From the beginning, she had sat looking at him fixedly. As he now leaned back in his chair, and bent his deep-set eyes upon her in his turn, perhaps he might have seen one wavering moment in her, when she was impelled to throw herself upon his breast, and give him the pent-up confidences of her heart. But, to see it, he must have overleaped at a bound the artificial barriers he had for many years been erecting, between himself and all those subtle essences of humanity which will elude the utmost cunning of algebra until the last trumpet ever to be sounded shall blow even algebra to wreck. The barriers were too many and too high for such a leap. With his unbending, utilitarian, matter-of-fact face, he hardened her again; and the moment shot away into the plumbless depths of the past, to mingle with all the lost opportunities that are drowned there. Removing her eyes from him, she sat so long looking silently towards the town, that he said, at length: ‘Are you consulting the chimneys of the Coketown works, Louisa?’ ‘There seems to be nothing there but languid and monotonous smoke. Yet when the night comes, Fire bursts out, father!’ she answered, turning quickly. ‘Of course I know that, Louisa. I do not see the application of the remark.’ To do him justice he did not, at all. She passed it away with a slight motion of her hand, and concentrating her attention upon him again, said, ‘Father, I have often thought that life is very short.’—This was so distinctly one of his subjects that he interposed. ‘It is short, no doubt, my dear. Still, the average duration of human life is proved to have increased of late years. The calculations of various life assurance and annuity offices, among other figures which cannot go wrong, have established the fact.’ ‘I speak of my own life, father.’ ‘O indeed? Still,’ said Mr. Gradgrind, ‘I need not point out to you, Louisa, that it is governed by the laws which govern lives in the aggregate.’ ‘While it lasts, I would wish to do the little I can, and the little I am fit for. What does it matter?’ Mr. Gradgrind seemed rather at a loss to understand the last four words; replying, ‘How, matter? What matter, my dear?’ ‘Mr. Bounderby,’ she went on in a steady, straight way, without regarding this, ‘asks me to marry him. The question I have to ask myself is, shall I marry him? That is so, father, is it not? You have told me so, father. Have you not?’ ‘Certainly, my dear.’ ‘Let it be so. Since Mr. Bounderby likes to take me thus, I am satisfied to accept his proposal. Tell him, father, as soon as you please, that this was my answer. Repeat it, word for word, if you can, because I should wish him to know what I said.’ ‘It is quite right, my dear,’ retorted her father approvingly, ‘to be exact. I will observe your very proper request. Have you any wish in reference to the period of your marriage, my child?’ ‘None, father. What does it matter!’
