She disappeared and, after a suitable time, reappeared at the window, presumably fully clothed. I detached the bell from my bed and sat with it in my hand, and I found afterward that she had done the same. From time to time we each gave the cord a slight, ecstatic pull. The whole mystery of the great night lay in those gentle signals.

It is unfortunate to have to confess that, after a time, the mystery palled. But it did. Stars, wide, dark, moonless lawn, empty street, all these blurred and merged in a single impression. This was one of chilliness. Even calling through the night at intervals, and at the imminent risk of being heard, lost its charm, because after a little while there was nothing left to call. “How still it is!” and “Nobody but us is up in town,” and “Won’t Delia be mad?” lose their edge when repeated for about the third time each. Moreover, I was obliged to face a new foe: I was getting sleepy.

Without undue disturbance of the cord, I managed to consult the clock once more. It was five minutes of four. There remained more than an hour to wait! It was I who capitulated.

“Mary Elizabeth,” I said waveringly, “would you care very much if I was to lay down just a little to rest my eyes?”

“No, I wouldn’t care,” came with significant alacrity. “I will, too.”

I lay down on the covers and pulled a comforter about me. As I drifted off I remember wondering how the dark ever kept awake all night. For it was awake. To know that one had only to listen.

We all had a signal which we called a “trill,” made by tongue and teeth, with almost the force of a boy and a blade of grass. This, produced furiously beneath my window, was what wakened me. Delia stood between the two houses, engaged with such absorption in manufacturing this sound that she failed to see me at the window. A moment after I had hailed her, Mary Elizabeth appeared at her window, looking distinctly distraught.

Seeing us fully dressed, Delia’s indignation increased.

“Why didn’t you leave me know you were up?” she demanded shrilly. “It’s a quarter past five. I been out here fifteen minutes.”

We were assuring her guiltily that we would be right down when there came an interruption.
