In order that those interested in football may more fully understand the changes in the rules for 1910, it may be well to review the work of the committee and to state and explain what the changes are, although it is difficult to do so briefly, without the use of many technical terms.

One thing particularly should be clearly understood,--that the underlying purpose of the new rules was to minimize the element of danger in the game. To this purpose the committee adhered throughout all its work, and it should be commended for its single-minded efforts in this direction.

A list of the rules passed for the purpose of ensuring greater safety and an analysis of their probable effect shows how many and drastic the changes are. Moreover the other rules, though made in part for other reasons, should also help in the result sought for.

The changes made primarily to diminish the likelihood of physical injury were, briefly, as follows:

1. The halves are subdivided into four periods of 15 minutes each, so that the prolonged strain of 35 minutes of continuous play will now be removed, and the total time of play is reduced 10 minutes.

2. Players once withdrawn from the game can now be resubstituted, so that there is now no longer the temptation to play a man to the limit of his endurance before he is removed.

3. Flying tackles have been prohibited, in the hope that the heavier shocks of tackling may be prevented.

4. The runner is prohibited from "crawling" after being once downed, so that any "piling up" on the runner may be stopped.

5. The team on the offensive is prohibited from pushing or pulling the man running with the ball, a rule which should practically eliminate heavy mass plays.

6. Seven men of the team on the offensive must remain on the line of scrimmage, so that only the backs may now be utilized to deliver a "direct attack" on the defensive line.

7. The receiver of a forward pass or on-side kick is to be more adequately protected, so as to remove the danger of a severe shock to a man unprepared and off his balance.

The other principal changes which should be outlined before discussing the rules as they will appear in the rule book are:

1. The teams no longer change goals after each touchdown or goal, but at the beginning of each of the four periods.

2. The player first receiving the ball from the snapper-back may run with the ball across the line of scrimmage at any point.

3. A forward pass over the line of scrimmage may cross said line at any point, but must be passed from a point at least five yards back thereof, and cannot be legally caught by a player of the offensive side after it has gone more than 20 yards into the opponent's territory.
