Fullbacks.
The fullbacks are primarily defensive players although they have opportunities for long shots to the forwards. The fullbacks and the halfbacks should never mix up, by guarding the same girl. The fullbacks stay near their own goal. If the right half is guarding the left wing and the center half the center forward, then the left inside remains for the right fullback to guard. When one fullback is up the field, that is, near the fifty-yard line (she must never go beyond the fifty-yard line), the other fullback should be back toward the goal. The players on the defense should never be bunched in front of the goal, and in hitting the ball away from the goal, they should hit out toward the side lines—never across the center. In a corner or a bully the fullbacks should guard the goal closely.
