Workmen, on the contrary, when they are liberally paid by the piece, are very apt to overwork themselves, and to ruin their health and constitution in a few years.

相反，工人在按件计酬时很容易过度劳累， 并在几年内毁掉他们的健康和体质。

Something of the same kind happens in many other trades, in which the workmen are paid by the piece; as they generally are in manufactures, and even in country labour, wherever wages are higher than ordinary.

许多其他行业也发生了类似的情况，在这些行业中，工人是按件计酬的。因为他们通常在制造业，甚至在工资高于普通水平的乡村劳动中也是如此。
