Dead Line

species and name

DEAD LINE. A phrase which probably originated during the Civil War. In some of the prison camps a line was drawn through or around the camp. If a prisoner attempted to cross the line he was shot at once. To the men it became the dead-line. In a figurative sense it applies to the age-limit of efficiency.

an English fishermen's name for the Alcyonium, a genus of polyps, the typical one of the family Alcyonidce, characterized by the polyps of the colony having eight hollow arms and eight mesenteries, and a skeleton composed of separate calcareous spic ules. It contains many well-known species, such as A. digitatum, or sea-finger (dead-men's-fin gers, known also to fishermen as dead-men's toes, and cow's-paps), and A. glomeratum. A common species on the United States Atlantic coast is A. carneum. The name is also applied to certain species of branching sponges.

a common name applied to the genus Lamium of the natural order Labiatm, mint family. It is an annual or peren

nial herb, of which there are about 40 species, all natives of the Old World. It has been naturalized in America, and several Species are found in waste places and cultivated ground from New Brunswick to Florida and west to Ontario, Minnesota and Arkansas. The best known species are L. purpureum and L. album, which are used in the northern parts of Europe as pot-herbs. A species of the genus Galeopsis (G. tetrahit) is called dead-nettle, as is one of the species of Stachys (S. palustris). It was an old belief that the hairs of the dead-nettle, when dry, caused irritation to the exposed parts of persons coming in contact with the plant, and that this, extending through the system, sometimes caused death; hence the name.
