As appeals, however, to the sense of sound, the great festivals of the Bongo abound with measures much more thrilling than any of these minor performances. On those occasions the orchestral results might perhaps be fairly characterised as cat’s music run wild. Unwearied thumping of drums, the bellowings of gigantic trumpets, for the manufacture of which great stems of trees come into requisition, interchanged by fits and starts with the shriller blasts of some smaller horns, make up the burden of the unearthly hubbub which re-echoes miles away along the desert. Meanwhile, women and children by the hundred fill gourd-flasks with little stones, and rattle them as if they were churning butter: or again, at other times, they will get some sticks or dry faggots and strike them together with the greatest energy. The huge wooden tubes which may be styled the trumpets of the Bongo are by the natives themselves called “manyinyee;” they vary from four to five feet in length, being closed at the extremity, and ornamented with carved work representing a man’s head, which not unfrequently is adorned with a couple of horns. The other end of the stem is open, and in an upper compartment towards the figure of the head is the orifice into which the performer blows with all his might. There is another form of manyinyee which is made like a huge wine-bottle; in order to play upon it, the musician takes it between his knees like a violoncello, and when the build of the instrument is too cumbrous, he has to bend over it as it lies upon the ground. Little difference can be noticed between the kettle-drums of the Bongo and those of most other North African negroes. A section is cut from the thick stem of a tree, the preference being given to a tamarind when it can be procured; this is hollowed out into a cylinder, one end being larger than the other. The ends are then covered with two pieces of goat-skin stripped of the hair, which are tightly strained and laced together with thongs. At the nightly orgies a fire is invariably kept burning to dry the skin and to tighten it when it has happened to become relaxed by the heavy dews. A great number of signal-horns may be seen made from the horns of different antelopes; these are called “mangoal,” and have three holes like small flutes, and in tone are not unlike fifes. There is one long and narrow pipe cut by the Bongo out of wood which they call a “mburrah,” and which has a widened air-chamber close to the mouth-piece, very similar to the ivory signal-horns which are so frequently to be seen in all the negro countries.
