The notion that the value of a thing bears any necessary relation to the
amount of labour (average or otherwise) bestowed upon it, is a fallacy
which needs no further refutation than it has already received. The
average amount of labour bestowed upon warming-pans confers no value
upon them in the eyes of a Gold-Coast negro; nor would an Esquimaux give
a slice of blubber for the most elaborate of ice-machines.
