Indian trumpets
The botuto, which Gumilla saw used by some tribes near the river Orinoco (of which we engrave two examples), was evidently an ancient Indian contrivance, but appears to have fallen almost into oblivion during the last two centuries. It was made of baked clay and was commonly from three to four feet long: but some trumpets of this kind were of enormous size. The botuto with two bellies was usually made thicker than that with three bellies and emitted a deeper sound, which is described as having been really terrific. These trumpets were used on occasions of mourning and funeral dances. Alexander von Humboldt saw the botuto among some Indian tribes near the river Orinoco.
Peruvian bone pipe
M. de Castelnau in his “Expédition dans l’Amérique” gives among the illustrations of objects discovered in ancient Peruvian tombs a flute made of a human bone. It has four finger-holes at its upper surface and appears to have been blown into at one end. Two bone-flutes, in appearance similar to the engraving given by M. de Castelnau, which have been disinterred at Truxillo are deposited in the British museum. They are about six inches in length, and each is provided with five finger-holes. One of these has all the holes at its upper side, and one of the holes is considerably smaller than the rest. The specimen shown is ornamented with some simple designs in black.
Peruvian huayra-puhura
The British museum possesses a huayra-puhura consisting of fourteen reed pipes of a brownish colour, tied together in two rows by means of thread, so as to form a double set of seven reeds. Both sets are almost exactly of the same dimensions and are placed side by side. The shortest of these reeds measure three inches, and the longest six and a half. In one set they are open at the bottom, and in the other they are closed. Consequently, octaves are produced. The reader is probably aware that the closing of a pipe at the end raises its pitch an octave. Thus, in our organ, the so-called stopped diapason, a set of closed pipes, requires tubes of only half the length of those which constitute the open diapason, although both these stops produce tones in the same pitch; the only difference between them being the quality of sound, which in the former is less bright than in the latter.
