a measure for the conservation of the red cedar (Cedrela toona). 

 This tree grows to a height of 100 to 150 feet, \yith a diameter 

 ranging from 3 to 7 feet, is easily worked, and is in dry situations 

 very durable. Some trees have been cut on the Eichmond river 

 yielding 30,000 feet of saleable timber. The market value of this 

 tree in Queensland is from twenty shillings per hundred superficial 

 feet, according to colour and size. It is only at open forest bushes 

 on the coast of New South Wales, on the Eichmond, Bellinger, and 

 Tweed rivers, that larger trees now abound. In 1881 and 1882, 

 this wood sold in London at 4d. and 5d. per foot. 



The Cypress pine of this colony {Fresnelia rhomhoidea) attains a 

 height of 50 to 70 feet, with a diameter of 20 to 40 inches. It 

 resists the attacks of the Teredo navalis and Termites. Its market 

 value in the colony is 10 s. per hundred superficial feet. The 

 brush or bastard box [Tristania conferta), growing to a height of 

 80 to 100 feet, with a diameter of 4 to 5 feet, also resists white 

 ants. Eiljs of vessels made of it were perfectly sound after thirty 

 years. 



When cabinetmakers are less chary of using new furniture woods, 

 they will find ample choice in Queensland. Beefwood and swamp 

 oak {Casuarina tondosa and C. equisitifolim), rosewood {Dyoxylon 

 Fraseranum), Myall {Acacia homalophylla), and others, specially the 

 bastard sandalwood (C Ereinophila Mitchclli), only claim attention 

 that their merits be recognised. 



There are about 4,000,000 acres of heavily-wooded land in 

 Tasmania, and thirty-four sawmills. The exports, hampered by 

 the protective duties of Victoria, are now confined almost entirely 

 to palings and small consignments of musk wood and hewn pine, 

 and were, in 1882, valued at £52,748.

 Many of these are extremely handsome, and all are most interesting.
