Truly has it been said, "knowledge is power." But it is not like the withering curse of a tyrant's power; not like the degrading and brutalizing power of the slave-driver's lash, chains, and thumb-screws; not like the beastly, demonical power of rum, nor like the brazen, shameless power of lust; but a power that elevates and refines the intellect; directs the affections; controls unholy passions; a power so God-like in its character, that it enables its possessor to feel for the oppressed of every clime, and prepares him to defend the weak and down-trodden. What but ignorance renders the poor slave so weak and inefficient in claiming his right to liberty, and the possession of his own being! Nor will that God who is "no respecter of persons," hold him guiltless who assumes unlimited control over his fellow. The chain of Slavery which fetters every slave south of Mason and Dixon's Line, is as closely linked around the master as the slave. The time has passed by when African blood alone is enslaved. In Virginia as well as in some other slave States, there is as much European blood in the veins of the enslaved as there is African; and the increase is constantly in favor of the white population. This fact alone speaks volumes, and should remind the slave-breeding Southerner of that fearful retribution which must sooner or later overtake him. In September, 1817, I commenced business in Rochester. Having rented a room of Mr. A. Wakely, I established a meat market, which was supplied mostly by my former employer, Mr. Comstock, and was liberally patronized by the citizens; but there were butchers in the village who appeared to be unwilling that I should have any share in public patronage. Sometimes they tore down my sign, at others painted it black, and so continued to annoy me until after I had one of their number arrested, which put a stop to their unmanly proceedings. The village was now rapidly increasing, and yet the surrounding country was mostly a wilderness. Mr. E. Stone, who then owned the land on the east side of the river, thought his farm a very poor one; he, however, commenced clearing it in the midst of wild beasts and rattlesnakes, both of which were abundant, and in a few years was richly rewarded for his labor, in the sale of village lots, which commanded high prices. In the summer of 1818, I commenced teaching a Sabbath School for the neglected children of our oppressed race. For a while it was well attended, and I hoped to be able to benefit in some measure the poor and despised colored children, but the parents interested themselves very little in the undertaking, and it shortly came to naught. So strong was the prejudice then existing against the colored people, that very few of the negroes seemed to have any courage or ambition to rise from the abject degradation in which the estimation of the white man had placed him.
