"Oh, Miss Marley, it all came back to me, after twenty years," he exclaimed. "Something about you has haunted my memory ever since I first saw you last week, and the song yesterday made it more definite and more perplexing. I woke in the night and it all came back. I heard that very same song on the train going South as a young man--comparatively young, though you wouldn't call it so. Do you want to sit down a moment and let me tell you? "I haven't even thought of it for a dozen years," he said when they had found a convenient bench. "As I said, we were bound southward, and it was toward night. The seat in front of me was occupied by an exceedingly pretty young lady and a gentleman who must have been her brother or her husband--girls married younger in those days--for their name, which escapes me, was the same. Farther ahead, on the opposite side of the car, was a woman with an infant in her arms and a boy baby of under two years at her side. As it grew late, the older baby grew tired and cross. He wanted his mother, was jealous of the tiny one, and finally he just howled. The young lady before me said a word to her companion and went directly over. "That kid, Miss Marley, was dirty and sticky beyond words, and she was the daintiest, freshest, sweetest girl imaginable. But she smiled and held out her arms and he just tumbled into them. She hugged the little beggar close, never minding her pretty gown, and brought him back to her seat. She seemed to know just what to do--took off his shoes, loosened the neck of his dress and all that, then cuddled him down and sang to him until he went to sleep and after. Her voice was as sweet as yours, and she sang the very same thing, 'And Do You Ken Elsie Marley'--I think she sang it twice or thrice." Perhaps it was Elsie's fondness for children; perhaps it was because he told the story so well; in any event, the girl was touched. And as usual, to cover her feeling, she tried to smile, her dimples rather at variance with the tears in her eyes. He gazed at her curiously. "Wait, Miss Marley, that isn't all," he exclaimed. "As I recalled the young lady, I saw her face only dimly. Now do you know it suddenly comes to me that she had the largest, deepest dimples I had ever seen, one in either cheek. And I remember vowing then and there, in my youthful enthusiasm, that if ever I attempted to paint Madonna she should have just such dimples; they struck me as somehow significant, perhaps symbolic." Elsie's heart was beating wildly. "I wonder--could that have been your mother, Miss Marley?" The girl could not speak for the tumult within her. "It seems as if their name began with M, though it couldn't have been Marley, else I should have noticed on account of the song," he went on kindly, realizing her emotion. "May I ask what was your mother's maiden name, Miss Marley?" Quite upset, Elsie started to tell the truth; said Mi--and stopped short. "Middleton!" he exclaimed triumphantly.
