There can be no such thing as "tainted money." Money bears no taint. It serves the murderer and the saint with equal indifference. It is a tool. It can be used one day for a crime, the next day for the most beneficent purpose. No use leaves any mark on it. The Solomon Islanders are expert merchants and "are fully the equal of white men in cheating."[365] They do it with shell money as whites do it with gold, silver, and banknotes. That is to say, the "money" is indifferent because it has no ethical function at all and absolutely no character. +156.+ There are other topics which might be brought under the struggle for existence as a cluster of folkways, with great advantage. The struggle for existence takes on many different forms and produces phenomena which are cases of folkways. It speedily develops industrial organization, which, in one point of view, is only the interaction of folkways. Weights and measures, the measurement of time, the communication of intelligence, and trade are primary folkways in their earliest forms and deserve careful study as such.
