tracted, and is inefficient for some time after changing to a new thing. Even in this case, habit, I believe, much more than nature, is the cause of the difference. The occupations of nine out of every ten men are special, those of nine out of every ten women general, embracing a multitude of details, each of which requires very little time. Women are in the constant practice of passing quickly from one manual, and still more from one mental operation to another, which therefore rarely costs them either effort or loss of time, while a man's occupation generally consists in working steadily for a long time at one thing, or one very limited class of things. But the situations are sometimes reversed, and with them the characters. Women are not found less efficient than men for the uniformity of factory work, or they would not so generally be employed for it; and a man who has cultivated the habit of turning his hand to many things, far from being the slothful and lazy person described by Adam Smith, is usually remarkably lively and active. It is true, however, that change of occupation may be too frequent even for the most versatile. Incessant variety is even more fatiguing than perpetual sameness.
The third advantage attributed by Adam Smith to the division of labour, is, to a certain extent, real. Inventions tending to save labour in a particular operation, are more likely to occur to any one in proportion as his thoughts are intensely directed to that occupation, and continually employed upon it. A person is not so likely to make practical improvements in one department of things, whose attention is very much diverted to others. But, in this, much more depends on general intelligence and habitual activity of mind, than on exclusiveness of occupation; and if that exclusiveness is carried to a degree unfavourable to the cultivation of intelligence, there will be more lost in this kind of advantage, than gained. We may add, that whatever may be the cause of making inventions, when they are once made, the
