The other has four holes at its upper side and one underneath, the latter being placed near to the end at which the instrument evidently was blown. In the aperture of this end some remains of a hardened paste, or resinous substance, are still preserved. This substance probably was inserted for the purpose of narrowing the end of the tube, in order to facilitate the producing of the sounds. The same contrivance is still resorted to in the construction of the bone flutes by some Indian tribes in Guiana. The bones of slain enemies appear to have been considered especially appropriate for such flutes. The Araucanians having killed a prisoner, made flutes of his bones, and danced and “thundered out their dreadful war songs, accompanied by the mournful sounds of these horrid instruments.” Alonso de Ovalle says of the Indians in Chili: “Their flutes, which they play upon in their dances, are made of the bones of the Spaniards and other enemies whom they have overcome in war. This they do by way of triumph and glory for their victory. They make them likewise of bones of animals; but the warriors dance only to the flutes made of their enemies.” The Mexicans and Peruvians obviously possessed a great variety of pipes and flutes, some of which are still in use among certain Indian tribes. Those which were found in the famous ruins at Palenque are deposited in the museum in Mexico. They are:――The _cuyvi_, a pipe on which only five tones were producible; the _huayllaca_, a sort of flageolet; the _pincullu_, a flute; and the _chayna_, which is described as “a flute whose lugubrious and melancholy tones filled the heart with indescribable sadness, and brought involuntary tears into the eyes.” It was perhaps a kind of oboe. The Peruvians had the syrinx, which they called _huayra-puhura_. Some clue to the proper meaning of this name may perhaps be gathered from the word _huayra_, which signifies “air.” The _huayra-puhura_ was made of cane, and also of stone. Sometimes an embroidery of needlework was attached to it as an ornament. One specimen which has been disinterred is adorned with twelve figures precisely resembling Maltese crosses. The cross is a figure which may readily be supposed to suggest itself very naturally; and it is therefore not so surprising, as it may appear at a first glance, that the American Indians used it not unfrequently in designs and sculptures before they came in contact with Christians.
