Century Dictionary and Cyclopedia

1. n. A covered chair serving as a vehicle for carrying one person who sits within it, the inclosure being therefore of much greater height than width: it is borne on two poles, which pass through rings secured to the sides, and usually by two bearers. These chairs were first introduced in western Europe in the sixteenth century (first seen in England in 1581, and regularly used there from 1634), but their use was greatly extended in the eighteenth century, when they were the common means of transportation for ladies and gentlemen in the cities of England and France. They were often elaborately decorated, with paintings by artists of note, panels of vernis Martin, and the like, and lined with elegant silks. Similar chairs, carried on the shoulders of two or more bearers, have long been in use in China.
2. n. A hand-barrow with a deep basket-like bottom made of barrel-hoops, used to carry fish. It has been used since the eighteenth century to carry fish from the beach over the sand to the flakes.
