According to "A Bibliographical Checklist of American Negro Poetry," compiled by Mr. Arthur A. Schomburg, more than one hundred Negroes in the United States have published volumes of poetry ranging in size from pamphlets to books of from one hundred to three hundred pages. About thirty of these writers fill in the gap between Phillis Wheatley and Paul Laurence Dunbar. Just here it is of interest to note that a Negro wrote and published a poem before Phillis Wheatley arrived in this country from Africa. He was Jupiter Hammon, a slave belonging to a Mr. Lloyd of Queens-Village, Long Island. In 1760 Hammon published a poem, eighty-eight lines in length, entitled "An Evening Thought, Salvation by Christ, with Penettential Cries." In 1788 he published "An Address to Miss Phillis Wheatley, Ethiopian Poetess in Boston, who came from Africa at eight years of age, and soon became acquainted with the Gospel of Jesus Christ." These two poems do not include all that Hammon wrote. The poets between Phillis Wheatley and Dunbar must be considered more in the light of what they attempted than of what they accomplished. Many of them showed marked talent, but barely a half dozen of them demonstrated even mediocre mastery of technique in the use of poetic material and forms. And yet there are several names that deserve mention. George M. Horton, Frances E. Harper, James M. Bell and Alberry A. Whitman, all merit consideration when due allowances are made for their limitations in education, training and general culture. The limitations of Horton were greater than those of either of the others; he was born a slave in North Carolina in 1797, and as a young man began to compose poetry without being able to write it down. Later he received some instruction from professors of the University of North Carolina, at which institution he was employed as a janitor. He published a volume of poems, "The Hope of Liberty," in 1829. Mrs. Harper, Bell and Whitman would stand out if only for the reason that each of them attempted sustained work. Mrs. Harper published her first volume of poems in 1854, but later she published "Moses, a Story of the Nile," a poem which ran to 52 closely printed pages. Bell in 1864 published a poem of 28 pages in celebration of President Lincoln's Emancipation Proclamation. In 1870 he published a poem of 32 pages in celebration of the ratification of the Fifteenth Amendment to the Constitution. Whitman published his first volume of poems, a book of 253 pages, in 1877; but in 1884 he published "The Rape of Florida," an epic poem written in four cantos and done in the Spenserian stanza, and which ran to 97 closely printed pages. The poetry of both Mrs. Harper and of Whitman had a large degree of popularity; one of Mrs. Harper's books went through more than twenty editions.
