For a wind-break the trees should be planted in double or 
single rows, 12ft. to 15ft. apart, when their evergreen branches will 
entwine and resist the most fierce wind. The tree is very sym- 
metrical in growth, and highly ornamental in paddocks, where they 
afford in copses or singly a good shelter for stock. As a road 
border, or in avenues, it also affords a striking effect. It stands 
clipping well. It grows quicker than the Olive tree; the gathering 
of its fruits, which are knocked down by means of long poles, is 
easier, while the pods can be bagged or stored away for a long time 
without loss. In the proximity of orchards, it moreover offers over 
the Olive tree the marked advantage of being pretty free from insect 
pests, and more especially the black scale that finds in the Olive 
a favourite host plant. This disadvantage has, however, now dis- 
appeared since the fly parasites of that scale have been successfully 
introduced into this State. 
The Carob trees are propagated from seeds, which, being hard, 
require soaking for a few days. When the germ begins to show 
they are sown in seed beds, preferably in ground with a hard sub- 
soil, so as to check the downward growth of the tap-root. After 
a fortnight or so the young plants begin to show. When about 
three feet high, in one year or two, they are transplanted in a 
nursery, cut back to 12 inches or so, and the year after they are 
grafted with scions from some prolific tree, bearing large pods. 
Unless this is done, many of the irees will prove sterile. The 
frequent unisexuality of the flowers accounts to some extent .for 
the want of productiveness in fruit of this plant when few trees 
exist, or this sterility may be traceable to insufficiency of lime or 
other substances in the soil. After a year or two in the nursery the 
young trees are planted out, suckers are rubbed off, and, after two 
or three years’ cultivation, will yield three to four ewts. of fruit 
without further cultivation. On the Swan the pods ripen in March, 
when blossoming also takes place. 
BRacHYCHITON PopuLNEUS—-One of the currajongs. From 
Gippsland to Southern Gippsland a splendid avenue tree, recom- 
mended for its pyramidal growth, evergreen shining foliage, some- 
what variable in shape, and short stout branches which render it 
almost wind-proof. Succeeds well on rocky and dry ground, and is 
comparatively easy to transplant even when of good size. Leaves 
eaten by pasture animals. Allied to the “flame-trees” of Kimberley; 
makes a gorgeous display of coral-like inflorescences. 
Tue Birrer OrancE (Citrus Bigaradia)—Very suitable for 
avenue planting in the towns of the citrus belt, and much used for 
that purpose in Southern Europe, where it is trained with a clear 
stem 6ft. to 8ft. high, and a regularly-shaped crown. Very attrac- 
tive on account of its beautiful aromatic foliage, delicious blossoms, 
which furnish the Neroli oil, and golden fruit, the rind of which is
