It is impossible there should be such a trade as even that of a nailer in the remote and inland parts of the highlands of Scotland.

格兰高地的偏远内陆地区，甚至可能有像钉工这样的行业。

A smith who has been accustomed to make nails, but whose sole or principal business has not been that of a nailer, can seldom, with his utmost diligence, make more than eight hundred or a thousand nails in a day.

个习惯于钉子的铁匠，如果他的唯或主要业务钉子的，即使他尽最大的努力，也很少能天内超过八百或千个钉子。
