IV. TIMBER. 



(a) Economics. 



This is the most widely distributed species of the genus, and its timber, 

 therefore, is more extensively used than that of any other Callitris. It is pre- 

 ferable to that of C. calcarata, R.Br., owing to its comparative freedom from 

 knots and its straighter grain, and so is in general request for certain parts of 

 house construction in the West and Central Divisions of the State. It is an easy 

 working timber, and although usually possessing a quiet neat figure, it occasionally 

 has some very handsome markings, which make it a valuable timber for some 

 kinds of cabinet work, such as panelling, &c. When polished it is very attractive, 

 and the decorative characters are well brought out in turned stands or columns 

 for busts, statuettes, &c. Some such adorn the landings of the Technological 

 Museum, and are a constant source of admiration to visitors. 



The white-ants or termites are not particularly partial to it, and will attack 

 it only as a dernier ressort, and this fact, of course, accounts for its utilisation for 

 fence and foundation posts, in which capacity it is reputed to be very durable. 

 The supply, unfortunately, of this most useful timber is gradually becoming less 

 and less, and no steps are being taken for its propagation. 



The following are results of transverse tests of timber specimens of C. 

 glauca of standard size (38 in. by 3 in. by 3 in.).
