"Harden," he said, "it's really very funny. It's infinitely humorous, isn't it?"

"I see nothing humorous in anything," I replied. "I've lost all sense of humour."

He raised his eyebrows.

"Of humour?" he queried. "Surely not. Humour is surely immortal."

CHAPTER XXX

THE GREAT SLEEP

On that day the animals in London fell asleep with few exceptions. The exceptions were, I believe, all dogs. I do not pretend to explain, how it came about that dogs remained awake longer than other animals. The reason may be that dogs have some quality in them which is superior even to the qualities found in man, for there is a sweetness in the nature of dogs that is rare in men and women.

Many horses were overcome in the streets and lay down where they were. No attempt was made to remove them. They were left, stretched out on their sides, apparently unconscious.

And many thousands of men and women fell asleep. In some cases men were overcome by the sleep before their dogs, which has always seemed strange to me. It was Thornduck who told me this, for he remained awake during this period that the germ reigned supreme. He tells me that I fell asleep the next evening in my chair in the study and that he carried me upstairs to my room. I had just returned from visiting Leonora, whom I had found unconscious. He made a tour of London next morning. In the City there was a profound stillness.
