"Oh, no!" cried Hildegarde. "Please don't! It is I who must thank you and the children and all. I wish Rose—I wish my friend had come. She would have known; she would have said just the right thing to each one. Next time I shall bring her."

But "Nein! Müssen selbst kommen!" cried Fritzerl; and "You come, Lady!" shouted all the others. And as Hildegarde passed back through the long room where the sick children lay, Benny woke from his nap, and shouted, "Sing-girl! my sing-girl! come back soon!"

So, half laughing and half crying, Hildegarde passed out, her heart very full of painful pleasure.


CHAPTER X.

THE HOUSE IN THE WOOD.

Rose was wonderfully better. Every day in the clear, bracing air of Bywood seemed to bring fresh vigor to her frame, fresh color to her cheeks. She began to take regular walks, instead of strolling a little way, leaning on her friend's stronger arm. Together the girls explored all the pleasant places of the neighborhood, which were many; hunted for rare ferns, with tin plant-boxes hanging from their belts, or stalked the lonely cardinal-flower, as it nodded over some woodland brook. Often they took the little boat, and made long expeditions down the pleasant river,—Hildegarde rowing, Rose couched at her ease in the stern. Once they came to the mouth of a stream which they pleased themselves by imagining to be unknown to mankind. Dipping the oars gently, Hildegarde drew the boat on and on, between high, dark banks of hemlock and pine and white birch. Here were cardinal-flowers, more than they had ever seen before, rank behind rank, all crowding down to the water's edge to see their beauty mirrored in the clear, dark stream. They were too beautiful to pick. But Hildegarde took just one, as a memento, and even for that one the spirit of the enchanted place seemed to be angered; for there was a flash of white barred wings, a loud shrill cry, and they caught the gleam of two fierce black eyes, as something whirred past them across the stream, and vanished in the woods beyond.

"Oh! what was it?" cried Hildegarde. "Have we done a dreadful thing?"

"Only a kingfisher!" said Rose, laughing. "But I don't believe we ought to have picked his flower. This is certainly a fairy place! Move on, or he may cast a spell over us, and we shall turn into two black stones."

One day, however, they had a stranger adventure than that of the Halcyon Stream, as they named the mysterious brook. They had been walking in the woods; and Rose, being tired, had stopped to rest, while Hildegarde pursued a "yellow swallow-tail" among the trees. Rose established herself on the trunk of a fallen tree, whose upturned roots made a most comfortable armchair, all tapestried with emerald moss. She looked about her with great content; counted the different kinds of moss growing within immediate reach, and found six; tried to decide which was the prettiest, and finding this impossible, gave it up, and fell to watching the play of the sunshine as it came twinkling through the branches of oak and pine. Green and gold!—those were the colors the fairy princes always wore, she thought. It was the most perfect combination in the world; and she hummed a verse of one of Hildegarde's ballads:—
