He broke off his speech suddenly and listened. From a distance came the mournful howl of a dog. It was answered in a moment by another howl from a different direction. Dog after dog took up the chorus until the air was filled with the melancholy wailing of the animals.
"See, Bolton," remarked the Doctor, "even the dogs feel the chastening influence of the Lady of Night and repent of the sins of their youth and the follies of their manhood, or should one say doghood? Come along. I feel that the call of duty must tear us away from the contemplation of the beauties of nature."
He led the way to Bolton's car and got in without further words. A half-hour later, Bolton led the way into the White House. A word to the secret service operative on guard at the door admitted him and his party, and he led the way to the newly constructed solarium where the President slept. An operative stood outside the door.
"What word, Brady?" asked Bolton in a whisper.
"He seems worse, sir. I doubt if he has slept at all. Admiral Clay has been in several times, but he didn't do much good. There, listen! The President is getting up again."
From behind the closed door which confronted them came sounds of a person rising from a bed and pacing the floor, slowly at first, and then more and more rapidly, until it was almost a run. A series of groans came to the watchers and then a long drawn out howl. Bolton shuddered.
"Poor devil!" he muttered.
Dr. Bird shot a quick glance around.
"Where is Admiral Clay?" he asked.
