"To stop it!" I cried. "I am perfectly desperate; I shall give her fair warning to-day, and the next time will be the last."

"Do nothing rash," said he.

"Rash!" I cried. "The only rash thing is that I should postpone it another hour." With that I rushed to my room, and here I am on the eve of what may be the great crisis of my life. I shall start at once. I have gained one thing to-day, for I have made one man, at least, realize the truth of this monstrous experience of mine. And, if the worst should happen, this diary remains as a proof of the goad that has driven me.

Evening. When I came to Wilson's, I was shown up, and found that he was sitting with Miss Penclosa. For half an hour I had to endure his fussy talk about his recent research into the exact nature of the spiritualistic rap, while the creature and I sat in silence looking across the room at each other.

I strode across and shook her roughly by the shoulder "As sure as there is a God in heaven, I swear that if you try another of your deviltries upon me I will have your life for it. Come what may, I will have your life. I have come to the end of what a man can endure."

"Accounts are not quite settled between us," said she, with a passion that equalled my own. "I can love, and I can hate. You had your choice. You chose to spurn the first; now you must test the other. It will take a little more to break your spirit, I see, but broken it shall be. Miss Marden comes back to-morrow, as I understand."

"What has that to do with you?" I cried. "It is a pollution that you should dare even to think of her. If I thought that you would harm her----"
