" That a smith condemned for life to make the heads of nails would lose all interest in his work, that he would be entirely at the mercy of his employer with his limited handicraft, that he would be out of work four months out of twelve, and that his wages would fall very low down, when it would be easy to replace him by an apprentice, Smith did not think of all this when he exclaimed - 'Long live the division of labour. This is the real gold-mine that will enrich the nation!' And all joined him in this cry. "
