The important fact to be remembered in selecting a system of signals is that it is far more demoralizing to confuse your own team than to mystify your opponents. A captain must therefore choose such a set of signals as he can be sure of making his own team comprehend without difficulty and without mistake. When he is sure of that, he can think how far it is possible for him to disguise these from his opponents. Among the teams which contest for championship honors it is unusual to find any which are not prepared for emergencies by the possession either of two sets of signals, or of such changes in the manner of giving them as to make it amount to the same thing. Considering the way the game is played at the present time, this preparation is advisable, for one can hardly overestimate the demoralizing effect it would have upon any team to find their opponents in possession of a complete understanding of the signals which were directing the play against them. [Illustration: R. HODGE. Princeton.] While it is well for the captain or coach to arrange in his own mind early in the season such a basis for a code of signals as to render it adaptable to almost indefinite increase in the number of plays, it is by no means necessary to have the team at the outset understand this basis. In fact, it is just as well to start them off very modestly upon two or three signals which they should learn, and of which they should make use until the captain sees fit to advance them a peg. If, for instance, the captain decides to make use of a numerical system, he cannot do better to accustom his men to listening and following instructions than to give them three signals, something like this: One-two-three, to indicate that the ball is to be passed to the right half-back, who will endeavor to run around the left end; four-five-six, that the left half will try to run around the right end; and seven-eight-nine, that the back will kick. The scrub side will probably "get on" to these signals in short order, and will make it pleasant at the ends for the half-backs; but this will be the best kind of practice in team work, and will do no harm. After a day or two of this it will be time to make changes in the combination of numbers, not only with an idea of deceiving the scrub side, but also to quicken the wits of the 'Varsity team. Taking the same signals as a basis, the first, or signal for the right half-back to try on the left end, was one-two-three--the sum of these numbers is six. Take that, then, as the key to this signal, and any numbers the sum of which equals six will be a signal for this play. For instance, three-three, or four-two, two-three-one--any of these would serve to designate this play. Similarly, as the signal for the left half at the right end was four-five-six, or a total of fifteen, any numbers which added make fifteen--as six-six-three, seven-eight, or five-four-six--would be interpreted in this way. Finally, the signal for
