240 ANIMAL COMPETITORS 



Fencing against other wild animals. Fen- 

 cing as a means of protection against wild an- 

 imals has for several years been in use in the 

 Australian colonies and in South Africa. In 

 Australia wire nettings are used successfully to 

 keep rabbits, dingoes, and some species of kan- 

 garoos out of pastures and crops. In Cape 

 Colony jackals are a great hindrance to sheep- 

 and ostrich-farming, and have been successfully 

 checked only by wire-fencing they could not get 

 over, nor under nor through. The expense of 

 such fencing -in our own plains country would 

 probably be $250 a mile; but it would pay for 

 itself, according to the South African experi- 

 ence, in the increased number of lambs reared, 

 fleece secured, health of the stock, improved 

 pasturage and less cost of herding. 



To those interested these arguments do not 

 need expanding nor expounding ; nor is it need- 

 ful to explain and discuss the recommenda- 

 tions for various designs of fence. The follow- 

 ing summary of recommendations made by 

 Special Agent Lantz, of the Biological Survey, 

 in 1905, are good for to-day, and have stood 

 the test of experience;
