but is good for interior work. Its produce is too valuable 
as a fruit for the tree to be much used as timber, but much 
of the wood, especially of its roots, is a cabinet wood of 
great beauty, extremely hard and difficult to work. The 
tree grows to a height of 60 ft. and more ; the wood is a 
yellowish white colour with irregular dark blotches occa- 
sionally in the heartwood. The medullary rays are very 
fine and numerous.

Jackwood {Artocarpus integrifolia) , or Jack tree, attains a 
height of 80 to 100 ft., grows throughout India, and is also 
found in the Antilles and Brazil, where it goes by the name 
of Jaqueira. It is a large evergreen producing a coarse, 
yellowish brown wood, light at first and darkening in colour 
with age, sometimes known as Jacqueria wood. It is very 
durable, fairly hard, and used for a variety of purposes, 
chiefly for the manufacture of cheap furniture, and in 
Great Britain for cabinet work, backs of brushes, marquetry, 
etc. Kesistance to shear along fibres 672 lbs. per square 
inch. Crushing strength 3"4 tons, transverse strength 
3'04 tons, and coefficient of elasticity 445 tons per square 
inch (Prof. Unwin, Impl. Inst. Journal, Vol. V.). 
Weight about 43 lbs. per cubic foot. 
Hamileel or Hamillila {Berrya ammonilla) is one of the 
most durable and useful timbers of Ceylon, but is chiefly 
used for making casks. The medullary rays are broad, 
the colour varies from light to dark red, and the heartwood 
is well defined, hard and close grained, but apt to split ; it 
is very durable. The tree is also found in Burma and 
Southern India and goes by the general name of Trincomali 
wood. Resistance to shear along fibres 830 lbs. per square 
inch, crushing strength 3*4 tons, coefficient of transverse
