purposes for which that wood is used, and is more 

 easily wrought. It is sometimes called " Iron-bark 

 Box." One hundred to one hundred and fifty feet. 



18. WooLLEYBUTT {E. longifoUa). — An average- 

 sized tree. Fair timber for fencing and building pur- 

 poses ; it is a good fuel for domestic use ; very dura- 

 ble, and is said to be less liable to the attack of the 

 white ant than any other of the Eucalypti. One hun- 

 dred to one hundred and twenty feet. 



19. BiiOODWOOD {E. corymbosa). — A very large 

 tree. Timber first-class for posts, piles, and such like; 

 it is extremely durable in the ground. It is not a 

 favorite as sawn timber, on account of its many gum 

 veins ; not a good fuel. One hundred and fifty to 

 two hundred feet. 



20. Swamp Mahogany {E. robusta). — A good last, 

 ing timber for house - carpentry and many kinds of 

 turnery. It is not durable in the ground, but for other 

 purposes it is very durable, and is not a favorite with 

 the white ant. It is not remarkable as a burning 

 wood. Its specific gravity is great. One hundred 

 and fifty feet.

 In the once despised Gum-tree (Eucalyptus) it has 

 been discovered that qualities exist which place it 

 transcendently above any other plants, if not above 

 all other plants, in hygienic importance. 



By its means large tracts of the very richest land 

 will be made available in many parts of the world. 

 In India, and other parts of Southern Asia, vast areas 

 are left without culture or occupation, overrun with 

 jungle and forest, and totally unfit for man's abode 

 on account of their malaria-producing character. A1-,
