{Grevillea robusta), sassafras {Doryphora sassafras), rose mahogany 

 {Synoum glandulosum), white wood {Schizomeria ovata) and others. 

 In North Queensland, under a heavy rainfall and on volcanic 

 soil, a similar profusion of soft woods occurs, of which the chief 

 species was the red cedar, now almost cut out, its successor 

 in pubUc favour being maple {Flindersia Chatawaiana), a fine 

 well-grown tree. Other species are silkwood {Fl. Mazlini), 

 kauri {Agathis Palmer stoni), satin wood {Dysoxylon Peltigrewia- 

 num), black walnut {Cryptocarya Palmerstoni), pencil cedar 

 {Lucuma galactoxylon), and others. 



The Hardivood Forests consist preponderatingly of Eucalypts. 

 On the moist sands of Fraser Island and the alluvial bottoms of the 

 south-east are found Euc. microcorys, pilidaris, saligna and tereti- 

 cornis. These are all useful building woods, 50 to 60 lbs. in weight 

 per cubic foot. On the drier ridges of the coast and in the near 

 west are found ironbark {Euc. paniculata, crehra, siderophloia) and 

 niaculata, all valuable, very heavy woods, weighing 60 to 80 lbs. 

 per cubic foot. Other associates are E. punctata, propinqua and 

 corymbosa. In the drier west, Acacias replace the Eucalypts. 



The Cypress Pine Forests. — -The cypress pine {Callitris glauca) 

 furnishes the domestic timber of Western Queensland and New 

 South Wales. It occurs either pure or under open ironbark, chiefly 

 in the sandy belts with 20 to 30 inches of rainfall. Drought and 

 fires have thinned them, and prickly pear has appeared in them. 

 The timber is a coniferous hardwood, aromatic, but somewhat 

 knotty and brittle. It is one of the few species which can be grown 

 under drought conditions, and therefore of special value to 

 foresters.
