay for the time given to it.

Don't move about or stand too close to your opponent when he is driving off, and don't talk with others or practise swinging while he is addressing the ball.

Don't, on the putting green, get in your opponent's line of sight or stand too near him. Keep quiet and do not strike matches.

Don't, if you miss your putt, swear about it, - that is, out loud. It is not only "contra bonos mores" but is bad for the caddy. The man who has grit enough to refrain from swearing has grit enough to pull himself together.

Don't be always finding fault with your own bad luck and your opponent's good luck.

Don't praise your own good shots. Leave this for your opponent to do. On the other hand, don't crab his good shots.

Don't, if you have no caddy, order your opponent's caddy about as if you were paying for his services. Any act of the caddy is a courtesy extended to you by your opponent.

Don't, if you are playing a slow game and a faster couple is behind, fail to ask them to pass. It will be more comfortable for all. Elderly golfers who seem to feel that it is humiliating to have others pass them should realize that elderly foozling is not interesting to watch.

Don't, when you miss an easy putt because you were too jolly lazy to take any pains, say to your opponent, "of course, I will give you the hole if you insist upon it."

Lost ball.
