And there's no telling where a prairie fire will stop, once it gets started.

说不准一旦大火烧起来会烧到哪里为止。

She looked a little warmer, but still no prairie fire.

她看上去暖和了一些，但依旧没有燎原之火。

原上的大火正在熊熊燃烧，在呼啸的狂风中越烧越烈。

They're called the Black Legs because the other side tried to make them retreat by starting a prairie fire so the fire would wash over them and move them back.

他们之所为黑腿，是因为对方试图通过燎原之火让他们撤退，这样大火就会冲刷他们并将他们赶回去。
