ing trees of this genus; the first named comes from the 
mountains of East Africa, and the second, J. virginiana, 
the Canadian Red Cedar, is also found in the United 
States of America. Jnniperus chinensus, the Chinese 
juniper, in some situations grows into quite a fine tree, 
in others where conditions are not favourable, it is only 
a shrub with procumbent branches. Jnniperus afncana 
does well, also Jnniperus hibemiea , the Irish Juniper, of 
compact habit, and foliage with glaucous tints ; it is rather 
slow in growth. A long sloping bank on a terrace at the 
back of Parliament House has been planted with Jiini- 
perus procumbenSy also known as J. prostrata , this plant 
as its name indicates has a trailing habit; hundreds of 
plants have been used and the whole bank will soon be 
covered with their bluish green, or steel blue foliage. An- 
other fine tree is Retinospora plumosa y a Japanese conifer 
of dense growing habit, the fcliage of which is plumed 
or feathery; some dwarf growing forms seen were very 
beautiful shrubs, with plumed ends of foliage. Sequoia 
is a small genus of Californian conifers consisting of two 
species: Sequoia gigantea (the Big Tree), and Sequoia 
sempervirens (Californian Redwood) ; S. gigantea is re- 
puted to be the largest of known trees. It is stated that 
a prostrate tree, one that had blown down, was measured 
in California and found to be 435 feet in length, and 110 
feet in circumference at base. At Canberra many Sequoia 
gigantea have been planted, and are making fine trees ; 
Sequoia sempervirens also promises well. 
Thuya orientals and its var. aurea , the golden form, 
are doing well ; they belong to the type vernacularly known 
as the Book Cypresses from the flattened appearance of 
the branch lets. I have left the Pinus, or true Pine family, 
rather late; this is a large genus, comprising over .50 
species, with numerous forms or sub-species. The chief 
kinds grown at Canberra, are Pinus radiata, or Pi>nus in - 
signus, as it is often called, indigenous in South Cali- 
fornia, where it is known as the Monterey Pine. It is a 
handsome species with bright green needle-like foliage, the 
tree is of rapid growth, and bushy habit when young; it 
is planted largely in the Capital City for wind breaks, 
also at Mount Stromlo, on the slopes of which a forestry 
plantation of a million trees shows up well. Pinus can - 
ariensis, the Canary Island Pine, is also being planted, 
any many fine trees may be seen. In some situations this 
beautiful tree will grow very quickly, even faster than P. 
radiata. Other Pinus being tried are P. flexilis , the 
Limber Pine, and Pinus ponder osa y the Yellow or Bull 
Pine. I have arranged to send Mr. Bruce seed of Pinus
