On his way back from Mossi country in 1888, Louis Binger visited Bonduku, principal town of the Akan state of Gyaman. Commenting erroneously on the city's antiquity, Binger nonetheless appropriately referred to Bonduku's association with gold mining and the gold trade with nearby towns such as Kong and Buna. The town's more distant trading partners, he continiued, included Jenne and other Niger bend towns. In effect, the saltgold trade, to which Binger was referring, extended from the Taghaza mines in the north (northern Mali, two day's journey from Taodeni), to the southerly mines in the Bonduku and Asante regions. On his own admission, Binger obtained little information on the gold trade which, of the “hidden” variety, was conducted in traders' homes. He learned even less about gold mining. Even his own attempts to purchase a large gold nugget of 150 grams foundered on his host's opposition, claiming that the sale would bring misfortune to the peoples and their communities.
Misinformed on the city's age and frustrated in further endeavors, Binger nonetheless affirmed that a great deal of gold was in the city. He noticed, for example, that gold was the “almost exclusive” payment for European merchandise abounding in local markets. “Not a day passes,” he continued, but that commercial transactions--at his host's residence, or at any other house chosen at random--were concluded, involving gold as the exchange medium. Bonduku's inhabitants, moreover, adorned themselves with gold. Taxes were paid in gold.
