Employ Fabre's method if you wish to learn by yourself, or to evoke in your children a love of science, and, according to the phrase of the gentle Jean-Jacques, to help them "to buy at the best possible of prices." Give them as sole guides these exquisite manuals, which touch upon everything, initiating them into everything, and bringing within the reach of all, for their instruction or amusement, the heavens and the earth, the planets and their moons, the mechanism of the great natural forces and the laws which govern them, life and its materials, agriculture and its applications. For more than a quarter of a century these catechisms of science, models of lucidity and good sense, effected the education of generations of Frenchmen. Abridgments of all knowledge, veritable codes of rural wisdom, these perfect breviaries have never been surpassed. It was after reading these little books, it is said, that Duruy conceived the idea of confiding to this admirable teacher the education of the Imperial heir; and it is very probable that this was, in reality, the secret motive which would explain why he had so expressly summoned Fabre to Paris. What an ideal tutor he had thought of, and how proud might others have been of such a choice! But the man was too zealous of his independence, too difficult to tame, to bear with the environment of a court, and God knows whether he was made for such refulgence! We need not be surprised that Fabre never heard of it; it must have sufficed the minister to speak with him for a few minutes to realize that the most tempting offers and all the powers of seduction would never overcome his insurmountable dislike of life in a capital, nor prevail against his inborn, passionate, exclusive love of the open. For these volumes Fabre was at first rather wretchedly paid; at all events, until public education had definitely received a fresh impulse; and for a long time his life at Orange was literally a hand-to-mouth existence. As soon as he was able to realize a few advances, he had nothing so much at heart as the repayment of Mill, and he hastened to call on the philosopher; all the more filled with gratitude for his generosity in that the loan, although of the comparatively large amount of three thousand francs, was made without security, practically from hand to hand, with no other warranty than his probity. For this reason this episode was always engraven on his memory. Thirty years later he would relate the affair even to the most insignificant details. How many times has he not reminded me of the transaction, insisting that I should make a note of it, so anxious was he that this incident in his career should not be lost in oblivion! How often has he not recalled the infinite delicacy of Mill, and his excessive scrupulousness, which went so far that he wished to give a written acknowledgment of the repayment of the debt, of which there was no record whatever save in the conscience of the debtor!
