“Yes, sir,” she answered with some hesitation; “if I don’t be sick when they’re here, and if I may sit on your knee sometimes.”

“Indeed you may,” he said; “and papa will try to take care that his feeble little girl has nothing to tire her.”

“No, she needn’t entertain,” said Lulu; “I can do it for both of us. Oh it is so nice, so nice, so perfectly splendid, to think we’re going to have a real party of our own for several days together!” she cried, again clapping her hands, jumping, dancing and pirouetting round the room.

Grace laughed at the sight, and so did their father.

“Why, Lulu, daughter,” he said, “you seem to be going quite wild over the prospect! I am very glad indeed to have hit upon something that gives you such pleasure. But come here; I have something more to tell you about it.”

“Oh, have you, papa?” she cried, running to him to put her arm round his neck and kiss him again and again; “what is it?”

“Ah,” he returned, laughing, “I doubt if it is well to tell you; you are so nearly crazy already.”

“Oh, yes, do tell me please. I won’t get any crazier; at least I don’t think I shall, I’ll try not to.”

So he told her of Zoe’s suggestion, and that he intended it should be carried out.

A conservatory opened from one of the parlors, and there, he said, they would have the magic cave.
