The echoing chamber of his soul was a narrow room , a conning tower , whence were directed his arm and shoulder muscles , his ten nimble fingers , and the swift - moving iron along its steaming path in broad , sweeping strokes , just so many strokes and no more , just so far with each stroke and not a fraction of an inch farther , rushing along interminable sleeves , sides , backs , and tails , and tossing the finished shirts , without rumpling , upon the receiving frame 他靈魂的回音室狹小得如一座錐形的塔,指揮著他的胳膊和肩肌十個靈巧的指頭和熨斗,沿著霧氣騰騰的道路迅跑,做大刀闊斧的揮動。揮動的次數不多不少,而且恰到好處,決不過火,只沿著無窮無盡的兩袖兩腰后背后擺急跑,然后把熨燙完的襯衫甩到承接架上,還不讓它打皺。
