appears of a beautiful pale-yellow color, and the delicate wool fibers
are seen growing up among the strong hairs, like grass among stalks
of corn, every individual fiber being protected about as specially and
effectively as if inclosed in a separate husk. Wild wool is too fine to
stand by itself, the fibers being about as frail and invisible as the
floating threads of spiders, while the hairs against which they
lean stand erect like hazel wands; but, notwithstanding their great
dissimilarity in size and appearance, the wool and hair are forms of
the same thing, modified in just that way and to just that degree that
renders them most perfectly subservient to the well-being of the sheep.
Furthermore, it will be observed that these wild modifications are
entirely distinct from those which are brought chancingly into existence
through the accidents and caprices of culture; the former being
inventions of God for the attainment of definite ends. Like the
modifications of limbs--the fin for swimming, the wing for flying, the
foot for walking--so the fine wool for warmth, the hair for additional
warmth and to protect the wool, and both together for a fabric to wear
well in mountain roughness and wash well in mountain storms.

The effects of human culture upon wild wool are analogous to those
produced upon wild roses. In the one case there is an abnormal
development of petals at the expense of the stamens, in the other an
abnormal development of wool at the expense of the hair. Garden roses
frequently exhibit stamens in which the transmutation to petals may
be observed in various stages of accomplishment, and analogously the
fleeces of tame sheep occasionally contain a few wild hairs that are
undergoing transmutation to wool. Even wild wool presents here and there
a fiber that appears to be in a state of change. In the course of my
examinations of the wild fleeces mentioned above, three fibers were
found that were wool at one end and hair at the other. This, however,
does not necessarily imply imperfection, or any process of change
similar to that caused by human culture. Water lilies contain parts
variously developed into stamens at one end, petals at the other, as
the constant and normal condition. These half wool, half hair fibers may
therefore subserve some fixed requirement essential to the perfection of
the whole, or they may simply be the fine boundary-lines where and exact
balance between the wool and the hair is attaine
