CHENEY, JOHN VANCE (1848), public librarian of San Francisco. He has published two dainty books of fascinating, graceful, and wayward verse_, Thistledrift_ and _Wood Blooms_. See also _Poems of Wild Life_, “Canterbury Poets.” CLARK, LEWIS GAYLORD (1810-1873). Appointed editor of the _Knickerbocker Magazine_ in 1834. He brought the magazine into fame, and gathered around him as contributors, Longfellow, Irving, Bryant, Halleck, Morris, and other well-known men. His published works in book form are _Knickerbocker Sketch-Book_, and _Knick-Knacks from an Editor’s Table_. CLARK, WILL W., the “Frisbee” and “Gilhooley” of the _Pittsburg Leader_. CLEMENS, SAMUEL LANGHORNE, born 1835. A true citizen of the United States, he began at the bottom of the ladder and has worked his way to the top. After receiving a meagre education at a village school, he was apprenticed to a printer at the age of thirteen, and for three years “stuck type.” In 1851 he took to the Mississippi, earning his living as a pilot, and later on tried mining and editing. Under the pseudonym “Mark Twain” he began to publish the work which has earned for him the right to be considered the greatest humorous writer of the century. _The Jumping Frog and other Sketches_ was his first book, appearing in 1867, and this he has followed with a splendid line of successes down to _The American Claimant_, which has just appeared. Messrs. Chatto & Windus publish his works in England, and Webster & Co. in America. CLIFTON, WILLIAM (1772-1799), a satirical writer of prose and verse. Author of _The Group_, _The Rhapsody of the Times_, and an unfinished poem, “Chimeriad.” COTES, MRS. E. C., “SARAH JEANNETTE DUNCAN” (1863). Miss Duncan, a native of Brantford, Ontario, Canada, did her first literary work on the _Toronto Globe_, and, after occupying positions on the staff of the _Globe_ and _Washington Post_, spent a session at Ottawa as special correspondent of the _Montreal Star_. This newspaper training is clearly shown in her two clever books, _A Social Departure_ and _An American Girl in London_. The first is an original and wholly unconventional account of travel, telling how she, in company with another girl, went round the world. The other book is an equally bright description of her doings in London. COX, SAMUEL SULLIVAN (“SUNSET COX”), born 1824, and died 1889. A lawyer, journalist, and politician. He served the United States as diplomatist in Peru and Turkey, and wrote and spoke much that was witty. He published _The Buck-Eye Abroad_, _Why We Laugh_, _A Search for Winter Sunbeams_, _Arctic Sunbeams_, _Orient Sunbeams_, and _The Isles of the Princes_—the last three bright and laughable accounts of his travels in many lands. They are published by G. P. Putnam’s Sons, New York and London.
