"And that is why you chose me instead of Grace to take charge of your keys," interrupted Edith, beginning to comprehend what had heretofore been strange to her. "But, Mr. St. Claire, I don't understand it at all--don't see why there was any need for so much secrecy. Supposing you did dread neighborhood gossip, you could not help being chosen Nina's guardian. She could not help being crazy. Why not have told at once that there was such a person under your charge? Wouldn't it have been better? It was no disgrace to you that you have kept the father's trust, and cared for his poor child," and she glanced lovingly at the pretty face nestled against her arm, for Nina had fallen asleep. Arthur did not answer immediately, and when he did, his voice trembled with emotion. "It would have been better," he said; "but when she first became insane, I shrank from having it generally known, and the longer I hugged the secret the harder I found it to divulge the whole. It would look queerly, I thought, for a young man like me to be tramelled with a crazy girl. Nobody would believe she was my ward, and nothing more, and I became a sort of monomaniac upon the subject. Had I never loved her--" he paused, and leaned his head upon his hands, while Edith, bending upon him a most searching look, startled him with the words, "Mr. St. Claire, you have not told me all. There is something behind, something mightier than pride or a dread of gossip." "Yes, Edith, there is something behind, but I can't tell YOU what it is, you of all others." He was pacing the floor hurriedly now, but stopped suddenly, and standing before Edith, said: "Edith Hastings, you are somewhat to blame in this matter. Before I knew you I only shrank from having people talk of my matters sooner than was absolutely necessary. But after you became my pupil, the desire that you should never see Nina as she is, grew into a species of madness, and I have bent every energy to keeping you apart. I did not listen to reason, which told me you must know of it sooner or later, but plunged deeper and deeper into a labyrinth of attempted concealment. When I found it necessary to dismiss Mrs. Johnson, if I would keep my affairs to myself, I thought of the old family servants at Sunnybank. I knew they loved and pitied Nina, and were very sensitive with regard to her misfortune. It touches Phillis' pride to think her young mistress is crazy, and as hers is the ruling mind, she keeps the others in subjection, though old Judy came near disclosing the whole to you at one time, I believe. You know her sad story now, but you do not know how like an iron weight it hangs upon me, crushing me to the earth, wearing my life away, and making me old before my time. See here," and lifting his brown locks, he showed her many a line of silver. "If I loved Nina Bernard, my burden would be easier to bear."
