19801 THOMAS: ARTOCARPUS 159

The tree is famed for its valuable timber. Its heartwood is considered to be next best to teak or rosewood in south India. Because of its excellent fibre and colour, it is best used in furniture making. The timber is used in building con- struction too. Door and window frames made of this wood last years. It is also used as fascia boards, rafters, purlins and ridges for houses and buildings. The bark is used in the tanning industry (Maheswari and Singh, 1965). A dye is ob- tained by boiling chipped wood and is used for colouring Buddhists' robes in Sri Lanka and Burma. In some places, the leaves form an important fodder for sheep and goats. The dried leaves are used in the preparation of compost manure in Kerala. In India and Assam, the trees are grown as shade trees in coffee and orange plantations and also as supports for pepper.

In summary, this is one of the most useful trees of the tropics. Researches on the industrial uses of the wood, nutritional potential of the fruit, its preservation and ripening characteristics, and feasible and successful vegetative propagational methods would well repay study.
