It seemed a case of 'in for a penny, in for a pound.' Having made themselves so much at home, the children felt inclined to go a little farther. They had soon climbed the tiny staircase and were rewarded for their labour by finding two little bed-rooms, furnished just alike, and though neat and exquisitely clean, as plain and simple as the kitchen. 'Really, Rollo,' said Maia, 'this house might have been built by the fairies for us two, and see, isn't it odd? the beds are quite small, like ours. I don't know where the big person sleeps whom the arm-chair and the big cup downstairs are for.' 'Perhaps there's another room,' said Rollo, but after hunting about they found there was nothing more, and they came downstairs again to the kitchen, more puzzled than ever as to whom the queer little house could belong to. 'We'll come back again, the very first day we can,' said Maia, 'and tell the people about having taken the milk,' and then they left the cottage, carefully closing the door and gate behind them, and made their way back to where they had left Nanni. It took them longer than they had expected--either they mistook their way, or had wandered farther than they had imagined. But Nanni had suffered no anxiety on their account, for, even before they got up to her, they saw that she was enjoying a peaceful slumber. 'Poor thing!' said Maia. 'She must be very tired. I never knew her so sleepy before. Wake up, Nanni, wake up,' she went on, touching the maid gently on the shoulder. Up jumped Nanni, rubbing her eyes, but looking nevertheless very awake and good-humoured. 'Such a beautiful sleep as I've had, to be sure,' she exclaimed. 'Then you haven't been wondering what had become of us?' said Rollo. 'Bless you, no, sir,' replied Nanni. 'You haven't been very long away, surely? I never did have such a beautiful sleep. There must be something in the air of this forest that makes one sleep. And such lovely dreams! I thought I saw a lady all dressed in green--dark green and light green,--for all the world like the fir-trees in spring, and with long light hair. She stooped over me and smiled, as if she was going to say something, but just then I awoke and saw Miss Maia.' 'And what do you think _we've_ seen?' said Maia. 'The dearest little cottage you can fancy. Just like what Rollo and I would like to live in all by ourselves. And there was nobody there; wasn't it queer, Nanni?' Nanni was much impressed, but when she had heard all about the children's adventure she grew a little frightened. 'I hope no harm will come of it,' she said. 'If it were a witch's cottage;' and she shivered. 'Nonsense, Nanni,' said Rollo; 'witches don't have cottages like that,--all so bright and clean, and delicious new milk to drink.' But Nanni was not so easily consoled. 'I hope no harm may come of it,' she repeated.
