One model that some one had invented was a steam-engine that walked with iron legs.

有个人发明的模型是个能用铁腿走路的蒸汽机。

For the fugitive out on the marshes with the ironed leg, the mysterious young man, the file, the food, and the dreadful pledge I was under to commit a larceny on those sheltering premises, rose before me in the avenging coals.

对于在沼泽地里用熨烫的腿的逃犯，神秘的年轻人，档案，食物，以及我承诺在那些庇护场所实施盗窃的可怕承诺，在复仇的煤中出现在我面前。
