but, nevertheless, it is done. This tree appears first to have been found in the 
Molucea Islands, Dutch East Indies; but it has a large range, extending from 
Ceylon to the Sandwich Islands, as well as to this country. Probably there are 
variations in its growth and habit; but the tree is the same. As has been 
already stated, it grows to a great height, is very conspicuous in the scrubs, 
the leaves having a silvery appearance when ruffled by the wind, as they are 
densely meally beneath. They are on long petioles or stalks, are large, entire, 
lobed; the fruit is large, separate, and discloses three roundish nuts, which are 
about 1 inch in diameter, having a hard shell. 
These are candle nuts, and they remain sound on the ground for a long 
time. The preceding year’s nuts may be collected at the time the fresh crop 
falls. The natives of North Queensland, whose name for them is “ nabala,”’ 
do not esteem the nuts as edible, and seldom eat them. It is not advisable for 
anyone to eat many, on account of their purgative and other properties, but 
one or two may be eaten by most persons, and relished, without bad effects. 
The oil contained in the kernel is used as a drying oil for paint, and is known 
as country walnut oil and artists’ oil. In Ceylon it is called Kekune oil, and 
in the Sandwich Islands Kubul oil.- The nut is said to be used by the Poly- 
nesians as a candle, a wick being placed in the centre for the purpose of 
ignition—hence, probably, the vernacular name, ‘“‘candle nut.’’ This is certainly 
not a nut for the table, but it is valuable on account of its oil. Being indige- 
nous to our district, there is no reason why the nuts should not be collected 
and forwarded to market by those settlers who live near the scrubs. The tree 
is often planted in the more southern parts of this colony as an ornamental 
one, and it certainly forms a very effective shade for large gardens or lawns. 
It is not suited for exposed situations, nor is it, I believe, a long-lived tree, but 
it has a rapid growth, and this is often a desideratum. This tree is among the 
first to spring up after heavy scrub has been felled, and very often commands 
the situation afterwards. Candle nuts exist in many places where the primeval 
forest has been cleared and left to the renewing powers of Aleurites.
