“I think we’ll stop,” said Mrs. Brent to her companion. “It’s cool enough here under the trees.”

She fell into a listening attitude:

“Did you hear that bird-call?”

Mrs. Tuxford strained her ears, but heard nothing. Mrs. Brent excused herself with a gesture:

“I always forget that my hearing is sharp. Can’t you even hear those people talking over there? Sound carries far across water.”

Again Mrs. Tuxford listened intently.

“Nothing but a murmur,” she said.

Mrs. Brent held up a finger.

“There! That bird-call . . . lovely. Do you mind if I listen to it?”

Mrs. Tuxford nodded acquiescence and watched her companion listening intently to something which she herself could not catch. Her eyes wandered to the two figures across the Pool; but they were standing half in the shadows and she could make very little of them.
