She put her cold hand in his. As he took it, by a curious freak of his brain, there flashed into his mind the memory of the day when, by the side of this fragile white little hand lying in his, Hetty, laughingly, had placed her own, broad and firm and brown. The thought of that hand of Hetty's, and her laugh at that moment, were too much for him, and he dropped Rachel's hand abruptly, and moved toward the door. She gave a low cry: he turned back; she took a step towards him. "I shall never see you again," she said, taking his hand in hers. "I owe my life to you," and she carried his hand to her lips, and kissed it again and again. "God bless you, child! Good-by! good-by!" he said. Rachel did not speak, and he left her standing there, gazing after him with a look on her face which haunted him as long as he lived. Why Doctor Eben should have resolved to sail for England in a Canadian steamer, and why, having reached Canada, he should have resolved to postpone his voyage, and make a trial of the famous springs of St. Mary's, are mysteries hid in that book of Fate whose leaves no mortal may turn. We prate in our shallow wisdom about causes, but the most that we can trace is a short line of incidental occasions. A pamphlet which Doctor Eben found in the office of a hotel was apparently the reason of his going to St. Mary's; all the reason so far as he knew, or as any man might know. But that man is to be pitied who lives his life out under the impression that it is within his own guidance. Only one remove from the life of the leaf which the winds toss where they list would be such a life as that. It was with no very keen interest that Doctor Eben arrived in St. Mary's. He had some faint hope that the waters might do him good: but he found the sandy stretches and long lines of straight firs in Canada very monotonous; and he was already beginning to be oppressed by the sense of homelessness. His quiet and domestic life had unfitted him for being a wanderer, and he was already looking forward to the greater excitements of European travel; hoping that they would prove more diverting and entertaining than he had thus far found travel in America.
