FOOT-NOTES TO EVOLUTION. 



grain and fruit have killed myriads more. A fortune of 

 ^25,000 offered by the New South Wales Government 

 still awaits the man who can invent some means of 

 general destruction, and the knowledge of this fact has 

 brought to the notice of the various colonial govern- 

 ments some very original devices. 



" Another great pest to the squatters is developing 

 in the foxes, two of which were imported from Cumber- 

 land some years ago by a wealthy station owner, who 

 thought that they might breed, and give himself and

 in evidence until within the last few years, when the 

 great destruction of indigenous birds by the gun and by 

 poisoned grain strewn for rabbits has facilitated its in- 

 crease. The devastation caused by these insects last 

 year was enormous, and befell a district a thousand
