222 FOREST CULTURE AND 
Throughout Europe and extra-tropical Asia, seventy 
feet high ; well adapted for river banks ; wood, soft 
and light, turning red, furnishing one of the best 
charcoals for gunpowder; it is also durable under 
water, and adapted for turners’ and joiners’ work. A. 
incana, Willd., is an equally high and allied species. 
Amyris terebinthifolia, Tenore.—Brazil. Is here 
perfectly hardy, and is content in dry ground, with- 
out any irrigation. It proved one of the best among 
the smaller avenue trees, is beautifully spreading 
and umbrageous, and probably of medicinal value. 
Angophora intermedia, Cand.—South East Austra- 
lia. This is the best of the Angophoras, attaining a 
height of fifty feet, and growing with the rapidity of 
an Eucalyptus, but being more close and shady in its 
foliage. It would be one of our best trees to line public 
roads, and to effect shelter plantations. 
f®. Baloghia lucida, Endl. (Codizum lucidum, J. M.)— 
East Australia. A middle-sized tree. The sap from 
the vulnerated trunk forms, without any admixture, 
a beautiful, red, indelible pigment. 
Betula alba, L.—The ordinary Birch of Europe and 
extra-tropical Asia. Itattains a height of eighty feet, 
and would here thrive best. in moist glens of the 
ranges, or in the higher regions of our mountains, 
where it would form up at the Alpine Zone excellent 
shelter plantations. The durable bark serves for 
roofing. Wood white, turning red. The oil of the 
bark is used in preparing the Russian leather. 
Betula nigra, L.—The Black or River Birch of 
North America. One of the tallest of birches. If 
grown on the banks of a limpid stream ; it will bear 
intense heat, The wood is compact, of a light color.
