Gun Construction on the "Woodbridge System".

A Sketch for presentation to Board of Heavy Ordnance, Appointed under the Act of Congress, Making appropriations for Fortifications, Etc. approved March 3, 1881. 2 plates. 8vo. Modern wrappers. 31 pp. Washington,

After some years and experiments on a smaller model, a 10" steel muzzle-loading gun was eventually constructed to Dr. Woodbridge's design. However, flaws were noted in a report on it of 1876. Woodbridge argues that the test gun - a compromise 10" instead of 12" due to budget curtailment - had been poorly constructed. He also suggests that the author of the test report possessed poor health and failing mental powers.
