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.

在苏格兰高地偏远内陆地区，甚至有像工这样行业。

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.

一个习惯于做铁匠，如果他唯一或主要业务是做，即使他尽最大努力，也很少在一天内做超过八百或一千个。
