LEVANT (from the French use of the participle of lever, to rise, for the east, the orient), the name applied widely to the coastlands of the eastern Mediterranean Sea from Greece to Egypt, or, in a more restricted and commoner sense, to the Mediterranean coastlands of Asia Minor and Syria. In the 16th and 17th centuries the term “High Levant” was used of the Far East. The phrase “to levant,” meaning to abscond, especially of one who runs away leaving debts unpaid, particularly of a betting man or gambler, is taken from the Span. levantar, to lift or break up, in such phrases as levantar la casa, to break up a household, or el campo, to break camp.
LEVASSEUR, PIERRE EMILE (1828- ), French economist, was born in Paris on the 8th of December 1828. Educated in Paris, he began to teach in the lycée at Alençon in 1852, and in 1857 was chosen professor of rhetoric at Besançon. He returned to Paris to become professor at the lycée Saint Louis, and in 1868 he was chosen a member of the academy of moral and political sciences. In 1872 he was appointed professor of geography, history and statistics in the Collège de France, and subsequently became also professor at the Conservatoire des arts et métiers and at the École libre des sciences politiques. Levasseur was one of the founders of the study of commercial geography, and became a member of the Council of Public Instruction, president of the French society of political economy and honorary president of the French geographical society.
His numerous writings include: Histoire des classes ouvrières en France depuis la conquête de Jules César jusqu’à la Révolution (1859); Histoire des classes ouvrières en France depuis la Révolution jusqu’à nos jours (1867); L’Étude et l’enseignement de la géographie (1871); La Population française (1889-1892); L’Agriculture aux États-Unis (1894); L’Enseignement primaire dans les pays civilisés (1897); L’Ouvrier américain (1898); Questions ouvrières et industrielles sous la troisième République (1907); and Histoire des classes ouvrières et de l’industrie en France de 1789 à 1870 (1903-1904). He also published a Grand Atlas de géographie physique et politique (1890-1892).
LEVECHE, the name given to the dry hot sirocco wind in Spain; often incorrectly called the “solano.” The direction of the Leveche is mostly from S.E., S. or S.W., and it occurs along the coast from Cabo de Gata to Cabo de Nao, and even beyond Malaga for a distance of some 10 m. inland.
LEVÉE (from Fr. lever, to raise), an embankment which keeps a river in its channel. A river such as the Mississippi (q.v.), draining a large area, carries a great amount of sediment from its swifter head-streams to the lower ground. As soon as a stream’s velocity is checked, it drops a portion of its load of sediment and spreads an alluvial fan in the lower part of its course. This deposition of material takes place particularly at the sides of the stream where the velocity is least, and the banks are in consequence raised above the main channel, so that the river becomes lifted bodily upwards in its bed, and flows above the level of the surrounding country. In flood-time the muddy water flows over the river’s banks, where its velocity is at once checked as it flows gently down the outer side, causing more material to be deposited there, and a long alluvial ridge, called a natural levée, to be built up on either side of the stream. These ridges may be wide or narrow, but they slope from the stream’s outer banks to the plain below, and in consequence require careful watching, for if the levée is broken by a “crevasse,” the whole body of the river may pour through and flood the country below. In 1890 the Mississippi near New Orleans broke through the Nita crevasse and flowed eastward with a current of 15 m. an hour, spreading destruction in its path. The Hwang-ho river in China is peculiarly liable to these inundations. The word levée is also sometimes used to denote a riverside quay or landing-place.
