'We are obliged to,' said Miss Stafva. 'Those bats are Mistress Sorrow's birds, and she has commanded us to receive them.' Ingrid saw that Miss Stafva did not wish to say anything more about that matter, and she began to sew again; but she could not help speculating over who that Mistress Sorrow could be who had so much power here that she could compel Miss Stafva to give up a whole room to the bats. Just as she was thinking about all this, she saw a black sledge, drawn by black horses, pull up outside the veranda. She saw Miss Stafva come out and make a low curtsy. An old lady in a long black velvet cloak, with many small capes on the shoulders, alighted from the sledge. She was bent, and had difficulty in walking. She could hardly lift her feet sufficiently to walk up the steps. 'Ingrid,' said her ladyship, looking up from her knitting, 'I think I heard Mistress Sorrow arrive. It must have been her jingle I heard. Have you noticed that she never has sledge-bells on her horses, but only quite a small jingle? But one can hear it--one can hear it! Go down into the hall, Ingrid, and bid Mistress Sorrow welcome.' When Ingrid came down into the front hall, Mistress Sorrow stood talking with Miss Stafva on the veranda. They did not notice her. Ingrid saw with surprise that the round-backed old lady had something hidden under all her capes which looked like crape; it was put well up and carefully hidden. Ingrid had to look very closely before she discovered that they were two large bat's wings which she tried to hide. The young girl grew still more curious and tried to see her face, but she stood and looked into the yard, so it was impossible. So much, however, Ingrid did see when she put out her hand to the housekeeper--that one of her fingers was much longer than the others, and at the end of it was a large, crooked claw. 'I suppose everything is as usual here?' she said. 'Yes, honoured Mistress Sorrow,' said Miss Stafva. 'You have not planted any flowers, nor pruned any trees? You have not mended the bridge, nor weeded the avenue?' 'No, honoured mistress.' 'This is quite as it should be,' said the honoured mistress. 'I suppose you have not had the audacity to search for the vein of ore, or to cut down the forest which is encroaching on the fields?' 'No, honoured mistress.' 'Or to clean the wells?' 'No, nor to clean the wells.' 'This is a nice place,' said Mistress Sorrow; 'I always like being here. In a few years things will be in such a state that my birds can live all over the house. You are really very good to my birds, Miss Stafva.' At this praise the housekeeper made a deep curtsy. 'How are things otherwise at the house?' said Mistress Sorrow. 'What sort of a Christmas have you had?'
