Everything went on well in both compounds. Chang came at the call of the little red signal every day, and let An Ching know what he and Chi Fu were doing. Nelly asked Chang if he thought that Chi Fu could tell her the date, and Chi Fu sent her an almanac which had been given to him by a missionary at the beginning of the year, but it was of no use to Nelly until Chang told her that the longest day was only nine days off; so she put a cross at the date which was nine days before the 21st of June, and thus found out the exact date. In this way she knew when Sunday came, and although there would be only one more for her to spend in Yung Ching, she resolved to keep it in the best way she could, by saying over to herself all the hymns she could remember and taking more time for her prayers that morning; neither would she do any teaching or sewing. The day before the one fixed for the moonlight adventure arrived. An Ching had got permission to go and see her relatives the next day; the old servant, who was better, was to go with her. It was very hot, almost too hot to talk. Ku Nai-nai said there would be a thunderstorm. An Ching, Nelly, and Little Yi were sitting on the bench in the small court. They had just had a visit from Chang, who told them not to expect him the next day, as he must go and fetch the mule in the evening. He and Chi Fu would certainly be there the next night, he said, and he cautioned the children to close the window after they had climbed through. Little Yi was almost asleep, and was swaying to and fro as she sat on the bench. Nelly had hold of An Ching's hand, and was telling her how she should send her messages through Chang's mission. Nelly had got over the excitement, and was quietly happy at the thought of going home. How she longed to see her dear father and mother and Baby Buckle! She thought of all this for some time, with her hand still in An Ching's; and An Ching was thinking of her loneliness when the children would be no longer with her, and of Hung Li's wrath when he returned. Then Nelly too was overcome by the heat, and she nodded and bobbed about until at last her head fell in An Ching's lap. An Ching stroked the pretty little cheek, and felt as if her heart would break at losing her friend. She was resolutely keeping back her tears, when all three gave a great start, and the children were wide awake in a moment. There was a loud rumbling sound. 'The thunder!' exclaimed Nelly. But An Ching knew better. She realised that the noise came from a cart passing under the archway into the outer court next to the street, and that Hung Li had come back. She said nothing, and all three stood listening. Sure enough, it was a cart, and the large gate was being opened. The children heard it too, and although no one spoke a word, each one knew that it must be Hung Li. There was no mistaking now; it was his voice in the inner court talking to Ku Nai-nai.
