Streams may produce delightful tones. Thus one observer (at Yellowstone) tells of the "mysterious music of the distant falls" "like the tremulous vibration of a mighty but remote harp-string." (note 24) If falling water under certain peculiar acoustic circumstances can produce notes like those struck off from harp-strings, the tones can also be compared to those of lutes or lyres (for all are stringed instruments.) The very volume which places lutes and lyres in the Great Canyon, also tells of a forest elsewhere, which is a "Forest of Lutes and Lyres" (note 25.) Of course sounds merely resembling those of the stringed instruments, are here referred to. A forest is composed of trees rather than musical instruments, but it may produce musical tones like those of Lutes and Lyres. And similarly the notes arising from the Grand Canyon may be of a lute-like character. This is the teaching of the Ancients. We have found the Bottomless stream and it is certain that visitors should return with accounts of melody arising from the Canyon. Future explorers should listen for musical notes. They will certainly not be disappointed. One visitor says: "The waters waltz their way through the Canyon, making their own rippling, rushing, roaring music." We further read of innumerable cascades adding their wild music to the roar of the river." What are these innumerable cascades but the strings of the Lute which was heard ages ago by enraptured ears and which has kept on resounding ever since. The concert in the Canyon drowns even the basic roar of the river. The music is there. "We sit on some overhanging rocks, and enjoy the scene for a time, listening to the music of falling waters away up the canyons." (n. 26.) It appears that the acoustic properties of the Grand Canyon are calculated to produce most notable effects: "Great hollow domes are seen in the eastern side of the rock.... Our words are repeated with startling clearness, but in a soft mellow tone, that transforms them into magical music." Elsewhere an immense grotto "was doubtless made for an academy of =music= by its storm born architect; so we name it =Music= Temple." (n. 27.) Lutes and Lyres are there, say the Ancients. A Temple of Music is there, say the Moderns.
