He awaked on the morning of the twenty-second with a pain in his left wrist, and saw that his cuff was brown with dried blood. His recollections were very confused, but the scene with the black man in the unknown space stood out vividly. The rats must have bitten him as he slept, giving rise to the climax of that frightful dream. Opening the door, he saw that the flour on the corridor floor was undisturbed except for the huge prints of the loutish fellow who roomed at the other end of the garret. So he had not been sleep-walking this time. But something would have to be done about those rats. He would speak to the landlord about them. Again he tried to stop up the hole at the base of the slanting wall, wedging in a candlestick which seemed of about the right size. His ears were ringing horribly, as if with the residual echoes of some horrible noise heard in dreams.
