To begin with, it is very natural that she should have suffered in her maternal dignity, as well as in her conscience as a Christian, by having to put up with the company of a stranger who was her son's mistress. However large we may suppose the house where the African tribe dwelt, a certain clashing between the guests was unavoidable. Generally, disputes as to who shall direct the domestic arrangements divide mother-in-law and daughter-in-law who live under one roof. What could be Monnica's feelings towards a woman who was not even a daughter-in-law and was regarded by her as an intruder? She did not consider it worth while to make any attempt at regulating the entanglement of her son by marrying them: this person was of far too low a class. It is all very well to be a saint, but one does not forget that one is the widow of a man of curial rank, and that a middle-class family with self-respect does not lower itself by admitting the first-comer into its ranks by marriage. But these were secondary considerations in her eyes. The only one which could have really preyed on her mind is that this woman delayed Augustin's conversion. On account of her, as Monnica saw plainly, he put off his baptism indefinitely. She was the chain of sin, the unclean past under whose weight he stifled. He must be freed from her as soon as possible. Convinced therefore that such was her bounden duty, she worked continually to make him break off. By way of putting him in some sort face to face with a deed impossible to undo, she searched to find him a wife, with the fine eagerness that mothers usually put into this kind of hunt. She discovered a girl who filled, as they say, all the requirements, and who realized all the hopes of Augustin. She had a fortune considerable enough not to be a burthen on her husband. Her money, added to the professor's salary, would allow the pair to live in ease and comfort. So they were betrothed. In the uncertainty about all things which was Augustin's state just then, he allowed his mother to work at this marriage. No doubt he approved, and like a good official he thought it was time for him to settle down.
