His favorite plea in such instances was, "If Humboldt and Cuvier, and Linnaeus, and Ehrenberg have made mankind their debtors by scouring the physical cosmos for scientific data, which every living savant devours, assimilates, and reproduces in dynamic, physiologic, or entomologic theories, is it not equally laudable in scholars, orators, and authors--nay, is it not obligatory on them, to subsidize the vast cosmos of literature, to circumnavigate the world of belles-lettres, in search of new hemispheres of thought, and spice islands of illustrations; bringing their rich gleanings to the great public mart, where men barter their intellectual merchandise? Wide as the universe and free as its winds should be the range of human mind." Yielding allegiance to the axiom that "the proper study of mankind is man," and recognizing the fact that history faithfully epitomizes the magnificent triumphs and stupendous failures, the grand capacities and innate frailties of the races, he fostered and stimulated his pupil's fondness for historic investigation; while in impressing upon her memory the chronologic sequence of events he not only grouped into great epochs the principal dramas, over which Clio holds august critical tribunal, but so carefully selected her miscellaneous reading, that poetry, novels, biography, and essays reflected light upon the actors of the particular epoch which she was studying; and thus through the subtle but imperishable links of association of ideas, chained them in her mind. The extensive library at Le Bocage, and the valuable collection of books at the parsonage, challenged research, and, with a boundless ambition, equalled only by her patient, persevering application, Edna devoted herself to the acquisition of knowledge, and astonished and delighted her teacher by the rapidity of her progress and the vigor and originality of her restless intellect. The noble catholicity of spirit that distinguished Mr. Hammond's character encouraged her to discuss freely the ethical and psychological problems that arrested her attention as she grew older, and facilitated her appreciation and acceptance of the great fact, that all bigotry springs from narrow minds and partial knowledge. He taught her that truth, scorning monopolies and deriding patents, lends some valuable element to almost every human system; that ignorance, superstition, and intolerance are the red-handed Huns that ravage society, immolating the pioneers of progress upon the shrine of prejudice--fettering science--blindly bent on divorcing natural and revealed truth, which "God hath joined together" in holy and eternal wedlock; and while they battle a l'outrance with every innovation, lock the wheels of human advancement, turning a deaf ear to the thrilling cry; "Yet I doubt not through the ages one increasing purpose runs, and the thoughts of men are widened with the process of the suns."
