"Well, we're here," remarked the Very Young Man. "Everything's O.K. so far. Let's get right around after that scratch."

"Keep together," cautioned the Doctor, and they started off along the path, following its inner edge.

As they progressed, the top of the ring steadily became broader; the surface underfoot became rougher. The Big Business Man, walking nearest the edge, pulled his companion towards him. "Look there!" he said. They stood cautiously at the edge and looked down.

Beneath them the ring bulged out. Over the bulge they could see the black of the handkerchief—a sheer hundred-feet drop. The ring curved sharply to the left; they could follow its wall all the way around; it formed a circular pit some two hundred and fifty feet in diameter.

A gentle breeze fanned their faces as they walked. The Very Young Man looked up into the gray of the distance overhead. A little behind, over his shoulder he saw above him in the sky a great, gleaming light many times bigger than the sun. It cast on the ground before him an opaque shadow, blurred about the edges.

"Pretty good day, at that," remarked the Very Young Man, throwing out his chest.

The Doctor laughed. "It's half-past eight at night," he said. "And if you'll remember half an hour ago, it's a very stormy night, too."

The Big Business Man stopped short in his walk. "Just think," he said pointing up into the gray of the sky, with a note of awe in his voice, "over there, not more than fifteen feet away, is a window, looking down towards the Gaiety Theater and Broadway."

The Very Young. Man looked bewildered. "That window's a hundred miles away," he said positively.

"Fifteen feet," said the Big Business Man. "Just beyond the table."
