In the old days men were taught to tackle by what is known as "live tackling." I recall especially that earnest coach, Johnny Poe, whose main object in football coaching was to see that the men tackled hard and sure. Poe, without any padding on at all, would let the men dive into him running at full speed, and the men would throw him in a way that seemed as though it would maim him for life. Some of the men weighed a hundred pounds more than he did, but he would get up and, with a smile, say: "Come on men, hit me harder; knock me out next time." After the first two weeks of the season, Johnny Poe was a complete mass of black and blue marks; and yet how wonderful and how self sacrificing he was in his eagerness to make the Princeton players good tacklers. But there are few men like Johnny Poe, who are willing to sacrifice their own bodies for the instruction of others; and the next best method, and one which does not injure the players so much, is tackling the "dummy." As we look at this picture of Howard Henry of Princeton tackling the "dummy," we all remember when we were back in the game trying our very best to put our shoulder into our opponent's knees and "hit him hard, throw him, and hold him." Henry always got his man. But the thrill of the game is not in tackling the dummy. The joy comes in a game, when a man is coming through the line, or making a long run, and you throw yourself at his knees, and get your tackle; then up and ready for another. I recall an experience I had at Princeton one year. When I went to the Club House to get my uniform, which I wanted to wear in coaching, I asked Keene Fitzpatrick, the Trainer, where my suit was. He said: [Illustration: HIT YOUR MAN LOW] "It's hanging outside." I went outside of the dressing room but could see no suit anywhere. He came out wearing a broad smile. "No," he said, "it isn't out here, it's out there hanging in the air. We made a dummy out of it." And there before me I saw my old uniform stuffed with sawdust. I looked at myself--in suspense. After the men have been given the other preliminary work they are taken to the charging board. The one shown here is used at Yale. It teaches the men quick starting and the use of their hands. It trains them to keep their eyes on the ball and impresses them with the fact that if they start before the ball is put in play, a penalty will follow. A fast charging line has its great value, and every coach is keen to have the forwards move fast to clear the way. Then after the individual coaching is over, the team runs through signals, and the practice is on. Before very long the head coach announces that practice is over, and the trainer yells: "Everybody in on the jump," and you soon find yourself back in the dressing room.
