Word
hachure
verb
Definition
to shade with or show by short lines used for shading and denoting surfaces in relief (as in map drawing) and drawn in the direction of slope
Example
"In the early years of the survey, hachuring was used to indicate the steepness of slopes on maps, whereas in later years, the more abbreviated and legible contour line was employed." (Robin E. Kelsey, The Art Bulletin, December 1, 2003)
Origin
As our example sentence indicates, hachuring is an old map drawing technique that was largely replaced in later years by the use of contour lines, or lines that connect points of similar elevation. The word "hachure," which can also be a noun referring to one of the short lines used in hachuring, comes from the French "hacher," meaning "to chop up" or "hash." This French word is also the source of the verbs "hash," which can mean "to chop (as meat and potatoes) into small pieces," among other meanings, and "hatch," meaning "to inlay with narrow bands of distinguishable material" and "to mark (as a drawing or engraving) with fine closely spaced lines."

Historical figure
Roger Casement
Sep 1, 1864 - Aug 3, 1916

Roger David Casement, known as Sir Roger Casement, CMG, between 1911 and 1916, was a diplomat and Irish nationalist. He worked for the British Foreign Office as a diplomat and later became a humanitarian activist, poet and Easter Rising leader. Described as the "father of twentieth-century human rights investigations", he was honoured in 1905 for the Casement Report on the Congo and knighted in 1911 for his important investigations of human rights abuses in Peru.

In Africa as a young man, Casement first worked for commercial interests before joining the British Colonial Service. In 1891 he was appointed as a British consul, a profession he followed for more than 20 years. Influenced by the Boer War and his investigation into colonial atrocities against indigenous peoples, Casement grew to mistrust imperialism. After retiring from consular service in 1913, he became more involved with Irish republicanism and other separatist movements. During World War I he made efforts to gain German military aid for the 1916 Easter Rising that sought to gain Irish independence.

He was arrested, convicted and executed for high treason. He was stripped of his knighthood and other honours.

The South-East Asian Theatre of World War II was the name given to the campaigns of the Pacific War in Burma, Ceylon, India, Thailand, the Philippines, Indochina, Malaya and Singapore. Conflict in this theatre began when the Empire of Japan invaded French Indochina in September 1940 and rose to a new level following the raid on Pearl Harbor, and simultaneous attacks on Hong Kong, the Philippines, Thailand, Singapore and Malaya on 7 and 8 December 1941. The main landing at Singora on the east side of the Isthmus of Kra preceded the bombing of Pearl Harbor by several hours. Action in the theatre officially ended on 9 September 1945.
