APPENDIX. 241 



Euc. leucoxylon, rose-flowered variety, and 



Euc. amygdalina, var. angusti/olia, are the only two species 

 that extend beyond our extra- tropical limits, having success- 

 fully withstood the cold of 16 F. 



Have not seen the E. amygdalina tested upon poor soils. 

 The former, however, is very tenacious of life upon dry and 

 poor lands. 



Both make trees of the greatest magnitude. 



In cultivable lands, Euc. Gunni will make more rapid growth 

 than E. globulus, and hence is profitable for a fuel crop that 

 can be cut every four years. 



A few other promising sorts are, 



E. citriodora, for its essential oil. Dry exposures. 



E. paniculata. Dry exposures. 



E. punctata. Dry exposures. 



Most species of Eucalypti make good fuel ; a few are very 

 durable under ground or in water, and though largely used 

 in the antipodes for railway building, ties, etc., are in dis- 

 repute here from the tendency of some species to check and 

 warp, disabilities that can be overcome by cutting in proper 

 season and reasonable attempts at curing. 



Acacias. 



Upon any soil non-alkaline, and wherever the rainfall ap- 

 proximates sixteen inches, these are indicated for general 

 forest uses. 



They require but little assistance to be established, attain 

 marketable size in five to eight years, furnish an excellent fuel 

 (wood too small for most economic purposes), and some excel 

 all other trees in the quantity and quality of superior tan- 

 bark yielded to the acre. They have been fairly tested upon
