--'Because ours is much more complicated than yours. The only danger we have to watch against when we play your game is to be caught in an unguarded moment by a movement which is foreign to us. I mean, for instance, your knights move sidewards or backwards, and we are often caught by it, because our knights move only forwards.' --'But what do you mean by saying, your chess being more complicated?' asked another. --'I will only outline the reason, for it is impossible to demonstrate it in the short space of a _Summer Dream_.' --'What!' --'Well, I mean to say that it would take a long time were I to describe it in detail, but listen: In the first place, the squares of our boards are nine by nine, therefore there are seventeen more squares than yours: the number of our men are twenty in all on each side, two rows of nine each, and two extra, and, therefore, four more men than yours on each side. Then, again, in your game, when you take one of your opponent's pieces, you put it aside and never make any use of it except under one particular circumstance, which I need not describe. With ours, however, either side of the players can make use of any of the captured pieces of his opponent and add them to his own men, at any time and place, and under any circumstance, provided that he brings them on to the board, one at a time, in his turn of move.' --'But how can you make any distinction between your own men and those of your opponent, if you put down the opponent's men as your own?' said another. 'Well, we have no difference of colour between friends and foes and our men are made flat _ab initio_, and are laid on the squares with their heads turned towards the enemy, so that one can easily distinguish friends from foes by the position in which they are placed.' --'How can you turn the head towards the enemy?' asked one. --'By the head, I do not mean the head and tail you use when tossing. Our men are made in such a way that one of the four sides has a projected part; and that side is the head. In other words, the head does not mean the flat surface, but rather one of the sides of a flat object. Call it the top, if you prefer.' --'I see,' said one.
