weight. But in the Gambia trade as Moore described it the unit or "bar"
in rum, cloth and most other things became depreciated until in some
commodities it was not above a shilling's value in English money. Iron
itself, on the other hand, and crystal beads, brass pans and spreadeagle
dollars appreciated in comparison. These accordingly became distinguished
as the "heads of goods," and the inclusion of three or four units of them
was required in the forty or fifty bars of miscellaneous goods making up
the price of a prime slave.[11] In previous years grown slaves alone had
brought standard prices; but in Moore's time a specially strong demand for
boys and girls in the markets of Cadiz and Lisbon had raised the prices of
these almost to a parity. All defects were of course discounted. Moore, for
example, in buying a slave with several teeth missing made the seller abate
a bar for each tooth. The company at one time forbade the purchase of
slaves from the self-styled Portuguese because they ran the prices up; but
the factors protested that these dealers would promptly carry their wares
to the separate traders, and the prohibition was at once withdrawn.

The company and the separate traders faced different problems. The latter
were less easily able to adjust their merchandise to the market. A Rhode
Island captain, for instance, wrote his owners from Anamabo in 1736, "heare
is 7 sails of us rume men, that we are ready to devour one another, for our
case is desprit"; while four years afterward another wrote after trading
at the same port, "I have repented a hundred times ye lying in of them dry
goods", which he had carried in place of the customary rum.[12] Again, a
veteran Rhode Islander wrote from Anamabo in 1752, "on the whole I never
