Freedom invents—slavery forgets. The problem of the slave is to do the least work in the longest space of time. The problem of free men is to do the greatest amount of work in the shortest space of time. The free man, working for wife and children, gets his head and his hands in partnership.

Freedom has invented every useful machine, from the lowest to the highest, from the simplest to the most complex. Freedom believes in education—the salvation of slavery is ignorance.

The South always dreaded the alphabet. They looked upon each letter as an abolitionist, and well they might. With a scent keener than their own bloodhounds they detected everything that could, directly or indirectly, interfere with slavery. They knew that when slaves begin to think, masters begin to tremble. They knew that free thought would destroy them; that discussion could not be endured; that a free press would liberate every slave; and so they mobbed free thought, and put an end to free discussion and abolished a free press, and in fact did all the mean and infamous things they could, that slavery might live, and that liberty might perish from among men.

You are now citizens of many of the States, and in time you will be of all. I am astonished when I think how long it took to abolish the slave-trade, how long it took to abolish slavery in this country. I am also astonished to think that a few years ago magnificent steamers went down the Mississippi freighted with your fathers, mothers, brothers, and sisters, and maybe some of you, bound like criminals, separated from wives, from husbands, every human feeling laughed at and outraged, sold like beasts, carried away from homes to work for another, receiving for pay only the marks of the lash upon the naked back. I am astonished at these things. I hate to think that all this was done under the Constitution of the United States, under the flag of my country, under the wings of the eagle.

The flag was not then what it is now. It was a mere rag in comparison. The eagle was a buzzard, and the Constitution sanctioned the greatest crime of the world.

I wonder that you—the black people—have forgotten all this. I wonder that you ask a white man to address you on this occasion, when the history of your connection with the white race is written in your blood and tears—is still upon your flesh, put there by the branding-iron and the lash.

I feel like asking your forgiveness for the wrongs that my race has inflicted upon yours. If, in the future, the wheel of fortune should take a turn, and you should in any country have white men in your power, I pray you not to execute the villainy we have taught you.

One word in conclusion. You have your liberty—use it to benefit your race. Educate yourselves, educate your children, send teachers to the South. Let your brethren there be educated. Let them know something of art and science. Improve yourselves, stand by each other, and above all be in favor of liberty the world over.

The time is coming when you will be' allowed to be good and useful citizens of the Great Republic. This is your country as much as it is mine. You have the same rights here that I have—the same interest that I have. The avenues of distinction will be open to you and your children. Great advances have been made. The rebels are now opposed to slavery—the Democratic party is opposed to slavery, as they say. There is going to be no war of races. Both parties want your votes in the South, and there will be just enough negroes without principle to join the rebels to make them think they will get more, and so the rebels will treat the negroes well. And the Republicans will be sure to treat them well in order to prevent any more joining the rebels.

The great problem is solved. Liberty has solved it—and there will be no more slavery. On the old flag, on every fold and on every star will be liberty for all, equality before the law. The grand people are marching forward, and they will not pause until the earth is without a chain, and without a throne.
