Don’t use a large finger hole. Big holes make a ball lop-sided.
Don’t roll a ball down the alley when there is a ball in the pit.
Don’t use a wide grip if you have a small hand, or two narrow for a big hand.
Don’t use chalk on your shoes. It not only cracks the leather, but leaves the runway in bad condition for whoever follows you.
Don’t think your wrist is gone if it hurts after bowling a few games. Change your grip and throw the strain somewhere else.
Don’t bend your back when delivering the ball. With your feet far apart and knees bent you can start the ball with little or no sound.
Don’t be superstitious—13 is a better start than 12.
Don’t think it necessary to be a Sandow. Many lightweights bowl well.
Don’t get discouraged, you can learn. Any able-bodied person, with ordinary nerve and a good eye, can become quite expert with little practice.
Don’t let an alley owner use pins that are worn out.
