progress. Sink to the lowest mine, or fathom the ocean's depth, or climb the loftiest mountains, or career through the heavens on silken wings, and it is there also. On—on—on; nearer—nearer—still nearer it moves forever and forever, with accelerated speed, toward the infinite eternal. Such are the triumphs of knowledge; and he who diffuses it among our race, or discovers and disseminates new truths, advances man nearer to his Creator. He exalts the whole race; he elevates it in the scale of being, and raises it into higher and still higher spheres.

It is science that marks the speed of sound and light and lightning, calculates the eclipses, catalogues the stars, maps the heavens, and follows, for centuries of the past and the future, the comet's course. It explores the animal, vegetable, and mineral kingdoms. With geology, it notes the earthquake, upheaval of mountains, and, with mineralogy, the laws of crystallization. With chemistry, it analyzes, decomposes, and compounds the elements. If, like Canute, it cannot arrest the tidal wave, it is subjecting it to laws and formulas. Taking the sunbeam for its pencil, it pictures man's own image, and the scenery of the earth and the heavens. Has science any limits or horizon? Can it ever penetrate the soul of man, and reveal the mystery of his existence and destiny? It is certainly exploring the facts of sociology, arranging and generalizing them, and deducing laws. It regards man in his social relations, in families, tribes, and governments, savage, semi-barbarous, and civilized; beginning with the most simple, advancing to the chief, the patriarch, the king, the feudal military, the regal aristocratic, the pure democracy by popular assemblages, as in Athens and the school towns of Massachusetts, rising higher to the central representative, and to the highest, although necessarily more complex, the federal constitutional representative, carrying out the organic division, and the subdivision of legislative and administrative action—regarding the state, the national, and international policy, and, in the lapse of centuries, the confederacy, fusion, and unification of nations. The constitution of empires, with the legislative, judicial, and executive functions, furnish some of the elements of sociology. But we must take the history of man, past, present, and future, note and arrange and generalize the facts, and thence deduce laws and formulas. Sociology is not a mere accidental and disconnected series of facts, but it has laws, although far less known than those appertaining to the physical sciences. The work is commenced, and progresses here and in Europe. But, at this moment, at least in administrative action, Massachusetts is ahead of all the world in the science of sociology.

Man, elevated by knowledge in the scale of being, controls the forces of nature with greater power and grander results, and accumulates wealth more rapidly. The educated free labor of Massachusetts, we have seen, triples the products of toil, per capita, as compared with Maryland, and quintuples them (as the census shows) compared with South Carolina. One day's labor of a man in Massachusetts is equal to three in Maryland, and five in South Carolina. So, if we take our savage tribes, with their huts and tents, their rude agriculture, their furs, their few and simple household manufactures, their hunting and fishing, the average product of their annual labor, at four cents a day each, would be $14.60 a year, or more than a fourth of that of South Carolina (56.91). So that Massachusetts, in material progress, is farther in advance of South Carolina than that State is of the savage Indians. Thus, we have the successive steps and gradations of man: Massachusetts, with free labor and free schools, having reached the highest point of civilization; South Carolina, with slavery and ignorance (except the few), in a semi-barbarous stage; and the lowest savage condition, called barbarous, but nearer to South Carolina than that State to Massachusetts.

Slavery, then, the census proves, is hostile to the progress of wealth and population, to science, literature, and education, to schools, colleges, and universities, to books and libraries, to churches and religion, to the press, and therefore to free government; hostile to the poor, keeping them in want and ignorance; hostile to labor, reducing it to servitude, and decreasing two thirds the value of its products; hostile to morals, repudiating among slaves the marital and parental condition, classifying them by law as chattels, darkening the immortal soul, and making it a crime to teach millions of human beings to read or write. And shall labor and education, literature and science, religion and the press, sustain an institution which is their deadly foe?

But slavery is the enemy of free government. It has commenced and now wages an unholy war against this Union, and thus assails the liberty of our country and of mankind. It has framed a government based on the eternity of chattel slavery, and demands in its name to rule the larger portion of the Union. It seeks to sever the lakes from the gulf, and the mighty Mississippi and its vast arterial tributary system. It asks to be let alone in the commission of all these heaven-daring crimes. In the name of my bleeding country, of the millions whom it has doomed to death, or wounds, or chains, or misery; in the name of the widows and orphans it has made, whose bitter tears and agonizing sighs now fill our land with sorrow; in the name of the free and blessed government it seeks to overthrow, and the glorious Union it strives to dissolve; in the name of God and man, of religion and liberty, the world arraigns the criminal at the bar of justice. Now is the day of trial: humanity hopes and fears, mankind await the verdict. It is rendered: Guilty upon every charge of the indictment; and heaven records the righteous sentence—Slavery must die, that the Union and liberty may live forever!
