"Not necessarily," she said. "But as a general rule people whose lives have been simple and upright do not need to live under an assumed name. Of course there might be exceptional cases--and there is a difference between an alias and an incognito." "What's an incognito?" questioned Nan. "Why, if a person of rank or importance travels through a country and wishes to escape publicity, he often does so incognito--that is, unknown. He will drop his official title and take his family name or part of his family name with a simple prefix. For instance, a king might care to be known as the Duke of So-and-so; a Duke as Mr. ----, whatever his surname chanced to be. That would not be wicked and it would not be an alias. And sometimes people who are not nobles find it desirable to remain unrecognized for a time. Take it for granted that I was not, in reality, a governess at all; I mean that I was not forced by circumstances to take such a position, but that I for some reason chose to assume it. That I cared to come here and be with you because I had known and loved your parents long ago and wished to do my best for their child. Then suppose I did not care to disclose my identity to--to--people because of--well, no matter--I simply came here giving you but part of my name--not the whole, why it might not be a wise course, but it certainly could not be called a wicked." "Oh, how I wish you had," cried Nan. "It would be splendid fun. Just like a princess in disguise and things. Say you aren't a governess and that your name isn't Blake. Oh, please do. It'll be just like fairy-stories if you will." "How can I, dear, when I am and it is?" replied the governess, slowly. "I am no princess in disguise, I assure you. I am simply a very prosaic little woman and your devoted friend. I don't think I could possibly discover anything at all resembling a fairy-tale in my life. But some time, perhaps, when you are older, and when--I mean, if we meet again, I will tell you all there is to tell about myself--that is, if you care to listen. It will not be exciting--but you might care to know it." "Oh, I would, I would!" the girl exclaimed heartily. "But I hate to have you talk of 'if we meet again.' Why, we must, Miss Blake. Don't you know I couldn't live and know I wasn't to see you any more? It's like the most awful thing that could happen to have you go way at all, and the only way I can bear it is thinking of how we'll see each other often and often. Why, my father will be so thankful to you for taking such care of me! I guess he won't know what to do. And when you see him and find how good he is, you won't be afraid a bit. You'll just as lief stay here as not. He's the best, the dearest--oh, you couldn't help but like my father."
