Dora was delighted with the invitation, for she had begun to be afraid that Paula did not mean to have anything to say to her, and yet she had been particularly attracted toward this quiet girl, so near her own age. Paula had wanted to see what sort of a girl Dora was, before she made advances, and she was evidently well pleased with what she saw, for she now took her new friend by the hand, and led her away down the garden path. The twins and Hunne, and even Rolf, were soon tired of waiting for Dora to come back, and went calling and searching everywhere for her; but they could not find her; she had quite disappeared. In fact, Paula had taken her all round the garden, and then up to her own room. There the two girls sat and talked, and talked, about all sorts of things. They told each other their thoughts and feelings on various subjects, and found themselves in perfect sympathy. It was a great happiness to both, for neither had ever had an intimate friend, of her own age, one whose tastes, purposes and ideals were like her own. "Now we will be 'best friends' forever," they said, and sat, forgetful of all the world besides, till the stars stood shining in the heavens above, and all the earth was bathed in shadow. The mother found them at last; she had suspected that they had taken refuge in Paula's room. Dora sprang up hastily when she noticed how dark it had grown, and recollected that her aunt would be expecting her. The other children were waiting below, rather a dissatisfied little party at Dora's disappearance; for they all wanted to talk to her. Rolf was particularly annoyed. "Why Dora," he said, "I thought you were going to guess my charade; will you try now?" But Dora said it was really time for her to go home; so Mrs. Birkenfeld told them that they must wait till to-morrow for all they had to say, and that Dora would come every day to see them and would take lessons with them too. This satisfied them, and they charged Dora to come very early and stay very late, for there was a great deal to do and a great deal to show her. The leave taking lasted a long time, but Rolf suddenly cut the thing short. He was going to have the last word with Dora, for he was to walk home with her. As they crossed the grass plot towards the cottage, the stars were shining so brightly overhead, that Dora stood still. "Look up, Rolf;" she said, "do you see those five twinkling stars up there? I know them very well; they were my own stars in Karlsruhe, and they are here with me too." "Oh yes, I've seen those; they are on our map of the Heavens. Do you know their names, Dora?" "No, indeed; can you tell the names of the stars Rolf? How much you do know!" said Dora admiringly. "Don't those five all belong together, and have one name? There are others too that look as if they belonged together. Do you know them all? How I should like to learn them from you!" Rolf was much pleased with the idea of giving lessons in astronomy, to one so eager to learn.
