Tonsilitis
Apply kerosene freely on the outside of the neck. Also apply it inside with a small syringe, or a swab made by tying a soft bit of cloth on the end of a stick. A piece of smoked bacon tied on the neck when retiring for the night is a good remedy when applied in time.

Sore Throat
Slice a thin piece of old smoked bacon, the older the better. Stitch this to a piece of flannel and make it black with pepper. Warm it and fasten closely around the throat. Do not remove until the inflammation has been drawn to the outside. When the meat is taken off anoint the throat with a good vaseline and bind up in flannel which must be left on until the throat is entirely well.
