The United States has a major problem on its hands. True, Britain is facing a similar prob

lem, but for the timebeing it is in America that it is graver. The only way to solve it is through education. Negroes (黑人．should knowabout the contributions that black individuals and groups have made towards building America. This is of vitalimportance for their self-respect; and it is perhaps even more important for white people to know. For if you believethat a man has no history worth mentioning, it is easy to assume that he has no value as a man. Many people believe that, since the Negro's achievements do not appear in the history books, he did not haveany. Most people are taken aback when they learn that.Negroes sailed with Columbus, marched with the Spanishconquerors of South America and fought side by side with white Americans in all their wars. People are astonishedwhen you tell them about Phillis Wheatley, who learned English as a salve in Boston and wrote first-class poetry.They have never heard of Benjamin Banneker, a mathematician and a surveyor, who helped to plan the city ofWashington. There has been a tendency all along to treat the black man as if he were invisible. Little has beenwritten about the 5,000 American Negroes who fought in the Revolution against the British, but they were in everyimportant battle. In the Anglo-American War of 1812, at least one out of every six men in the U.S. Navy was aNegro. In the Civil War, more than 200,000 black troops fought in the Union forces. How, then, did the image of the Negro as a valiant fighting man disappear？ To justify the hideous institutionof slavery, slave-holders had to create the myth of the docile, slow-witted Negro, incapable of self-improvement, and even contented with his lot. Nothing could be further from the truth. The slave fought for his freedom at everychance he got, and there were numerous uprisings. Yet the myth of docility persisted. There are several other areas where the truth has been twisted or concealed. Most people have heard of theNegro, Carver, who invented scores of new uses for the lowly peanut. But whoever heard of Norbert Rillieux, whoin 1846 invented a vacuum pan that revolutionized the sugar-refining industry？ Or of Elijah McCoy, who in 1872invented the drip cup that feeds oil to the moving parts of heavy machinery？ How many people know that Negroesare credited with inventing such different items as ice creams, potato chips, the gas mask and the first traffic light？ Not many. As for the winning of the West, the black cowboy and the black frontiersman have been almost ignored, though film producers are becoming more aware of their importance. Yet in the typical trail crew of eight men thatdrove cattle from Texas to Kansas, at least two would have been Negroes. The black troops of the Ninth and TenthCavalry formed one-fifth of all the mounted troops assigned to protect the frontier after the Civil War. "Whatdifference does it make？" you may ask. A lot. The cowboy is the American folk-hero. Youngsters identify withhim instantly. The average cowboy film is really a kind of morality play, with good guys and bad guys and rightfinally triumphing over wrong. You should see the amazement and happiness on black youngsters' faces when theylearn that their ancestors really had a part in all that.
