Quote context

[...]

- Here you are, pilgrim. Sharp enough to scale a fish with.

- Ever get lonesome?

- For what?

- Woman?

- Full-time night woman?

- I never could find no tracks in a woman's heart.

- I packed me a squaw for 10 years, pilgrim. Cheyenne, she was. And the meanest bitch that ever balled for beads! I lodgepoled her at Dead Wolf Creek and traded her for a Hawkin gun!

- Don't get me wrong, I love the women, I surely do!

- But I swear a woman's breast is the hardest rock the Almighty ever made on Earth and I can find no sign on it.

- Now these coals here will simmer until sunrise. You better go do likewise.

- Didn't put enough dirt down. Saw it right off.

- You track well, pilgrim. Kind of like it, don't you?

- Maybe. Figures. A human man likes tracking and killing. An Injun, he figures it's natural.

- Wind's right. But he'll just run, soon as we step out of these trees.
