What is meant by Plimsoll’s mark?

Plimsoll’s mark consists of a disk and letters painted in white on the outside of a British ship’s hull to indicate the limit to which the vessel may be loaded at various seasons in salt and in fresh water. It is, in other words, a “load line.” Plimsoll’s mark was named for Samuel Plimsoll (1824-1898), a British- statesman, who was noted for his load line reforms and who became known- as the “sailor’s friend” because of his efforts to get Parliament to pass legislation for the protection of seamen. His reforms were directed particularly against what he called “coffin ships,” that is, overloaded and unseaworthy vessels in which unscrupulous owners, protected by heavy insurance, risked the lives of, the crews everytime they put to sea. The act requiring Plimsoll’s mark was passed in 1876. Other nations soon followed suit in adopting similar protective measures and the merchant ships of nearly all countries are now required by law to bear a line on the outside of the vessel to show the depth to which it should sink when properly loaded. In 1930 the International Load Line Convention was signed in London. By 1941, when this convention was temporarily suspended because of war conditions, thirty-six countries had become parties to it. This convention provided for the placing of load lines on merchant ships engaged on international voyages. Is a zebra a light animal with dark stripes or a dark animal with light stripes? The ground color of the body of a zebra is a pale, yellowish brown and the stripes are black or dark brown. When the zebra and the ass are crossed the light tan predominates as the basic body color in the offspring. Therefore, in reply to this proverbial question, it may be said that the zebra is a light brown animal with black or dark brown stripes. The zebra, like the ass, is a member of the horse family. It is not a domestic animal, but, with considerable difficulty, it can be trained for riding and driving.
