Note 1 — Chapter IV · How They Invented Money.

That the inconveniences experienced by a community attempting to conduct its exchanges exclusively by pure and direct barter as here depicted, are not only not imaginary, but have their exact counterpart in the present every-day experiences of countries of great geographical area and population, is proved by the testimony of Barth, Burton, and other recent travelers in Eastern Africa. Thus Barth, for example, says (see “Travels,” vol. i., p. 568; vol. iii., p. 203) that he was repeatedly prevented from buying what he absolutely needed—corn, rice, etc.—because he did not have, and could not get, what the people wanted in exchange; and, again (vol. ii., p. 51), he states that so great was the difficulty of getting things in some of the African towns which he visited, in consequence of the people having no general medium of exchange, that his servants would often return from their purchasing expeditions in a state of the utmost exhaustion.
