What were the attempts made by the Canterville Ghost to scare the Otis family?

The Canterville Ghost first decides to reapply the blood stain that the Otis family has removed from the carpet. This happens three times, and then the ghost appears in chains to menace Mr. Otis. In response, Mr. Otis tells him to oil his chains. In the meantime, the blood stains keep reappearing on the floor. Then, the ghost knocks over an old suit of armor and sits upon the high-backed chair. However, the twins shoot at him, and then the ghost decides to rig up another ghost to scare the Otis children. They disassemble the other ghost, and the Canterville Ghost decides to become the "Headless Earl" to scare the Otis twins once and for all. Unfortunately for the ghost, the twins greet him by rigging up a pitcher to pour water on his head, and he takes to his bed with a bad cold, disheartened about his ability to scare the Otis family.
