My body shone so brightly in the sun that I felt very proud of it and it did not matter now if my axe slipped, for it could not cut me. There was only one danger–that my joints would rust; but I kept an oil-can in my cottage and took care to oil myself whenever I needed it. However, there came a day when I forgot to do this, and, being caught in a rainstorm, before I thought of the danger my joints had rusted, and I was left to stand in the woods until you came to help me. It was a terrible thing to undergo, but during the year I stood there I had time to think that the greatest loss I had known was the loss of my heart. While I was in love I was the happiest man on earth; but no one can love who has not a heart, and so I am resolved to ask Oz to give me one. If he does, I will go back to the Munchkin maiden and marry her.
