They wore old serge skirts and jerseys that they could not spoil.

This tree made a splendid arbour, or house with a suite of rooms. Lottchen sat up in the branches like a little bird, and like a little bird she sang all the songs she knew. From this tree you could see the mountain called the Stellerskuppe and the blue sky through the tree-stems on the summit. At sunset time, the sky behind the trees turned a golden colour, till it looked like a picture of fairyland.

It was a fine view, but still you could not see from here the famous oak-tree, where the little green tree man lived. This was ten minutes' walk from the farm.

Trudel and Lottchen saw him first on a wet day when they had set out for a walk in spite of the rain, with their green waterproof cloaks on with hoods over their heads, looking for all the world like wood-goblins themselves. They were walking down a narrow green path, and mother was some distance behind.

"Do just look, Trudel," said Lottchen. "I believe there is a little man in that hollow tree!"

"So there is, he is smiling and bowing to us, let's go and visit him," said Trudel, always enterprising.

Lottchen hung back, feeling a little afraid; she was always on the look-out for the unexpected, and yet was surprised when something really happened.

"Come along, darling," said Trudel, grasping her smaller sister by the hand.

They both distinctly saw the little man; they said they could have drawn him afterwards, and indeed they attempted to do so as well as they could. But as they approached the venerable oak, the little man vanished, and all they saw was a strange green stain on the inside of the tree, resembling a dwarf with a peaked hood on.

"Just look at this Gothic window," said Lottchen, proud of her knowledge of the word "Gothic." "How nicely this tree-room is carved. I am sure he lives here; where are his little chairs and tables? I should love to see them."
