"So we did. And we mean to write to each other, in the same style in which we used to talk; we agreed on that as we were saying good-bye. Our men, even your friends, are always so thoroughgoing. And you are the most thoroughgoing of all, which sometimes annoys me and puts me quite out of patience. And you must promise me that you will be more like Mr. Armstrong and try to talk a little more simply and amusingly and a little faster and not always on the same subject."

Botho promised to amend his ways, and as Katherine, who loved superlatives, after describing a phenomenally rich American, an absolutely albino Swede with rabbit's eyes, and a fascinating Spanish beauty--had closed with an afternoon excursion to Limburg, Oranienstein and Nassau, and had described to her husband in turn the crypt, the cadets' training school and the water-cure establishment, she suddenly pointed to the towers of the castle at Charlottenburg and said: "Do you know, Botho, we must go there to-day or to Westend or to Hallensee. The Berlin air is rather heavy and there is none of the breath of God in it, as there is in the country where the poets so justly praise it. And when one has just come back fresh from nature, as I have, one has learned to love once more what I might call purity and innocence. Ah, Botho, what a treasure an innocent heart is. I have fully determined to keep my heart pure. And you must help me. Yes, you must promise me. No, not that way; you must kiss me three times on my forehead like a bride. I want no tenderness, I want a kiss of consecration ... And if we take lunch, a warm dish, of course, we can get out there at about three."

And so they went on their excursion and although the air of Charlottenburg was still less like the breath of God than the Berlin air, yet Katherine was fully determined to stay in the castle park and to give up Hallensee. Westend was so tiresome and Hallensee was half a journey further, almost as far as Schlangenbad. But in the castle park one could see the mausoleum, where the blue lights were always so strangely moving, indeed she might say it was as if a bit of heaven had fallen into one's soul. That produced a thoughtful mood and led to pious reflections. And even if it were not for the mausoleum, still there was the bridge where you could see the carp, the bridge with the bell on it, and if a great big mossy carp came swimming by, it always seemed to her as if it were a crocodile. And perhaps there might be a woman there with round cakes and wafers, and one might buy some and so, in a small way, do a good work. She said a "good work" on purpose and avoided the word Christian, for Frau Salinger was always charitable.

And everything went according to the programme, and when the carps had been fed they both walked further into the park until they reached the Belvedere with its rococo figures and its historical associations. Katherine knew nothing of these associations and Botho therefore took occasion to tell her of the ghosts of the departed Emperor and Electors whom General von Bischofswerder caused to appear at this very place in order to arouse King Frederick William the Second from his lethargy, or what amounted to the same thing, to get him out of the hands of his lady love and bring him back to the path of virtue.

"And did it do any good?" asked Katherine.

"No."

"What a pity! Anything like that always moves me so painfully. And if I consider that the unhappy prince (for he must have been unhappy) was the father-in-law of Queen Luise then my heart bleeds. How she must have suffered! I can never rightly imagine such things in our Prussia. And you say Bischofswerder was the name of the general who caused the ghosts to appear?"

"Yes. At court they called him the tree toad."

"Because he brought on changes of weather?"

"No, because he wore a green coat."
