"And Joe stayed under water over three minutes," Helen said.
"Did I, really?" Joe cried.
"You certainly did."
"I was just giving myself a try-out," Joe explained to Benny.
"That's pretty good," declared the "human fish," as he tested the temperature of the water. "I couldn't do that at first."
"Oh, you see I've lived near the water all my life," Joe explained, "and it comes sort of natural to me. Don't be afraid that I'm going after your act though," he added, with a laugh.
"I almost wish you would," and Benny spoke wearily.
"What's the matter?" asked Helen, with ready sympathy.
"Oh, I don't know. I don't feel just right, somehow or other. It's mostly in my head—back here," and Benny pointed to the region just behind his ears. "I've got a lot of pain there, and going under water and staying so long seems to make it worse."
"Why don't you see a doctor?" asked Joe.
