Take a familiar case - that of domestiḍ servan La. Wages in this case are entirely fixed by a bárga le between an individual master and an individual servant. There is no organization o combination on the one side or the other. But it is notorious there is no other occupation in which the rate of wages has risen so much since the world- war as in domestic service, especially among women servants. Why is this? Simply because the supply of servanta has greatly diminished in proportion to the demand for them. There are more masters seeking servants than servants, looking for employment. This is due to many causes: partly to the increasing reluctance of girls to go into domestic service,

partly to the increaseu employment of women in other occupations: During the world-war, when most of the gen went away to fight, women

took their place in offices apa factoriee and shops, and employers discovered thatan cany cases the women could do: the work as well or berter than men, arid would go it for ipus ways Consequently, more
