“Not at all,” said Mr. Twist.

Anna-Felicitas persisted.  “In view of the facts,” she said gently, “I’m afraid your denial carries no weight.”

“The facts,” said Mr. Twist, taking up his teapot and examining it with care, “are that I’m coming with you.”

“Oh are you,” said Anna-Felicitas much more briskly; and it was here that Anna-Rose’s eyes dried up.

“That rather dishes your theory,” said Mr. Twist, still turning his teapot about in his hands.  “Or would if it didn’t happen that I—­well, I happen to have some business to do in California, and I may as well do it now as later.  Still, I could have gone by a different route or train, so you see your theory is rather dished, isn’t it?”

“A little,” admitted Anna-Felicitas.  “Not altogether.  Because if you really like our being here, here we are.  So why hurry us off somewhere else so soon?”

Mr. Twist perceived that he was being led into controversy in spite of his determination not to be.  “You’re very wise,” he said shortly, “but you don’t know everything.  Let us avoid conjecture and stick to facts.  I’m going to take you to California, and hand you over to your friends.  That’s all you know, and all you need to know.”

“As Keats very nearly said,” said Anna-Rose

“And if our friends have run away?” suggested Anna-Felicitas.

“Oh Lord,” exclaimed Mr. Twist impatiently, putting the teapot down with a bang, “do you think we’re running away all the time in America?”

“Well, I think you seem a little restless,” said Anna-Felicitas.

Thus it was that two hours later the twins found themselves at the Clark station once more, once more starting into the unknown, just as if they had never done it before, and gradually, as they adapted themselves to the sudden change, such is the india-rubber-like quality of youth, almost with the same hopefulness.  Yet they couldn’t but meditate, left alone on the platform while Mr. Twist checked the baggage, on the mutability of life.  They seemed to live in a kaleidoscope since the war began what a series of upheavals and readjustments had been theirs!  Silent, and a little apart on the Clark platform, they reflected retrospectively; and as they counted up their various starts since the days, only fourteen months ago, when they were still in their home in Germany, apparently as safely rooted, as unshakably settled as the pine trees in their own forests, they couldn’t but wonder at the elusiveness of the unknown, how it wouldn’t let itself be caught up with and at the trouble it was giving them.
