CHAPTER XXXVI
CARETAKERS AND GOVERNESSES
Because of her versatile adaptability to the management of details, woman, all through the ages, has willingly and happily sacrificed herself upon the altar of service. It is not in the province of this chapter to go into the details of the tribal life of the early hordes and clans that came from the north and from the east to establish civilization in the cities of Rome and Britain—space forbids. In this chapter we wish to hold up a picture to the mother, a picture which may speak volumes to her soul; one which perhaps she may ruthlessly throw away—nevertheless, we propose to exhibit it.
