Some one found out how to raise a swelling, and there was quite an epidemic of swollen wrists and ankles. A little lump of earth in a handkerchief, pounded gently on the place, for twenty minutes or so, will bring the desired result. Soap-pills will raise the temperature. Tobacco, eaten, will derange the heart. These are well-known methods of achieving sick-leave. I had a way all my own.
