In their early intercourse with Europeans the article that attracted most notice was iron. Its utility, in forming the instruments of war and husbandry, make it preferable to all others, and iron soon became the measure by which the value of all other commodities was ascertained. Thus, a certain quantity of goods, of whatever denomination, appearing to be equal in value to a bar of iron, constituted, in the traders’ phraseology, a bar of that particular merchandise. Twenty leaves of tobacco, for instance, were considered as a bar of tobacco; and a gallon of spirits (or rather half spirits and half water) as a bar of rum, a bar of one commodity being reckoned equal in value to a bar of another commodity. As, however, it must unavoidably happen that, according to the plenty or scarcity of goods at market in proportion to the demand, the relative value would be subject to continual fluctuation, greater precision has been found necessary; and at this time the current value of a single bar of any kind is fixed by the whites at two shillings sterling. Thus, a slave whose price is £15, is said to be worth 150 bars. In transactions of this nature it is obvious that the white trader has infinitely the advantage over the African, whom, therefore, it is difficult to satisfy, for conscious of his own ignorance, he naturally becomes exceedingly suspicious and wavering; and, indeed, so very unsettled and jealous are the negroes in their dealings with the whites, that a bargain is never considered by the European as concluded until the purchase money is paid and the party has taken leave. Having now brought together such general observations on the country and its inhabitants as occurred to me during my residence in the vicinity of the Gambia, I shall detain the reader no longer with introductory matter, but proceed, in the next chapter, to a regular detail of the incidents which happened, and the reflections which arose in my mind, in the course of my painful and perilous journey, from its commencement until my return to the Gambia.
