But avarice could not forever blind men's eyes to scenes of sorrow, nor stop their ears to sounds of woe. When the horrors of the slave-market and the infamies of the cotton-field filled all the land with shame reformers arose, declaring that the attempt to compress and confine liberty would end in explosion. In that hour Northern men made tentative overtures looking to the purchase of all slaves. But slavery, Delilah-like, made the southern leaders drunk with the cup of sorcery. They scorned the proposition. In the light of subsequent events we see that in saving her institution the South lost it, and with it her wealth, while in losing her slaves the North gained her wealth. Under free labor the North doubled its population, its manufactories, its riches and waxed mighty. Under slave-labor the South dwindled in wealth and became only the empty shell of a state. The spark fired at Fort Sumter kindled a conflagration that swept through the sunny South like a devastating fire and revealed its inner poverty. When four years had passed by the farmhouses and factories were ruins, the village was a heap, the town a desolation. Graveyards were as populous as cities, each village had its company of cripples, the cry of the orphan and the widow filled all the land. When Charles Darwin returned from his voyage around the world, he sent a generous contribution to the London Missionary Society. The great scientist had discovered that in lessening her wealth through missions England had saved her treasure through commerce. Traveling in foreign lands, Darwin noticed that the Christian teachers in schools that now touch 3,000,000 of young men and women in India, were really commercial agents for England's trade. In awakening the minds of the darkened millions the teacher had created a demand for books, newspapers and printing-presses. In awakening the sense of self-respect the teacher had created a demand for English clothing and the product of English looms. Also the influence of each home, with its comforts and conveniences, created a demand for English tools and improvements of labor. Summing up his observation, Lord Havelock said that each thousand dollars England had spent upon her missions had brought a return of a hundred thousand dollars through her commerce. Hitherto the interior of China has been closed to English merchants. To that dark land, therefore, England has sent 200 teachers whose homes are centers of light and inspiration. When two-score years have passed English fleets will be taxed to the utmost to carry to China, as now to India, her fabrics of cotton and wool, her presses, looms, sewing-machines, her pictures, her libraries. In giving of her wealth to found these destitute schools England will save it a hundred-fold and find new markets among 300,000,000 people.
