Removing Granulations from the Eye

Take a stick of tag-alder about two feet long, boring a hole nearly through the middle of the stick, filling it with salt, and plugging it up; then put one end into the fire and char it nearly to the salt, then the other end the same way, and finally pulverizing and applying the salt, the same as the above, once daily only.
