It was said about five-and-twenty or thirty years ago that an adventurous trader, hearing from some natives in the territory that lies at the back of Quilimane, the legend of a great treasure buried in or about the sixteenth century by a party of Portuguese who were afterwards massacred, as a last resource attempted its discovery by the help of a mesmerist. According to this history the child who was used as a subject in the experiment, when in a state of trance, detailed the adventures and death of the unhappy Portuguese men and women, two of whom leapt from the point of a high rock into the Zambesi. Although he knew no tongue but English, this clairvoyant child is declared to have repeated in Portuguese the prayers these unfortunates offered up, and even to have sung the very hymns they sang. Moreover, with much other detail, he described the burial of the great treasure and its exact situation so accurately that the white man and the mesmerist were able to dig for and find the place where it had been - for the bags were gone, swept out by the floods of the river.
