"I know what you would ask," she went on. "Why, then, you would ask, did I ever leave the Islands?... But this had always been understood between us. I cannot tell you how. For years we never talked about it, yet we always talked as if, some day, it must happen. The fate was on us to be separated; and the strange part of it was," continued Vashti, throwing out her hands involuntarily, and with this action changing as it were from a confident woman back to a child helpless before its destiny, "we understood from the first that I, who loved the Islands, must be the one to go, while Ruth would find a husband here and settle down, nor perhaps ever wish to cross over to the mainland. You see, of the two I was the reader; and sometimes when I read Shakespeare to her--for we possessed but a few books, and some of these, like 'The Pilgrim's Progress,' had no real scenery in them to take hold of--sometimes when I read Shakespeare, or 'The Arabian Nights,' or 'Mungo Park's Travels,' and the real world would open to me, with cities like London, or Venice, or Bagdad, and with woods like the Forest of Arden, and ports with shipping and great empty deserts, then Ruth would catch hold and cling to me, as if I was slipping away and leaving her before the time.... Yet we both knew that the time must come, in the end. Do you understand at all?" she broke off to ask. "Yes," he answered. "I cannot tell how, but as you put it I seem to see it all." She glanced at him with a quick, grateful smile. "Well, that is just how it happened, and if I were to explain and explain I couldn't make it any clearer. You understand, too, there was never any question of my leaving Ruth until she was grown a woman and could see with a woman's eyes. Then I knew she was safe. She had more common-sense even than I. She was born to marry--I never doubted that; but when I saw also that she was a woman to choose for herself and choose wisely--why, then I saw also, and all of a sudden, that the time had come and I was better out of the way; better, because a teacher has to know when to stop and trust the teaching to prove itself. Else by lingering on, he may easily do dreadful mischief, and all with the best will in the world. Do you understand this, too?" Again the Commandant bent his head; for again, without knowing how or why, he understood. "Well, I left the Islands, and there is no need to trouble you with my own story--though some day I will tell it if you care to hear. It contains a great deal of hard work, much good fortune, some suffering, too; and on the whole I am a very grateful woman, as I ought to be.... But we were talking of Ruth. She married, as she was born to marry, and her husband is a good man. She has children, and her letters are full of their sayings and doings, as a happy mother's should be. So, you see, our instinct was wise, and I did well to depart."
