Another job you wouldn't want to do: oil lamp cleaning
Eithne Farry, Karen Hurrell and Jon Sutherland. Snapshots in Time. 100 Years of Change. North Vancouver: Whitecap Books, 1998.
Anyone who's used oil lamps knows how black the chimneys get with soot. Hard to get your hand into those narrow confines to clean them thoroughly. But, unless you do, their light is significantly reduced. I can also attest, based on my experience during Ice Storm 98, that reading a book by lamplight is very hard on the eyes.
