I have discovered that the rules of the great game of life are not so simple as I at first supposed. I see at last what you mean by your doctrine of self-sacrifice. In base-ball we often have to make what we call a sacrifice hit, which brings in another runner while the batter himself gets put out. Then, too, the question sometimes comes up whether to try for a very hard ball, and take ten chances to one of making an error and spoiling your individual record; or only pretend to try and miss it, and so save your individual record at the expense perhaps of losing the game. Essentially the same principle comes out in all our games. In hare and hounds the hares run over the most difficult and devious course they can find, dropping pieces of paper behind them at intervals for scent. Then the hounds come after them on this trail. All goes well as long as the trail is clear and the scent is good. Then we come to a point where all scent stops. Then the lazy shirks sit down and wait, while the energetic fellows strike out in all directions, until one of them finds the trail. He shouts to the others, and they all follow him. Now, this willingness to strike out and help find the trail for the rest, instead of sitting down and resting and letting someone else do it, is, I suppose, what you mean by self-sacrifice.
