The three slaves who accompanied me were now indispensable as interpreters. Apart from them I could have prevailed very little in overcoming the shyness and mistrust towards strangers which the natives continually exhibited: an exterior survey did not satisfy me, and I persevered till I gained admittance to the inside of several of the huts, so that I could institute a regular domestic investigation. Every corner was explored, and by this means many a strange implement was brought to light, and many an unexpected discovery revealed. The granaries of the Bongo were now quite full, as the harvest was just over: all was consequently mirth and riot in the district, and many a night’s rest did I find disturbed by the noisy orgies which re-echoed from the shadowy woods. At full blast for hours together were the long wooden trumpets, the loud signal-horns, the huge trombones, and those immense drums for the construction of which the strongest timber has been selected from the forests. The powers of shrieking were put forth to the uttermost. Like the rolling of the breakers of an angry sea, the noise rose and fell: alternate screechings and howlings reached my ears, and hundreds of men and women seemed to be trying which could scream the loudest. Incapable of closing an eye for sleep while such infernal outcry was around, I went several times to inspect the frantic scene of merriment. Nights when the moon was bright were those most frequently selected for the boisterous revelry; the excuse alleged being that the mosquitoes would not let them rest, and therefore it was necessary to dance; but in truth, there was no nuisance of flies here worth consideration: I was not annoyed to anything like the same extent as upon my backward journey on the White Nile.
