Labours is the second of the pair of processes skills (the first being Farming) associated with the production of the various commodities of life. The skill, like Farming, contains around thirty abilities dealing with a wide range of pursuits; mining for ores, panning for gold, spinning cotton, blowing glass, dye-making, and so on. Like Farming, Labours cannot be advanced by simply learning lessons or teaching lessons - it must be practiced for advancement. You will gain the benefit of your practise at regular intervals providing you have spent sufficient time performing some labour or other.
