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

谁也说不准一旦大火起来会到哪里为止。

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

看去暖和了一些，但依旧没有燎原之火。

The prairie fire was roaring now, roaring louder and louder in the screaming wind.

原的大火正熊熊燃，啸的狂风中越越烈。

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.

他们之所以被称为黑腿，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。
