The Professional Memoirs Corps of Engineers, United States Army and Engineer Department at Large was published under this title from 1909 to 1919. From 1920 it was titled Military Engineer. The Military Engineer—since 1909 under its original masthead Professional Memoirs, and since January 1920 in its current form as the official journal of Society of American Military Engineers (SAME)—has been the leading voice championing the contributions, the achievements, and the legacy of military engineers and those aligned with ensuring the national security of the United States. At the time of publication, Brig. Gen. Abbot was Professor of Hydraulic Engineering at the George Washington University. This article is a fascinating discussion of "When, as in the case of a canal feeder, an irrigation ditch, or the head and tail races of a water power establishment, the local conditions determining the slope to be given to the water surface and the maximum volume to be accommodated, the economical problem arises what should be the relative dimensions of the cross section to require the minimum amount o excavation, and hence the minimum outlay....Where the route follows the contours of a steep hill side, the excess in excavation above the water level due to the larger surface width may be reduced materially by a steeper revetment of the mass above. ...although no general rule can be formulated. Each case must be judged upon its own merits." Henry Larcom Abbot (August 13, 1831 – October 1, 1927) was a military engineer and career officer in the United States Army. Abbot attended West Point and graduated second in his class (which included Jeb Stuart and G. W. Custis Lee) with a degree in military engineering in 1854. He initially wanted to join the Artillery, but shortly after graduation, a classmate convinced him to choose the Engineers. He conducted several scientific studies of the Mississippi River with captain, later Major General Andrew A. Humphreys. He served in the Union Army during the American Civil War and was appointed brevet brigadier general of volunteers for his contributions in engineering and artillery. In 1866 he received additional brevet appointments as major general of volunteers and brigadier general in the Regular Army. In January 1865, General Alfred H. Terry requested General Abbot accompany his expeditionary force to Fort Fisher. Abbot commanded a provisional brigade of siege artillery during the successful Second Battle of Fort Fisher. He created the army's Engineer School of Application there, and served on numerous boards, including the Board on the Use of Iron in Permanent Defenses, the Board of Engineers for Fortifications, the Gun Foundry Board, the Board on Fortifications and Other Defenses, and the Board of Ordnance and Fortifications. Abbot's influence can be seen in many facets of the coast defense systems of the United States of that period, particularly in the submarine mine system, and in the use of seacoast mortars. Abbot advocated the massing of 16 mortars in 4 sets of 4, which would fire simultaneously at the enemy warships. The plan became known as the "Abbot Quad". After his retirement, After his retirement from the Army, Abbot continued to work as a civil engineer and was employed as a consultant to Comité Technique and Comité Statutaire for the locks on the Panama Canal between 1897 and 1900. He was appointed to the Board of Consulting Engineers by Theodore Roosevelt and served between 1905 and 1906 after the Americans took control of building the canal. He was given the task to prepare plans for canal construction and was able to convince Roosevelt and Secretary of War William Howard Taft to approve a lock canal rather than a sea-level canal. In 1915, he was part of the Panama Canal Slide Committee. He was elected a Fellow of the American Academy of Arts and Sciences in 1863. Condition: Good.
