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

谁也说不准一旦大起到哪里为止。

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

草原上的大正在熊熊燃，在呼啸的风中越越烈。

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。

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让他们撤退，这样大就冲刷他们并将他们赶回去。
