A good, inexpensive, aud easily prepared lubricant for cycle chains is a mixture of plumbago and vaseline. Any good make of blacklead will do, but specially prepared plumbago is better. Crush the blacklead to a tine powder and mix thoroughly with twice the bulk of good vaseline and a little lubricating oil. As all these lubricants are very "dry," they must be applied about every fifty or hundred miles.
