drowsy and deliberate in their movements when observed from a distance
of a mile or two. The heads of these comet-like masses are composed of
nearly solid water, and are dense white in color like pressed snow, from
the friction they suffer in rushing through the air, the portion worn
off forming the tail between the white lustrous threads and films of
which faint, grayish pencilings appear, while the outer, finer sprays of
water-dust, whirling in sunny eddies, are pearly gray throughout. At the
bottom of the fall there is but little distinction of form visible. It
is mostly a hissing, clashing, seething, upwhirling mass of scud and
spray, through which the light sifts in gray and purple tones while
at times when the sun strikes at the required angle, the whole wild
and apparently lawless, stormy, striving mass is changed to brilliant
rainbow hues, manifesting finest harmony. The middle portion of the
fall is the most openly beautiful; lower, the various forms into which
the waters are wrought are more closely and voluminously veiled, while
higher, towards the head, the current is comparatively simple and
undivided. But even at the bottom, in the boiling clouds of spray,
there is no confusion, while the rainbow light makes all divine, adding
glorious beauty and peace to glorious power. This noble fall has far the
richest, as well as the most powerful, voice of all the falls of the
Valley, its tones varying from the sharp hiss and rustle of the wind
in the glossy leaves of the live-oak and the soft, sifting, hushing
tones of the pines, to the loudest rush and roar of storm winds and
thunder among the crags of the summit peaks. The low bass, booming,
reverberating tones, heard under favorable circumstances five or six
miles away are formed by the dashing and exploding of heavy masses
mixed with air upon two projecting ledges on the face of the cliff, the
one on which we are standing and another about 200 feet above it. The
torrent of massive comets is continuous at time of high water, while
the explosive, booming notes are wildly intermittent, because, unless
