reserve. An arrangement is under progress to provide a second main pipe of the 
aqueducts, in order that the tree plantatious in the special reserves of the Botanic Garden, 
and in that part of the Government House domain inclining to the St. Kilda road, may 
enjoy already this summer a similar benefit of irrigation. In the last-mentioned reserves, 
not only extensive lines of avenue trees have been arrayed along the walks more recently 
laid out, but also the grassy undulations and slopes have widely and permanently been 
planted with Firs and other coniferous trees, and with Mediterranean and American Oaks, 
many evergreen. 
The means for these extensive operations on the grounds also beyond the garden 
area have been exclusively supplied from the votes of this department. The kinds of 
trees chosen, and the number planted, are indicated on the attached plan. Thus, the lines 
of avenues now established in the Garden and in the surrounding reserves comprise the 
following 42 kinds of trees : the Illawarra Flame tree, the Poplar-Bottle tree, Pithecolo- 
bium pruinosum, the British Birch, Grevillea robusta, Gleditschia, the Sugar Maple, the 
Sycamore Maple, Ailantus glandulosa, the Azedarach or White Cedar, the spreading Black 
Poplar, the Abele Poplar, the Moreton Bay Fig tree, Hymenosporuin flavum, the British 
Elm, the Bluegum tree, the Stringybark tree, the West Australian Redgum tree, the Cork 
Oak, Powlonia imperialis, the columnar and the spreading Mediterranean Cypress, the 
tall Cupressus macrocarpa and Cupressus Lawsoniana of California, the Himalayan 
Cupressus torulosa, the Halepo Pine, the Stone Pine, the Japan Gingko, the Wellingtonia 
or Big tree, the Bunya Bunya tree, the Canary Islands Fir, Pinus excelsa from the Indian 
Highlands, the Deodar Cedar, the Walnut tree, the Weeping Willow, the Locust tree, 
the true Plane, the North America Wax Ash, and Pinus insignis of California. 
The three last-mentioned kinds have shown such a celerity of growth that I 
cannot refrain from drawing special attention to their superiority over very many other 
eligible avenue plants. Thus Pinus insignis has grown here with about twice the rapidity 
of a Cluster pine, and thrice that of a Scotch Fir. Planes and Wax Ashes, if once estab- 
lished, could be multiplied locally with the greatest ease from cuttings. 
Irrespective of these kinds, a number of miscellaneous trees of deciduous foliage, 
including Horse Chesnut trees. Sweet Chesnut trees, Limes, &c., are mingled with the 
evergreen tree vegetation on the causeway at the Yarra banks. Some additional lines 
of trees are projected on the northern reserve, and for these may be chosen such superior 
species as the Sycamore Fig tree, which is the favored tree along roadsides and around 
dwellings in Egypt, where single lines of this tree are found sufficient to overshade broad 
streets with its expansive ramifications. 
As further eligible for avenues may be mentioned the Lemon-scented Eucalyptus, 
the Karri Gum tree of West Australia, next to Wellingtonia probably the most gigantic 
tree of the globe ; the Cardwellia sublimis and other noble trees recently discovered in the 
jungles of the north-east coast, and probably hardy here ; especially also the Manna Ash, 
which has proved here, as. might be expected from its South European origin, much less 
susceptible to the effects of scorching winds than its middle European congener ; further, 
Azadirachta trees, the Siris Acacia, Amyris terebinthifolia, several North American trees, 
especially from the southern states, some here already under test of experiment ; the 
Chinese evergreen Elm, the Basket Willow, Oranges, several kinds of true Oaks, Cupressus 
Goveniana, the most rapid and at the same time perhaps the most spreadingly growing of 
all lofty Cypresses ; Flindersia trees of several kinds ; several Ekeocarpi, hardy and of tall 
growth, especially Elmocarpus holopetalus of East Gipps Land, and of the southern part of 
New South Wales ; perhaps also Eucryphia Moorei, and other trees, such as continued 
and successive trials may point out as adapted to our clime. 
And here the prospects are most cheering. For, with due regard to aspect, soil 
and shelter, we may select for overshading our roads and streets from an almost endless 
number of kinds of tree within the broad girdle of the whole temperate and also the sub-
