"And tell her to be quick about it," said Donald. "I'm starving!"

"As hungry as a sparrow," said Uncle Robert, smiling.

While they were eating, the twilight came on.

"Listen!" whispered Frank, as a queer, clucking sound was heard among
the bushes. Then came the cry:

"Whip-poor-will! whip-poor-will!"

"I wish I could see a whip-poor-will," said Donald. "They never let me
get near enough to them to see how they look."

"Let's try this one," said Frank. "It's very near."

On tiptoe they slipped off the porch, but the shy bird heard them and
flew away. Soon they heard it again:

"Whip-poor-will! whip-poor-will!"

And another one answered from the edge of the cornfield:

"Whip-poor-will! whip-poor-will!"
