On inquiring how it came to pass that the emperor of Melli, whom they represented as a powerful sovereign, did not find means, by friendship or force, to discover who these people were who would not suffer themselves to be seen or talked to, I was informed that this emperor, not many years ago, resolved to procure some of these invisible people, and held a council on the occasion, in which the following plan was devised and carried into execution.  Before the salt caravan returned the half days journey from their salt heaps, some of the emperors people made certain pits by the water side, and near the place where the salt was left, and when the negroes came to deposit their gold on the salt, those who were concealed in the pits attacked them suddenly and took four of them prisoners, all the rest making their escape.  Three of those who were thus taken were immediately set free by the captors, who judged that one would be quite sufficient to satisfy the curiosity of their emperor, and that the negroes would be the less offended.  But after all, the design proved abortive; for though spoken to in various languages, the prisoner would neither speak or take any victuals, and died at the end of four days.  On this account, the Melli negroes concluded that these other negroes were dumb; but others were of opinion, that being endowed with the human form, they must necessarily have the power of speech; but, that finding himself treated in this manner, so contrary to ancient custom, he refused to speak from indignation.  This untoward result was much regretted by the negroes of Melli, because it prevented them from gratifying the curiosity of their emperor; who, on being informed of this persons death, was much dissatisfied, yet asked what manner of men the prisoners were.  He was accordingly informed that they were of a deep black colour, well shaped, and a span taller than the natives of Melli.  That their under lip was thicker than a mans fist, of a very red colour, and hung down on their breasts, with something like blood dropping from it; but that their upper lips were small, like those of other men.  That the form of the under lip exposed their gums and teeth, which were larger than their own, having great teeth in each corner of their mouth, with large black eyes, and altogether a terrible appearance, as the gums dropped blood continually, as well as the great hanging under lip.

This cross accident prevented all the succeeding emperors of Melli from making any farther attempt of the kind; because, from that time, these negroes forbore, for three years, from coming to buy salt as usual.  It is believed that their lips began to putrify, through the excessive heat of the climate; and being no longer able to endure a distemper, of which some must have died for want of the effectual remedy which they had experienced from the use of salt, they returned of their own accord to traffic for that commodity in the old way.  All this has established an opinion
