Let the people be employed (in forced labor) at seasonable times. This is an ancient and excellent rule. Let them be employed, therefore, in the winter months, when they are at leisure. But from Spring to Autumn, when they are engaged in agriculture or with the mulberry trees, the people should not be so employed. For if they do not attend to agriculture, what will they have to eat? if they do not attend to the mulberry trees, what will they do for clothing?
