Of the operations on the Gambia an intimate view may be had from the journal of Francis Moore, a factor of the Royal African Company from 1730 to 1735.[8] Here the Jolofs on the north and the Mandingoes on the south and west were divided into tribes or kingdoms fronting from five to twenty-five leagues on the river, while tributary villages of Arabic-speaking Foulahs were scattered among them. In addition there was a small independent population of mixed breed, with very slight European infusion but styling themselves Portuguese and using a "bastard language" known locally as Creole. Many of these last were busy in the slave trade. The Royal African headquarters, with a garrison of thirty men, were on an island in the river some thirty miles from its mouth, while its trading stations dotted the shores for many leagues upstream, for no native king was content without a factory near his "palace." The slaves bought were partly of local origin but were mostly brought from long distances inland. These came generally in strings or coffles of thirty or forty, tied with leather thongs about their necks and laden with burdens of ivory and corn on their heads. Mungo Park when exploring the hinterland of this coast in 1795-1797, traveling incidentally with a slave coffle on part of his journey, estimated that in the Niger Valley generally the slaves outnumbered the free by three to one.[9] But as Moore observed, the domestic slaves were rarely sold in the trade, mainly for fear it would cause their fellows to run away. When captured by their master's enemies however, they were likely to be sent to the coast, for they were seldom ransomed.

The diverse goods bartered for slaves were rated by units of value which varied in the several trade centers. On the Gold Coast it was a certain length of cowrie shells on a string; at Loango it was a "piece" which had the value of a common gun or of twenty pounds of iron; at Kakongo it was twelve- or fifteen-yard lengths of cotton cloth called "goods";[10] while on the Gambia it was a bar of iron, apparently about forty pounds in 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 had so much trouble in all my voiges", and particularized as follows: "I have Gott on bord 61 Slaves and upards of thirty ounces of Goold, and have Gott 13 or 14 hhds of Rum yet Left on bord, and God noes when I shall Gett Clear of it ye trade is so very Dull it is actuly a noof to make a man Creasey my Cheef mate after making foor or five Trips in the boat was taken Sick and Remains very bad yett then I sent Mr. Taylor, and he got not well, and three more of my men has [been] sick….

The separate traders also had more frequent quarrels with the natives. In 1732 a Yankee captain was killed in a trade dispute and his crew set adrift. Soon afterward certain Jolofs took another ship's officers captive and required the value of twenty slaves as ransom. And in 1733 the natives at Yamyamacunda, up the Gambia, sought revenge upon Captain Samuel Moore for having paid them in pewter dollars on his previous voyage, and were quieted through the good offices of a company factor.[14] The company suffered far less from native disorders, for a threat of removing its factory would bring any chief to terms. In 1731, however, the king of Barsally brought a troop of his kinsmen and subjects to the Joar factory where Moore was in charge, got drunk, seized the keys and rifled the stores.[15] But the company's chief trouble was with its own factors. The climate and conditions were so trying that illness was frequent and insanity and suicide occasional; and the isolation encouraged fraudulent practices. It was usually impossible to tell the false from the true in the reports of the loss of goods by fire and flood, theft and rapine, mildew and white ants, or the loss of slaves by death or mutiny. The expense of the salary list, ship hire, provisions and merchandise was heavy and continuous, while the returns were precarious to a degree. Not often did such great wars occur as the Dahomey invasion of the Whidah country in 1726[16] and the general fighting of the Gambia peoples in 1733-1734[17] to glut the outward bound ships with slave cargoes. As a rule the company's advantage of steady markets and friendly native relations appears to have been more than offset by the freedom of the separate traders from fixed charges and the necessity of dependence upon lazy and unfaithful employees.
