“You cannot then confide in the nature of my wishes?”

“Grant me till to-morrow,” said Dorothea, beseechingly.

“Till to-morrow then,” said Mr. Casaubon.

Soon she could hear that he was sleeping, but there was no more sleep for her.  While she constrained herself to lie still lest she should disturb him, her mind was carrying on a conflict in which imagination ranged its forces first on one side and then on the other.  She had no presentiment that the power which her husband wished to establish over her future action had relation to anything else than his work.  But it was clear enough to her that he would expect her to devote herself to sifting those mixed heaps of material, which were to be the doubtful illustration of principles still more doubtful.  The poor child had become altogether unbelieving as to the trustworthiness of that Key which had made the ambition and the labor of her husband’s life.  It was not wonderful that, in spite of her small instruction, her judgment in this matter was truer than his:  for she looked with unbiassed comparison and healthy sense at probabilities on which he had risked all his egoism.  And now she pictured to herself the days, and months, and years which she must spend in sorting what might be called shattered mummies, and fragments of a tradition which was itself a mosaic wrought from crushed ruins—­sorting them as food for a theory which was already withered in the birth like an elfin child.  Doubtless a vigorous error vigorously pursued has kept the embryos of truth a-breathing:  the quest of gold being at the same time a questioning of substances, the body of chemistry is prepared for its soul, and Lavoisier is born.  But Mr. Casaubon’s theory of the elements which made the seed of all tradition was not likely to bruise itself unawares against discoveries:  it floated among flexible conjectures no more solid than those etymologies which seemed strong because of likeness in sound until it was shown that likeness in sound made them impossible:  it was a method of interpretation which was not tested by the necessity of forming anything which had sharper collisions than an elaborate notion of Gog and Magog:  it was as free from interruption as a plan for threading the stars together.  And Dorothea had so often had to check her weariness and impatience over this questionable riddle-guessing, as it revealed itself to her instead of the fellowship in high knowledge which was to make life worthier!  She could understand well enough now why her husband had come to cling to her, as possibly the only hope left that his labors would ever take a shape in which they could be given to the world.  At first it had seemed that he wished to keep even her aloof from any close knowledge of what he was doing; but gradually the terrible stringency of human need—­the prospect of a too speedy death—­
