Acer negundo, the box-elder of North America, is a maple, and Acer platanoides, 
the Norway maple, is another. They have beautiful leaves, and flourish in cold, 
clamp situations. They will stand as much cold as we can give them in New South 
Wales. 
Aescultis califomica is the California buckeye or horse chestnut, dwarf in Sydney, 
but a large tree in moist rich soils in the cooler parts of the State. It has white flowers 
in trusses, and is one of the most lovely trees in the world. Therefore it is worth 
taking pains over. The true horse chestnut (Aesculm hippocastanum) is also only 
for the cooler parts of this State, in low-lying localities. Those who have seen it in 
its best development in Europe recognise it as a beautiful object, and it is well worthy 
of cultivation, being especially beautiful in the spring. In the summer with hot winds 
horse chestnuts are apt to be withered looking, but is not this a fault to which many 
deciduous trees are liable ? 
Ailanthus glandulosa is sometimes called the Tree of Heaven. It is a valuable 
tree, but liable to sucker, and hence should be kept away from cultivated ground, as it 
behaves like elms and poplars. It is very handsome, in a young state, and is one of 
the few trees well tested for dry situations, so that it is to be recommended for such 
trying situations hi many parts of the State; it will, however, grow almost anywhere. 
In Paris, where ifc is largely and successfully employed for avenue-planting, it is known 
as Vemix du Japon. 
The Cape Chestnut (Calodendron capense) is hardy, and is such a specially hand- 
some object when covered all over with its large mauve blossoms that it is worthy of 
abundant experiment. I believe it will grow in many parts of this State, and that it 
will stand a fair amount of dryness. 
The pecan nut (Carya oliviformis) is a handsome tree which yields an excellent 
edible nut. It requires cool, damp situations. 
The same localities are necessary for bhe proper development of the Spanish 
Chestnut (Costarica saliva), a handsome tree, yielding a nutritious nut which is 
specially acceptable when roasted. Australians are not a nut-eating people, but when 
they develop increased tendencies in this direction the Spanish or Sweet Chestnut tree 
will be very largely planted. At Mount Wilson the tree is perfectly at home. 
Then we come to the Catalpas (bignonioides and speciosa), beautiful American 
trees which come to us with a great reputation. C. speciosa is a hardier and bigger 
tree than C. bignonioides, and they both should be further tested as rapid-growing trees 
in cold, damp localities. Their reputation in New South Wales has so far come much 
below their American one, as it is found, so far, that they fail in dry weather, and 
will not stand our dry winds. 
CeUis australis, the lotus tree of South Europe, is a very dense growing, handsome 
tree. It stands dry and cold as well as hot situations, like silky oaks, and I look upon 
it r.s one of the most generally useful trees as yet imported into New South Wales.
