Trusting to this well-ascertained state of things, he had not hesitated to declare his love for Miss Thorne before his sister Augusta.  But his sister Augusta had now, as it were, been received into the upper house; having duly profited by the lessons of her great instructress, she was now admitted to sit in conclave with the higher powers:  her sympathies, of course, became changed, and her confidence was removed from the young and giddy and given to the ancient and discreet.  She was as a schoolboy, who, having finished his schooling, and being fairly forced by necessity into the stern bread-earning world, undertakes the new duties of tutoring.  Yesterday he was taught, and fought, of course, against the schoolmaster; to-day he teaches, and fights as keenly for him.  So it was with Augusta Gresham, when, with careful brow, she whispered to her mother that there was something wrong between Frank and Mary Thorne.

‘Stop it at once, Arabella:  stop it at once,’ the countess had said; ’that, indeed, will be the ruin.  If he does not marry money, he is lost.  Good heavens! the doctor’s niece!  A girl that nobody knows where she comes from!’

‘He’s going with you to-morrow, you know,’ said the anxious mother.

’Yes; and that is so far well:  if he will be led by me, the evil may be remedied before he returns; but it is very, very hard to lead young men.  Arabella, you must forbid that girl to come to Greshamsbury again on any pretext whatever.  The evil must be stopped at once.’

‘But she is here so much as a matter of course.’

’Then she must be here as a matter of course no more:  there has been folly, very great folly, in having her here.  Of course she would turn out to be a designing creature with such temptation before her; with such a prize within her reach, how could she help it?’

‘I must say, aunt, she answered him very properly,’ said Augusta.

‘Nonsense,’ said the countess; ’before you of course she did.  Arabella, the matter must not be left to the girl’s propriety.  I never knew the propriety of a girl of that sort to be fit to be depended on yet.  If you wish to save the whole family from ruin, you must take steps to keep her away from Greshamsbury now at once.  Now is the time; now that Frank is going away.  Where so much, so very much depends on a young man’s marrying money, not one day ought to be lost.’

Instigated in this manner, Lady Arabella resolved to open her mind to the doctor, and to make it intelligible to him, that under present circumstances, Mary’s visits at Greshamsbury had better be discontinued.  She would have given much, however, to have escaped this business.  She had in her time tried one or two falls with the doctor, and she was conscious that she had never yet got the better of him:  and then she was in a slight degree afraid of Mary herself.  She had a presentiment that it would not be so easy to banish Mary from Greshamsbury:  she was not sure that that young lady would not boldly assert her right to her place in the school-room; appeal loudly to the squire, and perhaps, declare her determination of marrying the heir, out before them all.  The squire would be sure to uphold her in that, or in anything else.
