Character guide

John Muir

major

Also known as John, Mr. Muir

Muir joins Mr. Delaney's flock not as a shepherd but as a watcher of the shepherd, a man free to wander eight or ten miles from camp studying plants, rocks, and scenery. His real tension is between the practical errand — keeping two thousand sheep alive through bears, coyotes, and chaparral — and his truant impulse to abandon duty for a glacier-polished ridge or a view of Half Dome. That divided attention shapes the whole arc: the summer becomes less a job than a conversion, and his early doubts about losing half the flock quietly give way to something closer to joy.

Carlo

supporting

Also known as The noble St. Bernard, St. Bernard Carlo

Carlo arrives as a favor from a hunter friend who fears the plains heat will kill him, and becomes Muir's constant companion on the high trails. He is brave but wary — ears pressed down at a startled bear, watching Muir's face as if expecting a rifle shot — and his baffled concern when Muir shouts and gesticulates on a summit is what brings the naturalist back to his senses. He matters because he gives the solitary summer a second heartbeat, a witness to both the grandeur and the danger.

Bruin

supporting

Also known as neighbor Bruin

Bruin is less a villain than a fellow mountaineer — a brown bear startled from a manzanita thicket who runs off tumbling over brush, evidently judging Muir the dangerous one. The encounter exposes the camp's fragile footing: Carlo's ears flatten, Muir's ecstasy collapses into caution, and the sheep remain somewhere below, vulnerable. Bruin matters because he embodies the summer's central negotiation — how much of this country can be walked through, and how much simply has to be shared.

Mr. Delaney

supporting

Delaney is the practical engine of the expedition: he owns the two thousand and fifty sheep, engages the shepherd, and waves away Muir's confessed ignorance of canyons, rivers, and bears as insignificant. His one requirement is a man he can trust to see the shepherd does his duty. That trust, and his long absences while provisions run low, create the summer's quiet friction — the bread famine, the mutton monotony — and make his rare arrivals feel like verdicts on how the whole venture is going.

Billy

supporting

Also known as Shepherd Billy

Billy tends the sheep while Muir wanders, and his running complaint — that no decent white man can climb these mountains on mutton alone — becomes the expedition's comic refrain. He is practical, aggrieved, and set in his notions of what constitutes real food, and his feud with the bread famine sharpens as Delaney fails to arrive. He matters because he grounds the summer in bodily need: while Muir is rapturing over clouds and glaciers, Billy is reminding everyone that good grub makes good sheep.
