in that part of the line towards which his pass is to be delivered; and here, again, he should hold the ball for another down rather than take any chance of the opponent's intercepting the pass. After letting the ball go, the quarter should follow his pass; in fact, he should be almost on the run as the ball leaves his hand. No matter whether the ball be caught or fumbled, he is then ready to lend assistance; whereas if he stand still after his pass, he is of no use to the rest of the play. When the play is a run, he can do excellent work in interfering; and when the play is a kick, he can take any opponent who gets through, and thus aid the half in protecting the kicker. In either case, if his own man muff or fumble he is close at hand to lend assistance in an emergency, which otherwise might prove most disastrous. When lining up the quarter should take a quick glance, not directly at the player he is to make the recipient of the ball, but covering the general position of all the men. In doing this he locates his individual without making it apparent to the opponents which man is to receive the ball. Any amount of disguise may be practised in the way of taking a last glance at the wrong man, or calling out to some one who does not enter into the play. The chief point, nevertheless, is to avoid that tell-tale glance at the right man which is so difficult to omit. [Illustration: RALPH WARREN. Princeton.] When the opponents have the ball, the quarter makes an extra man in or near the forward line, and, as a rule, he can by his shrewdness make it very uncomfortable for any point in the line which he chooses to assail. No law can govern his tactics in this respect, but he should be a law unto himself, and show by his cleverness that he is more valuable than any man in the line whose position is fixed. One caution only is worth giving to the quarter in this line of play, and that is, to be less free of going forward sharply when the play is evidently to be a run than when a kick is to be attempted. In the latter case, a quarter can always be sent for his best. THE HALF-BACK AND BACK
