“This is different,” she said.

“Yes; this is the real open air,” said the Terror.

“But I do get lots of open air,” protested the princess. “Why, I sleep with my window open—at least that much.” She held out her two forefingers some six inches apart. “The baroness did not like it. She said it was very dangerous and would give me the chills. But Doctor Arbuthnot said that it must be open. I think I sleep better.”

“We have our bedroom windows as wide open as they’ll go; and then they’re not wide enough in this hot weather,” said Erebus in the tone of superiority that was beginning to sound galling.

“I think if you took off your hat and jacket, you’d be cooler still,” said the Terror rather quickly.

The princess hesitated a moment; then obediently she took off her hat and jacket, and breathed another soft sigh of pleasure. She had quite lost her air of discomfort and boredom. Her eyes were shining brightly; and her pale cheeks were a little flushed with the excitement of her situation.

It is by no means improbable that the Twins, as well-brought-up children, were aware that it is not etiquette to speak to royal personages unless they first speak to you. If they were, they did not let that knowledge stand in the way of the gratification of their healthy curiosity. It may be they felt that in the free green wood the etiquette of courts was out of place. At any rate they did not let it trammel them; and since their healthy curiosity was of the liveliest kind they submitted the princess to searching, even exhaustive, interrogation about the life of a royal child at a German court.

They questioned her about the hour she rose, the breakfast she ate, the lessons she learned, the walks she took, the lunch she ate, the games she played, her afternoon occupations, her dolls, her pets, her tea, her occupations after tea, her dinner, her occupations after dinner, the hour she went to bed.

There seemed nothing impertinent in their curiosity to the princess; it was only natural that every detail of the life of a person of her importance should be of the greatest interest to less fortunate mortals. She was not even annoyed by their carelessness of etiquette in not waiting to be spoken to before they asked a question. Indeed she enjoyed answering their questions very much, for it was seldom that any one displayed such a genuine interest in her; it was seldom, indeed, that she found herself on intimate human terms with any of her fellow creatures. She had neither brothers nor sisters; and she had never had any really sympathetic playmates. The children of Cassel-Nassau were always awed and stiff in her society; their minds were harassed by the fear lest they should be guilty of some appalling breach of etiquette. The manner of the Twins, therefore, was a pleasant change for her. They were polite, but quite unconstrained; and the obsequious people by whom she had always been surrounded had never displayed that engaging quality, save when, like the baroness, they were safely asleep in her presence.

But her account of her glories did not have the effect on her new friends she looked for. As she exposed more and more of the trammeling net of etiquette in which from her rising to her going to bed she was enmeshed, their faces did not fill with the envy she would have found so natural on them; they grew gloomy.
