Besides, the above the works, he wrote numerous scientific pamphlets and elaborate professional reports. He published over seventy articles in Johnson's "Universal New Cyclopedia" that illustrated Barnard's mental strength, his versatility of talents, and his prodigious powers of production. The studies include treatises on Bridge-building and Harbor, Breakwater, Jetty, and Lighthouse construction; complex mathematical dissertations on Calculus, Aeronautics, Imaginaries, Gyroscope, and the Theory of Tides; and valuable histories of the Army Corps of Engineers, Lighthouse Board, and the battle of Bull Run.
