This difference is most striking in the mechanic arts, but it is clearly visible also in husbandry. Not the most fertile soil, not mines of silver and gold, can make a nation rich, without intelligence. Who ever had a more fertile soil than the Egyptians? Who have handled more silver and gold than the Spaniards? The universal cultivation of the mind and heart is the only true source of opulence;--the cultivation of the mind, by which to lay hold on the treasures of nature; the cultivation of the heart, by which to devote those treasures to beneficent uses. Where this cultivation exists, no matter how barren the soil or ungenial the clime, there comfort and competence will abound; for it is the intellectual and moral condition of the cultivator that impoverishes the soil or makes it teem with abundance. He who disobeys the law of God in regard to the culture of the intellectual and spiritual nature, may live in the valley of the Nile, but he can rear only the “lean kine” of Pharaoh; but he who obeys the highest law may dwell in the cold and inhospitable regions of Scotland or of New England, and “well-formed and fat-fleshed kine” shall feed on all his meadows. If Pharaoh will be a taskmaster, and will not let the bondmen go free, the corn in his field shall be the “seven thin ears blasted by the east wind;” but if he will obey the commandments of the Lord, then behold there shall be “seven ears of corn upon one stalk, all rank and good.” Sir, the sweat of a slave poisons the soil upon which it falls; his breath is mildew to every green thing; his tear withers the verdure it drops upon.
