The New International Encyclopædia/Jack Tree

JACK, JAK, or JACA, TREE (East Indian jaca). Artocarpus integrifolia. An East Indian tree of the same genus as the breadfruit (q.v.), but larger. The fruit, which is very large, and weighs from 5 to 50 pounds, sometimes 70 pounds, is produced in great abundance. It resembles the breadfruit, but has a pulp of somewhat unpleasant flavor. It forms a great part of the food of the natives in some parts of India, Ceylon, etc. The seeds, which lie immediately under the rind, are very palatable when roasted. The timber, which is yellowish, strong, and ornamental, is used for almost every purpose, and is exported for making musical instruments, cabinet-work, the backs of brushes, marqueterie floors, etc. To supply the demand of it, the tree is being planted in many tropical countries.
