"It is," said McKay coolly; "and the hairs of our head are numbered too!"
"So teach us to number our days," rejoined the voice from the fog, "that we may apply our hearts unto wisdom."
"The days of our years are three-score years and ten," said McKay.
"Have you a name?"
"A number."
"And what number will that be?"
"Sixty-seven. And yours?"
"You should know that, too."
"It's the reverse; seventy-six."
"It is that," said McKay. "Come in."
