A speech that turned a rally into a crusade

The following is excerpted from Martin Luther King Jr.'s ''I have a dream'' speech: I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin, but by the content of their character.

I have a dream today.

I have a dream that one day the state of Alabama, whose governor's lips are presently dripping with the words of interposition and nullification, will be transformed into a situation where little black boys and black girls will be able to join hands with little white boys and white girls and walk together as sisters and brothers.

I have a dream today.

I have a dream that one day every valley shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight and the glory of the Lord shall be revealed, and all flesh shall see it together.

This is our hope. This is the faith with which I return to the South. With this faith we will be able to hew out of the mountains of despair a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to work together, to pray together, to struggle together, to go to jail together , to stand up for freedom together, knowing that we will be free one day.

This will be the day when all of God's children will be able to sing with new meaning, ''My country 'tis of thee, sweet land of liberty, of thee I sing. Land where my fathers died, land of the pilgrim's pride, from every mountainside, let freedom ring.''

And if America is to be a great nation, this must become true. So let freedom ring from the prodigious hilltops of New Hampshire! Let freedom ring from the mighty mountains of New York! Let freedom ring from the heightening Alleghenies of Pennsylvania!

Let freedom ring from the snowcapped Rockies of Colorado!

Let freedom ring from the curvaceous peaks of California!

But not only that; let freedom ring from Stone Mountain of Georgia!

Let freedom ring from every hill and mole hill of Mississippi. From every mountainside, let freedom ring.

When we let freedom ring, when we let it ring from every village and every hamlet, from every state and every city, we will be able to speed up that day when all of God's children, black men and white men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing in the words of that old Negro spiritual, ''Free at last! Free at last! Thank God almighty, we are free at last!''
