240 APPENDIX. 



No. 3, Eucalyptus virinalis, and less than one per cent, of 

 the other species. 



No. I, by reason of its more rapid growth, has been most 

 freely planted. It is confined to the thermal belt, suffering 

 when young from low temperatures (2 to 4 F. of frost). 

 Nos. 2 and 3 are much hardier, and are equally resistant of 

 drought. 



All will grow upon arid hills, but only make remunerative 

 growth where the subsoil is of an open, porous nature ; the 

 root must have an opportunity to get down. Upon rock or 

 impervious subsoils these three gums may be seen, fairly 

 vigorous, but not averaging over twelve to fifteen feet, now 

 with stem diameter of over two and a half inches, representing 

 five and six years' growth. Eesults about equal to one year 

 upon open, porous soils of fair quality. 



In value for fuel or timber, they take precedence as 

 follows : 



E. rostrata, 1. 



" globulus, 2. 



" virinalis, 3. 



The former is reputed to be " teredo"-proof ; but there is 

 no timber as yet within the State large enough for wharf 

 purposes. 



In a smaller way, tests have been made with other species ; 

 the following prove of greatest merit : 



Euc. corynocalyx (Sugar Gum). Hard and durable timber. 

 Tree umbrageous, endures drought and sterile soils. Suscepti- 

 ble to light frosts. 



Euc. diversicolor, characteristics not dissimilar from last. 



Euc. populi folia, smaller tree than last, but hardier.
