"'Just listen. Of these four years, two only will be spent at the house; the other two you are to travel with your pupil. You want to see the world, and you ought to see it, even if it were only in order to learn that men have a right to like dogs everywhere. You have no means of your own, and you are too civilized to be a good vagabond. Well now, here you have the finest opportunity, such as may not present itself a second time in all your life.' "'And who is the Alexander whose Aristotle I am to be?' "'A young lord, like the hero of Macedonia. I have seen the noble race last year in Ostend. The father, a Baron Grenwitz, is a nullity; the baroness, an unknown quantity, which I could not ascertain. At all events, she is a clever woman. I know that that is no small attraction for you. She speaks three or four modern languages, to say nothing of her mother tongue.

"'Then I am the last of the Mohicans, and smoke my calumet in loneliness on the grave of my Uncas.' "He rested his head on his hand, and stared grimly at the distance. 'Yes, yes, I know,' he growled, 'the Big Serpent, when it is tired hissing at men, will creep into a deep morass and perish there alone.' "I took his hand in mine: 'That shall not be so; at least not as long as I live.' "He looked at me sadly. "'But you will die before me,' he said; 'the big Serpent is tough and you are soft--much too soft for this hard world. But let us leave that alone. What do you think of my offer?' "'That I like it only so-so.'
