and in considerable demand for building Chinese Coffins and 
such purposes. Howard Newton says it bends easily and is useful 
for planking vessels as it stands well in water and is buoyant. His 
experiments show that it is stronger than Billian but not quite so 
tough.

A. integrifolia, Linn f. Jack. Nangka. 
A well known fruit tree, common round villages. It attains a 
fairly large size, though not as big as some of the other species, and 
branches rather low down usually. 
The heartwood is yellow at first becoming brown with age, pores 
large scattered and in rows and surrounded by softer tissue, rays 
fine and close lighter in colour than the intermediate tissue rings, 
usually distinct. Sapwood large white soft and useless. 
The tree grows fast everywhere. Gamble gives the weight at 
39.5 lbs. ; Brandis 40 lbs. per cubic foot; Singapore 38 lbs. 15 ozs. to 
35 lbs. 8 ozs. It is not eaten by whiteants. 
A good furniture wood for cabinets, tables etc., also used for 
canoes in India. This wood is much in favour in Ceylon and In- 
dia, but it appears to be very little used here although it might be 
had in considerable quantity and' would be worth planting in 
forestsfor its timber alone. Plants, however, planted out in forests 
in Singapore were speedily destroyed by deer and mouse deer, 
(pelandok) which like goats and cattle are remarkably fond of its f 
leaves. 
A. polyphemia, Pers. Champedak. 
A well known fruit tree with smooth white cylindrical heads of 
fruit, commonly cultivated and wild in many parts of the Peninsula 
and Sumatra. When grown in open country it usually forms a 
short stem and branches much low down as Jack is apt to, but in 
the wild state in the denser forest form a tall straight tree, thirty 
or forty feet tall, roughened with knots from which flowers and 
fruits have sprung. 
The timber much resembles that of Jack, but the pores are 
slightly larger and more numerous, the rays too are rather wider 
and more irregular in width. Weight 37 lbs. 2 ozs. to 47 lbs. 7 ozs. 
It is good for house building and also used for boats. 
A. inctsa , Linn. Breadfruit, Sukun. 
Cultivated here, but does not seem to do very well, the tree 
attaining no great size and the fruit being poor. The timber re- 
sembles that of the Jack, but is not so good here at least. I have 
seen very line samples in Brazil where it was used for blades of 
paddles and other purposes. 
A. rigida , BI. Tampunei, Monkey Jack, 
A well known fruit tree, with yellow globose fruits covered with 
short blunt processes, the seed wrapped in a sweet yellow aril, very
