Even into this the Americans did not plunge suddenly, but rather little by little they stepped in, until it was necessary to do one of two things--either legalize what was being tacitly consented to, or penalize it heavily. The result was that it was legalized. With this concession, though, there went a certain condition which gained a measure of confidence for the new ruling. [Illustration: E. L. RICHARDS. Yale.] To understand just how this state of affairs above mentioned came about one should know that, in the attempt to block opponents when the quarter-back was receiving and passing the ball, the forwards fell into the habit of extending their arms horizontally from the shoulder, as by this method each man could cover more space. For a number of years this went on without detriment to the sport in any way, but after a time there was more or less complaint of holding in the line, and it was ruled that a man must not change his position after the ball was snapped, nor bend his arms about an opponent at such a time. Unfortunately the referee (for at this stage of the game there was no umpire) could not watch the ball and the players with sufficient care to enforce this ruling, and the temper of the players suffered accordingly. It is always the case when a rule is not enforced unflinchingly, no matter from what cause, that both sides suffer, and the tendency always is towards devising additional infringements. The additional infringement in this instance was even worse than could have been foreseen; for, not content with simply blocking or even holding an opponent until the quarter should have passed the ball in safety, the players in the forward line saw an opportunity for going a step farther, and actually began the practice of seizing an opponent long after the ball had been played, and dragging him out of the way of the running half-back. In the thick of the rush line this was frequently possible without risk of discovery by the referee; and, emboldened by successes of this kind, men would reach out even in the open, and drag back a struggling tackler just as he was about to lay his hands upon the runner. It was this state of affairs which brought up the question, "How much should a comrade be allowed to aid the runner?" American football legislators answered this question satisfactorily, after long discussion, by determining that the runner might be assisted to any extent, provided the assistant did not use his hands or arms in performing this office. The first result of this was to lower the arms of the rushers when lined up, and, in spite of some forebodings, this proved really a benefit to the game. The second result has been to perfect a system of flanking a runner by companions who form almost an impassable barrier at times to the would-be tacklers.
