Life is a very different sort of game. It is a game of chess, and not of solitaire, nor even of checkers. The men are not all pawns, but you have your knights, bishops, rooks,—yes, your king and queen,—to be provided for. Not with these names, of course, but all looking for their proper places, and having their own laws and modes of action. You can play solitaire with the members of your own family for pegs, if you like, and if none of them rebel. You can play checkers with a little community of meek, like-minded people. But when it comes to the handling of a great state, you will find that nature has emptied a box of chessmen before you, and you must play with them so as to give each its proper move, or sweep them off the board, and come back to the homely game such as I used to see played with beans and kernels of corn on squares marked upon the back of the kitchen bellows.
