The editors and editorial helpers of the _Port Folio_ from the death of Dennie until 1827, when the magazine finally ceased, were Paul Allen, Nicholas Biddle, Dr. Charles Caldwell, Thomas Cooper, Judge Workman, John Elihu Hall, and his three brothers James, Thomas Mifflin, and Harrison. JOHN BLAIR LINN (1777-1804), the author of the "Powers of Genius" (1801), a popular work which was splendidly reprinted in London,[13] was the son of Dr. William Linn, of Shippensburg, who presided successively over the destinies of three colleges--Washington, Rutgers and Union--and was for many years a regent of a fourth--the University of the State of New York. John Blair was graduated from Columbia, read law with Alexander Hamilton, wrote an unsuccessful drama, "Bourville Castle," and on June 13, 1799, was installed as joint-pastor of the First Presbyterian Church, Philadelphia. He engaged in controversy with Joseph Priestley, but his best achievements were "Valerian," a narrative poem, and "The Death of Washington" (1800). John Blair Linn was a brother-in-law of Charles Brockden Brown. A biographical sketch of him was written for the _Port Folio_ in 1809 (page 21), and again in 1811 (89-97). Brown also published a review of his life and work in the _Literary Magazine_, Vol. II, page 554. [13] The Powers of Genius, a poem in three parts, by John Blair Linn, A.M. Albion Press. Printed by J. Cundee, Ivy Lane, for F. Williams, Stationers' Court, and T. Hurst, Paternoster Row, 1804. JOHN SHAW (1778-1809) was born in Annapolis, May 4, 1778, and lost at sea January 10, 1809. He studied medicine in the University of Pennsylvania, and visited Algiers as a ship-surgeon in 1798. He died on a voyage to the Bahama Islands. The best poem that he contributed to the _Port Folio_ was: Who has robbed the ocean cave, To tinge thy lips with coral hue? Who from India's distant wave For thee those pearly treasures drew? Who, from yonder Orient sky, Stole the morning of thine eye? Thousand charms thy form to deck, From sea, and earth, and air are born; Roses bloom upon thy cheek, On thy breath their fragrance borne. Guard thy bosom from the day, Lest thy snows should melt away. But one charm remains behind, Which mute earth can ne'er impart; Nor in ocean wilt thou find, Nor in the circling air, a heart. Fairest! wouldst thou perfect be, Take, oh take that heart from me. All his offerings to the _Port Folio_ were signed "Ithacus." His poems were collected and published in 1810, together with a memoir and extracts from his foreign correspondence. FRANCIS COPE contributed essays to the _Port Folio_ in 1812. He was an occasional writer for several years, signing his papers with the initials "C. F."
