a look of supreme contempt

The page glanced on her a look of supreme contempt, but vouchsafed no other answer. His mistress, who began to feel herself seriously offended, and yet sorry for the youth’s folly, took up the same tone.
Indeed, Roland, you forget yourself so strangely, said she, that you will tempt me to take serious measures to lower you in your own opinion by reducing you to your proper station in society.
And that, added Lilias, would be best done by turning him out the same beggar’s brat that your ladyship took him in.
Lilias speaks too rudely, continued the Lady, but she has spoken the truth, young man; nor do I think I ought to spare that pride which hath so completely turned your head. You have been tricked up with fine garments, and treated like the son of a gentleman, until you have forgot the fountain of your churlish blood.
Craving your pardon, most honourable madam, Lilias hath not spoken truth, nor does your ladyship know aught of my descent, which should entitle you to treat it with such decided scorn. I am no beggar’s brat — my grandmother begged from no one, here nor elsewhere — she would have perished sooner on the bare moor. We were harried out and driven from our home — a chance which has happed elsewhere, and to others. Avenel Castle, with its lake and its towers, was not at all times able to protect its inhabitants from want and desolation.
Hear but his assurance! said Lilias, he upbraids my Lady with the distresses of her family!
It had indeed been a theme more gratefully spared, said the Lady, affected nevertheless with the allusion.
It was necessary, madam, for my vindication, said the page, or I had not even hinted at a word that might give you pain. But believe, honoured Lady, I am of no churl’s blood. My proper descent I know not; but my only relation has said, and my heart has echoed it back and attested the truth, that I am sprung of gentle blood, and deserve gentle usage.
And upon an assurance so vague as this, said the Lady, do you propose to expect all the regard, all the privileges, befitting high rank and distinguished birth, and become a contender for concessions which are only due to the noble? Go to, sir, know yourself, or the master of the household shall make you know you are liable to the scourge as a malapert boy. You have tasted too little the discipline fit for your age and station.
The master of the household shall taste of my dagger, ere I taste of his discipline, said the page, giving way to his restrained passion. Lady, I have been too long the vassal of a pantoufle, and the slave of a silver whistle. You must henceforth find some other to answer your call; and let him be of birth and spirit mean enough to brook the scorn of your menials, and to call a church vassal his master.
I have deserved this insult, said the Lady, colouring deeply, for so long enduring and fostering your petulance. Begone, sir. Leave this castle to-night — I will send you the means of subsistence till you find some honest mode of support, though I fear your imaginary grandeur will be above all others, save those of rapine and violence. Begone, sir, and see my face no more.
