The boy was amazed and bewildered. No idea that the one whom he had always called "father" was not such in reality had ever entered his head; but now that the truth was told him, it seemed strange that he had not always known it instinctively. He had known that Mrs. Matherson was not his own mother, for he was five years old when she assumed that position, and of course he had always known that the two children were not his own sisters, though he loved them as dearly as though they were. But now to find out that he did not really belong to anybody was hard.
