Long after the rest were asleep, Rose lay wide awake, excited by the novelty of all about her, and a thought that had come into her mind. Far away she heard a city clock strike twelve; a large star like a mild eye peeped in at the opening of the tent, and the soft plash of the waves seemed calling her to come out. Aunt Jessie lay fast asleep, with Jamie rolled up like a kitten at her feet, and neither stirred as Rose in her wrapper crept out to see how the world looked at midnight. She found it very lovely, and sat down on a cracker keg to enjoy it with a heart full of the innocent sentiment of her years. Fortunately, Dr. Alec saw her before she had time to catch cold, for coming out to tie back the door-flap of his tent for more air, he beheld the small figure perched in the moonlight. Having no fear of ghosts, he quietly approached, and, seeing that she was wide awake, said, with a hand on her shining hair,-- "What is my girl doing here?" "Having a good time," answered Rose, not at all startled. "I wonder what she was thinking about with such a sober look?" "The story you told of the brave sailor who gave up his place on the raft to the woman, and the last drop of water to the poor baby. People who make sacrifices are very much loved and admired, aren't they?" she asked, earnestly. "If the sacrifice is a true one. But many of the bravest never are known, and get no praise. That does not lessen their beauty, though perhaps it makes them harder, for we all like sympathy," and Dr. Alec sighed a patient sort of sigh. "I suppose you have made a great many? Would you mind telling me one of them?" asked Rose, arrested by the sigh. "My last was to give up smoking," was the very unromantic answer to her pensive question. "Why did you?" "Bad example for the boys." "That was very good of you, uncle! Was it hard?" "I'm ashamed to say it was. But as a wise old fellow once said, 'It is necessary to do right; it is not necessary to be happy.'" Rose pondered over the saying as if it pleased her, and then said, with a clear, bright look,-- "A real sacrifice is giving up something you want or enjoy very much, isn't it?" "Yes." "Doing it one's own self because one loves another person very much and wants her to be happy?" "Yes." "And doing it pleasantly, and being glad about it, and not minding the praise if it doesn't come?" "Yes, dear, that is the true spirit of self-sacrifice; you seem to understand it, and I dare say you will have many chances in your life to try the real thing. I hope they won't be very hard ones." "I think they will," began Rose, and there stopped short. "Well, make one now, and go to sleep, or my girl will be ill to-morrow, and then the aunts will say camping out was bad for her." "I'll go,--good night!" and throwing him a kiss, the little ghost vanished, leaving Uncle Alec to pace the shore and think about some of the unsuspected sacrifices that had made him what he was.
