"'Whether my visible success reassured Mrs. Hill or not, I do not know, but anyhow she departed that night for Berlin, leaving us loaded with endless instructions, extra money, and a tiny red German dictionary. I never felt so officious in my life as when I called a cab and ushered Jess and Anne into it after the train had pulled out. I can see now why it is that Thomas Cook and Son have been so eminently successful. "'The next day we spent browsing around in the Cathedral. To describe it would be out of place in this letter, which deals primarily with adventure. I might say, however, that Jess bought all of you silver pendants of the Three Wise Men of Cologne, when she ought to have saved her money. That evening we took the Rhine-boat--the _Parsifal_ this time--and when we awoke in the morning we were well among the castles. It was a marvelous day, and I'll have loads to tell you about it in the fall. "'We reached Mayence in the evening in a pouring rain, and took a cab, driven by a funny, red-faced driver, to a hotel where English was spoken, for however Mrs. Hill may have been impressed by my honors in German she had taken care to recommend English hotels. Our train for Berlin was to leave at nine A.M., so we went to bed early, feeling too self-resourceful for words. "'Do you remember how, with cheers for St. Helen's and groans for Athens, we bequeathed Greenie to the Ancient World last winter? Who at that joyous moment would have thought that she would again and so soon enter our lives? Imagine then, if you can, the chill of horror which shook us all when upon alighting at the Mayence station the next morning, ready to take our train for Berlin, we beheld--_unmistakably beheld_--our beloved Greenie by the drinking-fountain!!! Her back was toward us, and all the proofs we had at that moment were the hang of her familiar gray suit, and our old friend, that absurd chicken feather, awry upon her little, black, St. Helen's hat. We stood breathless and surveyed her. "'"It is!" said Jess. "Let's run!" "'"It's not!" said Anne. "She's in Athens. Besides, she's too antiseptic to drink at a fountain!" "'"I believe it is," said I. "It's just as well to look for shelter!" "'"Of course, it is," said Jess. "That chicken-feather----" "'And just then she looked up! There was no longer any question as to identity. In spite of drinking-fountains and Athens, it was Greenie! She looked quite the same as ever, except for the absence of the gray shawl, and no visible effects of curl-papers. "'Whether it was Providence, Greenie's near-sightedness or our own speed that saved us, I don't know; but I do know we took her bearings and all ran in opposite directions. She was going through the door marked _South_. Anne accordingly ran north, Jess east, and I west. "'"Meet in five minutes at the fountain," I commanded hoarsely as we separated.
