Ill 
taken as a type of the northern New South Wales form, is usually 40 to 50 feet 
high, and also has a diameter of 2 or 3 feet. In Tasmania and Victoria it is as large 
and larger than those of the southern mountain districts of New South Wales. 
Distribution.— The Blackwood is best known as a Tasmanian and Victorian 
tree. It also occurs in South Australia. It is extensively distributed in the 
southern maintainous districts of New South Wales. It then seems to skip over 
the immediate neighbourhood of Sydney, hut reappears in the rising country at the 
hack of Port Stephens, and is extensively distributed in the table-land of New 
England, extending into Queensland. From Port Stephens to Queensland it is 
frequently found wherever the elevation is not less than 2,500 feet. What its 
precise western boundary is, we do not know at present; hut I have seen it from 
Tenterfield, Glen Innes, Boggabri, and near Armidale. It is hv no means rare on 
the western slopes of the Blue Mountains, not on the' sandstone ; hut on the 
granite, following up the granite gullies where there is a little seepage. It occurs 
abundantly in the Mudgee district. It is plentiful in the Bichmond River district, 
occurring in places of no great elevation, and at no distance from the sea. As far as 
southern New South Wales and Gippsland are concerned, the Blackwood must be 
considered as a mountain species, though it occurs occasionally in the low coast land ; 
hut there it never attains any size. It varies a good deal in mode of growth, 
according to situation and geological formation. In the rich humus of the jungle 
of the mountain slopes, it attains a height of from 60 to 80 feet, and in Gippsland, 
along the boundary of New South Wales and Victoria, localities may he found 
where it attains a height of 120 feet, and a diameter of nearly 3 feet. There 
straight trunks may he seen without a limb, from 60 to 80 feet, the timber quite 
sound, and possessing that beautiful dark colour whence the species has derived its 
popular as well as its scientific name. When it grows on high mountains, as on the 
Delegate and Tingiringi Mountains, amongst rocks and precipices, it grows very 
gnarled and spreading, from 20 to 40 feet high, and from 1 to 2 feet in diameter, 
sending out thick, long, gnarled, and crooked limbs quite close to the ground. 
Mr. W. Bauerlen tells me that on the Delegate Mountain he has seen them as low 
as 1 foot from the ground, with the limbs of great length, and eventually touching 
the ground. Those trees furnish most beautiful timber, as far as grain and figure 
are concerned; but generally not quite so dark as the timber growing in the rich 
soil; but the situations are mostly inaccessible to vehicles of any kind. As regards 
the southern part of the State, the Clyde Mountains, Braidwood, and the Bateman’s 
Bay District, may he considered the most northern localities in New South Wales 
for Blackwood of commercial sizes. Thom thence it can he obtained all along the 
coast range right down to the southern boundary, where, as lias been already 
stated, it attains its greatest luxuriance in the brush country, in common with 
Sassafras, Musk, and other well-known plants. On the mountains east of Bomhala, 
Nimitybelle, and Cooma, hut yet on the high table-land, there is a belt of forest 
fringing the Monaro Plains. This forest, where it is intersected by its numerous
