Bear in mind both these last great proverbs; and combine them in your mind. Remember that while England is, and ever will be, behindhand in metaphysical and scholastic science, she is the nation which above all others has conquered nature by obeying her; that as it pleased God that the author of that proverb, the father of inductive science, Bacon Lord Verulam, should have been an Englishman, so it has pleased Him that we, Lord Bacon's countrymen, should improve that precious heirloom of science, inventing, producing, exporting, importing, till it seems as if the whole human race, and every land from the equator to the pole must henceforth bear the indelible impress and sign manual of English science. And bear in mind, as I said just now, that this study of natural history is the grammar of that very physical science which has enabled England thus to replenish the earth and subdue it. Do you not see, then, that by following these studies you are walking in the very path to which England owes her wealth; that you are training in yourselves that habit of mind which God has approved as the one which He has ordained for Englishmen, and are doing what in you lies toward carrying out, in after life, the glorious work which God seems to have laid on the English race, to replenish the earth and subdue it? One word more, and I have done. Unless you are already tired of hearing me, I would suggest a few practical hints before we part. The best way of learning these matters is by classes, in which men may combine and interchange their thoughts and observations. The greatest savants find this; and have their Microscopic Society, Linnaean, Royal, Geological Societies, British Associations, and what not, in which all may know what each has done, and each share in the learning of all; for as iron sharpeneth iron, so a man sharpens the face of his friend. I have nothing to say against debating societies: perhaps it was my own fault that whenever I belonged to one as a young man, I found them inclined to make me conceited, dictatorial, hasty in my judgments, trying to state a case before I had investigated it, to teach others before I had taught myself, to make a fine speech, not to find out the truth; till in, I think, a wise moment for me, I vowed at twenty never to set foot in one again, and kept my vow. Be that as it may, I wish that side by side with the debating society, I could see young men joining in natural history societies; going out in company on pleasant evenings to search together after the hidden treasures of God's world, and read the great green book which lies open alike to peasant and to peer; and then meeting, say once a week, to debate, not of opinions but of facts; to show each what they had found, to classify and explain, to learn and to wonder together. In such a class many appliances would be possible. A microscope, for instance, or chemical apparatus, might belong to the society, which
