"Papce!" said my father. "I think, Mrs. Primmins, you must remain in, to keep the books steady." "Lord love you!" cried Mrs. Primmins, aghast. "The subtraction of such a mass, or moles,--supple and elastic as all flesh is, and fitting into the hard corners of the inert matter,--such a subtraction, Mrs. Primmins, would leave a vacuum which no natural system, certainly no artificial organization, could sustain. There would be a regular dance of atoms, Mrs. Primmins; my books would fly here, there, on the floor, out of the window! "'Corporis officium est quoniam omnia deorsum.' "The business of a body like yours, Mrs. Primmins, is to press all things down, to keep them tight, as you will know one of these days,--that is, if you will do me the favor to read Lucretius, and master that material philosophy of which I may say, without flattery, my dear Mrs. Primmins, that you are a living illustration." These, the first words my father had spoken since we set out from the inn, seemed to assure my mother that she need have no apprehension as to the character of his thoughts, for her brow cleared, and she said, laughing,-- "Only look at poor Primmins, and then at that hill!" "You may subtract Primmins, if you will be answerable for the remnant, Kitty. Only I warn you that it is against all the laws of physics." So saying, he sprang lightly forward, and, taking hold of my arm, paused and looked round, and drew the loud free breath with which we draw native air. "And yet," said my father, after that grateful and affectionate inspiration,--"and yet, it must be owned that a more ugly country one cannot see out of Cambridgeshire." (1) "Nay," said I, "it is bold and large, it has a beauty of its own. Those immense, undulating, uncultivated, treeless tracts have surely their charm of wildness and solitude. And how they suit the character of the ruin! All is feudal there! I understand Roland better now." "I hope to Heaven Cardan will come to no harm!" cried my father; "he is very handsomely bound, and he fitted beautifully just into the fleshiest part of that fidgety Primmins." Blanche, meanwhile, had run far before us, and I followed fast. There were still the remains of that deep trench (surrounding the ruins on three sides, leaving a ragged hill-top at the fourth) which made the favorite fortification of all the Teutonic tribes. A causeway, raised on brick arches, now, however, supplied the place of the drawbridge, and the outer gate was but a mass of picturesque ruin. Entering into the courtyard or bailey, the old castle mound, from which justice had been dispensed, was in full view, rising higher than the broken walls around it, and partially over grown with brambles. And there stood, comparatively whole, the Tower or Keep, and from its portals emerged the veteran owner.
