When the ball is kicked, a member of the opposing team who raises his hand and stands in one spot is entitled to make a catch without interference, which if successful gives his team a free kick. In a free kick his opponents may not come within ten yards of where the ball was caught and some member of his team may kick either a drop kick, punt or place kick as he sees fit. After a touchdown, which counts five, a place kick for goal is attempted. If the ball goes between the goal posts and above the crossbar it counts one point additional for the team making the touchdown, or six in all. A score of one alone cannot be made in football, as the attempt for goal cannot be made until after a touchdown. This of course does not apply to a field goal, which may be attempted at any time while the ball is in possession of the team and which counts three. The smallest score is from a “safety,” which results when a member of a team is forced to touch the ball down behind his own goal or is downed there by the opposing team. This play counts two for his opponents and is an evidence of weakness of the team. It has the advantage, however, of permitting the ball to be brought out twenty-five yards to be put into play. The rules of football were practically unchanged for a number of years, but the game developed so many dangerous features that nearly all the colleges recently agreed to certain important changes especially directed to abolishing mass play and line bucking. For that reason the rules for the present game may be changed considerably within a few years. A boy taking up football should therefore acquaint himself with the latest rules governing the sport. Football requires careful training, but the best training will come from actual play itself. In the beginning of the season a period of ten minutes’ hard play is all that a boy should be called upon to do, unless he is in excellent physical shape. After that the time of practice should be lengthened until a candidate can go through a game of two full halves without being exhausted. One reason for many football injuries is that the players become so completely winded that the ordinary power of resistance is lost. Besides actual play the best training is in taking long runs to improve the wind, one of the most essential things in football. In the colleges training for nearly all athletic events is done in this way and a candidate who cannot go out with his squad and run four or five miles at a stiff dog trot will have but little chance of making his team.
