Here is an xcerption from the published screenplay detailing the potato-peeling scene:
Jack peels potatoes for dinner. Ennis has only his jeans and boots on, no shirt, before a large basin of hot water, shaves.
Ennis: "Shot a coyote, big son of a bitch, balls on him size a apples. Looked like he could eat a camel. (sloshes his face) You want some of this hot water?"
Jack (grins, shakes his head): "It's all yours."
Ennis pulls off his boots, then his socks. Pulls off his jeans -- no underwear. Slops the washcloth under his arms, between his legs. Jack fixes dinner, a cigarette dangling from his mouth. Impassive.
