Excerpt from Steep Trails, by John Muir

As already stated, the clothing of our wild sheep is composed of fine
wool and coarse hair. The hairs are from about two to four inches long,
mostly of a dull bluish-gray color, though varying somewhat with the
seasons. In general characteristics they are closely related to the
hairs of the deer and antelope, being light, spongy, and elastic, with
a highly polished surface, and though somewhat ridged and spiraled,
like wool, they do not manifest the slightest tendency to felt or
become taggy. A hair two and a half inches long, which is perhaps near
the average length, will stretch about one fourth of an inch before
breaking. The diameter decreases rapidly both at the top and bottom,
but is maintained throughout the greater portion of the length with a
fair degree of regularity. The slender tapering point in which the
hairs terminate is nearly black: but, owing to its fineness as compared
with the main trunk, the quantity of blackness is not sufficient to
affect greatly the general color. The number of hairs growing upon a
square inch is about ten thousand; the number of wool fibers is about
twenty-five thousand, or two and a half times that of the hairs. The
wool fibers are white and glossy, and beautifully spired into ringlets.
The average length of the staple is about an inch and a half. A fiber
of this length, when growing undisturbed down among the hairs, measures
about an inch; hence the degree of curliness may easily be inferred. I
regret exceedingly that my instruments do not enable me to measure the
diameter of the fibers, in order that their degrees of fineness might
be definitely compared with each other and with the finest of the
domestic breeds; but that the three wild fleeces under consideration
are considerably finer than the average grades of Merino shipped from
San Francisco is, I think, unquestionable.

When the fleece is parted and looked into with a good lens, the skin
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 attained.

Explanation

**Detailed Explanation of the Excerpt from Steep Trails by John Muir**

Context of the Source

John Muir (1838–1914) was a Scottish-American naturalist, conservationist, and writer, often called the "Father of National Parks" for his role in preserving wilderness areas like Yosemite. Steep Trails (1918) is a posthumous collection of his essays and journal entries, documenting his observations of nature, particularly in the American West. This excerpt focuses on the wild sheep (likely the bighorn sheep, Ovis canadensis), examining their wool and hair in meticulous scientific and aesthetic detail.

Muir’s writing blends natural history, ecological philosophy, and reverence for the divine in nature. His work often reflects Transcendentalist influences (like Emerson and Thoreau), emphasizing the spiritual and functional perfection of the natural world.

Themes in the Excerpt

Divine Design in Nature
- Muir presents the wild sheep’s fleece as a perfect adaptation, crafted by a higher intelligence ("inventions of God for the attainment of definite ends").
- He contrasts this with human interference (domestication, selective breeding), which he sees as artificial and often inferior.
- The wool and hair are not random but purposefully modified for survival—warmth, protection, and durability.
Interconnectedness of Form and Function
- The fleece is a harmonious system: wool for insulation, hair for structure and weather resistance.
- Muir compares it to limbs adapted for specific purposes (fins for swimming, wings for flying), reinforcing his belief in nature’s teleological design (everything has a purpose).
Human vs. Wild Modifications
- Domesticated sheep (like Merinos) have excessive wool at the expense of hair, just as garden roses have excessive petals at the expense of stamens.
- Muir critiques human manipulation of nature, suggesting it leads to imbalance (e.g., weak, overly woolly sheep vs. the resilient wild sheep).
- The rare hybrid fibers (half-wool, half-hair) in wild sheep are not flaws but possible transitional forms serving a deeper biological balance.
Scientific Observation as Worship
- Muir’s detailed measurements (hair length, stretch capacity, fiber count) reflect his reverence for nature’s precision.
- His aesthetic appreciation ("beautiful pale-yellow skin," "glossy, spired ringlets") merges science with poetry, treating nature as both a subject of study and a sacred text.

Literary Devices & Stylistic Features

Scientific Precision & Imagery
- Muir employs quantitative descriptions ("ten thousand hairs per square inch," "stretch about one fourth of an inch") to ground his observations in empirical reality.
- Metaphors and similes enhance visualization:
  - Wool fibers like "floating threads of spiders"
  - Hairs standing "like hazel wands"
  - Wool growing "like grass among stalks of corn"
- Tactile and visual imagery ("highly polished surface," "beautifully spired into ringlets") immerses the reader in the texture of the fleece.
Contrast & Juxtaposition
- Wild vs. Domestic: Wild sheep’s fleece is balanced and functional; domestic wool is excessive and weak.
- Divine vs. Human Design: Nature’s modifications are purposeful; human alterations are capricious ("accidents and caprices of culture").
- Structure vs. Frailty: The strong hairs support the delicate wool, illustrating interdependence.
Personification & Teleology
- Nature is active and intentional: fibers are "protected as if inclosed in a separate husk," modifications "subserve some fixed requirement."
- Muir attributes agency to natural processes, framing them as divine inventions rather than random evolution (though his views predate modern evolutionary theory).
Extended Analogies
- Roses and Sheep: Both are altered by human cultivation—roses lose stamens for petals, sheep lose hair for wool.
- Water Lilies: Some plants naturally have dual-function parts (stamens/petals), suggesting that the hybrid wool-hair fibers in sheep may also be naturally purposeful.
Tone: Reverence & Wonder
- Muir’s tone is awestruck yet analytical, blending scientific detachment with poetic admiration.
- Phrases like "I regret exceedingly that my instruments do not enable me" show his humility before nature’s complexity.

Significance of the Passage

Ecological Philosophy
- Muir’s holistic view of nature—where every detail has a purpose—challenges anthropocentric (human-centered) perspectives.
- His critique of domestication foreshadows modern concerns about genetic modification and industrial agriculture.
Bridge Between Science and Spirituality
- Muir does not separate fact from faith; his measurements are acts of devotion.
- This aligns with Transcendentalist and Romantic traditions, where nature is both a laboratory and a temple.
Influence on Conservation Ethics
- By emphasizing the perfection of wild systems, Muir implicitly argues for preserving nature in its original state.
- His work laid groundwork for wilderness protection movements, including the Sierra Club (which he co-founded).
Literary Legacy
- Muir’s descriptive prose influenced nature writing (e.g., Annie Dillard, Barry Lopez).
- His fusion of science and lyricism remains a model for ecological literature.

Line-by-Line Analysis of Key Sections

"The hairs are from about two to four inches long, mostly of a dull bluish-gray color..."
- Purpose: Establishes the baseline characteristics of the sheep’s outer coat.
- Significance: The color and texture are adapted for camouflage and insulation in mountainous terrain.
"A hair two and a half inches long... will stretch about one fourth of an inch before breaking."
- Scientific rigor: Muir tests the elasticity, showing how the hair resists wear in rugged environments.
- Implication: The fleece is engineered for durability, unlike domestic wool which may be softer but weaker.
"The wool fibers are white and glossy, and beautifully spired into ringlets."
- Aesthetic appreciation: Muir marvels at beauty, not just function.
- Contrast: The curliness traps air for warmth, while the hairs provide structure.
"Wild wool is too fine to stand by itself... the wool and hair are forms of the same thing..."
- Interdependence: The two components complement each other, a recurring theme in Muir’s view of ecosystems.
- Philosophical point: Nature’s designs are unified and efficient, unlike human modifications which often sacrifice balance.
"Like the modifications of limbs—the fin for swimming, the wing for flying..."
- Teleological argument: Each feature has a clear purpose, reinforcing Muir’s belief in intelligent design in nature.
- Connection to Darwinism: While Muir doesn’t reject adaptation, he prefers a divine explanation over random mutation.
"The effects of human culture upon wild wool are analogous to those produced upon wild roses."
- Critique of domestication: Humans distort nature’s balance for aesthetic or economic gains.
- Example: Garden roses are pretty but sterile; domestic sheep are woolly but frail.
"These half wool, half hair fibers may therefore subserve some fixed requirement..."
- Open-mindedness: Muir doesn’t dismiss anomalies but sees them as potentially purposeful.
- Scientific humility: He acknowledges limits to his understanding, a trait of true naturalists.

Conclusion: Why This Passage Matters

This excerpt exemplifies Muir’s unique blend of science, art, and spirituality. He doesn’t just describe the wild sheep’s fleece—he celebrates it as a masterpiece of natural engineering, while warning against human meddling. His writing is:

Observational (detailed measurements),
Philosophical (reflecting on design and purpose),
Poetic (rich in metaphor and wonder).

Muir’s perspective remains relevant today, as debates continue over wilderness preservation, genetic modification, and humanity’s role in nature. His work reminds us that true understanding of nature requires both rigor and reverence.

Solutions and Explanations

1) Correct answer: D

Why D is most correct: Muir explicitly frames the wild sheep’s fleece as an "invention of God for the attainment of definite ends," aligning with a teleological (purpose-driven) view of nature. His comparisons to limbs adapted for specific functions (e.g., fins for swimming) further reinforce the idea that these traits are intentionally designed for optimal survival. The passage’s reverential language ("perfectly subservient to the well-being of the sheep") leaves no doubt that Muir sees these adaptations as purposeful, not random.
