SHE-OAK SCALE. 61 



idea, as it will attack plants of Casuarina when these are 

 only 8 or 10 feet in height, so that persons going in for 

 plantations would do well to be on the alert ; a spraying 

 with some cheap deterrent, such as tar water, would most 

 likely prevent the young plants being attacked. As the 

 cultivation of such a valuable commercial timber as the 

 She- oak is sure to be largely extended in the near future, 

 it behoves all to keep a keen lookout ; when a large tree is 

 attacked (I have seen thousands of galls on one tree), there 

 is but little hope of successful treatment. 



This pest has been found growing plentifully on trees in 

 close proximity to orchards, but, as before stated, it has, so 

 far as we know, kept to the She- oaks both of the common 

 kinds. Although this is one of the most valuable and 

 handsome of the native trees, it would be well to remove 

 them if found growing near to an orchard, and the same 

 remark would apply to Wattles.
