Tears of joy don't last very long. Nelly's were soon gone, and there was no trace of them when they all went to the other side of the bushes, where they found An Ching, who stood as if spellbound when she saw them. 'However did you find us?' she asked Chang. 'But you must go away,' she added; 'Hung Li may be back any moment. He will kill me if he finds you here,' and she hurried the children into the cart and got in herself. When they were safely in, Chang said: 'This is my son Chi Fu. He will keep a good look-out and I will talk to you here. If Hung Li comes we can walk quietly away. But he can't be back for a long time yet if he has gone to get a mule; the next village is nearly as far as the one you left this morning.' Chang then told them how he and Chi Fu came to be there. 'When I saw you start,' he said, 'I at once went into my house and consulted with my son, who said that he and I must certainly follow you. He got two mules at once and we set off early next morning. We rode hard and reached the river well before noon. At the inn near the river we heard about a party which had crossed earlier, and although the inn-keeper said the children were boy and girl, we felt sure that it must have been you.' Here Chi Fu came up and put in his word. 'Don't forget to tell the young foreign lady that her letter has been sent off,' he said. 'No,' replied Chang; 'I'll tell her. You must go farther away and keep a good look-out on the road the way Hung Li went.' And Chang turned to Nelly and told her that a courier had started for the Peking mission two days ago and taken her letter enclosed in one for the missionary from Chi Fu. 'And did you get my letter?' asked Little Yi. 'We threw it over the wall.' Chang replied that his wife had picked up a piece of paper with some writing upon it, but it was nearly all blotted out by the rain and could not be read. 'It was of no consequence,' said An Ching, at which Little Yi was not pleased. 'How did you manage to find us?' 'We rode on quickly, and very soon saw your cart in the distance; then we followed by a side road too narrow for a cart. When you stopped to rest at noon I got off my mule and came quite close. I saw the young Ku Nai-nai as she lay asleep.' An Ching did not much like this, but she said nothing. Chang continued: 'It was easy to follow you and put up at the same inn at night, especially as Hung Li did not know us. We rode after you this morning, and when we saw that the mule had fallen we left ours with an old man in a hut over there,' pointing beyond the bushes, 'and began to walk towards you. Little Yi saw us coming, and here we are.' CHAPTER XIII THE ROAD TO PEKING 'Now what are you going to do?' asked An Ching. 'We shall follow you to Peking or wherever Hung Li takes you, and then go at once and tell the English gentleman where you are. You have no need to fear now,' turning to Nelly, 'that you will not get home.' 'And can't An Ching come with us?'
